VCApresence provides the very best in intruder detection

VCA presence: this suite will provide a very effective and easy to use intruder detection and tracking system. Base features include

1. Includes VCAsys tracker (see overview)
2. The Presence filter detects when an object such as a person or vehicle is inside or is crossing a zone or a line
3. Camera attack detection: detects moving, defocusing or covering of the camera. It does not respond to slow changes such as build-up of dirt on the camera lens or natural variations in daylight levels. (in next release)
4. Detection zones are polygonal with variable number of vertices so that any shape can be supported.
5. Detection zone can also be a line, which can have one or many segments
6. Includes non-detection zones for masking possible sources of false alarms
7. Fast moving objects are detected even if they pass through the zone or line quickly
