What are night vision?-Hiicam JNV30
When it comes to the word “night vision”, do you think that it can really see things at night? The answer is of course yes, even in the absence of moonlight and cloudy conditions, it can allow you to see things 200meters away.
Usually using thermal imaging – This technology operates by capturing the upper portion of the infrared light spectrum, which is emitted as heat by objects instead of simply reflected as light. Hotter objects, such as warm bodies, emit more of this light than cooler objects like trees or buildings.
When it comes to IR light, there are usually two types, one is 850nm and the other is 940nm; what is the difference between them? 850nm has red burst, 940nm does not. The so-called red burst refers to a visible red dot on the chip when the infrared lamp is working. So if concealment is required, using 940nm is a good choice. However, some customers will use black colloid 850nm to cover up the red burst, but if you pay a little attention, the red burst is still visible.
Application scenarios: Can be used for hunting, field life observation, military, security, law enforcement, etc.
Now Haiicam has a night vision device – JNV30. It uses a 2Mega CMOS sensor, 850nm IR LED, etc., and can digitally zoom five times, which means you can see things 200-300 meters away. If you want to know more about it, you can check it on our official website.
