With the on-camera technology of analyzing person and vehicle shapes, this camera offers accurate detections, and thus greatly reduce the false alarms on trivial objects’ movements. Built-in mic & speaker allow you to listen and talk back to whoever the camera catches in real time: A “Hello!” to friends or a “Get away!” to the unwelcome. You can monitor large areas with a single security camera. Its 2K 4MP high definition provides you with a clearer visual quality & smoother live viewing experience. The camera with infrared LEDs provides superior image quality for your nighttime recordings. It is ideal for outdoor areas that aren’t always well-lit. This battery camera supports both 2.4 GHz and 5 GHz (5.8 GHz) frequencies to ensure better performance for camera networking.
