Access control systems
An access control point can be a door, turnstile, parking gate, elevator, or other physical barrier where the granting of access can be electrically controlled. Typically the access point is a door and the access is controlled through either a magnetic lock or electric strike
Proximity Card Technology
The typical proximity card consists of a microchip and antenna embedded in a plastic card. When the card is placed within the radio field of the reader, the energy broadcasted from the reader energizes the microchip on the card and begins a transaction between the card and reader. When the reader recognizes the card, the card is queried for the identification number. A proximity card can be passive or active. An active card has a battery to power the microchip and is usually thicker than the standard ISO plastic card. A passive card depends solely on the radio field of the reader for power giving it less range but longer useful life. Proximity readers have been steadily gaining in popularity because of the ease of use, lack of wear, and high tech image. The cards are very difficult to duplicate because of the need for the microchip, knowledge of radio technology, and the software needed to implement the protocol. The minor problems associated with this technology are occasional problems with RF interference and the fact that it may be easier to follow someone with valid access through a door because the read range may make it more difficult for a guard to verify that a person has or has not presented a card. 
Smart Card
There are two types of smart cards: contact and contactless. Both have an embedded microprocessor and memory. The smart card differs from the card typically called a proximity card in that the microchip in the proximity card has only one function: to provide the reader with the card’s identification number. The processor on the smart card has an operating system and can handle multiple applications such as a cash card, a pre-paid membership card, and even an access control card. The difference between the two types of smart cards is found in the manner with which the microprocessor on the card communicates with the outside world. A contact smart card has eight contacts, which must physically touch contacts on the reader to convey information between them. A contactless smart card uses the same radio-based technology as the proximity card with the exception of the frequency band used. Smart cards allow the access control system to save user information on a credential carried by the user rather than requiring more memory on each controller. 
A personal identification number (PIN) falls in the category of what you know rather than what you have. The PIN is usually a number consisting of four to eight digits. Less and the number is too easy to guess. More and the number is too difficult to remember. The advantage to using a PIN as an access credential is that once the number is memorized, the credential cannot be lost or left somewhere. The disadvantage is the difficulty some people have in remembering numbers that are not frequently used and the ease with which a PIN can be observed and therefore used by unauthorized people. The PIN is even less secure than a bar code or magnetic stripe card. 
CCTV, CCTV Camera, CCTV Surveillance Camera, CCTV Micro Dome Camera. A Closed Circuit Television (CCTV) is a video magnification system consisting of a video screen interfaced with a video camera. Video magnification is achieved in two ways: 1) the electronic conversion from the small camera image to the larger display screen and 2) the optical effect of the cameras zoom lens. The stand mounted CCTVs can be configured with television receivers, video monitors, or computer monitors. The image magnified on the CCTV's display may provide enhanced contrast and brightness, inverse video display, gray scale, false colours, and natural colours. This CCTV accommodates a variety of monitor sizes. Also available in optional 15" or 20" flat LCD screen.

3. Video surveillance
Video surveillance cameras are becoming more popular and, most importantly, more accessible to the average person. Huge store chains or gated communities aren’t the only places than can afford the benefits of surveillance cameras anymore. They are available for your home and office needs, no matter how simple or how elaborate a setup you require.
Types of cameras available for video surveillance:

You have a broad range of video surveillance cameras available to you. Understanding the different kinds will make it easier to determine which one suit you best.

  • Fake security cameras – These are not actual cameras. They are a very inexpensive alternative to purchasing an actual system. While these cameras can act as a deterrent, should something happen, you will not have a record of it.
  • Covert surveillance cameras – These cameras look like regular items. A wall clock in a small store, a teddy bear in a baby’s room, a potted plant by the front door—each one of these could very easily be a surveillance camera. You can record without anyone knowing it.
  • Wireless security cameras – These offer more flexibility in set up. They are easy to install, can be moved easily, are often small, have no tell-tale wires, and are very discreet.
  • Wired surveillance cameras – These cameras are appropriate for permanent setup. If you have one location that you would like to constantly monitor and will not need it to be changed, a wired camera is an option. Some may have to be professionally installed.
  • Night vision security cameras – These are ideal for any low-light areas, not just for the night time. The camera records in black and white in order to capture images best.
  • Home surveillance cameras – When you buy a setup for home, you get a helpful system that often includes such bonuses as timers for your lamps and motion sensors to go with the wireless camera.
4. Wireless security cameras
Wireless security cameras are fast becoming the best option for security camera installation. Whereas once wired cameras were the only option, wireless security cameras present new options for your security needs. Your security matters and you deserve flexibility in the installation and use of your security camera.

