Product Description
Product description:DT-NH921 is a new product developed based on the latest optoelectronic technology. The instrument uses a high-performance second-generation/third-generation image intensifier tubes. There are 3 versions: low-light version, video output version, thermal fusion.The version has excellent performance, small size, light weight, all-metal shell, uniform vision, clear imaging, simple operation, can be equipped with night vision image output, high efficiency, and the night vision can be changed by changing the objective lens (or connecting the magnification lens) The instrument has built-in infrared auxiliary light source and automatic anti-glare protection system. This product has strong practicability and can be applied to mili-tary observation, border and sea defense po-lice, public security surveillance, evidence collection, customs anti-smuggling, etc. at night without lighting. It is an ideal equipment for public security departments, armed po-lice forces, special po-lice forces, and guard patrols.
Product feature:
1.All metal housing, with excellent performance, small size, light weight .
2. Eyepiece spacing adjustable and we achieved Flip up down ON/OFF and side up down ON/OFF. (must use the original Detyl mounts).
3. Optional configuration: night vision video output, Wifi transmission can be achieved through Wifi signal transmitter .
4. The magnification can be changed by changing the objective lens (or connecting the multiplier lens)
5. Built-in IR , adjusting the light spot size.
6. In the auto mode, the IR is adjusted by environment brightness .
7. Thermal imaging function is easy to use , one-button switch, easy to operate.
8. Various thermal imaging modes, thermal imaging covers the full screen .
9. Built-in indicator light, prompt switch position function, low power indicator light keeps blinking.
10. Can be upgraded to low-light thermal fusion version with video output.
