stand-alone and/or networked video and audio recording device. It provides recording
capabilities for four camera-inputs and is capable of event, pre-event, or timelapse

while simultaneously recording in a network configuration. Each of the four channels can
record independently or simultaneously. Other features include:

Technical Overview
Your HRDE4X4 DVR incorporates a switcher and multiplexer for selectable multi-mode
display, digital motion detection, camera tiling, and event, pre-event, or timelapse
recording.
The DVR converts analog NTSC or PAL video to digital images and records them on one
hard drive. You can access recorded video from the hard drive or previously archived video
from a USB stick. You can watch live video while simultaneously recording.
