Frequently Asked Questions - ST-VDABNC-2 Security Tronix

What is the ST-VDABNC-2?

The ST-VDABNC-2 is a video distribution amplifier and splitter from Security Tronix. It takes a single video input and provides two amplified outputs, ideal for distributing CCTV camera signals to multiple monitors or DVRs.

How many outputs does the ST-VDABNC-2 have?

It has two outputs, allowing you to connect two display devices from one video source.

What type of power supply is required?

The unit requires a 12 VDC power supply with at least 500 mA. An appropriate power supply is included in the package.

How do I connect the ST-VDABNC-2?

Connect a CCTV camera to the input BNC port using a 75Ω coaxial cable. Then connect the two output BNC ports to monitors, DVRs, or other devices using similar cables. Finally, plug in the power supply.

How do I adjust the video output?

Use the Video Adjust potentiometer on the unit to synchronize gain (brightness), equalization, and sharpness for the best image quality.

What is the bandwidth of the ST-VDABNC-2?

The bandwidth is 250 MHz at -3dB, ensuring high signal fidelity for analog video signals.

Can the ST-VDABNC-2 be used for long cable runs?

Yes, it is designed for video signal restoration over coaxial cable and includes features like ground loop isolation and low pass filtering to maintain signal quality over longer distances.

Is the ST-VDABNC-2 compatible with HD cameras?

It is designed for CCTV analog video signals (composite video). It may not support HD-TVI or IP cameras without additional conversion. Check your camera's output format.

What is the maximum operating temperature?

The unit should not be installed in environments where the temperature exceeds 114°F (45.6°C) to ensure safe operation.

What should I do if I get no video signal?

First, verify all connections are secure and using 75Ω coaxial cables. Check that the power supply is plugged in and the camera is working. Adjust the potentiometer. If issues persist, contact Security Tronix support at 1-610-429-1511.
