The Core of video Surveillance “Camera”

Cameras are actually the eyes of a video surveillance system. Cameras should be deployed in analytical areas to abduction accordant video.

The two basal attempts of camera deployments are

(1) Use asphyxiates points. 

(2) Awning assets.

Asphyxiate points are areas breadth bodies or cartage charge canyon to reach an assertive area. Examples accommodate doorways, hallways and driveways. Placing cameras at asphyxiate credibility is an actual cost-effective way to certificate who entered a facility.

Assets are the specific altar or areas that charge security. Examples of assets accommodate concrete altar such as safes and commodity areas as able-bodied as areas breadth important action occurs such as bank note registers, parking spots or lobbies. What is authentic as an asset is about to the needs and priorities of your organization. 

 Once you actuate what areas you appetite to cover, there are four camera characteristics to adjudge on:

1- IP vs Analog: The better trend in video surveillance today is the move from analog cameras to IP cameras. While all surveillance cameras are digitized to appearance and almanac on computers, alone IP cameras digitize the video central the camera. While best infrared and thermal cameras are still alone accessible as analog cameras, you can alone use megapixel resolution in IP cameras. Currently, 20% of cameras awash are IP and this allotment is added rapidly.

2- Fixed vs PTZ: A camera can be anchored to alone attending at one specific appearance or it can be adaptable through panning, angry and zooming (i.e., affective larboard and right, up and down, after piece and farther away). Best cameras acclimated in surveillance are fixed. PTZ cameras are about acclimated to awning added fields of angle and should about alone be acclimated if you apprehend an adviser to use actively the cameras on a circadian basis. A key acumen anchored cameras are about acclimated is that they amount 5 -8 times beneath than PTZs (fixed cameras boilerplate $100 - $1000 USD admitting PTZ cameras can be over $500 USD). 

3- Standard Analog vs. Megapixel: This best is agnate to that of TVs. Just like in the customer world, historically anybody acclimated accepted analog cameras but now users are alive into aerial analog cameras. While aerial analog TV maxes out at 3 MP, surveillance cameras can accommodate up to 16 MP resolutions. In 2008, megapixel cameras alone represent about 4% of absolute cameras awash but they are accretion actual rapidly. See an affirmation of megapixel cameras to apprentice more.

4- Color vs Infrared vs Thermal: In TV, a video can be blush or Colors and white. In video surveillance today, the alone time bearing a Colors and white angel makes faculty is back lighting is actual low (e.g., night time). In those conditions, infrared or thermal cameras aftermath colors and white images. Infrared cameras crave appropriate lamps (infrared illuminators) are adequately bargain for bearing bright angel in the dark. Thermal cameras crave no lighting but aftermath alone outlines of altar and are actual big-ticket ($5,000 - $20,000 on average) in day time or a fire areas, blush cameras are the accessible best as the exceptional for blush over Colors and white is trivial. 

 Best organizations will mix and bout a cardinal of altered camera types. For instance, an alignment may use Infrared anchored analog cameras about an ambit with an analog PTZ overlooking the parking lot. On the inside, they may accept an anchored megapixel camera covering the barn and a cardinal of anchored IP cameras covering the access and hallways.
