Two years’ worth of footage storage
The included 500GB hard drive allows for continuous monitoring and can store over two years’ worth of recorded footage! Your DVR will send an alert when your memory space is full so you can choose to overwrite old video or stop recording. Back up and transfer your video footage with a USB flash drive or external USB hard drive with the built-in USB port. 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.

Ultra hi-res, color enhanced imagery
600 TV lines of resolution bring you crisp, ultra hi-res video. In addition, when the lighting conditions are unfavorable our Advanced IR filter will automatically activate. The enhanced image processing filter purifies reds, greens, yellows and blacks, that may have otherwise appeared washed out or faded leaving you with superior color-accurate video footage important for identification purposes.

When everyone else is asleep, your cameras are watching closely
The things that go bump in the night are sometimes a thief making off with your big-screen TV. DEFENDER® cameras are equipped with automatic night vision. Thirty-six infrared LEDs provide clear night vision footage from up to 100ft away in complete darkness. Thieves may think they’re lurking around undetected but you can rest assured you will see them with DEFENDER®.

Instant email alerts if activity detected
Instantly know if any suspicious activity is happening on your property. This system will send you an email alert, complete with a photo of the activity, if any motion is detected or if cameras experience video loss. Even if you aren’t watching when something happens, you’ll know immediately if something is wrong.

Automatic remote viewing setup
Our 1 Step™ Remote Viewing software application auto-networks your DVR in less than 5 minutes. Simply input your DVR’s IP address (found in the menu) into the connection program on your computer, click “Sync to Router”, and 1 Step will automatically do the rest. This software is available as a free download for PC and Mac. Defender offers you the convenience of mobile viewing without any complicated instructions or hassle.
