Wi-Fi spy cameras work just like any other Wi-Fi security camera around. The biggest difference is their portability, size, and ability to be disguised as random household or daily-use objects.

We call them ‘Spy cameras’ as they are not visible to the subject in focus. Moreover, you can easily hide them in the most commonly used objects like alarm clocks, smoke detectors, desk lamps, etc.

What are Wi-Fi spy cameras?

Wi-Fi spy cameras transmit video signals to a smart device instead of storing the footage in the Internal memory via a wifi network.

Besides the smart device, these Wi-Fi spy cameras can send the same footage or recording to cloud storage.

The purpose of using these wifi spy cameras could be anything – keeping an eye on your babysitter or spying on a cheating partner.

Regardless of the reason, you must adhere to the existing state laws and regulations related to using video surveillance devices for a given purpose.

Understanding the process regarding how Wi-Fi spy cameras work

A Wi-Fi spy camera boasts a wireless RF(radiofrequency) transmitter that facilitates broadcasting the video captured by the camera, which is further pulled out by a receiver.

The same receiver is then connected to a smart device or a monitor.

Some receivers come with built-in storage with the microSD card, while others need to establish a DVR connection. The complete process goes as follows:

Step 1. Image of motion detection

Like any digital video camera, a WiFi spy camera creates images and videos after checking the light passing through the lens.

The same lens depends on many light detectors that work differently in black & white and colored Wi-Fi spy cameras.

In the case of a Black and white wifi spy camera, the detectors will measure the amount of light falling on a specific part of the image.

On the other hand, when a colored Wi-Fi spy camera is used, the detectors will only gauge the red, blue, and green lights entering the lens.

Afterward, the identical detectors will display a specific light color on the image. This then helps the Wi-Fi spy camera create the image.

The motion detectors work similarly while gauging any random light passing through the camera lens and sending alerts to the receiver.

Step 2. Image or video transmission

Most WiFi spy cameras come with pre-fixed mini radio transmitters that help them transmit the image or video to the receiver.

The camera first converts the image into a radio signal at a specific frequency and transmits it to the receiver, placed at a distance.

The receivers then pick the signal and convert it back to an image. Due to their smaller size, the receiver can transmit signals to a shorter distance.

Step 3. Displaying the image or video on the smart device

Once received, there is a lot that a receiver can do with the transmitted image.

The smart device will display the receiver’s image or video if the Wi-Fi spy camera is positioned at a specific location for constant surveillance.

In most cases, the receiver saves random frames per second to create a time-lapse image of the area under surveillance.

So, you can view the image or the video and save it to a hard drive, cloud, or any other preferred storage option.

Certain WiFi spy camera manufacturers offer high-end features like two-way audio, night vision, and 1080P HD video recording with their WiFi spy cameras.

Bottomline for how do Wi-Fi spy cameras work

A standard Wi-Fi spy camera is just the mini-version of a high-end Wi-Fi security camera. Hence, the functioning process ( barring a few aspects) of both is similar.

Still, a Wi-Fi spy camera is easy to hide, and this is where it best serves the requirement of people looking to monitor their surroundings without letting them know the subject in focus.
