I have been using Defender products for years. Love the Easy setup and the simplicity to review videos.

HCELLC November 30, 2015

Purchased a system which included the 21150 (8) channel DVR, (4) 21146 cameras, cables remote and power supplies. All ports on the DVR and cables are clearly marked. I had the system up and functional in a single room in about 15-20 minutes after opening the box. Remote access with a laptop required the assistance of customer support and took about another ½ hour. Very pleased with all aspects of both the hardware and customer support. This system meets our needs for basic surveillance on a 5 unit rental property.

The price was right for 8 cameras and a 2TB HDD. So glad I held off on buying one years ago. The widescreen cameras are crisp and bright. The cameras are also built like a tank. All metal top to bottom. I'm confident these cameras will last quite a long time.

Nitro November 30, 2015

Awesome, beautifully engineered, worked right out of the box.... but no paper-manual, and the instruction cd wouldn't play, either in my computer or on my blu-ray player. A quick chat on Defender's homepage fixed that, though.... a link to all downloads was provided, and they're sending me a paper-manual free! Only parts I added were stainless-steel screws with black-painted heads for mounting my cameras, and a 'borrowed' ;) VGA-cable to hook the DVR up to my TV. Plenty of cable provided; I hooked up all four cameras in my 1455sf ranch townhome, and had cable to spare even at the most remote location. Yay! I love the remote/mouse controls, and the IR image at night is superb! Consider this a four-and-a-half star review. Thanks again for a really nice product!

I bought this DVR about 3 weeks ago to replace a broken DVR for my security system. It arrived quickly and just as described. It was very easy to set up. I am very happy with my purchase.

MrMrs November 30, 2015

We bought this a month ago for security cameras around our home and like it because it doesn't take up much room, easy to operate, clear pictures and it works very well. I recommend it.

AnGer November 30, 2015

Got this to replace an older DVR that no longer recorded. So far there are no issues and the upgrades from the previous dvr are much nicer. The only thing that doesn't work is the CD that came with it for the installation instructions, etc.
It is very user friendly.

Susie November 30, 2015

I brought this camera system in February thru Groupon. The price was great and received it in a timely manner. I didn't get it installed until 8/5/14 and ran into a minor problem with one of the cables. After being frustrated about one camera cable I was able to reach a rep name Julie who resolved my frustration.

Jeff November 30, 2015

I bought the 3 wireless cameras and then the dvr. I never thought the notification functions would work with the dvr because all 3 cameras went into 1 port. It worked perfectly!!! The wireless cameras work great an give me flexability. Gonna add 1 more wireless and 1 wired
