Signal Conversion for Legacy Security Cameras

The GRACETOP GTUS-AV2AHDWS adapter converts analog AV, CVBS, S-VIDEO, and HDMI sources into AHD format. It accepts both PAL and NTSC signals and outputs 720P or 1080P resolution at 30Hz. This allows older cameras or VHS equipment to connect directly to modern AHD DVR and NVR recorders.

Passive Operation with Built-In Protection

The unit draws power from an included 5V/1A external adapter, keeping the converter itself compact and silent with no internal fan. A dedicated ESD protection circuit guards the 1.25 * 4 pin input port against electrostatic discharge during handling or installation. Power consumption remains low in typical surveillance deployments.

Simple Integration into Existing Cabling

The converter bridges legacy cabling and current AHD recorders without requiring new coaxial runs. It ships with the necessary power supply and a user manual for immediate setup. Installers gain a cost-effective path to upgrade picture quality while retaining existing camera placement and wiring infrastructure.

Questions about this item

How do I connect my AV or HDMI source to the 1.25 * 4 pin port on the GRACETOP GTUS-AV2AHDWS?

Plug the source into the dedicated 1.25 * 4 pin input, connect the included 5V/1A power adapter, and select the correct PAL or NTSC format; the step often missed is verifying the source resolution is set to 720P or 1080P@30Hz before powering on.

What maintenance will the GRACETOP GTUS-AV2AHDWS need over time?

The built-in ESD protection circuit requires no user service; periodically check that the power adapter and cables remain firmly seated and free of dust to maintain a stable 720P/1080P@30Hz AHD output.

What is the first limit I will hit when running the GRACETOP GTUS-AV2AHDWS continuously?

The converter caps output at 1080P@30Hz AHD, so sustained use cannot exceed that frame rate or resolution regardless of the input signal quality.
