Look for a built-in microphone, which is like a small hole on any side of the camera.

Search about your camera directly on the web and know if it has an audio-enabled feature.

If you are trying to find the perfect home security system or commercial CCTV camera system in the United States or Singapore, read through the detailed terms below before making a purchase.

Audio Recording CCTV Camera Laws In The United States

The legality of audio recording through CCTV systems is governed by federal and state laws in the United States and may vary significantly between jurisdictions. Here are some key points to consider-

Federal Law

Audio recording is generally permissible under federal law if at least one party (either the person conducting the recording or the person being recorded) gives consent. This is known as “one-party consent.”

State Laws

Some states require consent from all the parties involved in the recording, known as “two-party consent.” States such as California, Florida, and Pennsylvania have specific laws mandating two-party consent for audio recordings.

Public vs. Private Spaces

Privacy laws also differentiate between public and private spaces. In public spaces where individuals do not have a reasonable expectation of privacy (e.g., streets, parks), audio recording may be more permissible. However, in private spaces such as homes, workplaces, or areas where privacy is expected (e.g., restrooms), stricter consent requirements typically apply.

Violating audio recording laws can lead to legal consequences, including civil liabilities and criminal charges, depending on the severity and context of the violation.

Audio Recording CCTV Camera Laws in Singapore

In Singapore, the regulations regarding audio recording through CCTV systems are guided by the Personal Data Protection Act (PDPA) and other relevant legislation:

Consent Requirement

Generally, consent from at least one party involved in the conversation is required for the audio recording to be lawful. This aligns with Singapore’s approach to “one-party consent.”


Organizations and individuals must inform individuals when audio recording is taking place. Signs or notices indicating the presence of CCTV cameras with audio recording capabilities are often required in public and private spaces.

Data Protection

The PDPA mandates that personal data, including audio recordings, must be handled responsibly and securely. This includes ensuring that recordings are used only for legitimate purposes and are protected against unauthorized access or disclosure.

The Personal Data Protection Commission (PDPC) of Singapore can take legal action against individuals who do not comply with the PDPA.

Every individual or organization installing a CCTV camera system at their home or commercial premises must comply with the relevant laws in order to guarantee the security and confidentiality of their personal space.

Things To Consider Before Purchasing An Audio Enabled Security System

Although cameras with audio recording help enhance the overall security and offer ample benefits, there are some potential drawbacks. Consumers face several issues, which major one being the legal issues associated with it. Using a CCTV system with audio recorders often:
