New Hampshire Security Camera Laws

In New Hampshire, silent video security cameras are generally legal on your own property, but cameras that record audio require all-party consent under RSA 570-A:2. RSA 644:9 bars cameras from bathrooms, bedrooms, and other private spaces regardless of audio capability.

Security cameras are a standard part of modern life in New Hampshire, installed in homes, businesses, government buildings, and public spaces. However, the Granite State's strict all-party consent wiretapping law creates important legal considerations that security camera owners must understand. The legality of any particular camera installation depends largely on two factors: whether the camera records audio, and where it is placed.

This guide covers the legal framework for security cameras in New Hampshire, including residential systems, business surveillance, audio recording restrictions, privacy limitations, and best practices for compliance.

The Legal Framework for Security Cameras

Two Statutes That Apply

Security camera legality in New Hampshire is governed by two primary statutes:

RSA 570-A:2 (Wiretapping and Eavesdropping): This statute prohibits the interception of telecommunications, oral communications, and electronic communications without all-party consent. It applies to security cameras that record audio. If your camera captures conversations, the all-party consent requirement is triggered.

RSA 644:9 (Violation of Privacy): This statute prohibits installing recording devices in private places such as bathrooms, bedrooms, and changing rooms. It applies to all cameras regardless of whether they record audio.

Together, these statutes create a framework where the audio capability and placement of a security camera determine whether it is legal.

Silent Cameras vs. Audio-Enabled Cameras

The critical distinction is audio. A silent security camera in a retail store captures video of customers but does not intercept their conversations. This is generally lawful. The same camera with a microphone enabled captures oral communications and triggers the wiretapping statute.

Residential Security Cameras

Exterior Cameras

New Hampshire homeowners may install exterior security cameras on their own property. Common legal placements include:

• Front door and doorbell cameras (Ring, Nest, Arlo, etc.)
• Driveway cameras monitoring vehicle access
• Backyard cameras pointed at your own property
• Garage and shed cameras for security purposes

Audio considerations: Many modern doorbell cameras and outdoor security cameras have built-in microphones. If these devices capture conversations between visitors, neighbors, delivery workers, or passersby, the audio component may trigger the all-party consent requirement under RSA 570-A:2. The key question is whether the recorded individuals had a reasonable expectation of privacy in their conversations.

Conversations on your front porch between visitors who know a camera is present likely carry less expectation of privacy than a quiet conversation between neighbors at a property line who do not realize they are being recorded.

Best practices for exterior cameras:

• Consider disabling audio recording on exterior cameras to avoid wiretapping concerns
• Post visible signs indicating that video and/or audio recording is in progress
• Point cameras primarily at your own property rather than neighbors' homes or public sidewalks
• Review footage periodically and delete recordings you do not need

Interior Cameras

Homeowners may install interior security cameras with these limitations:

• Common areas (living rooms, kitchens, hallways) are generally permissible for silent video
• Bathrooms, bedrooms, and changing areas are off-limits under RSA 644:9, even in your own home when guests or household members have a reasonable expectation of privacy
• Audio-enabled interior cameras capture household conversations and may violate RSA 570-A:2 if occupants or visitors are not informed and do not consent
• Nanny cams are generally legal for silent video in common areas, but audio-enabled nanny cams raise consent issues

Neighbor Disputes

Security cameras can create friction between neighbors. In New Hampshire:

• You may point cameras at your own property, even if they incidentally capture a portion of a neighbor's property
• Deliberately aiming cameras at a neighbor's windows, backyard, or private areas may give rise to harassment claims or privacy tort actions
• Audio-enabled cameras that capture a neighbor's private conversations may violate RSA 570-A:2
• New Hampshire courts may consider whether camera placement constitutes harassment or intentional infliction of emotional distress

Business Security Cameras

Retail and Commercial Surveillance

Businesses in New Hampshire commonly use security cameras for theft prevention, employee safety, and liability protection. Lawful business camera use includes:

• Silent video cameras in retail areas, lobbies, hallways, warehouses, and parking lots
• Point-of-sale cameras monitoring cash registers and checkout areas
• Loading dock and inventory area cameras for loss prevention
• Parking lot cameras for vehicle and pedestrian safety

What businesses must avoid:

