Step by Step Instructions

People can save some money by performing the following steps. Once all the right items have been gathered, it will be very easy to make a wireless spy camera.


1. Working with the smartphone


a hand holding a device and a mini cameraFirst of all, it is necessary to remove the camera located inside the phone. To do this, open the phone and work with the built-in green plate. At the top, we can see how the camera is connected to the green plate. Using a voltmeter, measure the values indicated on each of the camera ends.

Then simply remove the camera and the material attached to it. Using a sharp object it is necessary to remove part of the brown layer incorporated in this plate. The flash must also be removed as it is not the object we need to use. Once the camera has been removed it is possible to continue with the next step.

2. Incorporate connections


Using a small soldering iron some small wires must be incorporated to make the connection with a micro USB cable. We are trying to establish a connection through the wires incorporated with the solder. This will allow connecting the camera removed from a phone to a USB cable.

It is recommended that all people using soldering have some experience, although the job is relatively simple. Each wire needs to be incorporated into the connectivity part of the camera.

3. Connect with USB cable

You can also use this same type of cable for the entire camera itself. We can obtain a USB cable with a spy camera at one end. The user has the choice between a USB cable or a micro USB cable. The most recommended is a micro USB cable to be able to use this spy camera with a smartphone. 

After choosing the right cable, the length should also be considered. A cable that is too short may not be useful or practical depending on the needs of each user. A cable with the right length allows making a spy camera that is more difficult to detect. 

4. Download the app

It is necessary to download the application with the specific functions according to the needs of each user. Free applications are usually the most basic, and in some cases, essential functions such as video recording are not incorporated.


6. Test the camera

Final words

There may be some problems related to the camera when we cannot see the image. In case there is any kind of issue we should check if we have made correctly the connections of the camera with the micro USB cable or USB cable. Some connections may be inadequate. 

People may also avoid using the thermoplastic cable due to a lack of knowledge of its existence. When this cable is not incorporated the connections are much more exposed which means a shorter lifespan of the device we have created, and if you are not into making one, then you can just buy and read further this guide on how to set up a spy camera. Until next time!
