Features of alarm photo verification by MotionCam detectors

Updated December 20, 2019

The MotionCam motion detector uses two radio protocols simultaneously to communicate with the hub: Jeweller for alarm delivery and Wings for photo verification of alarms. In this article, we explain the settings that affect photo verification function, as well as the storing and transmission of photos in case of an alarm.

MotionCam activates its camera only in case of an alarm. The users (regardless of access rights), the security company or installer are not able to take photos by request.

What settings affect photo verification of alarms

After motion detection, MotionCam can take one shot, a series of 2 to 5 shots, or not use the camera at all.

The app displays a series of shots as looped animations, allowing you to evaluate what is happening at the premises in real-time:

MotionCam takes photos in three resolutions: 160 × 120, 320 × 240 or 640 × 480 pixels. The image quality improves as the resolution increases. However, high resolution increases the file size and the time of transferring from the detector to the hub.

You can choose how many MotionCam alarms are photo-verified: 1 to 10 or all of them. Disarming the system resets the alarm counter.

Triggerings that are beyond the set limit does not activate the detector camera, but the system still sends alarm notifications:

At default settings, MotionCam accompanies the first 10 alarms with a series of 3 shots in the resolution of 320 × 240 pixels. These are optimal settings for most premises.

How the MotionCam memory buffer operates

MotionCam uses an internal memory buffer to store the shots temporarily. The buffer erases after the successful transferring of shots to the hub.

Commonly, the buffer capacity and the throughput of the Wings radio protocol are enough to transfer all the camera shots to the hub. However, the maximum resolution used, communication noise, or weak signal strength, as well as numerous alarms, can lead to a situation where the detector does not have time to transmit all the shots taken to the hub, and the buffer gets full.
