For the price, decent picture and after a couple of hours of adjusting the settings and connecting the app, things seem to be fine so far. Better image than my old 720p cameras from 2015 from Samsung, but only gave 4 starts because the old cameras had a metal base / metal pivot socket / metal adjusting ring, while these cameras are all plastic and quite lightweight by comparison, but that does not mean they will not last as long or stand up to inclement weather - here's hoping. . .

Specs describe the camera at 15 FPS capability. Other systems I was looking at were only 7. Once I was into settings, was disapointed to find that 8 Frames per second was the max that it seems like it can handle. It has a 15 FPS feature, but only in the substream. still a decent quality camera. Instructions for getting the mobile app to properly work were not the best, but tech support walked me through it. Would be nice if one camera came with an audio feed, since the DVR supports it.

Excellent value for your money.The product is carefully packaged and was received within 3 days of ordering.Installation can be a bit tricky if you decide to hide all the wires as I did.The picture quality is excellent especially if you connect to a 4K monitor.

I purchased the new 4K HD 1TB 4 camera system as my other HD unit only included (2). Overall the display is "super crisp". That is a plus, however my older system allowed me to see a greater area of coverage. I expected a wider viewing range as it advertises and it being 4K, but honestly it really gives you a lot less viewing area. Picture width horizontally in comparison to the HD unit is actually the about the same, but vertically (top to bottom) it cuts off "a lot". In the most important area of my home facing the road and my front porch I am now having to use (2) cameras to see what I could see previously with just the (1) camera. I have adjusted every camera detail withing the easy to use unit, and I cannot get a better coverage image. Overall, the clarity is amazing with true 4K live display up to 15fps. On the upside, I can now read license plates on parked cars, I can see extreme details of objects I couldn't see before at the cost of previous coverage area. I don't know if this is supposed to be the give and take of greater quality picture, but I could see plenty enough detail before of people, objects, etc, before this upgrade. The system is not all bad, the connection to the internet was simple. Within minutes I was able to stream live view right on my android phone. Which actually helped me with the installation because I could use my phone to position the cameras. Kept me from going up and down a ladder a hundred times to get an optimal view. I really hope this review helps others when considering to make this purchase.

Wanted to wait until everything was up and running before this review. Cameras have very crisp pictures and videos. Alerts work as intened and the livee view is nearly perfect, (we have dsl so a slight delay). Had a few hiccups on getting it working smoothly. I recommend if you have an older B&C cable system, you run the supplied wires. Ours would not go into night mode and took a few days to realize that was the issue. These cameras require the beefier cables that can deliver more power to the better night vision these offer. Had some issues with it connecting to the app, but the customer service was very helpful. They do most of their corresponding via emails, but can set up a time to talk if needed.

Great system, very user friendly, and great cameras. The only regret I have is not getting the 4 cameras. Its way cheaper to get the bundle compared to buuing a 3 camera system and finding out you could use another one. Cameras are sold individually at a much higher price.

This system is very good. It has a very clear picture and a very wide view range. If you have a 4K television or monitor it will look great. But it will work with a regular basis monitor. I have had Defender systems for years. I have even installed them for some business. I highly recommend this company and their equipment.

This is actually my second Defender security system. I loved my 8 channel 4 camera HD 720p system I bought years ago so much that when I decided it was time to upgrade to newer equipment I knew I trusted Defender and was unsure I would like any other security system so I bit the bullet and got the 4k 16 channel system with 8 cameras. It took me a while to set it up because my old system was still working so I had the luxury of waiting for cooler days to run the cables through my hot attic. I'm very impressed. I knew that the 4k should be clearer and easier to zoom into but when I actually plugged it in I was shocked how much detail I had been missing. The system almost has too many controls. I'm still learning all of the new features. I will say that the outside cameras brightness was set to be to dim at first but thankfully it was an easy adjustment to make them brighter. I assume to is some auto adjustment due to the sun since the indoor cameras default setting looks great. I already know I will have many years of quality use with my new Defender system and I look forward to buying another one in the future.

Great quality with easy to understand startup instruction guide. Everything was in the kit to get the system up and going. This system is self contained where the video data is stored safety on your local high capacity DVR with no monthly fees that never end. The system is highly customizable to fit your unique needs.

Picture Quality is great. Would have liked to have been told what was needed prior to purchasing it for the sound to record. Also, would be nice if Defender attached to my computer and backed up to the hard drive instead of a USB Stick. Just minor things that would make it even better.
