Excellent Security Camera System

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.

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.

Happy with product

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.

Cameras are easy to set up and great features.

Love the features and the ease of the cameras and setup. I do wish the video was a little clearer at 30 feet off the road and was hoping I would be able to catch a license plate number. I do like the fact that the cameras work just on a twisted pair of cat5 cable.

Hello Hank, Thank you for your wonderful review. Proud to hear that you love how easy the cameras are to set up. License plates can be more challenging to capture on video depending on the speed of the vehicle and the angle of the cameras, as well as the distance from the camera. Thank you for choosing Defender to protect what matters most. Best Regards, Amanda M | Defender Customer Experience Supervisor

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.

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.

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 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.

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.

Great Cameras BUT Fatal Flaw in Empower Phone App

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.
