Legality of Hidden Cameras

The laws on hidden video cameras differ from state to state.  If you're currently considering installing or are using a hidden video camera system, it would be prudent to investigate the specific laws of your state to ensure that you don't run into any legal problems should anyone discover and take offense to the fact you're operating a covert video surveillance system.

At the time of this writing, there are only thirteen states which have any laws prohibiting the installation and/or operation of hidden cameras.  The laws that govern these specific states only expressly prohibit the installation of hidden surveillance equipment in those places where individuals have the right to a reasonable expectation of privacy, such as bathrooms, locker rooms, dressing rooms, bedrooms, etc.

In fact, if a crime is captured on tape by a hidden camera, in many states, the video is admissible as evidence in court.  In quite a number of states, consent from the parties being filmed isn't even necessary; while in a number of others, receiving the consent of only one party is required.

Due to the lack of uniform or strict laws governing the installation and use of hidden video surveillance equipment, it would be wise to consult with "local" law enforcement to be certain of the specific regulations governing your area and to ensure that you have a clear understanding of the laws.

In order to avoid any costly legal actions in the future, it's definitely better to find out ahead of time what you can or can't do legally in your state when installing a covert camera surveillance system.
