Review on ANNKE H800 4K PoE Security Camera System with Audio Recording, Ultra HD 8MP IP Cameras, Smart IR, Sony Sensor, and 2TB HDD by James Turpin

Update 10/01/19 There was some delay during playback. It turned out to be a doorbell camera. The doorbell camera is similar to the ring. When connected to the NVR, it slows down the playback of the recorded video. Disabling returns playback to normal. This may be because the NVR is limited to 15 fps and my doorbell camera is limited to 22 fps. Had to disable the doorbell camera which was very disappointing. Everything else is fine. Easy hardware setup. Just connect everything as shown in the diagram. Motion detection is reliable. I walked around him to make sure he could see me in his full field of view. Dislikes: A small screw that secures the camera (only applies to my model, see picture). Should be 2-3 screws. That's safe enough, but if that screw is removed, what then? Of course, it does not have to be constantly dismantled. Will update if this is an issue. I bought this additional camera, the installation was plug and play. Connect a Nelly's doorbell camera. Unfortunately, the motion detection does not record on the NVR. I have to rely on the doorbell's camera app to record traffic and get updates on visitors. The NVR can only communicate by recording on a preset schedule or continuously. A little disappointing.
