Technical Advantages

  • Highly sensitive detection capability

Using an uncooled focal plane array detector (VOx), with an 8-14μm spectral response and a NETD of less than 35mK, it can accurately capture subtle temperature differences and provide clear and stable imaging.

  • Flexible function adaptation

It supports 1-8× continuous digital zoom, multiple pseudo-color mode switching, and scene mode selection, and can be conveniently controlled via the UART interface to adapt to various usage needs.

  • Wide range environmental tolerance

The operating temperature range is -30℃~+60℃, and the shock resistance is up to 1000g. It can still maintain stable operation in complex and harsh environments and has strong reliability.

  • Multiple hardware expansion

It provides 9mm and other lens options and is compatible with CVBS image interface, which can be flexibly matched according to actual scenarios to expand the scope of application.
