Cameras are the eyes of a video surveillance program. Cameras must be set up in critical regions to capture video.
Both primary fundamentals of camera installation are (1) utilize chokepoints and (2) cover resources.
Chokepoints are places where individuals or vehicles need to pass to enter into a particular place. Examples include doors, hallways, and drives. Putting cameras in chokepoints is a really cost-effective method to record that entered a center.
Assets will be the particular items or areas that require security. Examples of resources include physical items such as safes and product areas in addition to areas where significant activity happens like cash registers, parking areas or lobbies.

As Soon as You decide exactly what areas you would like to pay for, you will find 4 camera features to pick on:
1. Fixed vs PTZ: A camera may be corrected to just look at one special view or it may be movable through the use of panning, tilting and zooming (i.e., moving right and left, down and up, closer and further off). Most cameras used in surveillance have been mended.
PTZ cameras are usually utilized to cover wider areas of opinions and should typically be used only in the event that you anticipate a track to actively utilize the cameras on a daily basis.
2. UV vs Infrared vs Thermal: In TV, a movie could be color or black and white. In video surveillance now, the single time making a black and white picture makes sense is if the light is quite low (e.g., night). In these states, saline or infrared cameras create black and white pictures.
3. Standard Definition vs. Megapixel: This option is similar to that of TVs. The same as from the consumer planet, historically everybody employed standard definition cameras but today users are changing to high definition cameras. While high definition TV maxes out at 3 MP, surveillance cameras may offer up to 16 MP resolution.
