Security cameras can help a business investigate theft, accidents, property damage, employee incidents, customer disputes, and other events. But installing cameras is only part of the equation. Businesses also need to decide how long their recordings should be kept.
So, how long should a business keep security camera footage?
For many businesses, 30 to 90 days is a practical starting point, but there is no single retention period that works for every organization. The right amount of time depends on the type of business, the purpose of the cameras, available storage, insurance requirements, company policies, and any legal or regulatory obligations that apply to the organization.
Keeping footage for too little time can mean losing important evidence before anyone realizes they need it. Keeping everything indefinitely, on the other hand, can require significantly more storage and make managing recordings unnecessarily complicated.
The goal is to establish a retention period that matches the actual needs and risks of the business.
How long should a business keep security camera recordings?
A common retention period for business security cameras is 30 days, while some businesses choose 60 or 90 days depending on their circumstances.
There are situations where a longer retention period may make sense. A business that handles valuable merchandise, operates in a high-risk environment, or needs to maintain footage for a particular contractual or regulatory reason may decide that several months of retention is more appropriate.
The important question is not simply, “How long can our cameras record?”
Instead, businesses should ask, “How long might we realistically need a recording before we know an incident occurred?”
Consider a situation where an employee notices missing inventory several weeks after it disappeared. If the camera system automatically deleted footage after seven days, the recording may already be gone by the time anyone begins investigating.
That is why retention should be based on the business's risks and how quickly incidents are normally discovered.
What determines how long security camera footage should be kept?
Several factors can influence a business's ideal retention period.
The type of business
A small professional office may have different surveillance needs than a jewelry store, warehouse, medical facility, restaurant, construction site, or retail business.
A business that handles expensive products or maintains valuable equipment may have a greater reason to retain footage for longer periods.
The locations being monitored also matter. Cameras covering a parking lot, entrance, cash register, warehouse, server room, or restricted area may have different purposes and therefore different retention requirements.
How quickly incidents are discovered
Think about how long it typically takes your business to discover a problem.
If a retail store notices a register discrepancy at the end of each day, a shorter retention period may be sufficient for some investigations. If inventory is checked weekly or monthly, the business may need recordings to remain available for considerably longer.
The longer it can take to discover an incident, the more important an adequate retention period becomes.
Insurance requirements
Some insurance policies or claims processes may involve documentation related to an incident. Businesses should review their policies and speak with their insurance provider if they are unsure whether specific surveillance records need to be retained.
It is better to understand these expectations before an incident occurs rather than discovering after a claim that relevant footage is no longer available.
Legal and regulatory requirements
Certain industries may have specific requirements concerning surveillance, privacy, security records, or the handling of sensitive information.
There is no universal retention period that applies to every business, so organizations should determine whether industry-specific rules, contracts, or local requirements affect their surveillance practices.
Businesses that operate in regulated industries should involve the appropriate legal or compliance professionals when establishing their retention policy.
Available storage
The amount of video a system can retain also depends on its storage capacity.
Higher-resolution cameras generate larger video files. A system recording continuously from several cameras will generally use more storage than a smaller system recording fewer cameras or using motion-based recording.
For example, a business with 20 cameras recording continuously at high resolution will have very different storage requirements from a small office with four cameras recording primarily when motion is detected.
This is why storage planning should happen when the camera system is designed, rather than after the business discovers that it is constantly running out of recording space.
Does a security camera automatically keep footage for 30 days?
No. The retention period depends on how the camera system is configured and where recordings are stored.
Some systems overwrite older recordings automatically when available storage reaches capacity. Others may store recordings in a cloud platform with a specific retention plan.
A system configured for 30 days of retention may automatically delete or overwrite older footage once the storage limit is reached. If an incident occurs, the business needs to identify and preserve the relevant footage before it is automatically overwritten.
This is one reason businesses should understand exactly how their surveillance system handles storage and deletion instead of assuming that recordings will remain available indefinitely.
What happens when security camera storage is full?
