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.

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.

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.

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 Sentinal 4ch POE

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.

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

Nice system

The camera install was the hardest part for me. So far the system works great. I like all the features it has and have just started to connect it to the internet.

installed at lake house

Enjoying the customisations available. Much to learn. Fairly user friendly with a bit of exploration. Human detection feature is a bit of a challenge yet.

just an avearge..

I did not know that it will need a screen to do all the configuration and settings. that is a drawback. Clarity of picture is not as per my expectations. It can't read the number on my car's number plate parked just in front of my driveway.

Hello Rohit, Thank you for your honest review. The system can be monitored from the app, to set the system and for several configuration options, you will want to connect the NVR to a monitor or TV. Please reach out to our support team, we would be happy to assist you with checking your settings to ensure you get true 4K picture quality.

Great system, quality video

Super easy to install, and love the crisp picture. Only quip I had is that 60’ runs are tight when going to opposite ends of the house, 80’ cable runs would have been much better as I had to extend 2 of my camera runs.
