Hi,We have several 16 channel QVIS Pioneer Trio MK3 DVRs with all attached cameras on AHD 1080p over shotgun cable.I recently bought a couple of QVIS 5X-P400-VFG cameras to add on but, with the camera set to AHD, I can get no stream coming to the channel from the camera.It does work on analogue but we don't want that.I know the DVR port & cable works with another camera.Wondering if there's an incompatibility with the DVR and the 5MP cameras but I've been unable to find any information on this.Any help would be appreciated.Thanks
