Install and set up was easy. Running wires in the attic is a challenge but would be for any brand. Recommend that you test all equipment and then pull wires and mount cameras. Note for possible improvement would be to use a better quality adjustment screws. They strip out very easily. Suggest using a high quality torx head screw. Had a problem with a couple of the cameras going offline, not sure why. I rebooted the NVR and they all reconnected. I had Lorex cameras for many years and I believe these are better quality and set up was much easier.

SO FAR EVERYTHING IS WORKING GREAT! NO ISSUES! SO NICE TO HAVE EYES ON ALL OF MY PROPERTY!!

Works great would recommend 👌 thus product to anyone.

Really good support when I call in. The Sentinel system is working well and easy to install.

Just what we needed, and works as advertised. Easy or installation and good quality

Very nice product at a great price, video quality is excellent.

Excellent product!! The wiring is easy to work with and the metal construction is fantastic!!

Camera system was easy to set up, program, and utilize. Provided added security with good HD video recordables.

This is an easy install and works better than other IP security cameras. It would be nice to have the Defender cameras to work with Amazon Alexa, Google Home for smart home features which other camera vendors have it.

Fantastic security system for monitoring our manufacturing facility. Installation was easy and the cameras have a simple, yet robust UI. Would recommend to anyone looking for a simple yet effective security system.
