Wi-Fi spy cameras work just like any other Wi-Fi security camera. The most significant differences are 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 duplicate footage or recordings 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.

How Do Wifi Spy Cameras Work – What are Wifi Spy Cameras?
Understanding the process regarding how Wi-Fi spy cameras work
A Wi-Fi spy camera boasts a wireless RF (radio frequency) 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 by detecting the light passing through its lens.
The same lens depends on many light detectors, which work differently in black-and-white and colored Wi-Fi spy cameras.
In the case of a black-and-white Wi-Fi spy camera, the detectors measure the amount of light falling on a specific part of the image.
Conversely, when a colored Wi-Fi spy camera is used, the detectors only detect the red, blue, and green lights entering the lens.
Afterward, the identical detectors will display a specific light color on the image, which helps the Wi-Fi spy camera create the image.
The motion detectors work similarly. They gauge any random light passing through the camera lens and send 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 up the signal and convert it to an image. Due to their smaller size, receivers 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 in 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.
You can view the image or video and save it to a hard drive, cloud, or 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.
