Are you looking for File/Printer Sharing and High-Speed Internet Access? 

Do you want to be able to share a printer or files with all of the other computers in your business? Do you want high speed Internet connectivity? How about sharing streaming Audio or Video files among computers? If so, then Computer Networking is for you.

At ADI we take the time to explain the different options for cabling and Internet connectivity to help you make the right choice for your business. Call or email today for a free quote or read on for more information.


Businesses of all sizes have a computer network today. With a computer network, you can share data and printers, digital photos, video, and music with other computers in your business. The network can be a server-based network using a Windows NT/2000/2003/2008/2012 or Linux server, or Network Attached Storage (NAS). Also, with high-speed Internet access becoming commonplace, a computer network makes a lot of sense. By adding a device called a router, all of the computers in the business can get high-speed access to the Internet at speeds from 1 Mbits/sec to 155 Mbits/sec or more. The most common options for business Internet connections are DSL and Cable Modems for small businesses and T1 (1.5 Mbit/sec) or DS3 (45Mbit/sec) up to 1 Gbps for larger businesses. The most common networking technology for moving data around your business are Etherent (10 Mbit per second and rarely used today), Fast Ethernet (100 Mbit per second), or Gigabit Ethernet (1000 Mbit or 1 Gigabit per second). These technologies run over 4 pair cabling as follows:

  • Category 3 cabling - Ethernet
  • Category 5 cabling - Ethernet, Fast Ethernet, or Gig Ethernet (with some limitations)
  • Category 5E cabling - Ethernet, Fast Ethernet or Gig Ethernet
  • Category 6 cabling - Same as Category 5e but made to a higher standard
  • Category 7 cabling - Same as Category 6 but made to a higher standard. This cable is shielded and will have a different connector (not a standard yet)


No matter what technology you choose for connecting to the Internet, or what operating system you choose for your network, you will want to run Ethernet between your computers. Ethernet has been around since the mid-eighties, and is by far the most popular option. Ethernet runs at 10 Mbits/second, and will run over Cat 3 or above cabling. Ethernet's big brother, Fast Ethernet, runs at 100 Mbits/second, and will run over Cat 5 or above cabling. Cat 5E fixes a near end cross-talk problem that is in some Cat 5 cables, and is preferred for Gigabit Ethernet. In reality, Fast Ethernet is more than enough for most business networks but since most products today support Gigabit Ethernet, you might as well use it. Most business class computers have an Ethernet adapter as a standard option which uses an RJ-45 connector and will allow you to connect it to the Ethernet network. You will need a device called a switch to connect multiple devices together. Ethernet is an IEEE standard (802.3), and the standard calls out a 4 pair (8-wire) cable. In reality, Ethernet only uses 2 pairs of wires, one for transmit and one for receive (Gig Ethernet uses all 4 pairs). At ADI, we recommend running a Category 6, 4-pair cable, home run to your data center. We usually run a Cat 6 cable for network to all locations that have a phone.


A switch is a device that inter-connects all of the PCs, servers and printers together so that they can communicate with each other. There are many options available here, but the main options are speed and managed or non-managed. Most low end switches today will support 10/100/1000 Mbit. Most low end switches are non-managed which means that you really have no way to look into the switch and see what is going on when things go wrong. Managed switches usually have a web interface so you can connect to the switch, configure it and also troubleshoot the network when things do go wrong. Switches can be purchased with 4, 5, 8, 16, 24 or more ports. High end switches are expandable so you can add more ports as your network grows.


In addition to running Cat 6 cabling all over your building, you could choose to add wireless. There are wireless options that are cheap and easy to install that run up to 600 Mbit/sec (802.11n). To make this work, you will buy an Access Point that will connect into your network, and a wireless Network Interface Card (NIC) for each PC that will be connected to the network. Most laptops, desktop computers and tablets are being sold with a wireless NIC built-in as a standard option. When using a wireless network, security is an important consideration. There are easily available tools on the Internet that allow you to snoop the airwaves and look for wireless access points. If you just buy a wireless access point and install it in a default configuration, ANYONE will be able to connect to your network and possibly hack into your computer systems. Here are some of the terms you will see in your access point:

