As humans we see life through one pair of lenses, our eyes. Because of that we think of every memory as a one shot movie where the action is always in front center. For most of our electronics that mentality works well. Digital cameras and camcorders are held in front of our faces to capture the scenery through our point of view. We cannot do that with CCTV cameras. While there are cameras that can Pan, Tilt, and Zoom at a controller’s request, most surveillance cameras are still and focused on one area. Many times people want just a single camera to tell the entire story of an incident. Multi-camera surveillance is the only way to capture the whole story.
Single Camera Surveillance – Corner
Imagine a store is robbed. One camera is placed in the corner to view the entire store. It may capture the actions of the robber, but it will not have enough resolution to get a positive ID. It may show that the person was wearing a red shirt and a hat, but so will the eye witness statement from the cashier. It will do nothing to help find and prosecute a criminal.
Single Camera Surveillance – Front Door
Now we take the same camera and we position it to have a tight shot around the front door in order to get better facial picture for the police. If the same robbery took place the surveillance camera would not see the action like multiple cameras would, but it would get a good picture to help identify the robber. In that case the police would have the statement from the witness and a usable picture. So what’s the point?
Multi Camera Surveillance
Use multiple cameras to tell one story. I will use the same example. A robber walks in and a camera gets a tight shot of his face. Switch to camera two which will show the action of the event. Then to camera three that is outside to show the robber running to the car. Lastly turn to camera four showing a different angle of the car and where it was going. Alone these clips are weak, but together they tell the story of an event and give details that a single camera never could.
