Fixed Network Camera
P/N:011001501 Ver 1.1
IP7251, the newest addition to VIVOTEK’s progressive-scan product lineup, features video content analysis that can
analyze video images immediately without the need for additional software. The three types of intelligent detection
provide an improved ability to monitor tasks, freeing an operator from constant supervision of a camera.
Incorporating a powerful DSP (Digital Signal Processor) dedicated to performing video content analysis, the IP7251
features three reliable and powerful detection modes: tampering detection, moving object detection, and loitering
detection. With tampering detection, the IP7251 is capable of detecting incidents such as shooting redirection, blocking or
defocusing of cameras, or even spray-paint incidents. For the motion detection function, the IP7251 is able to distinguish
between an object’s motions and still backgrounds or natural movements such as swaying trees, waves, or sunsets so as
to prevent false alarms due to environmental noise. By enabling the loitering detection function, an alarm will be triggered
once the loitering time of a suspicious object in the predefined area (window) is longer than the preset target.
Instead of using a back-end software platform, the integration of video content analysis in the network camera itself
greatly reduces server workload, network bandwidth consumption, and storage requirements. By installing the IP7251
and its intelligent detection functions, the user can effectively prevent unwanted noise from accidentally triggering an
alarm, providing a more reliable surveillance solution.