  • Service Set identifier (SSID)--This is the name of your network and should be changed from the default. With easily available tools found on the Internet, you can sniff this name and if it is the only security you are using, it is not effective at all. Let’s say you buy a Linksys access point and leave the SSID at the default, and someone in a neighboring business buys a Linksys wireless NIC card. Since they have the same defaults, he will be able to connect to your network. If you change the SSID, it at least makes it slightly harder. Keep in mind you have to change it on both the access point and all wireless network cards in your business.
  • Wired Equivalent Privacy (WEP)--WEP is an encryption algorithm whereby you setup an encryption key on both the access point and the wireless network cards. As data is transmitted it is encrypted (scrambled) and then decrypted (unscrambled) as it is received at the other end. WEP is rarely used anymore.
  • Wireless Protected Access (WPA) v2--WPA v2 is newer standard that still uses WEP, but it dynamically changes the key every so often. The idea is that by the time a hacker has hacked the WEP key, it is no longer valid. You should always use WPAv2 if it is available. Some older network cards and Access Points do not support WPAv2. Check the manufacturers web site and there may be a firmware update you can download to enable WPA v2.

Network Attached Storage (NAS)

Instead of using a Windows or Linux server, a NAS is a great choice. In a small network, the server is usually only used as a print server and as centralized storage. Today's NAS products from Netgear, Western Digital, Lacie and others can act as a print server and have lots of storage and are much cheaper and easier to maintain than a server. Usually they will have RAID which guards against data loss. With RAID, if a single hard disk fails no data is lost! They are available in sizes from a few Gigabytes to 10 Tyrabytes or more.


If you have a connection to the Internet, you MUST use a firewall. A Firewall is a device that allows connections out to the Internet, but does not allow people to connect in to your network from the Internet. There are many options here, but Cisco, Checkpoint and Juniper are popular firewall options in large companies with Linksys, D-Link and Netgear being the most popular for small business use. You can buy models that have a 4 or 8 or 16 port switch, a wireless access point, and a firewall all in the same product on the low end. Or you can buy just a stand alone firewall and connect it in to your switched network.


DSL (Digital Subscriber Line) is a technology that can piggy back high speed data services on to one of your existing phone lines. There are many types of DSL, all with different speed capabilities, and all incompatible with each other. The speed that you get depends on how far away you are from the Telephone Company, and how much money you want to spend. Speeds can be up to 50 Mb/second and may be asymmetrical (different speed in-bound than out-bound). Ask your Telephone Company if DSL is an option in your area, and what speeds are available. You get a DSL modem as part of the service, which has an incoming phone line connection, a phone output, and an Ethernet connection.

Other Telephone Company Options 

For medium and large sized businesses, your Telephone Company will have options from fractional T1 (1.5 Mbit/sec) to fractional DS3 (1.5 Mb to 45 Mb) to DS3 (45 Mb) to OC3 (155 Mb) or larger. Call your Telephone Company to find out pricing.


Cable modems connect to the cable TV system, and give you a high-speed connection to the Internet. If it is available in your area, you will get a cable modem that connects to the cable TV system, and has an Ethernet connection for connecting to the computers in your business. The speed can vary, but is usually in the 5 to 50 Mbits/second range. Most cable systems have been engineered or re-engineered to be bi-directional, but typically the speed you get from your cable modem will be asymmetrical. It will be faster for downloads than for uploads. Also, Cable TV providers are now offering telephone services bundled together with high speed Internet access. Ask your Cable TV operator for details. Cable is typically used in small or medium sized businesses.

Wireless Broadband

Cellular companies like Verizon, AT&T (Cingular) and Sprint have a service that allows you to connect to the Internet by putting a  card in to your laptop. But companies like Kyocera and D-Link make routers that will allow you to plug that card in to them. So as long as you are in Cellular range, you can use one of these routers and service to get Internet connectivity for many computers at once. Speeds can be from 1 Mbit/sec up to 20 Mbit/sec for 4G service. This is a great option for small businesses in remote areas where no other option is available, or for temporary networks like at a customer's site or a trade show.


A Cleaner and Healthier Business?

A Central Vacuum System will make cleaning your business quick and easy. It will also keep the air quality healthy by taking the dirt and dust out of your building. This is a popular option for smaller offices and Hair Salons.

