VD641N Network Thermal Imaging Module

Product Overview
The VD641N Network Thermal Imaging Module is a compact network-based thermal imaging component featuring a 640×480 uncooled vanadium oxide (VOX) detector. It provides clear infrared imaging, multiple pseudo-color palettes, web-based monitoring, raw thermal data output, smart alarms, and remote configuration.
With plug-in-free web video playback, ONVIF Profile S/T support, SDK, and WEB API interfaces, the module is suitable for integration into various thermal imaging and network monitoring systems.

Key Features
• 640×480 uncooled VOX detector with 17 μm pixel pitch.
• Compact design for flexible system integration.
• Multiple pseudo-color palettes, including black hot, white hot, iron red, and rainbow.
• Athermal fixed-focus lenses reduce focus changes caused by temperature variations.
• Supports manual and automatic focusing with multiple optional lens configurations.
• Built-in storage temporarily saves images when an alarm event occurs.
• Web browser-based monitoring and configuration without plug-ins.
• Raw thermal image data available through SDK or client software.
• Supports ONVIF Profile S and Profile T for network integration.
• Supports SDK and WEB API for secondary development.
• Smart alarms including intrusion, boundary crossing, motion detection, network disconnection, IP conflict, and storage faults.

Working Principle
The VD641N uses an uncooled VOX infrared detector to sense thermal radiation in the 8–14 μm wavelength range. The detector converts infrared radiation into electrical signals, which are processed to generate thermal images. Images and data can be displayed through a web browser or client software and transmitted over Ethernet for remote monitoring and system integration.
