What is Video Analytics in Security Cameras?
Video analytics in security cameras is a big leap forward from motion detection. Motion detection looks for pixel change, whereas video analytics uses intelligence to identify people, vehicles, and other objects. This is done to make video surveillance more efficient, cost-effective and less prone to human error.
Video analytics can be used in real-time to identify a security breach or can be used to analyze pre-recorded video footage to identify patterns, trends or specific incidents.
The video can be sorted by time and date or by specific events such as people or vehicle detection.
Make searching through video easier
Searching through recorded footage using video analytics in security cameras is a breeze compared to motion detection. On a rainy night, motion detection will pick up hundreds of false alarms, whereas video analytics will reduce false detection by upto 90%.
A video search takes minutes when using video analytics compared to likely giving up if searching with motion detection.
One of the simplest applications of video analytics is detection on a fixed background. For example, someone climbing over a fence and into a construction site or yard. It will be inefficient for a security officer to watch the cameras all night to monitor for someone crossing the perimeter.
However, with video analytics, the camera detects a person or vehicle in a specified area, and can trigger an alert. This results in getting a security officer’s attention, who can intervene before the intruder causes any damage.
Get alerted to a problem, before it’s a problem
Another common application of video analytics is triggering alerts in real-time, as an incident occurs. Let’s say your facility has a large parking lot where you are having vandalism or garbage dumping problems. You know the problem occurs after hours when there is no one around. You can set up an alert to be triggered if a car stops there for more than 5 seconds between 9PM-7AM.
