Great product with big wires....

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.

Defender Cameras Canada

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.

Great system

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.

Happy with product

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.

Exactly What I Wanted From A Video Security System

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 but....

Love it but.... The set up was simple. The quality so far, so good. The human detection is meh. It keeps telling me every 15 minutes the same tree is a human. Or the bucket in my yard is a human. Trying to figure out the human setting. I wish the scheduling was easier too. Not intuitive. I hope I can figure it out. Follow the YouTube on how to share access. It's wonky. But it works if you follow the video's guidance.

Mostly good system. Pretty happy.

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.

Hello Annie, Thank you for your review. Please note that human detection significantly reduces false alarms that can be triggered by insects, rain, swaying trees, passing vehicles, or animals.  Please note some false alerts may occur as the algorithm is designed to reduce these but will not eliminate them completely. Thank you for choosing Defender to protect what matters most. Best Regards, Amanda M | Defender Customer Experience Expert

Quality Cameras, Quality Support, Questionable DVR

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.

Third System - Best Yet

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.
