Incorporating a powerful digital signal processor (DSP) dedicated to the video content analysis, it features three reliable and helpful detections including tampering detection, moving object detection, and loitering detection. With the tampering detection, it is capable of detecting incidents such as shooting redirection, blocking or defocusing of cameras, or even spray-painted. For motion detection function, it is capable of distinguishing between creature's motions and still backgrounds or natural movements like swaying trees, waves or sunset so as to prevent the false alarms from environmental noise. Additionally, a suspicious object in the predefined area (window) will trigger alarms once the dwelling time of the object is longer than the given time. By embedding the video content analysis into the network camera rather instead of back-end software platform, IP7251 greatly reduces the server workload, network bandwidth, and storage requirement.

IP7251 is achieved with a powerful combination of great features: a Sony progressive scan CCD sensor, a removable IR-cut filter, simultaneous dual streams, PoE compliant with 802.3af, 3GPP mobile surveillance, two-way audio by SIP protocol, and digital I/O. With the intelligent detection function, VIVOTEK IP7251 can effectively prevents unwanted noise components from accidentally triggering an alarm, providing a more reliable detection method, thus reducing the number of false alarms.
