Overall is ok.

Overall is a good system but it’s a bit cheap material and they can make it better. Included cables could be longer.

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.

Awesome quality product, awesome cusomter service

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

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 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.
