1.1 PRODUCT INTRODUCTION
The DVR-3704 is a unique low-cost, high-performance digital video recorder supporting a
4-channel video input, 4 alarm inputs and one alarm output. It records at a real time speed, and
displays video at the same speed rate per channel. Our device is capable of simultaneous triplex
recording, playback and live modes, and provides a multi-screen on which to view your recorded
images. Instead of having to handle inconvenient VCR tapes, you now have the hard-disk drive in
which to store your videos, enabling you to enjoy the extreme flexibility of digital image archiving.
You can access the images from any of your four channels rapidly and smoothly whenever you
wish.
In your recordings you can set different speed rates, qualities and resolutions as you choose, and
when you're looking for some particular records, you can use the search functions to search
through your records by record list, alarm list or time filter. You can play back your selected items
directly, and save the crucial images to a USB device which you can transfer to your PC to play and
print out.
Our digital video recorder further supports the network function in which you can use a remote PC
to connect with the DVR and retrieve vital images from a hard disk. You will be able to access both
video and audio records effortlessly. Use our device to bring your total environment under your
complete surveillance, archiving and control.
