HDMI to AHD Converter for CCTV Systems

This converter translates HDMI signals into AHD format for integration with analogue high-definition surveillance equipment. It accepts one HDMI input and delivers two AHD outputs, making it suitable for installers who need to feed a DVR or NVR from an HDMI source. A 5 V power adapter and user manual are included in the package.

HDMI 1.4 input with HDCP 1.2 support

The HDMI input follows the 1.4 standard and handles HDCP 1.2 protected content. Supported input timings cover SD at 480i and 576i, HD at 720p50/60 and 1080i50/60, plus 3G rates at 1080p25/30/50/60. Output is limited to 720p or 1080p at 30 Hz, selectable by a button on the unit.

500 metre AHD loop-out repeater

The second AHD output functions as a loop-out repeater, extending the signal up to 500 metres over coaxial cable. This provides headroom for long cable runs in outdoor or large-premises installations. The converter does not support higher output frame rates or resolutions beyond 1080p30, so sources requiring 50 or 60 Hz output will be down-converted.
