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.

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.

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.

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

We upgraded from a Defender system that was several years old. This 4K system is awesome. The pictures are very clear, even at night. I also like that the color comes on when the light is activated. The system is easy to use and search and playback are also easy to use. I also like the advantage of having sound available which we did not have before. I highly recommend this system.

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.

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 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.

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.

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.
