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.

Very easy to install and setup! Used a 1” concrete drill bit to drill through brick, pulled wires through no problem. Two sets of wires will go through the 1” hole. Hardest part of the job is fishing the wires through the walls/ceiling. Buy a fish tape. Connection to DVR was simple with color coded connections on back. Connected cable to HDMI 2 on tv and labelled it PC, use tv menu and it’s right beside Netflix. Don’t use any IP or PTZ camera settings in PVR menu! Don’t go crazy adjusting menu settings but keep password strong. Setup Defender 4K APP and adjust cameras with phone right in front of you. On a scale of 1-10 for installation, I’ll give it a 8 for average person. For a pro, easy 10. At night time, use the APP to fine tune for night vision so the light lines up where you want to see. Daytime will be perfect after that. Simple

Faster than expected delivery, set up was simple, presale questions were readily answered and more importantly correctly answered. App works well. The system might be improved if computer could access dvr directly rather than having the intermediate step of downloading to a flash drive and then uploading to the computer, but this hopefully would be rarely used.

Shipping was fast. Video quality is good. 60ft cable length was insufficient and had spend more for 100ft cables. IR Motion detection is horrible at night. Triggers an alert for very big, fly etc. Customer service has not replied to two of my cases. One for warranty registration and other for tech issue. So looks like they don’t care much after the Sale. Mobile App is very basic. Downloading the video clip from phone is a hit or miss. It errors out most of the time saying “too short duration playback failed”. I am wondering if I made the right decision but this system based on reviews

Easy install. Booklet and online videos walk through process without anything missed. Picture quality amazing. Wired means never having to recharge batteries or lose signal. App on iPhone and iPad is terrific. Very happy that I chose the Defender system.

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.

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.

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.

Overall I love the Defender 4K and would recommend it to anyone. Only reason for the 4 star instead of a 5, is the cables on the cameras could make installations easier if the cable was 6-10 inches longer. Here in Florida you are almost always going through or over a cement block wall and it makes it difficult with the current length.

Came faster than expected. Unit seems solid and easy to setup. Have not yet been able to do a complete install of all cameras but what I have been able to get completed they are working well and great image. A good deal of settings to work through to tweak them as you wish. I have mine connected to my 55 inch tv in our living room and used a wireless mouse instead of the wired one sent. Works great! Choose the wired cameras as I have the space to hard wire them without the wires being exposed. This gave me the 2T hard drive as well as power and a better image so shouldn't have any issues with overwriting something that I may have wanted to keep. Still playing with the system but like it so far.
