Pelco’s video analytics technology for effective security

Security camera systems don't have human intelligence - but intelligent video analytics are the next best thing. Few new technologies have excited the imagination of video security professionals like video analytics. Through constant automated digital screening and filtering, video analytics can identify specific conditions and notify operators of potential issues, allowing security officials to make quick, informed decisions.

"The greatest value that I see in our analytics has to do with the ability to use digital software to achieve a solution that normally would require physical hardware to get the same result," says Sara Scroggins, Pelco by Schneider Electric Product Marketing Manager. "For example, using a simple digital line versus a tripwire to create an alarm when someone opens or closes a door is a significant cost savings compared to hardwiring a door with a contact closure."

Pelco engineers have developed numerous video analytics features to track various behaviours - from recognising an abandoned briefcase or duffel bag to determining when someone is loitering in a specified zone.

Using a mathematical model to recognise the background of a scene, the system establishes the baseline for the background and can then recognise pixel differences as objects "on top of" or "in front of" the background. Once a foreground object is detected, the system begins to recognise features: size, color and movement. These characteristics are used to track objects and recognise abnormalities to notify security personnel.

"Ultimately, video analytics can help our customers save money and operate more efficiently," Scroggins says. "Think of it in terms of operating expenses and bringing more value to your business by using object counting to see how many people are coming in to a retail establishment at certain times of day. A business can then better determine how many employees need to be staffed at those times and in what areas they're most productive."

Pelco analytics packages are included with Spectra HD pan/tilt/zoom cameras, Sarix fixed cameras and NET5400 Series encoders at no extra charge. Pelco analytics work with the Pelco Endura system.
