Functioning methods of the hidden wireless camera will be so irresistible that you may not try to discover how it actually works. Below, we have described how hidden wireless cameras work.

Wireless Basics

Hidden cameras use wireless transmission to send and receive photos that make them convenient to use and easier to hide. Some camera models may have a cable to get powered, or some have rechargeable batteries to get power. Besides, it is unnecessary to have a cable from the camera to the receiver to get images on the hidden wireless camera.

Detecting the Image

A hidden wireless camera captures images just like any other video camera. When light passes through the camera lens, it focuses on a small plate of light indicators. Light indicators only measure red, green, or blue light, and then groups of three detectors are coupled to display a full image.

In a black and white security camera, each pointer only measures how much light there is in a compressed zone of the image. Some wireless cameras come with motors and motion detection features that follow all movements in the area.

Transmitting the Image

Wireless hidden cameras contain small radio transmitters on their board. When the camera combines a complete photo, it turns the photo into a radio signal at a specific frequency. Although this transmitter is not powerful, it is enough to transmit the signal to a receiver in the same house. If you want to constantly monitor the hidden wireless camera, the video can be shown on the device’s screen in real-time.

Using the Footage

The receiver has many functions depending on your purpose. If the hidden wireless camera wants to be continuously monitored, the image is displayed on the video screen in real-time. The photo can be recorded in certain storage media or in your device storage. Sometimes the receiver saves a few frames per second, creating a time-lapse photo of an area.

Most wireless hidden cameras come in small sizes so that they are easy to hide. Now, you may think about how long a hidden wireless camera can record.

Basically, a wireless hidden camera’s record capability depends on several factors, such as storage capacity and power of the battery. Generally, most hidden cameras have a recording capacity of 1 to 5 hours before the battery power is discharged.

This thing also depends on the camera’s memory storage space. Besides, if the cameras used night mode during nighttime, the recording time would be reduced to 30-50 minutes as the night vision mode consumes more power.

How Do Wireless Hidden Cameras Get Power?

Wireless hidden cameras need the power to continue the recording process. Below, we have demonstrated how hidden cameras get power.

Electric Source

These types of hidden cameras are connected with wires that help to get power constantly. These cameras are known as wired hidden cameras, but they can transmit footage wirelessly to the phone, tablet, or PC. The recording capacity of these cameras only depends on memory storage.

Battery Power

You will find some hidden cameras that don’t have any wire. These types of cameras are ideal for where there is no main power option available. Basically, these wireless cameras get power from their inserted battery. The downside of this camera is that you have to frequently charge or replace its battery to keep the camera recording.


A hidden wireless camera allows you to monitor your house or apartment using a simple app installed on your smartphone. Without the subject knowledge, these types of cameras can be used for several purposes. For this camera’s size, one question may arise in your mind about how they actually work. For that, through this context, we have tried to let you know how hidden wireless cameras work.

Typically, a hidden camera broadcasts videos using wireless transmission technology to send and receive images. First, it detects the image through the lens and turns it into a specific frequency. Then the receiver grabs the signal and converts it into the video again.
