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.

Quality system, easy to set up!

Love having a secure home December 17, 2023

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.

Can't connect to a real person

CDA Steve December 13, 2025

Bought a four camera eight port system, thinking I could add extra cameras later, Cant buy extra cameras. Defender lost a customer. I'll be upgrading with a different company that will sell extra cameras.

Great Cameras BUT Fatal Flaw in Empower Phone App

KenAndLora January 23, 2024

The Defender Sentinel cameras themselves are great but the Empower App that you use to monitor them has a fatal flaw. Unless you are satisfied with scrolling through and then viewing countless alarm thumbnails, you are unable to see a graphical timeline with alarm triggers LIKE ALL OTHER SYSTEMS (see image for comparison). All you can see is that the camera was recording at a given time.

Happy with product

BigD August 25, 2023

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.

Great product with big wires....

Anonymous May 12, 2024

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.

installed at lake house

The Don February 26, 2024

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..

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.

Good but....

PKUD May 28, 2024

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.
