Like any surveillance device, hidden or mini cameras get their power from a number of different sources, including USB cables and hardwiring.
Read on and find out the different ways hidden cameras are powered.

Types of Power Source
1. USB
Much like regular-sized security cameras, a common way of powering a hidden camera is through a USB cable.
These are convenient since USB’s are found here, there, and everywhere, and it usually means that a device can be bought from any region in the world without the buyer having to worry about incompatible plug types.
Pros
- Universal
- Easily replaced
Cons
- 24/7 surveillance may require it being left plugged in constantly
- Not especially covert, unless the hidden camera is disguised as a USB stick
2. Hardwiring
A hidden camera that has been constructed from scratch (i.e. isn’t available commercially) to hide in a specific object may be hardwired to take advantage of existing electrical wiring.
In our article discussing bug placement, we noted that smoke alarms are a hotspot for bugging, because the hidden device can use the hardwiring powering the alarm while remaining totally concealed.
Pros
- Constant power source
- Can be extremely discreet
Cons
- Complex process
- Bugging is illegal, so if it is totally concealed, laws may be compromised
3. Cigarette Lighter Socket
In our guide to mini and hidden cameras, we pointed out that dash cams are a strong alternative for people looking for discreet surveillance solutions.
Many ‘hidden camera’ products are essentially gimmicks that cannot be used as an authentic security solution. Car-based surveillance, hidden or otherwise, will usually be charged by the cigarette lighter socket.
Pros
- Easy way to power dash cams
- Constant source of power when car is on
Cons
- Vehicle-only solution
- If the device doesn’t retain a long charge, may require the car being on to work
If driving is your profession, it’s important to know what you can and can’t do in terms of vehicle security. Uber drivers, taxi drivers, and chauffeurs: head here for the best hidden cameras for cars.
Disposable battery hidden cameras?
While it’s possible to find ‘spy cameras’ with disposable batteries on Amazon and elsewhere, disposable batteries can be considered a clear sign that a product is designed as a toy or gimmick as opposed to a meaningful security solution.
It’s advisable to avoid such products if wanting, for instance, subtle security for the inside of a car.
FAQ
Do hidden cameras need power?
Yes, hidden cameras need a power source. Hidden cameras are usually powered by a USB charging cable or disposable batteries.
How long do batteries last in hidden cameras?
Hidden cameras are small in size, meaning the batteries powering them are also small. Most will need to be charging constantly to record for extended periods.
Can hidden cameras work without WiFi?
Some hidden cameras can work without Wi-Fi. Often, they will have a microSD card slot to allow for saving footage to local storage.
Do wireless security cameras need to be plugged in?
‘Wireless’ security cameras refers to devices with wireless technologies, like Wi-Fi or 4G data. It isn’t the same as being totally ‘wire-free’. Hence, wireless security cameras may need to be plugged in to record or at least be plugged in for a few hours to charge.
Conclusion
USB’s are the most common and most reliable way that hidden cameras are powered, while devices powered by disposable batteries should probably be avoided if looking for a legitimate surveillance solution.
