Do you know the night vision camera phone can resolve the issue of 'How to find hidden cameras using mobile phones without using detector app' and 'see things through darkness', why it can do that? Today, we'll take you to discover the answer. IR night vision cameras are devices that allow us to see objects in low light or even complete darkness. These cameras use a special type of technology known as infrared (IR) imaging. In this article, we will explore how IR night vision cameras work and why they are able to see things through darkness.

How does an IR night vision camera work?

Different with a thermal camera phone, an IR night vision camera works by capturing the infrared radiation emitted by objects in the environment. This radiation is not visible to the naked eye, but it can be detected by a special sensor in the camera.

The sensor in an IR night vision camera is typically a charge-coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) sensor. These sensors are sensitive to infrared radiation and can detect it even in low light conditions.

When the camera captures an image, it converts the infrared radiation into an electronic signal. This signal is then processed by the camera's image processor, which creates a visible image that can be displayed on a monitor or recorded onto a storage device.

There are two types of IR night vision cameras: active and passive. Active IR night vision cameras emit their own infrared radiation, which is reflected back by objects in the environment. Passive IR night vision cameras do not emit any radiation; instead, they rely on the infrared radiation emitted by objects in the environment.

Why can we see things through darkness with an IR night vision camera?

Different with a thermal camera, the reason we can see things through darkness with an IR night vision camera is because of the way that infrared radiation interacts with objects in the environment.

All objects emit some amount of infrared radiation, even if they are not giving off visible light. This radiation is absorbed and reflected differently by different materials. For example, materials that are good absorbers of infrared radiation appear dark on an IR image, while materials that reflect more infrared radiation appear brighter.

In addition, some materials are better at emitting infrared radiation than others. For example, living organisms like humans and animals emit more infrared radiation than inanimate objects like rocks or buildings. This makes it easier for an IR night vision camera to detect living organisms in low light or darkness.

Therefore, whatever you want to detect hidden cameras, take photos at night, or see things through darkness, the IR night vision camera can do it. Here is the night vision phones list for checking out, if you are interested to get one.