ADI can install a Central Vacuum System in your business or service your existing system. Call or email today for a free quote! Keep reading if you would like to know more about Central Vacuum Systems.


Central Vacuum systems have become very popular over the last few years. Typically, Vacuum inlets are installed around your business, allowing coverage of the entire building. Instead of dragging a heavy Vacuum around, you have a light weight hose and Vacuum head that is easy to use. The main suction unit is installed in the mechanical room or warehouse. Also, Central Vacuum systems will help in keeping the air quality inside your building clean. With a normal vacuum, pollen and micro dust particles escape the bag as you vacuum and become airborne for all to breath. With a Central Vacuum system all of the dirt, dust and pollen are taken out of the building and into the mechanical room. Finally, the exhaust from the Central Vacuum can be vented to the outside of your business to make sure that all micro particles end up outside of the building. The main unit is bigger and more powerful than a standard Vacuum.


Central Vacuum systems are typically installed in new construction, while the walls are open. They can be installed in existing buildings, but the price of labor can get high. You would typically have some number of Vacuum inlets, PVC pipe that runs from these inlets to the main unit, the main unit itself, and some accessories (see below).


The Central Vacuum system consists of the following parts:

  • In-wall inlets: The standard in-wall inlets are mounted in the wall, and are positioned around your building so that you have coverage of all floor surfaces. There are two types of inlets. Integrated power or external power. To make the difference more clear, lets look at the parts of a normal Vacuum. In a normal Vacuum, you have a motor that provides suction, and one that provides brush rotation used to beat the carpet (sometimes one motor does both functions). With a Central Vacuum system, the unit that supplies suction is mounted in a central location (mechanical room). Since the head unit of the Central Vacuum requires power (110 volts AC) to function, it must be supplied by the system. With the integrated inlet, the 110 volts is supplied through contacts in the inlet. So, when you plug in the hose, that's the only connection you need! With the external power inlet, you must plug the hose in to the inlet on the wall AND a normal 110 volt plug into a standard electrical outlet nearby. The integrated power inlet is the best and most convenient way to go. The external power inlet is often used in existing construction, since no electrical work is required. 
  • Suction Powered head unit: A newer option offered by Dirt Devil uses the suction of the main unit to turn the brush in the head unit. So there is no need for AC power to the head unit at all! The good news is that you can save money by not having to have AC power at every inlet. The down side is that it takes a small amount of time for the brush to spin up when you turn on the system.
  • Vacuum-pan inlets: A Vac-pan inlet is typically used anywhere that you have hard floor surfaces (tile, hard wood, etc.). They are mounted at the floor level, either in the wall, or in the bottom of a cabinet. The idea is that you would sweep the floor with a normal broom, push the "on" switch on the Vac-pan with your foot, and then sweep the debris into the Vac-pan, which is then sucked in to the main unit's filter.
  • The main unit: The main unit of the Central Vacuum system is the unit that provides the suction and filtering for the system. All of the inlets in the system are terminated at this unit, which could be mounted in the mechanical room. In large buildings, multiple main suction units may be used. Some of the options you will have in selecting this unit would be the power and the filtering system. Most Central Vacuum manufacturers have several models with different amounts of suction power. The difference in power really is just based on the size of the system (number of inlets and length of pipe used). The filtering system is a matter of preference. They will either use bags (like your normal vacuum) or be a bag-less system that holds the debris. I like the bag-less systems, so that you don't have to worry about buying and replacing bags. Also, some systems have micro filters to catch and trap even smaller particles. At ADI we proudly install Beam and Dirt Devil Central Vacuum systems.

Here are some of the things you will be asked to buy with your Central Vacuum system:

Hoses can be purchased in different lengths, like 25 or 40 feet. If the inlets are positioned correctly, the 25 foot length should be fine.

  • Hose sock: If you have hard wood floors, dragging the hose across it can scratch the floor. A hose sock is a soft cloth cover that installs over the hose to keep it from scratching the floor.
  • Tool kit: This kit typically has things like a crevice tool, upholstery tool, floor tool, etc.
  • Car Kit: This kit has tools that are made specifically for cars like a small powered head and different crevice tools.


Wouldn't it be nice to check on your business while you're at home or away on vacation?

