[This review was collected as part of a promotion.] We installed the Defender security system over the weekend. It was very easy to install with the manual and went onto the Defender website and found out how to install the app on our phones which was easy as well. The performance is great. with long range, with wide views and is motion detected. Our cat had been in may of the views that's for sure. Love the fact our home is protected and we can see whats going on while were not home. I highly recommend this system to anyone looking .

We purchased three units for our school facilities. All three boxes were missing the camera power adapters; but after contacting support we received them within a few days without any issues. I've installed 8 of the 16 cameras from one of the units so far; it's a slow process but well worth it. I have had to order some longer cable lengths as 60' isn't long enough for some areas. The daytime picture quality is really great on the 43" HDTV (I have yet to try it on a 4K TV). I was surprised at how good the picture quality was at night on both inside and outside cameras. I am able to access the cameras on the app only when I am at school on the same network; I need to do some research into what settings to enable to view it when at home or away from school. Otherwise, the app works great with both live and previously recorded video. I am looking forward to getting the rest of the cameras installed and figuring out the app settings for when I am away from school. I highly recommend this system!

This system replaces my 4 year old Defender system where the hard drive failed after 4 years. Defender gave me a 10% discount on a new system. Bought 2 systems one for at home and the other for my vacation property. Easy to set-up; where I had issues customer support was excellent. Disappointed that this system can't be viewed on a computer. I was told this might be developed in the future. Cell Phone APP is great! Also, it was difficult adjusting the cameras with the tiny Philips head screws. HD camera viewing is excellent!

[This review was collected as part of a promotion.] This system is absolutely great. It has everything you need to monitor your home. You have four cameras that provide beautiful color 4K pictures, and they are weather resistant. It has a DVR to save your video footage for review. You can also check remotely from an app on your phone. I was really impressed that an HDMI cable was included so that I could hook the system right up to my TV to view. There is no monthly cost for monitoring and I see no need for a contract security service. There is even a window decal to announce that your home is protected. I highly recommend this complete, affordable system for everyone.

This system was a very easy setup and was crystal clear and able to give us this vision that we were looking for. And also gave comfort to an area that was well needed to be monitored. Having this system place in foster home will be a great help to which child is doing what as well as protection by knowing if anyone is outside creeping around.

[This review was collected as part of a promotion.] My husband has a lot of expensive toys that need protecting so this security system is great! Easy install....love the alerts you can get straight to your phone which comes with a warning text as soon as motion is detected by the cameras. Straightforward directions for set up with mobile phone use. The equipment is very durable and should last us for years to come. My husband likes the extra security since we have three precious teenage daughters

Mobile app has less functionalities that it's wrote on your website (notifications, filter). Many configuration are only available through connecting a screen on the unit (mine is in my house roof). Web configuration is limited and plug-in seem to be a malware and anyway plugin is not working at all.

I really like the quality of the camera and the quality of the picture. I have previously purchased defender cameras and i noticed the difference in the picture quality compared to the 4K. I have had issues connecting to the internet to view remotely and haven't been able to get a hold of a good helpful video or information sheet to help set up.

[This review was collected as part of a promotion.] These are the very first security cameras that we have owned. The product came all neatly wrapped in a box with everything that I would need included. The only thing I needed to provide is a viewing monitor or TV. The company even provides a free app to go with the cameras that has come in handy for easy viewing. There are no contracts or monthly payments with this security system. That is a big plus in my mind. I get to do all of the monitoring myself. My system included four cameras which is perfect for us as we put two in the front of our house and two in the back. We live in a rural part of our state and having extra security we felt was a great need. The ease of setup for this system wasn't too bad. It did take some time to get everything installed and in place but it is worth every penny. I was very happy to see that Defender includes everything you need to make the cameras work including a mouse and HDMI cords. You don't need to spend any extra money on this product after you get it home. It's as easy as taking it out of the box and installing it and protecting your home. I feel much safer in my home with these cameras and highly recommend this company.

I had a defender before but it died, I looked at the other products but didn't like the reviews so I decided to buy the 4K defender, It does work with my old cameras, I will install the 4k cameras once the snow is gone. Only issue I have to getting the camera's to display on my PC, will call support for assistance.