Improved flexibility – A wireless camera can be moved to different locations while a wired camera is difficult to move once it is installed.

Temporary setup – The cost effectiveness of a wireless camera makes it ideal for a security situation that does not need constant monitoring, like a seasonal location such as a pool.

Appearance – If you want a security camera in your home, office, or store, a wireless camera, as the name suggests, gives you the security without all the wires running around your home for an inconspicuous and more attractive appearance.

Wireless security cameras come in many different sizes, which also helps make them a more viable security option. A small, discreet camera is more apt to record the normal activities than a large, hulking device for the simple fact that people act differently when they know they are being recording. If you want to know you’re getting the most accurate results from your security camera, a wireless security camera is for you.

Wireless security cameras are available in black and white or color, with color providing a more identifiable image. Improvements in camera technology have made a wireless color camera just as affordable a black and white one. Most cameras have a great range of up to 100 feet, so you will be getting feed from a sizable space with just one camera.

  • Smoke detection
• Motion sensors (which can be pet proof)
• Glass break sensors
• Panic buttons
• Light sensors for lamps
• Sirens when the alarm goes off
• Window and door sensors to detect unusual movement
• Voice dialing when the alarm is triggered
6. Burglar alarm

Sensors are connected to a control unit via either a low-voltage hardwire or narrowband RF signal, which is used to interact with a response device. The most common security sensors indicate the opening of a door or window or detect motion via passive infrared (PIR).

A burglar alarm control panel is a wall-mounted unit where the detection devices and wiring of the alarm are ultimately connected and managed. These includes devices such as bells, sirens, door contacts, motion detectors, etc. Typical panels are located in utility closets or access rooms

7. Digital recorder
The digital video recorder server is a great new innovation in the world of closed circuit television surveillance. Digital video recording is becoming widely popular because it gives you so much freedom in recording. With the latest video server technology, you can actually view live action or action that you have already recorded while continuing to record. Reviewing will never come at the expense of present recordings.

Installing a digital video recorder (or DVR) server allows you to save space and time. Other recording servers require several different pieces of equipment in order to get the results you will get from a single DVR server. This combination device replaces the time-lapse VCRs, the multiplexer that allows multiple signal inputs and the video server necessary for remote surveillance. That sounds like a lot of complex equipment, doesn’t it? Imagine getting all of that in one slim, comprehensive unit.

Digital video recorder servers typically have four, nine, or sixteen security camera inputs, giving you the flexibility to implement whatever camera system suits you best. Other great benefits and features include:

  • Remote access at all times
• Better pausing for still images
• Improved storage, especially over long periods of time
• Easy installation
• Clear image copying
• Long recording times
• Internal web server
• Picture in picture and zoom
• Hard drive for storage
8. Intercom systems
We offer a large selection of Wired / wireless intercom systems for use in the home, office, or outdoors. We offer portable wireless intercoms, wall flush-mount wireless intercoms, outdoor waterproof intercom systems, and long-range wireless intercom systems.

An intercom (intercommunication device) is an electronic communications system intended for limited or private dialogue, direction, collaboration or announcements. Intercoms can be portable or mounted permanently in buildings and vehicles

Master Station or Base Station - These are units that can control the system, i.e., initiate a call with any of the stations and make announcements over the whole system.
Sub-station - Units that are capable of only initiating a call with a Master Station but not capable of initiating calls with any other stations(sometimes called slave units).
Door Station - Like sub-stations, these units are only capable of initiating a call to a Master Station. They are typically weather-proof.
Intercom Station - Full-featured remote unit that is capable of initiating and receiving party-line conversation, individual conversation and signalling. May be rack-mounted, wall-mounted or portable.
Wall Mount Station - fixed-position intercom station with built-in loudspeaker. May have flush-mounted microphone, hand-held push to talk microphone or telephone-style handset.
Belt Pack - portable intercom station worn on the belt. Requires a headset or handset.
Handset - permanent or portable telephone-style connection to an intercom station. Holds both an earpiece and a push to talk microphone.
Headset - portable intercom connection from a belt pack to one or both ears via headphones with integrated microphone on a boom arm. Connects to a belt pack.
Power Supply - Used to feed power to all units. Often incorporated into the design of the base station.

9. Multiplexers
Video multiplexers take multiple camera signals and combines them onto one channel so you can record them on a recording system of your choice (i.e. VCR, DVR, DVR software, etc.). For example, if you have four security cameras, each of those signals is synchronized with the multiplexer and recorded on the same tape. This makes your security system easier to manage because the multiplexer works with the VCR to put all your recordings in one place.

