Next CAM PG2 is a two-way, wireless photo detector that provides the perfect solution for visual alarm verification, day or night. This detector is typically installed in areas where extra visibility is needed, such as hallways and stairways. When the alarm system is armed and the PIR sensor detects movement, the detector sends an alert to the control panel and activates the camera. The control panel immediately begins sending images of the premises to the central monitoring station. By reviewing the images in real time, security staff can verify the alarm and respond accordingly.
