Great quality system!

The video quality on this system is outstanding. The NVR records without fail. Easy setup. Highly customizable settings if interested. The App also works great and playback is not an issue. My only negative comment is that I get many false motion readings, but it does capture all the real ones too so you are not missing anything. If you want a DIY standalone system that does not require a contract you really can not beat this system. This being a Canadian company was also a selling feature for me too.

Great POE system

The Sentinel system is exactly what I have been looking for! We loved the easy set up with 1 cable for footage and power! We didn't have to worry about power adapters or power bars. The great 4k resolution with motion detection is awesome! I have 1 camera in the backyard to check what critters that may be running by after the winter thaw!

The product works well and is very easy to install

I bought this camera system about 3 months ago and it has worked flawlessly since the beginning. It was very easy to install and the support is very responsive if you have any trouble. I own two defender camera systems and they both have been great. I would recommend them without hesitation.

Great Security Camera with great features

This is a great security camera with great features. The hardware is pretty good and easy to connect. The setting up the devices app is very smooth. The instructions are pretty accurate. The features of camera like setting up the color of the video recording and images is outstanding. Motion detection and night vision which are the main best features of the security camera is excellent. The only downside of this, is that this is wired camera therefore installing this by yourself is not that easy. If you want to run the wires clean in the house you have to do it in the ceiling along with electrical wirings and it may require professionals. For DIYers can still be done with a careful consideration of the aesthetic of the house. Other than that this security camera is perfect for the price and its features.

It's a great product for a great price.

I purchased a couple months back and I got to tell you it's a great product. It's relatively user friendly. The only downside is customer service which I understand and respect and hopefully that will change the staff is good at getting back to you ASAP when confronted with an issue..

Defender 4K Sentinel

I have been using this sentinel camera set up for about a month now. The installation of the cameras was easy to do. It did take some time to hide all the wires, which is to be expected. The NVR was very simple to set up and I did it without any problems. The picture quality is amazing on a 4K tv. I had no issues with setting the app up either. The steps are very well layed out. The quality of the picture during the day is absolutely beautiful. There is an option to record with black and white, or colour, or in smart mode. It's crazy how in smart mode when motion is detected at night, the scene gets lit up in colour and it is just as good as in the daytime. This was a nice surprise. For most of the camers I kept the sensitivity level on low. When turned up it will pick up rain and you will get a lot of notifications. Turning down the sensitivity helped with this issue. The cameras that are semi protected under an eve also help reduce false alerts. Just something to think about when doing the camera placement. I really like the app. It's easy to find and play your motion alerts. It has a playback feature that you can watch all your alerts for each camera. After playing the first video, it jumps to the next one automatically. We've had problems with bears in our neighborhood, so I use the playback feature to view captured motion alerts that happen at night. Overall I have had a good experience with the defender 4K Sentinel security system. I highly recommend this system if you want or need a good quality system with the best quality of picture. It's nice that the price doesn't break the bank too!

A great system to start with or to upgrade to!

We've used Defender systems for many years and run a number of their systems and devices. We recently updated to the Defender 4K Sentinel POE system and pleased to have done so! The setup was simple, well documented, great image quality, ease of updates and love the functionality coupled with the Defender Empower App, that we use on both IOS and Android devices.

The Defender System in A Medical Centre

The Defender Alarm System is AWESOME!!! The cameras now clearly monitor our hallways. We previously had major issues with students running up & down our hallways. The cameras recorded very clear & distinct photos that were given to the local high school. Problem solved!! The pictures on the monitor alert our staff when there is activity in the office. We love our system and Our staff are feeling very secure & safe. Patient & staff safety are Our #1 concern. ‘Wish We had installed The Defender System before. It's very user friendly & We can observe any movement from across the room. Recently the hydro was out (4hrs) the emergency lighting allowed Our office to carry on as usual. Less stress, NO more worries! Thank YOU Defenders!

Top of the market

This is my second set of defender cameras. My first set I got over 10 years ago and I was really pleased with them so I decided to upgrade and get the newest version. This 4K system is absolutely amazing. The quality of the photos, the video, and my favorite part of it all is the motion sensors that I get alerts for directly to my phone. I strongly recommend anyone in the market for a great security camera system defender is the one.
