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 camera system for the price

This is a great camera system for the money. I actually bought the 4 camera system first and then realized that I needed more cameras to cover our large property. My advice is to buy a system with a box that can handle more cameras than you think you need right now. That way you can add cameras in the future without having to replace the main unit. Picture quality is very good. multi view, notifications, and incident search all work great. The only small issue is that it pauses frequently during playback for a few seconds each time. Other than that, this system rocks.

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.

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.

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.

Sentinel 4K

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, will update w/ further exploration

Amazing picture quality though no imagery at night. Playback feature could be better continues to freeze and lag on the fastest internet connection possible.I would prefer more ease of setup and description of features.

Smart home features are missing

This is an easy install and works better than other IP security cameras. It would be nice to have the Defender cameras to work with Amazon Alexa, Google Home for smart home features which other camera vendors have it.

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.
