Cedar Hill, TX Privacy & Surveillance: Security Camera Rules (2026)

Dallas County does not have a county-specific ordinance regulating residential security cameras. Texas state law governs surveillance throughout the county's jurisdictions. Homeowners may install security cameras anywhere on their own property without a permit — this includes mounting cameras on exterior walls, fences, sheds, garages, and in yards. The key legal standard is reasonable expectation of privacy: cameras must not be deliberately aimed at areas where people expect privacy (neighbor's bedrooms, bathrooms, enclosed backyards). Texas Penal Code §16.02 prohibits unauthorized interception of oral, wire, or electronic communications. For video-only recording without audio in public or semi-public areas, there are minimal restrictions. If cameras capture audio, Texas's one-party consent law applies — at least one party to the conversation must consent. This means homeowners can record conversations at their own door but should not capture neighbors' private conversations. The City of Dallas and other municipalities encourage residential security cameras as part of crime prevention. Some neighborhoods participate in police-community camera sharing programs. Commercial security camera installations for others require a Texas Private Security Bureau license.
