Security Camera Tips: Apply Logic when picking cameras and lenses

Consider the following when choosing a CCTV surveillance camera:

Sketch out a Floor Plan:
Put in all camera locations.
Consider the distance to your surveillance zone:Are you 5 feet or 15 feet away from your surveillance target area? It is best to locate your camera as close to the surveillance area first, then choose how much zoom you need. Do you need 4mm, 8mm or 12mm lens?

2. Field of view or area of surveillance: Take photos of areas you want to cover from the proposed camera locations.
What lens you need depends what you want to see and how far away and how wide a viewing area. Wide angle and fisheye lenses are available.
3. Resolution:
Do you want to capture a persons face or a car license plate? Each camera location will determine which lenses would maximize your surveillance potential. Do you need
50mm lens or standard 8mm?

4 .Vandalism potential: Will your camera be subject to damage? Damage resistant cameras are available.

Lighting: Is the space well lit or dimly lit. Are the lights turned off at night? Do you want to monitor the area with the lights turned off? Do you need infrared or low light cameras?

6. Budget:
Just like any technology, the more you spend, the better the system you get. Keep in mind a low cost camera is better than no camera.
