4-in-1 AHD Video Capture Module Board USB 3.0 - 1080P 30FPS CVBS TVI CVI PCB for Security Camera, Medical Imaging, Conference & Live Streaming Integration

Product Overview

The 4-in-1 AHD Video Capture Module Board is a professional-grade PCB module designed for integration into security systems, medical equipment, conference devices, and live streaming solutions. This bare circuit board provides a complete video capture solution that converts AHD, CVBS, TVI, and CVI camera signals into USB 3.0 video streams.

This is a module board for integration - not a finished consumer product. It is designed for OEM manufacturers, system integrators, and electronics professionals who need to embed video capture functionality into their own devices, enclosures, or custom equipment.

Supporting lossless loop out, synchronized microphone audio input, and driver-free operation based on UVC/UAC standards, this module delivers stable 1080P at 30FPS and 720P at 60FPS real-time capture performance.

The module features self-developed hardware and firmware, enabling full OEM customization for PCB layout modifications, custom functions, firmware adjustments, and bulk production orders.

• OEM Customization Available – Hardware and software independently developed, supports custom functions and PCB design for bulk orders.

Technical Specifications

How It Works

The 4-in-1 Capture Module Board converts AHD, CVBS, TVI, and CVI camera signals into USB video streams. Once integrated into your device, it enables computers, laptops, and mobile devices to capture and record surveillance camera footage with synchronized audio input via microphone.

Integration Instructions

Step 1: Install the module board into your custom enclosure or device housing.

Step 2: Connect your camera signal source to the module's 4-in-1 Input BNC interface. If you need loop out functionality, connect to the Looping Out interface.

Step 3: Connect the module's USB Output to your computer via USB cable, or to your mobile device using an OTG adapter (driver-free).

Step 4: If audio input is needed, connect your audio signal to the Mic In interface.

Step 5: On your computer, open your capture software (OBS, PotPlayer, VLC, etc.), select the device "4in1_Cap Video" and activate it. The LED indicator will flash red, confirming successful signal capture.

Typical Applications

• Security Surveillance Systems – Integrate into DVR/NVR systems, security monitoring stations, or custom surveillance equipment to capture and record footage from AHD, TVI, CVI, and CVBS security cameras.

• Medical Equipment Video Capture – Embed into medical imaging devices, diagnostic equipment, ultrasound systems, or surgical recording devices to capture medical video output.

• Enterprise Video Conferencing – Build into conference room systems, video conferencing equipment, or professional meeting devices to integrate camera feeds.

• Education and Training – Install into classroom recording systems, training equipment, or educational devices to capture demonstrations and lectures.

• Fishing Detection and Exploration – Integrate into underwater camera systems, fish finders, or marine exploration equipment to record underwater footage.

• Live Streaming and Content Creation – Build into streaming devices, content creation equipment, or broadcast systems to stream surveillance camera feeds or create content using analog camera sources.

Important Notes

• This is a bare PCB module board intended for integration by technically skilled users, OEM manufacturers, or system integrators. It requires proper installation into a suitable enclosure or device.

• It is normal for the module to feel warm during operation. The circuit board is designed with wide temperature tolerance, and extended use will not affect device lifespan.

• For best performance, ensure your camera signal matches one of the supported formats (AHD, TVI, CVI, or CVBS).

• USB 3.0 connection is recommended for optimal 1080P 30FPS or 720P 60FPS capture performance.

• Ensure proper ventilation when integrating this module into enclosed devices.
