1 Purpose and Functions
The ACTii AC7305 active video splitter is a professional distribution device designed for use in advanced CCTV systems and multimedia installations. The device enables the distribution of video signals from 8 independent sources to 24 outputs, allowing the image from one camera to be sent to three different receivers (e.g., a recorder, monitoring display, and video processor) without signal quality loss.
The distributor is fully compatible with colour and monochrome camera systems, as well as VCRs and other signal sources operating in PAL, SECAM, and NTSC standards. Thanks to active amplification, the device eliminates signal loss resulting from splitting, guaranteeing high image quality on all outputs.
Main features:
- ✔ Support for 8 BNC input signals and 24 BNC outputs
- ✔ Active distribution system ensuring high quality of the split signal
- ✔ LED indicators signalling correct connection of individual input signals
- ✔ Standard 19-inch Rack housing (1U height) for easy installation in server cabinets
- ✔ Very low power consumption and stable operation in continuous mode
- ✔ Robust, metal construction ensuring durability and shielding against interference
Signal configuration information:
The device operates in an 8-section layout. Each of the 8 inputs has 3 dedicated outputs assigned. This allows for independent management of eight different video streams within a single central unit.

3 Installation and Connection
Device mounting:
The splitter is designed for mounting in a standard 19" Rack cabinet. Ensure at least 1U of free space. The device can also operate as a standalone unit on a flat, stable surface.
Connection procedure:
- Ensure all devices (cameras, recorders) are turned off before connecting cables.
- Connect signal cables from cameras to the sockets marked as INPUT (inputs 1-8).
- Connect receiver cables (to monitors or recorders) to the sockets marked as OUTPUT. Remember that outputs are grouped in threes for each input.
- Connect the included 5V DC power adapter to the power socket on the splitter and then to a mains outlet.
- Observe the indicator LEDs on the front panel – they should light up when input signals are active.
4 Safety and Maintenance
Safety rules
- Use only the power adapter provided by the manufacturer (5V DC).
- The device is intended for indoor use only.
- Protect the device from moisture, flooding, and extreme temperatures.
- Do not block ventilation openings if the device is mounted in an enclosed space.
- If the power cord is damaged, disconnect the device from the mains immediately.
Maintenance
- Clean the housing with a dry or slightly damp anti-static cloth.
- Regularly check the stability of the BNC plug connections.
- Avoid using aggressive cleaning agents or solvents.
5 Troubleshooting
| Problem | Possible cause | Solution |
|---|---|---|
| No image on all outputs | No power to device | Check power supply connection and mains voltage. |
| No image on a specific section | No input signal | Check the camera and BNC cable connected to the input (INPUT). Check the LED. |
| Image is noisy or dark | Impedance mismatch or poor cable quality | Ensure you are using 75 Ohm coaxial cables. Check that cable lengths do not exceed standards. |
