A spy pen camera works exactly like a standard spy camera, with its size, shape, and positioning as the only difference.
It’s tiny yet powerful and efficient enough to shoot decent videos and photos per your needs and preference.
The overall mechanism and functionality of a spy pen camera depends on its type, build, and quality. Still, most spy pen cameras follow a standard procedure regarding the detection, recording, and transmission of videos captured.
Understanding the functionality of Spy pen cameras
The spy pen camera’s functionality process varies according to the size, shape, and model purchased from the market. Still, if it’s a wifi spy pen camera, it will transmit the video and audio signals to a smartphone or a PC.
The footage can then be stored and used according to the user’s needs and requirements.
On the other side, a spy pen camera without wifi feature stores the video and audio footage within the inbuilt microSD card, instead of communicating it to a smart device.
Step 1. Detecting the images or motion
The spy pen camera detects the images or motion within their surroundings after tracking through the camera lens’s light crossing.
The spy pen camera lens includes several light detectors that work according to the type and quality of light passing through.
The process goes different in terms of Black & white spy pen camera. While the light detectors in colored spy pen cameras check on red, blue, or green lights, the black and white ones check on the light falling on a specific part or zone in the camera lens.
This way, the lens will form an image after detecting the required colors. If your spy pen camera is facilitated with a motion detection feature, it will further track and monitor any random light or motion passing through the camera lens.
This motion detection then triggers the spy pen camera to send alerts to the receiver, which further transmits them to a connected smart device or app.
Step 2. Transmitting the image or video to a receiver
The same image is then transmitted to the receiver via inbuilt mini radio transmitters in these spy pen cameras. Spy pen camera comes in different configurations. Still, the ones with single-button controls are most popular.
All you need to do is make a single click to the end of the spy pen, and it will start the recording process after getting powered on. The button can also be used to pause the video recording, and holding it for a bit more time will power off the device.
Some of the spy pen cameras come with built-in memory, while others require memory cards to be inserted into the provided slots.
Bigger memory allows you to record longer videos and vice versa.
So, once the camera converts the image formed by lenses into a radio signal, it then transmits the same to the receiver, which further transmits it to a smart device placed at a distance.
In case the spy pen camera doesn’t have wifi connectivity, it will store the videos and images in inbuilt memory that can then be extracted via a card reader or USB.
Step 3. Transmitting the video to a Smart device
Once the receiver receives the image or video, it can then be broadcasted or displayed on a smart device.
Now, it all depends on the type and quality of Spy pen camera you are using, and several high-quality spy pen cam offers 1080p full HD resolution.
So, you can view all those images or videos in real-time.
If you are using a spy pen camera without wifi connectivity, you have to wait to view the images or videos, until it gets connected to a smart device or a card reader.
The video or image can be stored in the cloud, hard drive, or any other preferred storage option or device.
Bottom-line for how does a spy pen camera work
A spy pen camera works perfectly in situations where you need to spy on your subject on the move. Besides being compact, these spy cameras are compelling and efficient in their video quality and related features.
Still, one must check on the provided guidelines and laws within their state, city, or country regarding the usage of video surveillance devices.
