Product quality is good. The only design flaw is the connector is too big to feed through the metal screw tube, you will need to do that in order to feed the camera through the pre-drilled hole on the door. I end up cutting a slit on the metal tubing to push the cable out so that the whole connector can come out. Hope the next version the connector is small enough to push through the metal tube. Otherwise, all fine.
The product arrived in very good conditions. The quality of the product is good. Network IP Camera has been connected to POE on an NVR and operates in parameters, as specified on the site. I recommend!
