What Is a 4‑Channel AHD Vehicle Tablet?
A 4‑channel AHD rugged tablet is an in‑vehicle Android device that integrates up to four AHD (Analog High Definition) cameras directly — without requiring external DVRs or video encoders. It serves as a combined display, recorder, and telematics gateway for fleet safety applications.
Unlike consumer tablets, which support only USB webcams, our solution provides hardware‑triggered, synchronized camera inputs with ignition‑controlled recording — ready for ADAS, DMS, 360° surround view, and passenger surveillance.
4‑Channel Rugged Tablet: Key Capabilities
4× AHD Camera Input
Direct connection to up to four AHD cameras — front, rear, side, and interior. Supports 720p/1080p.
4× Trigger Inputs
Connect to turn signals, reverse gear, brake, and door sensors for automatic view switching.
Real‑Time Upload
4G/5G + GPS enables live video streaming and event‑based clip upload to fleet platforms.
Vehicle Power Integration
9-36V wide voltage with ignition sense — recording starts/stops with the vehicle.

Frequently Asked Questions
How many cameras can be connected?
Both MDT880 and MDT865 support up to 4 AHD cameras directly via compatible cradles (CRD880 for MDT880, CRD865 series for MDT865). For projects requiring more than 4 cameras, an external camera hub can be added to support up to 5 total AHD inputs. Contact our team for custom camera configurations.
Does it support ADAS or DMS?
Yes. The tablet can run ADAS/DMS software using camera inputs. Our SDK allows integration with third‑party vision algorithms. Both MDT880 and MDT865 platforms support this capability.
Can video be uploaded in real time?
Yes. With 4G/5G and GPS, the tablet can stream live video or upload event‑based clips (e.g., harsh braking, trigger activation).
What's the difference between CRD880 and CRD865 cradles?
CRD880 is designed for MDT880 with 4 direct AHD camera inputs — ideal for standard vehicle video deployments. CRD865 series (for MDT865) offers flexible I/O options and supports external camera hub expansion for up to 5 cameras. Choose based on your tablet platform and camera count requirements.
Can I customize camera count or trigger configuration?
Yes. We offer hardware customization for camera count (up to 5 via hub), trigger inputs, and video recording logic. Contact our video integration team →
