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.

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.

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

Discovering small details..

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

Quality system, easy to set up!

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.

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.

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 value quality cameras but Settings limited.

Good quality camera, easy to install. Design needs more flexibility to position anywhere and see image upright. Also gets a lot of false positive “human detection” even though we turned sensitivity to Low.

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.