You can choose your video camera multiplexer based on the number of camera inputs you need, keeping the potential growth of your system in mind. Multiplexers come with a number of great benefits and features. Possible features of your multiplexer include:

  • An alarm output, should suspicious activity take place
• Time and date stamp, so you always know when any recorded activity took place
• Motion detection, so you get the most out of your recording
• Can be used with your computer software
• With computer setup, multiplexers allow for remote access
• Can be used with either color or black and white cameras
• Connecting two VCRs allows for simultaneous playback and recording
Multiplexers are available in simplex or duplex models. Simplex multiplexers show a full-screen image of one camera while continuing to record, while duplex multiplexers give you split screen options for your cameras (when recording) so your monitor can show you several viewing areas at once. Duplex models are ideal for closed circuit television systems. 
10. IP camera

The demand of IP cameras is growing quickly in today’s surveillance market. Utilizing the Ethernet and TCP/IP standards, IP cameras can be connected directly into Internet. The cameras operate independently; have their own IP address, a built-in web server and can be placed wherever there is an IP network connection. IP cameras provide users with much more functionality and greater cost savings compared to CCTV security systems. CCTV systems require installing coaxial cable from each camera to a dedicated monitor at a fixed location. IP cameras can share an Internet line making them much easier and cheaper to install. Plus for an IP camera, you will not need to purchase dedicated equipment to manage your security system, because the images can be monitored from any PC anywhere in the world.

Our IP Cameras enable a quick an easy connection to the internet to allow you to monitor your most precious asset such as you home or business. Whether it is night or day good weather or bad, you will get the view you desire. IP Surveillance Systems digitize video streams at each camera on the network this digital stream is then transferred over a standard wired or wireless Internet Protocol (IP) network. Unlike traditional analog closed circuit television systems that transport analog signals back to a centralized video recording device, IP surveillance systems digitize and compress the video at each camera and send a digital signal across a common IP or Ethernet network. IP Surveillance employs a decentralized data encoding system that sends binary data across a shared, standards-based IP network – the same one used for email, Web pages, file transfers, and other data network applications.  

11. Motion detectors
Wireless motion detector/sensor alarm system detects and reports human motion inside a home or office. It can also be installed under an eave or awning outside for light-duty outdoor applications. This wonderful wireless motion detector is ideal for those wanting protection inside their homes, business entrances, garages, and/or barns.

Motion Detector Features:

The wireless motion sensor system includes one passive infrared motion sensor and one receiver but additional infrared motion sensors and receivers can be added. The system is compatible with portable receivers and driveway alarm sensors including the outdoor infrared motion sensor, buried driveway probe sensor, as well as our driveway hose sensor.

Easy to use and install- sets up in minutes. The motion sensor has an 80-ft detection range and can transmit a signal to the receiver up to 3000 feet away. The passive infrared sensor is able to monitor an area up to 100 degrees wide. With the integral mask, the detection area can be narrowed down to 20 degrees or anywhere in between. With the swivel mount, the wireless sensor can be adjusted right/left up to 80 degrees and up/down up to 50 degrees. Motion detector detects humans but ignores small animals. With three different sensitivity settings, the sensor can detect a person up to 12 feet, 25 feet or 40 feet away. Does NOT require a direct line of sight between the motion detector and receiver. The sensor can be set to flash an LED or stay dark when a signal is sent. Receiver features sound and volume control (one of four user-specified tones: classical, Westminster chime, ding dong, or whistle) and has an output to trigger external alarms or bells. Sensor operates on 1 "9V" battery. Receiver plugs into the wall. Microprocessor code-learning technology eliminates false alarms, receiver responds only to motion sensors assigned to it. One motion sensor can communicate with multiple receivers in larger installations.

13. Infrared cameras
You need video surveillance. But you need it at night, in low light areas, and you’re afraid of investing in a product that will not give you the returns you desire. The answer to this problem is an infrared camera. An infrared camera is an ideal product for anyone needs to capture images in the dark for work or pleasure.

An infrared camera uses infrared light instead of the regular lighting spectrum in order to produce better images in complete darkness or low light conditions. Night vision cameras only record in black and white, but some will record color during the day.
IR cameras features infrared cameras and thermal imagers for a wide variety of applications. We offer systems for predictive maintenance, building inspection and energy conservation, research & development, process monitoring and security/surveillance requirements.

Long wave infrared cameras are used for many applications, including predictive maintenance, electrical inspections, building inspections, energy conservation, research & development and security/surveillance. Uncooled infrared cameras provide affordable solutions for many infrared inspection requirements, while cooled LWIR infrared systems provide high performance for demanding scientific infrared imaging requirements
