Hidden Camera : What is it?
| Hidden cameras are used to film events without the knowledge of the subjects. They are commonly used in surveillance and law enforcement to catch suspects in criminal acts. They transmit recorded video or still images to computers, television screens, or other display devices. Some types record them onto videotapes or internal memory for later viewing. Hidden cameras are usually lodged into walls or corners, or disguised as common items such as clocks, paintings, signs, and speakers. |

Kinds of Hidden Cameras include the following: |
Nanny cameras
- Nanny cameras are used to monitor activities in the home when the owners are away, such as when children are left with nannies.

Recording time: Choose a hidden camera that can record for extended hours without running out of power or recording medium. Look for one with expandable or removable memory so that you can add more storage when necessary. Make sure it can switch between battery and AC power to provide a backup in case of power failures.
Frame rate: Choose a hidden camera with a high frame rate. Slow frame rates may not properly capture quick actions and may blur when slowed down. Look for frame rates of about 30 frames per second. |
