    I had two other manufacture systems prior to this one, and on comparison, the Defender system's quality and options are so much more superior. I am very impressed with this product.

    It was a Christmas gift. I absolutely love it! Very easy service up

    Wireless system was purchased as back-up for wired system already installed. I had a break-in and the DVR on the wired system was stolen, eliminating all evidence. It would be great if these systems allowed the use of a shadow DVR, wired with Cat 5 (or similar), to create a back-up copy in a remote location. Infrared video is grainy, but adequate. Otherwise, overall quality of both systems is excellent.

    stanley strassburg February 16, 2016

    I have had two other security systems and the Defender is by far a more superior product. I especially enjoy the long power cords for each camera and the pairing of each was very easy. This system has more capabilities than I expected. Perfect Product.

    great security camera easy to set up easy-to-use definitely will be buying more

    Meatlipps February 3, 2016

    Good cameras compared to what's out there. Hard to setup networking if your not used to that type of thing. Michael in tech support got us up and running very quickly, so I was thankful for that

    Wrangler05jw February 3, 2016

    Good quality of major components. Cables connecting routers to the DVR could be longer to allow greater setup flexibility. Most of the setup is intuitive. This system works for us!!

    Darrel January 30, 2016

    We bought our system last April, finally got around to putting it up. Super easy installation, and so far everything is great. Still learning how to work with all the features. Night vision is great, works better than we expected for the price. Only wish we would have bought the 6 camera system.

    myjunque d&b January 28, 2016

    Had to buy some extra cables and get help from our "techie" son-in-law for set up. GREAT pictures, able top locate cameras in crucial places, I love having it on iPhone too!! Feel a lot safer with Defender!!

    Bob January 28, 2016

    Did have a couple of problems setting up but finally got to talk to someone on live chat. They got me started and everything seems to be working well now. Picture s are clear and night vision is good.

    Wrangler05 January 27, 2016

    Fairly easy to put together and set up. Cables between routers and DVR could be longer to allow greater router height and separation from the DVR. Customer Service inquiry was answered quickly and completely.

    Janice b January 26, 2016

    This system is perfect for what i need, i have a camera on all 4 entry ways to my house. Day or night nithing gets by me. Night time vision is really good, day time is just like bein outside, very plain. Easy set up, finding a plug in for each camera is tricky but thats the only problem i had. Love it, highly recommend this system.
