This 4-channel IP video encoder from 3S allows you to get the robust features of IP with your existing analog system. When added on to your current system, you can immediately start leveraging all the powerful viewing, alerting, camera count, and failover protection features of IP, without having to purchase new IP cameras or DVRs.

The dual codec gives you the choice of either H.264 or MJPEG compression. H.264 reduces file size without eroding the quality of high-resolution video.

Video-enhancing processing features include 3D de-interlace, which reduces the motion blur that occurs during the interlace scan process, and 3D noise reduction, which reduces the static that is common with video signals.

Comes with 3-year warranty and 30-day money-back guarantee.
