Defender Ultra Hi-Res Security Systems with 500GB Hard Drive & 600 TVL Night Vision Cameras

BlueLine’s security systems offer levels of surveillance typically found in professional installations. The weather-resistant night-vision cameras capture high-quality footage that you can access from almost anywhere.

Multiple Cameras and Channels

Multiple cameras help you keep an eye on multiple parts of your home or business or get a better angle on what’s going on in a particular room. If you choose an option with more channels than cameras, you’ll be able to expand the system if you ever need to.

Weather-Resistant Night-Vision Cameras

Weather-resistant aluminum housing helps protect cameras from the elements, and IR LEDs allow the cameras to see up to 75 feet in the dark. That means you can install the cameras anywhere: inside or out, lighted or not.

Easy Access to Footage

Included 1 Step remote viewing software instantly links the DVR to the Internet, so you can watch the camera feeds live or review previously recorded footage. You can access the footage on a smartphone, tablet, or computer, making it easy to keep tabs on things or rewind to the moment when the Hamburglar snuck in the back door.
