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.

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

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 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.

Defender Sentinal 4ch POE

After a lot of research I chose to install the Defender Sentinal system. I was excited to buy from a Canadian company. This system checked all my boxes including non of the gimmicky features like flashing lights and sirens. Overall quality seems to be what it should be for the price. Installation is only as difficult if you want it. Set up was relatively simple. Picture quality is great in daytime and acceptable at night using the IR feature. The layout of the NVR systems OS could be refined but overall it works. Improvments in the app would be beneficial but again it does its job. I installed this system about a month ago and would definitely buy again.

Do not buy - junk!

Do not purchase this system. I bought this system approximately 1 year ago and it has already quit working. There is also no support number to call for any issues.

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.

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.
