DC-101 V2

720P HD DTV CAM

50–950 MHz / 1200–1350 MHz

The DC-101 V2 is a 720P HD DTV CAM that outputs its captured video as a DVB-T digital TV signal, so any DVB-T compliant receiver can watch it over existing coaxial cable or over the air. It encodes H.264 1280x720x30 (or D1 PAL/NTSC) video with AAC mono audio and transmits across 50~950MHz and 1200~1350MHz.

50–950 MHz / 1200–1350 MHz · 2/3/4/5/6/7/8 MHz bandwidth · H.264 1280x720x30 over DVB-T

Features

  • 01 Painless upgrade to HD — Reuse existing coaxial cable deployment without any special requirement for cable & connector. DVB-T signal is so robust that even a degraded and aged cable can be used to convey HD signal perfectly.
  • 02 Easy and friendly user experience — There is no lousy network IP configuration and no need to use a desktop or notebook PC. It's just as easy as watching TV programs with a TV set or SetTopBox.
  • 03 Long Distance — Easily transmit HD video over a single 3C2V/RG59 cable for at least 500 meters long without adding any repeater. For wireless applications, the line of sight transmission distance may reach 50~100 meters at 0dBm RF radiation power and up to several kilo meters at 20 dBm. The real distance depends on the antenna design and receiver quality.
  • 04 Daisy-Chain Connection (Bus-Topology) — Multiple DTV CAM's with different channel configurations can share a single cable. It can dramatically reduce the cable deployment cost and effort.
  • 05 Real time protocol and Low latency — No frame drop in QEF (Quasi-Error-Free) condition, and low transmission latency.
