Video Content Analytics Smart Detection

If you think that DVR-based security systems mean having to sit through hours and hours of video to search for a few minutes of evidence, think again! G&A Surveillance Nigeria’s Smart Search function prevents your organization from having to waste time or spreading your staff too thin just to look for a certain section. G&A Surveillance Nigeria’s Smart Search function helps you shorten investigation time with three special features: unique size filtering, advanced motion search, and missing and left object search.

Other than conventional DVR functions, G&A Surveillance Nigeria offers more powerful and intelligent features in video content analytics, such as smart search and object detection. G&A Surveillance Nigeria provides several different client programs, which includes the following: Remote Viewer, PDA, and Phones, which allows you to control, monitor and record surveillance video from a remote computer or with your handheld devices, like iPhone, Blackberry, Droid, and IPad.
