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.

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.

The video quality on this system is great and setup is a breeze. Motion detection is somewhat hit-and-miss so as part of a security system you would still want more precise intrusion sensors, however, this works great to provide recordings of past/event activity for future reference.

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 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.

We've had this system installed since the beginning of October and I could not be happier. Everything took about 8 hours to install properly and everything looks great. The quality of the video far exceeds my last system. The colors are sharp and the details are crisp and clear. I've got 6 of the camera's outside and they are able to cover everything that I need it two. The other two cameras I have inside pointing at my doors so that I can see who is coming and going. Being able to view the camera's in real time using the app has been extremely useful, especially while expecting deliveries or watching the driveway to see when my kids come home. Anything that you can do with the recording unit (NVR) you can do with the app, and I don't think I've had to plug the NVR into my TV for a while now after discovering how powerful the app is. Everything records in 4k and with audio so you can hear whats going on as well. I don't record 24/7, so I only have the motion and human detection turned on. Notifications are recorded in the app as well with a thumbnail, and when you click it you are taken right to that time so you can view the event on the player. If you need a system, you can't go wrong with this one.

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.

I purchased this system to upgrade my old camera system. The picture quality is top notch during day or night vision. The audio was also an upgrade as my old system did not have any audio capability. The app is also very powerful and quick. The ability to see, monitor and make changes from my phone is very convenient. I love this system and would recommend this and purchase this again.

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!

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!
