HDMI to AHD Converter for CCTV Systems

This converter translates HDMI signals into AHD format for direct connection to DVR and NVR recorders in security installations. It accepts SD, HD and 3G HDMI inputs up to 1080p60 and produces 720p or 1080p AHD output at 30Hz. A front-panel button selects the output resolution. The unit is aimed at installers extending existing HDMI sources into coaxial-based surveillance networks.

Simple Installation with BNC Loop-Out

The device ships with a 5V 1A power adapter and requires only HDMI and BNC cables to operate. Built-in ESD protection guards against static damage during handling. A second BNC port provides an AHD loop-out that repeats the signal up to 500 metres without an external amplifier. No driver or software configuration is needed, so commissioning is completed in minutes on site.

Resolution and Distance Headroom

The converter comfortably handles standard-definition 480i and 576i, high-definition 720p at 50 or 60Hz, 1080i at 50 or 60Hz and 1080p at 25, 30, 50 or 60Hz input rates. Output is limited to 720p or 1080p at 30Hz, so higher frame-rate sources are downscaled. The 500-metre loop-out reaches most perimeter camera runs, but longer coaxial distances will need an additional repeater.

Questions about this item

How can I confirm the converter is working after connecting my HDMI source to the AHD DVR?

Check that the DVR displays a stable 720P or 1080P@30Hz picture and use the switch button to toggle between the two output resolutions if needed.

What comes in the box and do I need any extra cables for the BNC outputs?

The package includes the converter, a 5V/1A power adapter with cable and a user manual; BNC cables for the two AHD outputs are not included and must be purchased separately.

Which output resolution should I choose between 720P and 1080P@30Hz for my recorder?

Select 1080P@30Hz if your DVR supports full HD recording; choose 720P if the recorder only accepts 720P or if you need maximum compatibility with older AHD equipment.
