Anywhere! Literally - not only as a security measure but can be used to monitor staff protection, staff management, shrinkage and criminal damage, process monitoring, really a wide application.

This is normally a personal issue however overt (visual) cameras are more popular especially as they not only record but act as a deterrent also. Covert (hidden) are used for delicate situations whereby you have ongoing problems that cannot be dealt with during conventional business conduct. Both types of systems are extremely effective.

Another personal issue - although there are some guidelines to be adhered to: Color does not work well in dark conditions unless you have superb lighting or use of Digital Cameras. Infra Red will not work with Color Cameras. Black and White Cameras are normally a higher specification and offer a far crisper picture. Black and White will work well at night with the aid of Infra Red or normal Halogen Lighting.

Great question - how long is a piece of string? There is a calculation for this.
a. There are many factors involved in choosing a suitable lens, as the lens size increases the left to right field-of-view narrows and the distance increases.
A variable focus 1.8mm ~ 3.6mm lens is ideal for monitoring hallways, doorways, and average size rooms

A 5.0mm ~ 40mm lens has the ability to be used for monitoring hallways and doorways and can be easily adjusted to monitor long driveways or areas several hundred feet away.

Beware of many online lens calculators which produce inaccurate angle measures for these focal lengths. Also, most 1/4" CCD cameras produce a significantly narrower field of view with the same focal length lens. Due to the physical nature of lens optics, the numbers listed below should be considered accurate to within ± 3° and therefore a few feet / meters as well. They are intended as approximate guidelines to help select the appropriate lens, while each camera in fact has its own unique field of view with each specific lens. In addition, C- and CS-mount lenses typically deliver a slightly narrower field of view than our comparable board lenses.

Lenses wider than roughly 5mm produce "artificially" wider fields of view than more telephoto lenses. In order to do so, the video image is slightly curved at the edges of the screen. While this artificial distortion is nominal for focal lengths between 4.3 and 3.6mm, curvature increases with wider angle lenses.
Each size lens is available with a manual or auto-iris lens.

The manual-iris lens is more affordable but should only be used in indoor applications where the light source remains constant The auto-iris lens can be used for indoor areas with varying light conditions as well as outdoor installations.

DVR or Digital Video Recording is a PC based system or embedded system that records your CCTV images digitally rather than on a VHS tape. This DVR system will replace your Monitor, your Multiplexer and your VCR and the camera images are stored on the hard disc on the PC.

Data backup devices include CD-RWs, DVD-RAMs, DVD-RWs, DATs, etc., any device that Windows recognizes as a drive, and you can also backup on a network drive.

The data is only be viewed through the supplied Backup viewer. Data backup is also possible on the Search program, where it can be saved in AVI format, making it conveniently viewable through the Windows Media Player(by enabling "View- Caption" from the menu, you can also conform information data

NFPA 72 is a prescriptive standard that applies to Fire Alarm Systems. While the NFPA 72 standard makes no mention of gas detection, many clients are applying NFPA 72 standards and requirements to both fire and gas detection systems. There are several advantages to NFPA 72 certified systems that include:

• Allows for the combining of both fire alarm and gas detection functions into a single safety system
• Ensures that local "authorities having jurisdiction" like fire marshals or fire authorities have assurance that the system complies with the applicable codes and standards 
• Allows the end-user to lower their insurance costs because they are using a certified system
•  A NFPA 72 certified solution ensures that you are complying with the best practices in the industry as drafted by the NFPA

General Monitors' HazardWatch offers a flexible fire and gas detection platform which is FM certified to comply with the NFPA 72 standards and requirements.

The choice between a PLC and Controller-based system is primarily driven by the size of the application.

PLCs are best suited for medium to large size gas detection systems (25+ points of gas detection). For very large systems, PLCs have the advantage of scaling fairly inexpensively to accommodate large point counts. PLCs offer the added benefit of extensive connectivity options for communicating with other DCS or ESD systems.

Controller-based gas detection lends itself to small to medium sized systems very effectively. A controller-based gas detection system is relatively easy to implement, and does not require software programming tools. The hardwired nature of a controller-based solution makes it inherently simple to troubleshoot and support.

General Monitors has the most complete line of gas and flame controllers in the industry. We offer multiple channel gas controllers like the 610A and DC110, or single point gas controllers in our 02A series with MODBUS communication.

Addressable fire alarm communication devices can be used in process areas when the operating specifications of the devices are compatible with the electrical and environmental conditions found in these process areas.

Most commercial addressable fire alarm equipment are normally rated for operation in general purpose environments with ambient temperatures between 0 and 50°C. Most process area environments have operating temperature ranges outside the 0-50°C range. Many process area environments require devices suitable for Division 1 or Division 2 areas.

When using commercial addressable fire alarm equipment we normally recommend that the addressable equipment be located only in environmentally controlled areas such as crew quarters, control rooms, office areas. If devices to be connected to the addressable fire alarm system are to be located outside these environmentally controlled areas, we recommend the use of an addressable to conventional circuit converter to be installed inside the environmentally controlled area with a conventional circuit interface to the process area located device.

Building management system {BMS} is one of the important components in constructing a green building. It ensures taht the building remains 'green', through its life. 

BMS is basically a solution which is put into a facility toensure an environment that is safe, secure, comfortable and energy efficient.When properly integrated into a facility, BMS can result in the following benefits:Optimize energy consumption,Provide alarm systems so as to take corrective actions,Monitor and control indoor comfort condition.

A BMS minimizes energy consumption & maximises indoor comfort, making it a valuable tool for any sustainable design.

Benefits of BMS: Operational energy saving to the extent of 15 – 20%; Maintenance of comfort conditions; Enhances indoor air quality; Provides critical alarms and remedial actions.
