4 Simple Steps to Build Spy Camera from Your Old Phone

Let’s look at four easy to follow steps to make a spy camera out of your old smartphone:

1. Adjust Your Mobile Phone

The first thing you need to do is find yourself a mobile phone that is not in use but works properly. Get a stand for your mobile to mount it. You can also use a tablet if you don’t have an old mobile phone. Connect a charging cable to your mobile if you want to record 24/7. 

2. Hide Phone

You will need to modify your mobile if required. Make sure to find a place to hide it where no one could see it. You can hide the mobile either in a book or in a videotape box. Find a way that it does not look conspicuous. 

It is essential to take care of the camera if it is visible for recording. Furthermore, ensuring the place you decide to place the mobile phone is good to film a clear line of view for perfect video of evidence. 

3. Download Software

Here comes the most crucial step. Now to turn your old mobile into a spy camera for real, you will need to download some security software. You can download one of these two: hidden spy camera detectors, Salient eye, or any other app for monitoring. However, it is essential to ensure that the software is compatible with your mobile phone model.

4. Testing

Lastly, don’t forget to test your camera before finalizing everything. When it was my first time, I didn’t try my camera and software compatibility before recording due to excitement and wasted the window of time for collecting the evidence. 

Because the software I downloaded was not working, but the apps I’ve mentioned are worth it to download, or you can find others on the internet for yourself. So, always remember to test the software before you start recording. (1)

Why Should You Use a Spy Camera?

Spy cameras are no longer rare because of recent advancements and developments. If you already have security cameras and you think that is enough, you’re mistaken. 

If you are a sibling or a parent, it is a must to keep your eye on them even when you are not home. With a spy camera, you would be able to see them every moment and you know what the best part is? They won’t even know it.

Moreover, if you stay in a hotel, you don’t need to worry about your valuables disappearing when you are not in the room. You could monitor every person who enters your room. Even if anything ‘magically disappears,’ you would know.

How Is Spy Camera Beneficial For You?

When you make a spy camera out of your old mobile phone, you find some big benefits.

Here are the top benefits of using a spy camera:

Become Hero Of The Day

We might get stuck in a situation where a crime is unwrapping right in front of our eyes, but we don’t have any proof to bring that criminal to justice. 

Investigative Journalism

In this world of scams, journalism is consistently getting better with eye witness reports. This tiny hidden camera will help you record facts.

Watch Over House Helpers

If you know about a maid or babysitter who is not performing the job honestly, you can record a piece of evidence to fire him/her. (2)


Spy cameras are allowed by the government to use at different corners of the house. However, there are some areas where you are restricted to hide the spy cameras, i.e. bedrooms, bathrooms, and other rooms where people expect privacy. Here’s how to find hidden spy camera.

How long can you record with a spy camera? 

If you purchase a spy camera from the local store, it could be workable for a few weeks. However, a spy camera created with a mobile phone can work 24/7, but it would need a charging cable.

What is the difference between a spy and hidden cameras? 

You can take spy cameras anywhere with you whereas a hidden camera is used to fix somewhere that no one can see. Moreover, both cameras are not used to get dirt on anyone but for security purposes.

The Bottomline

Recording different activities happening in your surroundings is an additional fun element but practicing ethical and moral boundaries is necessary.

Moreover, your recording might help identify any suspicious activity of a person on the streets or catch the thief red-handed from your area.

That’s all for today. I hope this helped you build a spy camera from your mobile phone and allows you to reap its benefits. If you have any questions, feel free to contact us!
