Receiver ACT AC7853 HDMI over CATx — receiver for HDMI signal over Ethernet up to 150 m

Receiver ACT AC7853 HDMI over CATx is a compact device that receives HDMI signals transmitted over standard CATx cabling at distances up to 150 m when used with a compatible transmitter. It restores full HDMI video and audio at the display end, allowing source equipment such as PCs, set-top boxes or media players to be positioned far from TVs, projectors or monitors. The unit is intended for installations in meeting rooms, classrooms, retail digital signage and other environments that require extended HDMI reach without running long HDMI cables.

Advantages

The ACT AC7853 receiver supports transmission over existing Ethernet infrastructure, reducing installation complexity and cost compared with long HDMI runs. It preserves HDMI audio and video signals over distances up to 150 m and provides a discreet receiver form factor that is simple to mount near displays. The device interoperates with compatible ACT transmitters to deliver a stable link and simplifies connecting multiple source locations to remote displays.

Suitable for

• Conference rooms where source equipment is located in separate AV racks
• Classrooms and lecture halls requiring centralized media distribution
• Retail and hospitality digital signage installations
• Home AV setups needing long-distance HDMI connections without signal loss

How to use

Install the ACT AC7853 receiver near the display and connect its HDMI output to the TV, projector or monitor using a standard HDMI cable. Use a single CATx cable to connect the receiver’s RJ45 port to the compatible ACT transmitter located near the source device. Power the receiver with the supplied external adapter. After making physical connections, power on source and display; the receiver will restore HDMI video and audio from the transmitter, allowing remote sources to be viewed on the local display.

Usage recommendations

For best results, use high-quality shielded or unshielded CAT5e/CAT6 cables with proper termination, minimize intermediate connectors and avoid running CATx alongside high-voltage power lines. Verify compatibility with the paired transmitter model and test signal quality at the intended run length; for runs approaching 150 m, confirm resolution support and power requirements in your specific setup.
