Se ven muy bien pero cuando pasó una grabación no puedo hacerlo rápido y si busco algo que pasó nesecito saber la hora exacta y si no la sé tengo que estar todo el día mirando la grabación.y lo otro es que no tienen volumen pensé que era algo normal que todas la tenían.

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.

I installed Defender CCTV DVR in many place of my friends and families. It’s great results but in video I found one issue like movement vision is not good steady results are good. Example a person or car movement stretched not like Poe or nvr. Only this issue should be solved. Thanking you

Picture quality is quite good for the price, was surprised. Only thing I don’t like so far is that I had to mount a camera sideways to get a taller narrower picture to cover my whole driveway. The image on the app or display monitor is sideways and can’t be rotated.

We were very surprised on how fast the shipping was. We are thrilled with our 4KUltra HD Wired 4 channel system. The videos are amazingly clear! The app is outstanding. First time set up takes some time - - but all the while worth it! Everyone is impressed with the quality of the system. Worth every penny! I am looking forward to purchasing an additional couple of wifi cameras in the near future.

I was upgrading my system to 4K and was looking online and saw this deal for the system and 8 cameras. I installed the DVR and it saw my old cameras and seemed to work fine. I am slowly installing the 4K 8MP cameras as I have time. I had purchased another brand PTZ camera and had a problem with the video blanking out. Called Defender support and when I mentioned other then their brand camera they DO NOT SUPPORT anything but their brand no matter the issue. Even though the camera was supplying video to the DVR and the video on the DVR blanked out they didn't want to here it. I think the manual should be more in-depth for those who aren't novices. Other then that support was good and I am happy with it so far.

Camera system is a very good system. The only issue I personally have is the DVR fan is a little loud for me. My old system was in my living room so I did not want to move all the wires for my new Defender system. The app could be a little better. I have to open twice to get the cameras to refresh.

The unit works awesome. Had some issues getting it set up but figured it out. I know you have a on line service for trouble shooting but it would be nice if there was some sort of trouble shooting guide in the down loaded manual. Otherwise all is good. Thanks Much, Steven

Day two having this system so we are still getting to know it (settings); the image quality during the day is perfect and night is decent, our license plates are blurred but because we have Christmas lights up perhaps that has something to do with it? We also noticed the time and date stamp letters have black and white font which is strange.

Customer service to select the right camera was phenomenal. Defender took a lot of time to explain all options and differences between the systems. They assisted me with the best possible price and warranty. Cameras are super clear. Good mobile app to view while away from home.
