I’ve created a custom integration for certain Tigersecu DVRs. It creates streaming camera entities, motion and video loss binary sensors, and various health and status sensors for the DVR itself. It takes advantage of the websocket event stream from the web interface on my 16-channel Nova Super HD model. It expect it would also work on the 4-channel model, and I’m curious if it will work on the H.264 Super HD models.
I very highly doubt it will work on the Tuya-based models.
