Video converter INNE OVH-4D/SC 4x VIDEO RS-485 set

INNE OVH-4D/SC 4x VIDEO RS-485 set is a compact video converter pair designed to transmit four analog video channels together with an RS-485 control line over extended distances. The set allows integration of CCTV cameras and other analog video sources into structured transmission systems while preserving the PTZ or serial control functionality via the RS-485 channel. The product is intended for installations where distance, cabling simplicity and combined video plus control transmission are required.

Advantages

The OVH-4D/SC set provides simultaneous transmission of four video signals and a shared RS-485 data path, reducing the need for separate cabling runs. Its compact design is suitable for installation in equipment racks or small enclosures. The set supports preservation of camera control signals, enabling remote PTZ operation without additional converters. The design emphasizes straightforward signal pairing and compatibility with common analog CCTV systems.

Suitable for

• Multi-camera CCTV installations where combined video and control transmission is needed
• Remote monitoring sites requiring extended cable runs for video and RS-485 control
• Integration of analog cameras into hybrid transmission systems

Key specifications

• Number of video channels: 4 analog composite video inputs/outputs
• Control channel: RS-485 serial data line for PTZ or device control
• Transmission format: separate video pairs with combined RS-485 path (set includes both transmitter and receiver units)
• Mounting: compact housing suitable for rack or enclosure placement
• Compatibility: designed for standard analog CCTV cameras and RS-485 control protocols

How to use

Connect each camera's composite video output to the corresponding VIDEO input on the transmitter unit and connect the RS-485 control wires to the designated RS-485 terminals. Install the receiver unit at the remote location and connect its VIDEO outputs to the monitoring device or recording equipment, then connect the RS-485 terminals to the PTZ controller or serial device. Power both units as required and verify video signal and control responsiveness. Use shielded cabling where recommended to maintain signal integrity over longer distances.

Usage recommendations

For reliable operation, route video and RS-485 wiring away from high-voltage power lines and large electrical equipment. Use quality coaxial cable for video connections and twisted-pair cable for RS-485 to reduce interference. Verify RS-485 polarity and termination when integrating with PTZ controllers, and test each channel after installation to confirm proper video and control transmission.
