Classification of main performance indicators of thermal imaging night vision devices
1. Resolution
Resolution is the most important indicator of thermal imaging night vision devices, and it is one of the keys that night vision devices affect the cost of thermal imaging night vision devices. Generally, thermal imaging night vision devices have three resolutions: 160*120, 336*256, and 640*480. The price ranges from tens of thousands to hundreds of thousands of yuan.
2. The resolution of the built-in screen
When we observe the target through the thermal imaging night vision device, we are actually observing the LCD screen inside it. The built-in screens of the top brands of thermal imaging night vision devices have very high resolution and clarity. For example, the built-in screen of RNO’s thermal imaging night vision device adopts the top OLED 800*600 screen. This allows for a clearer observation and a better field of vision.
3. Binocular or Monocular
Binoculars are significantly better than monoculars in terms of comfort and observation effect. Of course, the price of binocular thermal imaging night vision devices will be much higher than that of monocular thermal imaging night vision devices. The production technology of binocular thermal imaging night vision devices will be much higher than that of monocular. At present, only two companies in the world have this production technology, including RNO and HST.
4. Magnification
Due to technical bottlenecks, the physical magnification of thermal imaging night vision devices is only within 3 times for most small factories. Currently the maximum magnification that can be produced is 5 times.
5. External recording device
For thermal imaging night vision devices, well-known brands will provide external recording device options, which can be directly recorded on the SD card through this device. And also can carry out remote shooting through the remote control device.
