Lately, someone has been sneaking around and stealing your belongings, but you have no way to prove it. Whether the culprit is a friend, family member, colleague, or even your sworn enemy, a hidden camera can help you gather the necessary evidence to confront them and put an end to their shady behavior.
Steps
Hide the webcam inside everyday objects

Purchase an inexpensive webcam. There are cameras suitable for this purpose that cost less than 200,000 VND. You can search online for “affordable webcams.”
- Opt for a basic and compact webcam. The camera needs to be small to avoid detection. You can hide it in items like a pencil sharpener or a tissue box; keep this in mind when selecting your camera.
- If you need to set up the camera as soon as possible, you can visit large electronics stores and ask for the smallest and cheapest model available.
- If you’re aiming to catch someone committing a serious offense, consider investing in a professional surveillance camera. DIY hidden cameras can work in a pinch, but the image quality will be significantly better with a higher-end device.

Remove the outer casing of the webcam. You’ll see the circuit board with the lens attached. This makes the camera much more compact and easier to conceal.

Choose a hiding spot for the camera. Get creative! The camera will be less likely to be detected if hidden in an everyday object. Use something that you normally keep in your room or office; an out-of-place item might raise suspicions.
- For example, you could use an unused electric pencil sharpener, remove its internal components, and position the camera lens through the sharpener hole. Just disassemble the sharpener, remove the motor and wires, and ensure it’s not plugged in!
- Try using a shoebox or a cardboard tissue box. Cut a small hole in the box so the camera can “see” through it. Avoid making the hole too large, as you don’t want to arouse suspicion.
- Consider using a shopping bag or gift bag. Similarly, cut a small hole inside the bag. If the bag has patterns or textures, the hole will be less noticeable, especially if the bag is black or dark-colored.
- Think about hiding the camera in the foliage of a potted plant or deep within the nooks of a bookshelf – anywhere that draws little attention. Ensure the lens is pointed toward the area you want to monitor.

Install the camera inside the object. Position the lens to face the opening in the item, ensuring the camera fits snugly inside and doesn’t look suspicious.
- If you’re worried about the object being moved, use multipurpose glue to secure the camera in place. Glue the edges of the lens so it stays aligned with the opening. Be careful not to get glue on the lens – it can blur the image and is hard to remove.

Use glue or fishing weights inside the object to prevent it from being suspiciously light. This is crucial if you’re hiding the camera in devices like pencil sharpeners, clocks, or similar items – these are typically heavier.
- If you don’t have fishing weights, you can substitute them with a flat piece of metal. Be cautious when handling sharp or jagged metal objects.

Thread the USB cable (connecting the webcam to the computer) out the back of the hiding object. You may need to place the camera near the computer if the cable isn’t very long.
- Use something to conceal the USB cable. A jacket or piece of paper can work, but it might not look natural. If the “pencil sharpener” is visibly connected to a computer, it could raise suspicions.

If the camera is hidden inside a device, you can label it as “Out of Order” to prevent others from touching it. If someone tries to use the device, they might discover the camera.
- However, keep in mind that an “Out of Order” sign might draw attention. People are less likely to notice the “device” if you don’t label it – especially if it’s placed in a discreet location.

Position the camera toward the area you want to monitor. Imagine you’re a film director setting up a shot: think about what you want to prove with the footage and whether capturing the culprit’s face is important.
- If you simply want to stop someone from entering your private space – like a sibling sneaking into your room – aim the camera at the door to capture them entering.
- If you’re dealing with a specific behavior, such as a sibling taking your clothes or a coworker stealing office supplies without permission, point the camera toward the items to observe their actions.
- If you want to catch multiple suspicious activities, place the camera further away to capture a wider view of the room. Consider installing two cameras in different locations.
Use a smartphone as a camera

Find a smartphone. Any Android, iPhone, or old iPod with internet connectivity will work – essentially, any device that can run apps and access the internet.
- Remember that the phone will serve as the camera, so you can’t use it for other purposes while recording. It’s best to use a phone you don’t frequently use; you can borrow an old phone from a friend or buy one from a second-hand store.
- Ensure you have a phone charger. Continuous recording drains the battery quickly, so you’ll need to keep it charged.

Download a free webcam app. You can find a suitable program on your phone through the App Store or Google Play Store by searching for “webcam app.”
- Look for apps like Webcam, MobileWebCam, DroidCam, or iCam. Read reviews before downloading to ensure the app is safe and reliable.
- Many apps are free, with developers earning revenue through ads. You don’t need to spend money on expensive apps; a free program will suffice.
- You’ll need to grant the webcam app full control over the camera, meaning no other apps can use the camera while the webcam app is running. This won’t harm your phone or its camera.

Remember the URL of the webcam app. You’ll need this to connect your phone to the computer.

Connect your phone to the computer. Ensure both devices are on the same wireless network. This allows you to monitor and record remotely. Use any compatible video player, such as VLC or Windows Media Player.
- If using VLC, click "Open Network Stream" under the "Media" menu and enter the URL displayed on your phone’s webcam app. Inputting the URL will connect you to the phone’s camera.
- Free programs like VLC and Windows Media Player are great for viewing webcam footage on your computer, but they don’t support high-quality recording. For serious surveillance, consider investing in more advanced webcam software.

