Defender 4k Ultra Wired Security Camera System. Indoor & Outdoor Security Cameras Night Vision Mobile Viewing Motion Detection for Home and Business (16 Cameras)

Great picture and quality for the price. The system is easy to setup and is well worth the investment. I have helped several people set this system up at their home and business. Have had no problems with any of equipment

Owning a 1080 - 8 camera system, I wanted to buy the 4K - 16 camera system, and reuse 8 of the 1080 cameras along with 8 - 4K cameras. The help desk was absolutely unable to figure out how to do that, so I drew up a schematic diagram for them to have their engineering section look at; which they eventually approved. BTW, it works very well. I used the 1080 power supplies with the built-in ferrite beads on the 1K cameras and the original cabling without ferrite beads for the 1K side.

Let me start by saying I was very nervous about purchasing this system. I'm NOT computer savoy and neither is my husband! We purchased the 16 camera 4K system to replace an older system we had for our business. Let me say, watching the You Tube videos a bunch of times made the process very easy! The set up was pretty simple, but I suggest watching the video's for me at least it helped tremendously! We just replaced the camera's we had so we had all the wiring in place, so that cut a lot of time off the installation. I would recommend buying this system!

Great product with awesome Monday through Friday support! The live chat has always solved any problem and questions about modifications to the system. I enjoy the push notifications for alerts as to something going on. Great system! Incredible price! Excellent customer service!

So far we are very impressed with the 4K Ultra HD security system! We have only gotten around to installing one of the cameras since figuring out the wiring to and from the camera can be a bit of work. But 2 days after installing, we were able to capture a man breaking into one of our cars parked outside. We are extremely grateful that we had that camera running because its providing very useful evidence for the police. Make sure to avoid any obstructions in the path of the camera to maximize the night vision capabilities! We originally had a bit of roof line in the shot which caused a lot of glare. Once we tilted the camera down the quality improved A LOT! Day time quality is 10/10! It was also very helpful to watch the set up video on the Defender Youtube page! Also, Defender 24-7 app is working very well for us on our iPhones! No crashes or lag. The Motion Sensor alerts are very helpful as they record about 2minutes every time they are triggered which makes it very easy to save video/photos without having to playback and scroll through the footage.

Recently purchased this system, its it is very good for the price, image quality is just enough for surveillance of your home. Defender maybe though can look into offering some compatible LPR technology in the near future to be able to see/ provide lisence plates to authorities during a hit and run or something.. thank you guys!!

It is great picture quality but it takes a lot to set this up correctly. The interface looks like it was made in the 1990's, but gets the job done with a lot of clicking around. Cameras are light and easy to place. Night vision is super clear as well. I think after I mess around with the settings I'll feel better about it all. Same goes for the iOS app - lots of clicking around. They are trying to update it currently.

Fairly easy to install but the app lacks functionality and one of the cameras didn't work

doesnt have a desktop app. had i known, i would have never purchased. the quality is okay, but close to the same as my qsee system i replaced it with that i purchased 6 years ago. disappointed

I did not receive The Defender Camera System. I got just the DVR in a box. Period. It was returned.
