How Do Hidden Cameras Work

Hidden camera technology can be very confusing, and it can seem so irresistible that you may don’t even try to figure out how it works. Here we are going to make it much easier to understand how a hidden camera works.

Wireless Basics

A hidden camera uses wireless transmission systems to transmit a video, making them easy to hide and convenient to use. Although most cameras don’t require any cable, some camera models come with a power source cable.

Detecting the Image

The hidden camera captures videos with the help of light coming through the lens. Light detectors simply measure red, green, and blue and then combine them to display a complete video. Some cameras come with a motion detector that can track any movement in the area.

Transmitting the Image

All hidden wireless cameras are integrated with a radio transmission that converts recorded videos to radio signals at a specific frequency. That signal can only be transmitted to a receiver. The receiver device then picks up the signal and converts it into video footage.

Using the Footage

The receiver has multiple functions, depending on the purpose. If wireless hidden camera surveillance needs to be continuously monitored, the video can be displayed on the screen in real-time. Besides, the video can be saved to a specific storage media or memory card that is integrated into the camera.

Advantages of Using a Spy Camera

Spy camera is an outstanding device for providing security and rest of mind. Below we have described some of the major advantages of spy cameras.

When the focal length is shorter, you will view the larger field. For example, if the lens is 2.8mm you can watch videos at an angle of 100º. On the other hand, the higher the focus of the hidden camera, the smaller the angle of view.

How Does the Night Vision Feature Work on the Spy Camera

The night vision feature of the hidden camera enables you to keep a close watch on belongs. Basically, the night vision feature has three different methods: low-light, thermal imaging, and infrared illumination that we have described below.

Low-Light

The low-light mode uses an image intensifier that maximizes the dim light source. This mode is suitable for recording video with limited light sources that helps to identify any person easily.

Thermal Imaging

The most hidden camera has a thermal imaging feature that uses temperature instead of light to produce images. This technology produces a black part of an image when the object is cold, whereas the hot object forms the white part.

Infrared

Infrared illumination is a very effective feature of a hidden camera for night surveillance. It works with the motion detection feature; the infrared illumination lights up and captures images when the camera detects any movement.

How Are Spy Cameras Built?

In general, most spy cameras are integrated with commonly used objects in our daily lives. These are televisions, mobile phones, toys, ink pens, alarm clocks, etc. This type of camera is mainly used for home surveillance but can also be used for industrial espionage.

Smartphones, PC, or tablets can be used as receivers. Real-time video footage of the hidden camera can be displayed on the receiver, and video can be recorded on the camera’s memory card.
