Excellent Security Camera System to protect your home. I have been a long time Defender systems user and love them. These model specifically has wide angle cameras and great night vision capabilities. the sensors work great and picks up movements immediately. If you are using for inside the home, i would recommend to turn off the lights for night vision. Access from app works nice and very quick/easy to setup. Audio feed, although works only from one camera at a time, is a good feature to have.

System was pretty easy to install and works well. Like having a powered system. Package was complete which was nice. Wish you had better quality screws or perhaps change to hex screws for camera angle setting. Found that the current phillips screws are soft and strip pretty easily.

Love the features and the ease of the cameras and setup. I do wish the video was a little clearer at 30 feet off the road and was hoping I would be able to catch a license plate number. I do like the fact that the cameras work just on a twisted pair of cat5 cable.

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.

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.

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.

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 a great camera system for the money. I actually bought the 4 camera system first and then realized that I needed more cameras to cover our large property. My advice is to buy a system with a box that can handle more cameras than you think you need right now. That way you can add cameras in the future without having to replace the main unit. Picture quality is very good. multi view, notifications, and incident search all work great. The only small issue is that it pauses frequently during playback for a few seconds each time. Other than that, this system rocks.

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

After a lot of research I chose to install the Defender Sentinal system. I was excited to buy from a Canadian company. This system checked all my boxes including non of the gimmicky features like flashing lights and sirens. Overall quality seems to be what it should be for the price. Installation is only as difficult if you want it. Set up was relatively simple. Picture quality is great in daytime and acceptable at night using the IR feature. The layout of the NVR systems OS could be refined but overall it works. Improvments in the app would be beneficial but again it does its job. I installed this system about a month ago and would definitely buy again.
