The camera 530 may be triggered by several different types of techniques. For instance, a Passive Infra-Red (PIR) motion sensor may be built into the camera 530 and used to trigger the camera 530 to capture one or more images when motion is detected. The camera 530 also may include a microwave motion sensor built into the camera and used to trigger the camera 530 to capture one or more images when motion is detected. The camera 530 may have a “normally open” or “normally closed” digital input that can trigger capture of one or more images when external sensors (e.g., the sensors 520, PIR, door/window, etc.) detect motion or other events. In some implementations, the camera 530 receives a command to capture an image when external devices detect motion or another potential alarm event. The camera 530 may receive the command from the controller 512 or directly from one of the sensors 520.
In some examples, the camera 530 triggers integrated or external illuminators (e.g., Infra-Red, Z-wave controlled “white” lights, lights controlled by the module 522, etc.) to improve image quality when the scene is dark. An integrated or separate light sensor may be used to determine if illumination is desired and may result in increased image quality.
