Essential Info

Great for home or small business applications, this security system includes four wireless cameras and a four-channel DVR for hassle-free surveillance that can be set up in minutes.

Footage can be streamed from just about anywhere, whether from a monitor in your living room or your 3G mobile phone while on vacation across the country. You can even set up email alerts so you are notified of any changes around your property.

Each camera features 420 TV lines and 24 IR LEDs for night vision, capturing high quality images in low light settings. Record for up to 40 days with 1TB HD @25fps. The DVR includes a built-in and removable HDD rack and can be operated manually, via remote control, or via a USB mouse. Choose from four recording modes (continuous, motion detection, sensor activated, and timer). All four channels can played back simultaneously.

    Instructions are terrible. I would not recommend this system.
    Buella13 -- Texas   5/19/2012
    This is misleading it is not easily set up like it says. The instructions on the network part are very vague. Have had two network guys look at it and no one can figure it out. waiting now for someone from Astrotel to call back for supprt.
