Pennsylvania Surveillance Investigations: Laws and Guidelines

Legal Framework for Private Investigators
in Pennsylvania

In Pennsylvania , private investigators (PIs) are governed by some of the nation’s strictest surveillance laws. The key statutes include the Private Detective Act of 1953
and the Wiretap and Electronic Surveillance Control Act. These laws establish clear boundaries for surveillance activities.

Audio Surveillance
(Strict Two-Party Consent)

The Commonwealth of Pennsylvania is a two-party (or all-party) consent state concerning audio recordings. This means that, for an audio recording to be lawful, all individuals involved in the conversation must provide their consent beforehand.

  • Recording Rule: Recording any oral communication without the prior consent of all participants is a third-degree felony.
  • Admissibility: Audio that has been secretly recorded is generally inadmissible in Pennsylvania courts. Such actions can lead to both criminal charges and civil lawsuits.
  • Public Exception: Recordings may be permitted in public spaces where individuals have no "reasonable expectation of privacy," such as during a loud argument in a public park.

Video Surveillance

  • Public Areas: Private investigators are allowed to record video in public locations where there is no expectation of privacy, such as sidewalks, parks, or parking lots.
  • Prohibited Areas: It is illegal to conduct video surveillance in private areas like bathrooms or dressing rooms, or anywhere an individual reasonably expects privacy.
  • Silent Video: Due to Pennsylvania's strict audio recording laws, most professional surveillance is performed using video only. Even accidental audio capture can result in felony charges.

GPS Tracking and Electronic Devices

  • Consent Required: Private investigators must generally obtain the owner's consent before placing a GPS tracking device on a vehicle.
  • Recent Legislation: As of 2025–2026, new laws further criminalize unauthorized electronic tracking. Installing a tracking device on another person's property or on their person without consent is usually classified as a misdemeanor.
  • Exceptions: Law enforcement may use tracking devices with a court order, but private citizens, including private investigators, are not afforded this privilege.

Trespassing and Physical Access

  • Private Property: Private investigators do not have special rights to enter private property. They are subject to the same criminal trespass laws as all other citizens.
  • "Plain View" Rule: Investigators may observe or photograph anything visible from a public location. However, using enhanced equipment, such as drones or high-powered lenses, to see into a private home can be considered an invasion of privacy.
  • Mail and Records: Accessing another person’s mail or private bank and phone records without a court order or the owner’s permission is strictly forbidden.
