Product Code: AHD-CV12



The AHD-CV12 is a HDMI to AHD video converter box that supports 720p and 1080p video resolution. AHD stands for "analog high definition". It is a video standard that uses RG59 coaxial cable and BNC connectors to transmit high definition video.

The AHD-CV12 video converter supports many applications. When the AHD-CV12 is paired with an HDCV-3-T AHD to HDMI converter, an HDMI over coax converter box solution is created that supports video transmission up to 300 meters / 1000 feet using RG59 cable. Need to send your HDMI video signal further? You can add video extender / amplifiers to boost the signal up to 5000 feet / 1500 meters. CCTV Camera Pros has supplied this solution to many retail and commercial customers for use in live security camera display monitors.

HDMI over Coax

HDMI over Coax

The above wiring diagram shows how the AHD-CV12 can be used with an HDCV-3-T to create an HDMI over coax converter box solution. This is how it works.

  1. The HDMI output of the iDVR-PRO surveillance DVR at the top of the image is connected to the HDMI input of the HDMI to AHD converter.
  2. One of the AHD BNC video outputs is connected to a BNC monitor that supports 1080p AHD video. Please note that use of this BNC monitor via the second BNC output is optional.
  3. The other BNC output is connected to the HDCV-3-T BNC to HDMI converter.
  4. RG59 coax cable with BNC connectors is used for the connections to both monitors.
  5. The RG59 cable can be run up to 1000 feet. If you add this AHD BNC video amplifier, you can run RG59 up to 2600 feet.
  6. The HDMI video output of the AHD-CV7 is connected to the HDMI video input of the TV at the bottom of the diagram. This is a standard HDMI TV.

HDMI to Coax with Amplifier Extenders

HDMI to Coax

Here is the AHD-CV12 being used in an HDMI to coax system with the optional AMP-101HD amplifiers / extenders. When one AMP101HD is used, the max distance of the coax cable extends to 2600 feet. When two are used, the max coaxial cable distance extends to 5000 feet. An HDCV-3-T video converter is used at the display end to convert the coax back to HDMI.
