1 In 1 Out Composite Video Amplifier & RCA Connector
The 1 In 1 Out Composite Video Amplifier boosts and equalises a single analogue video signal so it can travel up to 1000 meters over RG59 coax without losing clarity. It’s ideal for CCTV cameras, DVRs and AV devices that suffer from dim or noisy images due to long cable runs.
Quick definition: A video amplifier is a small powered device that restores signal strength, sharpness and brightness to a composite video signal, compensating for losses in long cables and connections.
With adjustable sharpness and brightness, HF compensation and a compact ABS housing, this unit is a simple, reliable upgrade for any single-channel video link.

What does this 1 in 1 out video amplifier do?
This amplifier takes one composite video input, boosts its level and compensates for high-frequency loss, then outputs a clean, standard 1 Vp-p signal. It preserves picture quality when you need to send a single camera or AV feed over long distances or through patch panels.
It is commonly installed between a camera and DVR, or between a source device and a distant monitor, where it helps maintain brightness, contrast and detail.

1 In 1 Out video amplifier FAQs
Use this amplifier when you have a single video path that needs to run a long distance. A splitter divides one signal into multiple outputs, while this unit focuses on boosting one feed to maintain maximum image quality to a single destination.
The amplifier is designed for transmission distances up to 1000 meters over RG59 coaxial cable, assuming good cable quality and proper 75 Ω termination at both ends.
After powering the unit and confirming video is present, use the two front-panel controls while viewing your monitor. Turn the brightness knob until the overall image level looks correct, then adjust sharpness until fine details are clear but not overly noisy.
Yes. Any standard composite video source with 1 Vp-p, 75 Ω output—such as CCTV cameras, DVRs, VCRs or video players—can be connected, using appropriate coax and connectors.
