I love the new 4k system I just purchased. The digital zoom is wonderful and the picture is crystal clear. The adjustment on the cameras are not what I was hoping they would be, but with a little time I was able to point all the cameras where i needed them.

I bought this system to replace an older different system that stopped working, so i didn't have to run wires this time. All the wire connections were the same from the older system to the new Defender system. I am very impressed with how easy the setup was, even setting up the app on my phone was very easy and stupid proof. The last system I was only able to live view from my phone but this system I can rewind to see what happened the other day. Hands down this is a well worth system. "Love It"

Camera system is a very good system. The only issue I personally have is the DVR fan is a little loud for me. My old system was in my living room so I did not want to move all the wires for my new Defender system. The app could be a little better. I have to open twice to get the cameras to refresh.

Easy install. Booklet and online videos walk through process without anything missed. Picture quality amazing. Wired means never having to recharge batteries or lose signal. App on iPhone and iPad is terrific. Very happy that I chose the Defender system.

Purchased this system to keep an eye on our camp. Install of cameras and wire routing was fairly straight forward, you will quickly identify if you have grabbed the wrong end of the cable for the camera. We installed all 4 cameras connected them to the DVR and plugged in the power, it was very rewarding to have the setup screen flash on with images from the 4 working cameras in the background. Set up of the software was okay following the provided instructions, getting the app set up for remote viewing from the phone was a fairly simple process with a QR code. After that, your on your own, and much of it is not that intuitive, but there is plenty of Youtube videos and other forums for operating the system. The cameras are decent quality and the DVR seems solid enough. But time will tell.

The new 4K system is much easier than the older systems. For the DVR, it was basically plug it into the power and the router. Then plugging in the cameras. I has previous camera wiring for an older system and have used it for the new 4K along with the old cameras. I plan to run the newer camera wires to replace the older one along with the new cameras. I'll change them one-by-one as time permits.

Previously had 964H cameras from another company. Read most reviews and decided to try this system, as I had already had the BNC cables run throughout my home. The resolution blows my old system out of the water. Would definitely recommend as the quality with price point is definitely a great value.

Faster than expected delivery, set up was simple, presale questions were readily answered and more importantly correctly answered. App works well. The system might be improved if computer could access dvr directly rather than having the intermediate step of downloading to a flash drive and then uploading to the computer, but this hopefully would be rarely used.

I just bought this item and I'm very please with the easy setup and connections.

I purchased the Defender 4K UltraHD 3TB six camera system to replace an Old Defender System. I was amazed at the much better pictures. We are proud of the new system .
