I've been doing some more troubleshooting and found that it's somehow related to the Post Jpeg Quality setting. High quality snapshots with 4MP and 8MP cameras seems to be the cause. The snapshots are captured, but causes BI to crash. I have it running as a Service configured to restart on its own, so it recovers fine, but when it restarts it tends to lose contact with the wireless RCA video doorbell for a while, which is not fine.
The higher the Jpeg Snapshot quality, the faster BI crashes. At 100%, BI will crash 2 - 3 times per minute. Dropping the snapshot quality to 33% extends BI's time to crash to several minutes. This was tested with Record snapshot enabled on a single 4MP camera (Loryta
IPC-T5442TM-AS). Changing the camera settings to a lower quality feed (low bit rate, Good vs Best, etc) also helps, but that defeats the purpose of using a high MP camera. Seems to work fine with 2MP cameras though, or maybe I didn't wait long enough for a crash.
Still working on the issue with Ken...
