The camera is usually attached to the green-colored plate that is built into any smartphone or laptop. It is best to have an Android smartphone as it is very simple to remove the camera. 

To remove this camera, few tools are required. The user must remove the camera along with the built-in connector. The rest of the smartphone or laptop can be discarded as we only need to remove the camera.

2. Connect the camera with the USB cable

The next step that the user needs to do is connect the camera and a USB cable. Take a USB cable and cut off the connector end of the USB cable. Leave a certain length of the cable according to the needs of each user.

Remove the outer part of the cable to be able to work with the four inner cables. Once the main sheath is removed, the sheath of each of the four wires inside the USB cable must also be removed.

Using solder, permanently connect the metal part of each of the four wires inside the USB cable to the mini camera connector. All four terminations of the USB cable must be properly connected to the mini camera connector.

3. Attaching the OTG cable

This cable is one of the necessary pieces to use the mini camera with a smart device such as a cell phone. The OTG cable provides a female input for connecting the USB cable and a male connection as a mini-USB cable. (2)

A suitable cable can be obtained to connect the mini camera with a smartphone. In using the mini camera with a laptop, it is not necessary to incorporate the OTG cable. Simply connecting the first USB cable to a laptop will be sufficient to establish the connection.

4. Incorporating the software

Incorporating an application to use this mini camera is one of the necessary steps if we are going to use this device on a smartphone. We need an application that allows the use of a camera that is connected through a USB cable.

When it comes to using the mini camera on a laptop, it is unnecessary to implement any special software. Only the new camera should be configured as a device in use.

Some more recommended apps for Android devices are the following.

  • TinyCAM Monitor
  • IP Cam Viewer Pro
  • ONVIF IP Camera Monitor (Onvifer)

All of them present different features but are suitable to get good use of the mini camera we have created.

5. Testing the camera

Testing the camera is the last step to check that we have done a good job. On a smartphone, open the application and connect the micro-USB input with the mini camera. 

We will be able to check that the mini camera is working properly and without problems. Cleaning the front of the lens is a good way to ensure that we get a safe and reliable operation.