The alarm company calls you at home to inform you that the alarm at your business is going off. You go to your computer, or use your iPhone or Smartphone and pull up the cameras. You see that it's just the cleaning crew, so you call them to make sure everything is OK. You just saved a call to the police!

There are many options here and we can help you make sense out of it all. Call or email us today for a free quote or read on for more information:


Cameras around your business have a variety of applications. Want to see what employees are doing when you're not there? Want to check on your business while you are away? Want to record the cameras so you can see what happened yesterday? These scenarios and others are all possible. Basically you would use some cameras, and some type of device to convert the video in to a web based stream or to get the video on to a TV or touch screen controller screen. You can also view the cameras from your iPhone/iTouch/iPad or Android Smartphone!


There are many options here. The first thing to consider is do you want a Web Camera or a standard camera with video output?

  • Web CameraThe web camera is a single camera that has a Web Server built in. Once you give it an IP address, you can point your browser at the device and you will see the image on your computer. Some web cameras have pan/tilt/zoom capabilities. There are also wired (via Ethernet) and wireless (802.11) models. The down side is that if you need multiple cameras, you will have to point your browser at multiple IP addresses to see each camera. Most newer web cameras allow you to see multiple cameras in a single web browser window, but they are more expensive.
  • Standard Camera with Video outIn this case, you would have several wired cameras around your business. These cameras have a composite video output that can easily connect to a single TV, all TVs in the home (via video distribution) or to a color touch screen controller. Cameras are available in color, B/W, and with or without night vision. Night vision cameras allow you to see images even in low or no light situations. The down side is that typically you can't get pan/tilt/zoom capabilities and you need another device to get these cameras on the Web (see below).
  • IP Based CameraIP cameras connect directly in to your Computer Network. Then a server appliance installed on the network would allow you to record and view the cameras remotely.
  • 360 Degree Camera--A new option is able to look in all directions in a room at once without moving! So instead of the old cameras that would rotate around to cover the whole room, the new digital versions don't move and can see in all directions at once!
  • HD Cameras--HD cameras have much better resolution and are useful in some situations where you need to see more detail.

Video Server

A video server device will take in a standard composite video signal from one or more cameras and convert it to some format as follows:

  • Web serversA web server from companies like Axis will take in four or eight video cameras and allow you to view them from anywhere via the Internet. It could also have DVR capabilities so you can record the cameras (see below).
  • DVRA DVR (Digital Video Recorder) from companies like Dedicated Micros will take in 4, 8, 16 or more cameras and allows you to record and watch the live or recorded image on a TV. It could also have a Web Server built in (see above). Some of the options will be number of cameras supported, size of the hard drive (which equals how many days of video it can store) and does it have a web server or not.
  • Video ServerA video server is a server that can store and serve up video and is typically used in a system with IP cameras.

Internet Connectivity

In order to be able to view your video cameras remotely, you will have to have some form of high speed Internet connectivity like DSL, Cable Modem, ISDN, T1 or higher, ETC.

Internet Router/Firewall 

You will need to configure your Router or Firewall to allow in-bound connections to the camera server. Firewalls by default will only allow out-bound connections. Most Firewalls (but not all) will allow you to configure it to allow in-bound connections. Check the documentation that came with your Firewall or call us and we can take a look for you.

Lighting Control can save time, money and make your business more secure.

Would you like to have a single button on a keypad or touch screen controller that turns on/off all of the lights in your showroom or office? Do you want lights to turn on and off during the night for extra security? How about controlling lights from your iPhone/iPad or Smartphone? Or have lights turn off in a room after 10 minutes if no motion is sensed?

These are just a few of the things that you can do with lighting control systems. Call us today for a free lighting design quote or read on for more information:

Lighting Control Basics

Lighting control can be as basic as a timer that you plug a lamp into and it turns on and off at a preset time every day. A more sophisticated control system would track the changing time of sunrise/sunset or sense darkness and adjust the on/off times so that the lights always come on around dark.

