Delivery was on time and nicely packaged.. I have not installed the units yet as I am still taking down my exciting security system, The only issue I would change is the massive weather guards that is on each camera input wire, when installing them on a wall or bulkhead you are forced to drill a 3/4" or larger hole just to get the wire through.. This is a major hole and takes a good sized drill leaving wall damage. The only option is having every camera using a junction box which is clumsy.

You changed your hookup technology, this new system can't be run in parallel with my previous Defender system. That's of little consequence, I'll run them side by side, but it wouldn't have been nice to have had a certain consistency. Regardless, I'm a kern patron of your technology, and will be buying more as my business grows.

We upgraded from a Defender system that was several years old. This 4K system is awesome. The pictures are very clear, even at night. I also like that the color comes on when the light is activated. The system is easy to use and search and playback are also easy to use. I also like the advantage of having sound available which we did not have before. I highly recommend this system.

After several weeks of research I decided to replace my old battery powered security cameras with Defender. I was tired of changing batteries and also wanted to have a system that used POE, 24/7 recording, 4K resolution and color night vision. When I received the system I connected everything and proceeded with the set up. System is very easy to set up right out of the box. Then came the challenging part of running wires in the attic and dropping them down the wall to my office where I set up the NVR and Monitor. After getting the wiring pulled the camera mounting was easy. Once done , I connected everything in my office and has been working great. One recommendation would be that the design engineers think about upgrading the adjustment screws to a torx head high quality screw. The phillips head screws are subject to stripping so just a suggestion. App works great and is easy to use.

The Sentinel 4K Bundle has all the features that I wanted in a video security system. No ongoing fees, no batteries to ever change, 4K video resolution, and simple to set up and operate. My total installed cost was about 20% of the cost of a similar "professionally" provided and installed system. I have already recommended it to a neighbour, who proceeded with his own purchase of a system.

They're excellent cameras you see good day or night excellent monitor I keep having troubles with cameras it's my second unit I had to buy your replace two cameras for me I bought another camera and another whole system Right now they're working fine excellent thank you

Good system. Easy to install. We enjoy the wide view. Can see a lot more than expected. Only issue is that we get alerts that they are picking up human body but when you look, it's nothing. We tried turning sensitivity down but it didn't help. So we get a lot of notifications for nothing. And it's the same spot over and over. Maybe it's a ghost? Lol otherwise we are happy with it all.

The system could have came with better quality Ethernet cables like cat 6. Also I would have loved to known that the nvr needs to be within 30ft from internet modem before I set all the cameras and wires up 95ft away from my internet modem. The last thing i don't care for is video playback is rather complicated. There is only pause and fast forward, no rewind to go back in case you want to watch something over again and you cannot zoom in on playback footage. The instruction manual is rather lacking in a lot of details. Very informative on setting it up with you phone, everything else isn't. However, the picture quality is absolutely amazing

This is actually an upgrade for me so I think I would appreciate this more, but I definitely love the wired cameras better. The quality in video is also a noticeable improvement and now that I can monitor from the DVR and not from the app, it’s more streamlined and not put together clunky to get the outcome I wanted which I now have. The quality of the cameras is also an improvement. You can feel how robust these cameras are compared to the previous wife ones I had. I did have one that had an issue with water intrusion which distorted the image, BUT I can tell this was a one off situation because these really are better in quality. So much that even with water inside the camera, distorting the image, it never shorted out and it still ran, so that also makes me think this is a one off situation. Also, Defender was quick and professional about making sure I got a replacement camera with ZERO headache. Lastly, the DVR seems a little flimsy and the software running on it is also very rough, but it’s in perfect working order. My only concern is “Time”. How will this DVR hold up by this time two years from now? Overall though, I think this is a great deal for the price point and would certainly recommend as a legacy customer.

This is my 3rd Defender camera system. By far my new system has better cameras, audio and even security motion lights. The system is priced lower than the original system I purchased over 12 years ago. My only complaint is the user interface which to me, is not intuitive. It takes real digging to find out how to replay and save videos.