• Cameras in employee bathrooms, locker rooms, or changing areas (RSA 644:9)
• Audio-enabled cameras that capture employee conversations without all-party consent (RSA 570-A:2)
• Hidden cameras in areas where employees or customers have a reasonable expectation of privacy
• Cameras positioned to record private areas of neighboring properties

Employee Notification

While New Hampshire does not have a specific statute requiring employers to notify employees about video surveillance, best practices include:

• Written notification in employee handbooks or policy documents
• Visible signage in areas monitored by cameras
• Consent forms if cameras record audio
• Clear communication about the scope and purpose of surveillance
• Consistent application of surveillance policies across all employees

Audio in Business Settings

RSA 570-A:2 specifically prohibits using electronic, mechanical, or other devices to intercept oral communications in business or commercial settings. If a business wants to record audio through security cameras, it must:

• Inform all employees, customers, and visitors about audio recording
• Obtain consent from everyone whose conversations will be captured
• Post conspicuous notices about audio recording
• Provide individuals with the option to avoid recorded areas

In practice, most New Hampshire businesses disable audio on their security cameras to avoid these complications.

Government and Public Building Cameras

Surveillance in Government Buildings

Government agencies in New Hampshire may install security cameras in public buildings, subject to the same legal framework:

• Silent video in public areas of government buildings is generally permissible
• Audio recording in government buildings triggers RSA 570-A:2 consent requirements
• Cameras in private areas (restrooms, changing rooms) are prohibited under RSA 644:9
• The Right-to-Know Law (RSA 91-A) may make government security camera footage subject to public records requests

Public Space Surveillance

Municipal cameras in public spaces (parks, downtown areas, traffic intersections) present unique considerations:

• Silent video surveillance of public spaces does not typically raise wiretapping concerns
• Individuals in truly public spaces generally have a diminished expectation of privacy
• Audio capture in public spaces remains subject to RSA 570-A:2 if speakers have a reasonable expectation of privacy
• Traffic enforcement cameras are governed by specific traffic statutes

Smart Home Security Devices

Doorbell Cameras

Internet-connected doorbell cameras (Ring, Nest Hello, Arlo, etc.) have become extremely common in New Hampshire. These devices raise specific legal considerations:

• Most doorbell cameras record both video and audio by default
• Audio recordings capture conversations between visitors, delivery workers, and passersby
• The all-party consent requirement under RSA 570-A:2 may apply to captured conversations
• Posting a visible sign stating that audio and video recording is in progress can reduce legal risk
• Consider disabling audio recording if legal compliance is a concern
• Sharing doorbell camera footage that includes private conversations could create additional liability

Smart Home Hubs and Voice Assistants

Devices like Amazon Echo, Google Home, and Apple HomePod are not traditional security cameras but do record audio. While these devices are primarily activated by voice commands:

• Recordings captured by these devices may be subject to RSA 570-A:2 if they capture private conversations
• Informing household members and guests about the presence and recording capabilities of these devices is a best practice
• Clips of accidental recordings shared publicly could create civil liability

Wireless Camera Systems

Wireless security cameras that connect to home Wi-Fi networks must comply with the same rules as wired systems. Additional considerations include:

• Cloud storage of footage should use encrypted connections
• Cybersecurity measures should protect against unauthorized access to camera feeds
• Neighbor notification is a best practice when wireless cameras may capture activity on adjacent properties
• Data retention policies should limit how long footage is stored

Penalties for Illegal Security Camera Use

Criminal Penalties

2024-2025 Court Rulings

In State v. Clark, 2024 N.H. 64 (N.H. Nov. 13, 2024), the New Hampshire Supreme Court held that the suppression remedy under RSA 570-A:6 applies only to felony violations of RSA 570-A:2, I, not to misdemeanor participant recordings under RSA 570-A:2, I-a. In State v. Hersom, No. 2023-0352 (N.H. Jan. 24, 2025), the court held that the State must prove NH jurisdiction and willful mental state before the suppression framework applies. Audio-enabled camera use that violates only RSA 570-A:2, I-a is not subject to automatic suppression as evidence.

Civil Liability

Victims of illegal security camera surveillance may pursue:

• RSA 570-A:11 damages: $100 per day or $1,000 minimum, plus punitive damages and attorney fees (for audio recording violations)
• Privacy tort claims: Intrusion upon seclusion, public disclosure of private facts
• Trespass claims: If cameras are physically placed on another's property
• Harassment claims: If cameras are used to intimidate or stalk
