Security Camera System

Just like the surveillance DVRs, Security Camera Systems also come in various models. In order to have a good, sturdy and reliable system, your planning must always start from a clear determination of the area that you propose to cover. The length, breadth and height are all determining factors and so is the situation: whether it is in-doors or outdoor. If it’s indoors, you do not necessarily need weather-proof cameras and/or heater-blower equipped housings for your cameras.

In most indoor situations, you may not even need 0 lux cameras, if there is any light available at night-time. The highly sensitive 0 lux cameras can take clear pictures in a pitch dark environment with the help of IR (Infra-red) sensors. Higher the number of IR sensors on your camera, better the picture quality you will get.

The length and breadth of the area desired to be covered helps you to determine what kind of a lens your CCTV camera be equipped with. There are wide angle lenses available that can cover a fairly large area, if installed properly.

In an ideal CCTV Camera System, you should have a combination of at least 2 different types of cameras. The entrance and exit doors are two of the most important points in any building, at least from the Security point of view. You need to use really high resolution, and if possible, True-Day and Night Cameras at these points. You must always keep in mind that criminals don't just barge into any property by choice. Most studies have shown that break and enters are pre-determined and the perpetrator/s case their target before-hand. In such a situation, there is always a possibility that they disconnect your power supply as well as the phone line before entering your premises. In case your Security Camera System is not capable of recording in zero light, all your efforts and expense, in installing the system, have gone waste.

The distance and angle of coverage are important considerations because all CCTV Security Cameras have pre-determined limits of what area they can cover. One thumb rule is: Wider the aperture, shorter the distance and smaller the aperture, longer the distance. However, this can change due to various other predominant factors like the quality of the lense and the weather resistance. All things being equal, if your outdoor CCTV camera has no protection against the elements, it will accumulate moisture at night and won't be able to take any pictures at all, never mind all other considerations.

The other part of the equation is the DVR. Please refer to the section: Surveillance DVRs and you will have a rough sketch of various components that you would require in order to successfully finish your project within budget.
