The included 500 GB hard drive allows continuous monitoring and recording of over two years’ worth of footage! Your DVR sends an alert when your memory space is full so that you can choose to overwrite old video or stop the unit from recording. The built-in USB port gives you the option of backing up and transferring your video footage with a USB flash drive or external USB hard drive. And if you need to expand your storage even further, you can choose to record only when motion is detected. This DVR uses H.264 compression which maximizes recording time, transfers data more efficiently over the internet and you’ll use 50% less storage space than traditional compressions - MPEG4, MJPEG - while still benefitting from high-quality imagery.

Had the system for several years. the colors are not true. my green grass is brown, red is yellow etc. It does the job ok. thinking about upgrading, but not with this system unless they do some serious upgrades. Smart phone option does not work.. period
OUR NEW REPLACEMENT UNIT, IS OUTSTANDING. EVER FEATURE WORKS BETTER WITH THIS NEW DVR. YOUR TECHNICAL AND SALES DEPARTMENT WERE EXTREMELY HELPFUL. THANKS AGAIN.
I replaced a stolen unit with this new one and installing it was so easy, Because I'm not real good on computers or my I-phone getting help finally came through,
Daniela on the live Chat bent over backwards to help me, she tried to walk me through the iphone installation but to no avail, I know I caused her a headache but she kept after it and with the help of a e-mail for instruction on how to start from the beginning I was finally able to download the right way and now I have my place of business on my phone to view anytime anywhere.
I bought this online after getting some technical support via online chat. Product arrived within a week and was easy to set up. Pretty much plug-and-play. One negative is I could never get the system to work on my laptop. But it works great on my iPhone and iPad.
I bought this DVR because my DALHUA died. This product is much better & easier to install. I actually spoke with Sarah from customer support to tell her how satisfied I was.
The DVR is easy to set up. The inputs are clearly marked, and you can't make a mistake. The picture is clear with the attached monitor. It tends to pixulate over the internet.
The DVR has excellent features and is fairly easy to set up. I contacted Daniela in tech support and she was able to answer a few questions. I would recommend this system to others.
This DVR was by far the easiest, most trouble free device I have ever linked to a router and actually got it working the first try. While the APP may need some tweeks, overall my experience so far has been good.
I have been using Defender products for years. Love the Easy setup and the simplicity to review videos.
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.
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.
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.