Lighting Scenes

Lighting scenes allow you to group lights together so that a single button push on a keypad or touch screen controller can set the "scene". So each light in your business can be turned on and set to a specific dim level. Here are some examples:

  • You come in to your business in the morning and push a single button to turn on all of the lights in the office
  • As you leave your business at night, you arm the alarm system and all of the lights in the building go off automatically
  • You enter a conference room and by pushing a single button, the lights come on, the window shades are lowered, a video screen comes down out of the ceiling, and the projector turns on. 

Lighting Technologies

Lighting control basically comes down to two things. The lighting modules and the lighting control system.

  • ModulesThe lighting modules are the devices that actually control the light itself. So for a lamp there would be a light module that would plug into a standard A/C outlet and the lamp would plug in to the module. For a chandelier or recessed lighting, there would be an in-wall switch that looks just like the standard wall switch that you are used to. But these devices would be controllable by the control system. These modules could be wired or wireless and controlled via a variety of different communication technologies.
  • Control SystemThe control system will have the ability to control the lighting modules. By issuing commands, the controller can turn lights on/off or dim/brighten them.
  • Communication ProtocolsCommunication protocols are the mechanisms used by the control system to talk to the lighting modules. Some protocols are one-way and some are two-way. In a one-way protocol, the controller would issue a command (light on for example) and just hope that it actually happened. A two-way protocol allows for the module to respond to the command (yes I turned the light on). Some communicate over the standard 110 Volt A/C wiring in your business. Some communicate via wireless and some are hard-wired. Here are some of the more popular communication protocols:


  • X10 is a one-way protocol that has been around since the early 1970s. It is still in use today. It is cheap and easy to find, but not very reliable, especially in businesses.
  • CE Bus is a two-way protocol that is faster and more robust than X10. It has been around since the mid 80s. It is more expensive and more reliable than X10, but still rarely used in businesses.


  • Radio Ra is a two-way proprietary protocol developed by Lutron. It is medium priced, easy to install and very reliable.
  • Zigbee is a low-cost, two-way wireless mesh network protocol. It is standards based, however interoperability between manufactures is not guaranteed. It operates in the 2.4 GHz or 915 MHz spectrum. Control4 uses this technology 
  • Z-Wave is a low-cost, two-way wireless mesh network protocol. It is standards based and available from many manufacturers. It operates in the 900 MHz spectrum.


  • Lutron Homeworks is a two-way proprietary protocol developed by Lutron. It is a high priced, extremely reliable, and very scalable system.


We install lighting products from Lutron and Control4. These companies have controllers and keypads to control their lighting systems. But what if you have an automation system and want to integrate lighting control in with that system? Not to worry, as there are a few ways to do this. It can be done either via IR or RS-232. So for example an Elan or Control4 touch screen controller can be setup to control audio/video, your alarm system, your thermostats and your lighting. The control system will talk to the Lutron system via RS-232.

Call us today and we can put together a lighting control system that completely addresses your needs.

What is your business worth to you?

Security systems are really quite inexpensive when you consider how much money they can save you. The system can use sensors that detect not only intruders, but carbon monoxide, smoke, and water or cold temperatures. This will not only protect you and your assets but it can also protect your business from damage and even save your life! At ADI we give you the choice of having the system monitored for a monthly fee or just as a stand alone system. With automation options you can check the status of your system, view cameras over the Internet or receive an email when the alarm is armed, disarmed or triggered! Check on your business from your iPhone/iPad or Android phone! 


ADI can install a security system to protect you and your business from a variety of threats. We can also add Surveillance Cameras for extra piece of mind. Call or email today for a free quote! Keep reading if you would like to know more about Alarm Systems.

Security systems are available with a wide range of features and at a wide range of prices. Let's talk about some of the things that you may want to consider when selecting an alarm system.


In a hard-wired system, wires are run from every sensor in the system to a main control panel. Most Commercial Installations will use this option since it is easy to run wires above the dropped ceiling typical in most businesses. If you have hard to reach areas, or a very large facility, then a wireless system will usually make the most sense. In a wireless system, the sensors are not hard wired to the main control panel. Instead, they transmit radio signals to the main control panel. The bottom line is that in a wired system, the hardware is cheaper, but the installation is more expensive than the wireless system. Wireless systems are less reliable and have more on-going maintenance since all of the sensors have batteries that will need to be replaced from time to time.


