Buying Guide for Hidden Cameras

Finding a hidden camera that meets your budget and needs can be difficult. To ensure that you’re making an informed purchase, here are a few factors to consider. 

Video Quality/Resolution

Resolution is a measurement of the total number of pixels a camera records per frame. The image should be clear enough to see details of what’s happening both during the day and at night. The most common resolution for hidden cameras is 1,080 pixels. However, some models offer 1,440, 1,920, or 2,160 pixels. 

Installation

Hidden cameras either plug into a wall outlet or run on a rechargeable battery. With a cord, your hidden camera gets constant power. However, you can only install it where there’s an outlet. Wireless cameras offer versatility in terms of placement, but there will be a few hours at a time when it’s not recording because it’s charging.

Battery Life

Hidden cameras that have rechargeable batteries may last up to 20 hours or more before they need to be recharged. Some models only have a battery life of a few hours. To help conserve the battery, hidden cameras generally go on standby if the unit has a motion-activated camera. When motion is detected, the camera will start recording.

Control

Most hidden cameras connect to your smartphone so you can pull up the app and check on your home when you’re away. Others connect to voice assistants, such as Amazon Alexa, as well as smartphones, tablets, and computers.

Capabilities

If your hidden camera connects to your smartphone, it likely has other smart features. Below are a few of the most common hidden camera capabilities.

  • Two-way audio
  • Motion detection
  • Night vision
  • Push notifications

Frequently Asked Questions About Hidden Cameras

Is it legal to record someone without their consent?

In most states, it’s legal to record audio-free videos of your home. However, laws may vary depending on your location and the subject’s age. For example, you can’t record a child using the restroom. We recommend reading up on your local government’s privacy laws before you purchase a hidden camera. If you’re still unsure of its legality, you can contact a local official to have them explain the laws.

What is the purpose of a nanny cam?

The purpose of a nanny cam is to keep a close watch on your children while you’re away from home. Many parents use them to ensure their caretaker isn’t mistreating their kids.

Can hidden cameras be hacked?

Yes, hidden cameras can be hacked. Hackers can get into Wi-Fi-enabled devices, such as smart hidden cameras. To minimize the risk of hacking, connect your camera to a secure and private Wi-Fi network.
