The camera 530 may be programmed with any combination of time/day schedules, system “arming state”, or other variables to determine whether images should be captured or not when triggers occur. The camera 530 may enter a low-power mode when not capturing images. In this case, the camera 530 may wake periodically to check for inbound messages from the controller 512. The camera 530 may be powered by internal, replaceable batteries if located remotely from the connected valve unit 510. The camera 530 may employ a small solar cell to recharge the battery when light is available. Alternatively, the camera 530 may be powered by the controller's 512 power supply if the camera 530 is co-located with the controller 512.
In some implementations, the camera 530 communicates directly with the monitoring application server 560 over the Internet. In these implementations, image data captured by the camera 530 does not pass through the connected valve unit 510 and the camera 530 receives commands related to operation from the monitoring application server 560.