Once you have determined whether you will use a wired or wireless system, the next thing to consider is how many zones the system will handle. Usually, every sensor in the system will require a zone. Control panels can be purchased with 8, 16, 32 or more zones. Some control panels have some number of wired zones AND some number of wireless zones. Most all panels are expandable so that more zones can be added later. In the higher end control panels, you can get features like relays and lighting control. This allows you to do things like turn on lights in a room when a motion sensor detects movement or close the overhead door from the alarm keypad. At ADI, we proudly install DSC alarm systems.


  • Door sensors--Most alarm systems will start with door sensors on all of the main doors. Door sensors are recessed into the door jam, so that you can't even tell that they are there! You can also put a door sensor on your overhead Garage Door in your warehouse. With an alarm sensor on it, a quick look at the alarm keypad on your way out will let you know that the door was left open.
  • Motion Sensors--Next, you would add some PIR (Passive Infrared) motion sensors. These sensors must detect both a change in temperature and motion to trigger an alarm. This dual action cuts down on false alarms. 
  • Perimeter Sensors--Perimeter sensors are used to secure outdoor areas like a parking lot. There are many different technologies like IR, Microwave or Laser available here.
  • Glass Break Sensors--Glass break sensors are basically microphones that "listen" for the frequencies that make up the sound of breaking glass. Glass break sensors can either attach directly to the window, or can mount on a near-by wall or ceiling covering multiple windows with a single sensor. Window attached glass break sensors are rarely used anymore.
  • Smoke Detectors--Smoke Detectors and heat detectors can be used to safeguard against fires. We can add sensors to various areas of your business or if you already have a fire system in place, we can connect a relay output from that system to our system.
  • Temperature Sensor--If your business sits empty for some period of time, you might want a low temperature sensor. If your heating system fails in the winter then the alarm system can let you or the central station know that the temperature is below a safe level, say 40 degrees. This could save you a lot of money if it keeps your pipes from freezing.
  • Carbon Monoxide Sensor--A Carbon Monoxide sensor can be added to the system so that you will be alerted to the presence of deadly carbon monoxide gas. Carbon Monoxide gas is colorless and odorless, and can kill you if levels get too high.
  • Water Sensor--A water sensor will alert you if it senses water due to a broken/frozen pipe. We can even set it up to shut off the water to your business if it senses water! This can save you thousands of dollars in the event of a water leak.


Keypads are the devices that allow you to arm and disarm the system, and give you feedback as to the status of the system. Usually you would put a keypad by each exit/entry point. Standard keypads have LEDs that let you know which zone has been tripped. We recommend using upgraded keypads that have an LCD display. Instead of telling you that "zone 1" has been tripped, it tells you in clear text that "Front Door" or "Warehouse Motion Sensor" has been tripped. This way, you know exactly which sensor is causing the alarm without having to remember what sensor "zone 1" represents.


In addition to or in place of Keypads, you can connect the security system to a control system. This allows you to use a Touch Screen Controller to control the alarm system. So the same Touch Screen controller that you use to control your conference room or lighting can also be used to arm/disarm and monitor your alarm system and view surveillance cameras around your business! There are also web based options so you can control your alarm system and view cameras remotely using a web browser.


A Control4 Touch Screen Controller can be used to control everything including your Alarm System and even view Surveillance Cameras!


You can choose to have your alarm system monitored if you want. That means that if your alarm is set off, the system will dial up a central monitoring station, which in turn will call you and the police or fire department.


With standard monitoring, your phone line is used to dial the central station when an alarm is triggered. A professional thief may cut the phone line before he breaks in to your business (if it is accessible) so that the system can't dial the central station. To guard against this, a wireless dialer or network based backup can be used. This would use cell phone technology or the Internet to alert the central station if the phone line is cut.


Cost can be set up two ways. Some of our competitors install the alarm system for free, but force you into a monthly monitoring contract for 3 or more years. Prices can be as high as $89.95 per month. Typically, you don't own the equipment at the end of the time period, you are just renting the equipment! At ADI, we charge for the alarm system, but allow you to choose whether you want monthly monitoring or not. Typical cost for the system and installation is $750.00 to $1,800.00 depending on the number of sensors and features. Monthly monitoring is $39.95 per month if you choose to have the system monitored.
