How Long Should a Business Keep Security Camera Footage? 

No single retention period applies to every business. Many businesses use a retention period of approximately 30 to 90 days as a starting point, but this is a general planning guideline, not a universal legal requirement. Some businesses may need less storage, while others may need to retain certain recordings for longer because of industry regulations, contractual obligations, or documented security risks. 

 

When establishing a retention policy, consider: 

  • Business type: Different industries face different security and recordkeeping requirements. 
  • Security risks: Businesses with valuable inventory or frequent incidents may need longer retention. 
  • Storage capacity: Higher-resolution video and additional cameras require more storage. 
  • Legal obligations: Applicable laws, regulations, and contracts may affect retention requirements. 
  • Incident response: Footage related to an investigation may need to be preserved beyond the normal retention period. 
  • Privacy considerations: Keeping identifiable video longer than necessary may create additional privacy and data management risks. 

 

The goal is to retain footage long enough to meet legitimate security and operational needs without storing recordings indefinitely without a clear reason. 

 

What Factors Determine Video Retention Requirements? 

1. Industry and Regulatory Requirements 

Some businesses operate under specific rules governing surveillance, recordkeeping, or the handling of sensitive information. Depending on the industry and circumstances, these requirements may affect how long certain recordings should be retained and how they must be protected. Businesses should not assume that a standard 30-day or 90-day policy automatically satisfies their obligations. Requirements can vary by jurisdiction, industry, contract, and the type of information captured. 

 

For example, businesses handling sensitive customer information or operating in regulated environments should evaluate their applicable privacy, security, and recordkeeping obligations before establishing a policy. When requirements are unclear, consult qualified legal or compliance professionals to determine the appropriate retention period. 

 

2. Business Size and Security Risks 

The size and nature of your business also influence retention needs. A small office with limited public access may have different surveillance requirements from a distribution warehouse that handles valuable inventory and receives deliveries throughout the day. Consider whether your facility experiences frequent visitor traffic, after-hours activity, deliveries, employee access concerns, or recurring security incidents. 

 

Businesses with greater exposure to theft, vandalism, or operational disputes may benefit from longer retention windows, provided those periods are justified and consistent with applicable requirements. 

 

3. Camera Resolution and Recording Settings 

Video quality directly affects storage requirements. High-resolution cameras generally produce larger files than lower-resolution cameras, particularly when recording continuously. Retention also depends on whether cameras record continuously, only when motion is detected, or according to a customized schedule. 

 

For example, a business using multiple high-resolution cameras with continuous recording may need substantially more storage than a business recording selected areas based on activity. The best approach balances useful image quality, the number of cameras, recording schedules, and the desired retention period. 

 

4. Storage Capacity and Budget 

Businesses must also determine whether their storage infrastructure can accommodate the required footage. Common options include local network video recorders (NVRs), digital video recorders (DVRs), dedicated storage systems, and cloud-based surveillance platforms. Each option has different costs, capacity limits, and management requirements. 

 

Design a system around the business's retention policy rather than whatever storage happens to be available. Otherwise, older footage may be overwritten before you need it. 

 

What Are the Best Ways to Store Security Camera Footage? 

Choosing an appropriate storage method helps businesses retain recordings reliably and retrieve them when necessary. 

 

1. Local Video Storage 

Local storage uses equipment installed at the business premises, such as an NVR, DVR, or dedicated storage server. This approach can provide direct control over recordings and allow authorized personnel to review footage without depending entirely on a cloud service. However, storage capacity is limited by the equipment and drives installed. Businesses using local storage should consider equipment security, backup power, drive health, physical access restrictions, and protection against theft or damage. 

 

2. Cloud-Based Video Storage 

Cloud storage sends recordings to a remote service through an internet connection. Depending on the provider and subscription, businesses may be able to access footage remotely, expand storage, and manage retention settings through an online platform. However, cloud storage depends on the service's capabilities, connectivity requirements, and subscription terms. Businesses should review retention limits, storage costs, data protection practices, and the process for exporting recordings. 

 

3. Hybrid Storage Solutions 

A hybrid system combines local recording with cloud storage or another backup method. This approach may provide additional flexibility by maintaining local recordings while storing selected footage remotely. For businesses with important surveillance requirements, hybrid storage can help address certain risks associated with relying on one storage location. The right configuration depends on the facility's security priorities, available bandwidth, and budget. 

 

Why Businesses Should Establish a Formal Video Retention Policy 

A written retention policy helps ensure that security footage is managed consistently. Without clear procedures, businesses may retain recordings unnecessarily, delete footage too early, or struggle to locate important evidence after an incident. 

 

An effective policy should identify: 

  • The standard retention period for each camera system. 
  • Which employees can access recorded footage. 
  • How recordings are exported and shared. 
  • When footage should be preserved for an investigation. 
  • How recordings are securely deleted or overwritten. 
  • Who is responsible for reviewing and maintaining the policy. 

 

Businesses should also establish a process for preserving relevant footage when an incident occurs. If an accident, theft, workplace complaint, or legal dispute is reported, the relevant recordings may need to be protected from automatic deletion. Review retention policies periodically to reflect changes in business operations, storage capacity, and applicable requirements.
