How the K6204 4CH Mobile DVR System Works
The K6204 connects up to four AHD cameras with local video storage, a driver monitor, GPS positioning, vehicle power, and remote fleet management through 4G or a wired network.
1. Capture Vehicle Video
Up to four AHD vehicle cameras connect to the K6204 through secure aviation connectors. The cameras can cover the front, rear, sides, cabin, or cargo area of the vehicle.
2. Record and Store
The K6204 compresses the footage in H.265 or H.264 format and records it on one 2.5-inch HDD or SSD together with one TF card. Loop recording supports continuous vehicle operation.
3. Display and Manage
Camera video can be viewed locally through the connected driver monitor. A compatible CMS platform can provide remote video access, playback, positioning, event management, and fleet monitoring.
For projects that need a compact camera-integrated recorder instead of a separate HDD or SSD unit, compare our 4G AI dash cam solution .
HDD and SSD Storage Options
The K6204 supports one 2.5-inch HDD or SSD as the main storage device. It also supports one TF card for additional vehicle video storage.
A hard disk can be suitable when storage capacity and cost are the main priorities. An SSD has no moving mechanical parts and is often preferred for vehicles operating in environments with frequent vibration.
The system supports loop recording, video search by time or recording mode, multi-channel synchronous playback, and fast forward or reverse playback.
Storage capacity is not stated here because supported capacity can depend on the selected drive, firmware, recording resolution, frame rate, and project configuration.
Storage Structure
- 1 × 2.5-inch HDD or SSD
- 1 × TF card
- H.265 or H.264 video files
- Automatic loop recording
- USB video export
- Optional external fireproof backup box
Please confirm drive capacity, interface compatibility, formatting, and required recording time before purchasing an HDD or SSD locally.
For fleets that need high-capacity local storage, the K6204 4-channel HDD/SSD mobile DVR supports four AHD cameras, built-in 4G and GPS, removable HDD or SSD storage, and optional AI functions.
4G, WiFi, GPS, and Fleet Platform Support
The K6204 provides several network and positioning interfaces for fleet projects. Available remote functions depend on the selected model, network, SIM card, CMS platform, and software configuration.
Built-in 4G
Cellular connectivity can support remote vehicle monitoring, video access, event management, and communication with a compatible fleet platform.
GPS / BD Positioning
The positioning module supports GPS/BD and GPS/GLONASS configurations for vehicle location and route-related fleet functions.
Wired LAN
An RJ45 network port is available for wired network connection or supported project integration.
WiFi on K6204-G6
WiFi and the WiFi antenna interface are supported only by the K6204-G6 configuration.
CMS Platform
A compatible CMS client can provide video playback, analysis, device management, and other fleet functions.
Two-Way Intercom
The SPK interface can connect an intercom handset or speaker for communication between the vehicle device and platform.
Optional ADX and ADXB configurations can add driver assistance and monitoring functions. Learn more about driver behavior monitoring for commercial fleets .
