If you experience your LILIN HD PTZ showing video loss every few seconds when installed on a LILIN NVR touch, please update the firmware on the NVR Touch to firmware version 1.0.48 #2399 or above. The latest version of NVR Touch firmware and an installation guide are available here.
The issue is caused by an older firmware on the NVR Touch, in most cases the firmware loaded on the NVR was released before the HD PTZ series camera's were available to purchase. A firmware update is required to add additional support for these new style camera's.
