HD camera main features (overview)
You can use HD cameras to monitor and record the sights and sounds of the surrounding area. Built-in motion detection features allow cameras to record images automatically or send a notification to your mobile device when motion is detected. Additionally, built-in speakers and microphones allow you to talk to anyone who is near the camera.
HD cameras feature a built-in temperature sensor, which allows the camera to alert you when the ambient temperature is too high or too low, and a sound sensor, which allows the camera to alert you when sound is detected.
