Defender Cameras Canada

Thorn April 20, 2025

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.

Excellent Security Camera System

Shirish Patil August 9, 2025

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.

Great system, quality video

Anonymous May 25, 2025

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.

Sentinel 4K

Denis S January 19, 2025

Purchase 1 month ago, works as required. Quality very good. Easy to set up. Downside, I cannot add a software like I did with my Swann system to view my cameras on my home laptop : (

Good value quality cameras but Settings limited.

JDG1 September 24, 2024

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.

just an avearge..

Rohit July 17, 2022

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.