Set up the camera. The phone will need to stay near its charger, so plan accordingly. Position the lens toward the area you want to monitor and ensure the phone is stable and won’t tip over.
- You can prop the phone against a wall or a stack of books. Place it horizontally to reduce the risk of it falling.
- Consider hiding the phone inside an object. Refer to the “Hide the webcam inside everyday objects” section for ideas.
- Turn off ringtones and vibration, especially if your phone can receive calls and messages. An unexpected sound could ruin your entire plan.

Secure your network. Set up a protected wireless network with a strong password. If you use an unsecured or public network, anyone on the network could access your footage.
- Ask your internet service provider about secure network options. If you’re paying for wireless internet, you can set a password for your router.

View the footage on your computer. If you need to leave home, you can connect to public wifi at a café, restaurant, or library.
Recording Footage

Be mindful of the law. In the U.S., you can generally use a hidden camera to record someone without their consent – as long as you’re filming in a public space or your own private property. Many states have laws prohibiting recording in places where individuals have a reasonable expectation of privacy, such as bathrooms or private bedrooms.
- Typically, installing hidden cameras in the workplace is legal if it’s work-related. Avoid secretly recording others to resolve personal conflicts – unless you’re prepared to face potential legal consequences.
- Laws vary by country and region. Check local regulations before recording audio or video of anyone without their permission.
- If you plan to distribute, sell, or use the footage in court, adhering to the law is crucial. If the footage is for personal use only, you don’t need to worry as much.

Download a webcam recording program. Search for “free webcam recording software” and install it on your computer.
- You can use Windows Movie Maker or iVideo if these programs are already installed on your computer. Check the Start menu (bottom-left corner of the Windows screen) to see if the program is available.

Plug the USB cable into your computer. When you leave the room or are ready to start recording, launch the recording software and click "Record."
- Use something to conceal the USB cable so the hidden camera isn’t exposed. Books, papers, or a jacket can work – anything that looks ordinary.

If you already have a webcam, you might only need to use your existing camera to record. Be discreet; only use this method if you usually keep the webcam near your computer.
- Remember that while this is the simplest method, the other person might become suspicious if they notice the camera pointing at them – even if they don’t think it’s recording.
- Make sure to turn off, cover, or disable the LED light that indicates the webcam is active. A “recording” light could alert the person that they’re being filmed.

Remember to turn off the screen. If the screen is on and the other person sees the webcam footage, they’ll know they’re being monitored. To expose someone’s sneaky behavior, you need to act discreetly.
- If you’re using a desktop, you can turn off the monitor while keeping the computer running.
- If you’re using a laptop, you can put the screen to sleep while the recording program runs, or consider closing the lid almost completely – but not entirely. The computer will appear inactive but will still be running.

Continue recording until you capture the footage you need. Let the camera run during the times you suspect the necessary evidence will be captured. If unsure, keep the camera active as often as possible.
- If you still haven’t captured any incriminating footage, reassess the situation. Is the thief only doing this once? Or have they found a way to avoid your camera?
Presenting the Evidence

Use video editing software to trim the footage into usable evidence. Your computer may already have default programs like Windows Movie Maker or iVideo; if not, you can download free video editing software online.
- Ensure the footage clearly shows what you need to prove your suspicions. Whether it’s catching a sibling taking your belongings or a coworker stealing office supplies, the clip should start a few seconds before the action and end a few seconds after.
- Save the relevant footage as a new video file, but don’t delete the extra clips right away. Sometimes evidence lies in unexpected places. You might find something valuable when reviewing the unused footage.

Save a backup copy of the footage in a separate folder. If you plan to use the video as legal evidence, it’s crucial to protect it.
- Consider emailing a copy to yourself. Even if someone deletes the footage from your computer, you’ll still have a copy to download from any internet-connected device.
- For the same reason, consider saving the footage on a USB drive and storing it in a secure location.

Confront the thief. Be tactful. Let them know you’re aware they’ve been stealing your belongings and ask them to stop.
- You don’t need to reveal the footage immediately. It might be useful later if they continue the behavior after being warned. If they admit to their actions when confronted, you won’t need to present the evidence.
- If the person discovers you have a hidden camera and knows its location, they might try to avoid it. Don’t reveal your trump card too soon.

Forgive, but don’t forget. Some people don’t learn their lesson after being caught the first time. Be aware that certain individuals might continue their sneaky behavior even after being exposed once.
- Consider keeping the camera in use if you suspect the person might repeat their actions. It’s better to be safe than sorry.
- If the issue persists, report it to someone in authority. If it’s a sibling, tell your parents. If it’s a coworker, inform your manager. If it’s a criminal, contact the police.
Tips
- Disable the LED light if your camera has one that lights up during recording.
- If your camera includes audio recording, cut a small hole in the hiding object below the “Out of Order” sign and secure it with glue.
- If you have a Macintosh, download the Macam program from http://webcam-osx.sourceforge.net/. This program is excellent as it supports both video recording and photo capture. Many webcams aren’t compatible with Macintosh computers.
Warnings
- When presenting evidence, only tell your parents and siblings that you placed a regular camera in the room. Don’t reveal your secret weapon.
- Be aware that recording someone in private spaces like bathrooms or bedrooms is illegal.
