Have been using this for 3 months in all weather condition (sunny, rain, hail, snow, sleet) and they have performed so well. Very happy with them. 8 cameras have allowed me a clear 24/7 view of my bungalow and property. The app is great. Get all the notifications I need. The added benefit of the lotion detection lights are another amazing feature I love.

Installed in a day and very happy with the video quality. I don't use any detections, it's something I'm still on the fence about but I'll probably work on setting it up soon. Also, there is a way to use the app on the computer though using the software Bluestacks, it's a phone emulator for your computer and it's free.

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.

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..

The whole system comes well packaged in the box. Everything is nice, clean, and tidy which you'll see is carried on in the whole system and software. Everything is quality and is as simple to set up as possible. The hardest part for me was running the cables through the attic and finding the best locations for the cameras (about 8 feet or slightly higher), but it was well worth doing. Everything else was easy. The cameras themselves are solid in construction, and they produce clear images day and night. They seriously blow my old wired 720p system out of the water and are superior to my wireless 2k cameras. In addition, they have sound. My children have been in a few minor fights with each other and the sound really helps put what happened into perspective. With the sound I actually know why the fight happened. Unlike my old wired system, there is only 1 Ethernet cord per camera that goes from the NVR into the attic and out to the camera. You won't need to run a separate power cable. I'm very happy with everything. I love knowing that I can access the cameras remotely on my phone and not just on the DVR. You'll hear and see everything you need to and you'll have the ability to eliminate false alarms such as leaves falling, birds flying by, dogs walking by, etc, and just detect humans.

These are top notch quality camera's made out of metal. Purchased this 8 camera Sentinel Ultra HD series about 3 weeks ago and I am happy I upgraded. I had an older 8 camera 1080p setup from a different company and this one blows it away with the quality. People talking about quality issues have it setup wrong, or have other factors creating the issue. These camera's have infrared and led lights, which can be configured to be used or not. Coloured night vision is amazing and is best used with the led lights on the camera or other supplied light. You can configure it to be colour night vision with no infrared led or led lights turning on (daylight mode) but if you don't have enough light it will look dark and wont be able to see anything. People talking about false alerts are correct it will do that from time to time if not configured correctly. There are settings to configure the sensitivity of the dectection as well you are able to block certain area's suchs as tree's, bushes, or other things that move constantly with the wind blowing triggering the alerts. Once these area's are blocked they will not trigger the event and you will not get false alerts. No company has perfected this as you will see from many reviews of false alerts from any brand. However you can minimize it when its configured properly. I have mine set to record continously as well with motion this way you can get the full picture and also have a general idea when the event occured. The system is really easy to configure, but if you do have any problems contact support and they can guide you through to get it configured just how you like. If you are looking for a quality camera system, or even upgrading from an older system this is the one to get! One cord for each camera, easy setup plug and play, no extra power cords, no changing/charging batteries especially when its -30 lol

Install and set up was easy. Running wires in the attic is a challenge but would be for any brand. Recommend that you test all equipment and then pull wires and mount cameras. Note for possible improvement would be to use a better quality adjustment screws. They strip out very easily. Suggest using a high quality torx head screw. Had a problem with a couple of the cameras going offline, not sure why. I rebooted the NVR and they all reconnected. I had Lorex cameras for many years and I believe these are better quality and set up was much easier.

this is my second Defender system, the first being the 2k wireless. the difference between these two so far is night and day. a little more work to set up but worth it. down the road i'll be replacing the 2k system with another of these 4k nvr systems. hoping to have a video review up on youtube soon

We had 2, 16 camera systems installed in our business. They replaced our older system. The installation of the cameras was quite simple and the set up took little time. From a security perspective, we are pleased with the high quality of the video/feed and in reviewing past recordings, we found it easy to go back and find specific dates for review. Over the years we have had three systems and following our research, we are certainly pleased with the Sentinel Defender camera systems.

My overall impression of the 8 Channel 4K Sentinel NVR is very good. The system came well packaged with each camera packaged in it's own box. It was a breeze to setup with the cameras truly being plug and play. The NVR and accompanying app were configured within 10 minutes of unboxing. By far the most difficulty is running your cables to your camera locations. Take your time and plan where you'd like your cameras and the routes you have access to for the cable runs! The image quality of the cameras is fantastic and far surpasses the wireless cameras I used previously. The accompanying app is intuitive and easy to use. I was surprised at how little bandwidth this system uses. There are many options which can be configured around motion detection, notifications and schedules. Setting up and using this system has been a great experience and has provided a lot of value in a nice DIY package.