Many security camera systems use continuous recording and overwrite the oldest footage when storage becomes full.
This is generally an expected part of how surveillance systems operate. The problem occurs when a business does not realize that important footage will be automatically overwritten.
For example, imagine that an incident happened 45 days ago, but your system only retains 30 days of recordings. By the time someone realizes they need that footage, it may already have been replaced by newer recordings.
Businesses should therefore establish a process for identifying and preserving important footage as soon as an incident is reported.
If a recording may be needed for an investigation, insurance claim, legal matter, or internal review, it should be exported or otherwise preserved according to the business's policies rather than left on the camera system until it is automatically overwritten.
Should security cameras record continuously or only when there is motion?
There is no universal answer because both approaches have advantages.
Continuous recording provides a complete record of what happened during a particular period. This can be useful when an incident is not immediately obvious or when the exact timing of an event is uncertain.
Motion-based recording can reduce storage requirements because the system records only when movement is detected according to its configuration.
However, motion detection is not perfect. Camera positioning, lighting, environmental conditions, and system settings can affect what gets recorded.
Businesses should choose their recording approach based on what the cameras are intended to monitor. A camera protecting a rarely used storage area may have different requirements from a camera monitoring a busy entrance or cash register.
How much security camera storage does a business need?
Storage requirements depend on several factors, including the number of cameras, resolution, frame rate, compression, recording schedule, and desired retention period.
A business with more cameras and higher-resolution video will generally require more storage to maintain the same number of days of footage.
This means that deciding to keep recordings for 90 days instead of 30 days can have a significant effect on the storage requirements of a larger surveillance system.
When planning a new installation, businesses should determine the desired retention period first and then make sure the recording hardware or cloud service can support it.
If your business is considering new cameras or expanding an existing system, security camera installation should include more than simply deciding where to mount the cameras. Storage, recording settings, network requirements, remote access, and future expansion should all be considered.
Is cloud storage better for security camera footage?
Cloud-based camera storage can make recordings easier to access from different locations, but it is not automatically better for every business.
Cloud systems can provide remote access and reduce the need for businesses to maintain local recording hardware. Depending on the system, businesses may also be able to adjust retention periods or add storage as their needs change.
Local storage, meanwhile, gives a business physical control over its recording equipment and may make sense when a company wants to keep recordings on-site.
The right choice depends on factors such as the number of cameras, retention requirements, internet connectivity, security considerations, storage capacity, and how the business wants to access its recordings.
Some businesses may also benefit from a combination of local and cloud storage.
What should a business do when an incident is captured on camera?
If a security camera records an incident that may need to be investigated, the business should preserve the relevant footage as soon as possible.
Do not assume that leaving the recording on the camera system is enough. If the system automatically overwrites older footage, the recording could disappear before the investigation is complete.
The business should identify the approximate date and time of the incident, locate the relevant camera, export the appropriate footage, and store it according to its internal procedures.
Access to the recording should also be limited to people who have a legitimate reason to review it.
Businesses should establish these procedures before an incident occurs so employees know what to do when important footage needs to be preserved.
How should businesses protect security camera footage?
Security camera recordings are business data, and they should be treated accordingly.
If cameras are connected to the company network, businesses should consider how the camera system is protected from unauthorized access. This includes using strong account credentials, limiting administrative access, keeping camera and recording equipment updated when appropriate, and securing remote access.
Network configuration matters as well. Security cameras should not simply be installed and forgotten, particularly when they are connected to the same network used by computers, servers, phones, and other business systems.
Businesses can also review how their surveillance system fits into their broader cybersecurity strategy.
A camera system may help protect physical property, but the cameras themselves are connected devices that can introduce security concerns if they are poorly configured or left with outdated software and weak credentials.
What happens if security camera footage is needed after the retention period?
If footage has already been overwritten or deleted, recovering it may not be possible.
That is why businesses should determine their retention requirements before they need the recordings.
If an employee reports an incident, a customer raises a dispute, or management discovers missing inventory, the business should act quickly to identify and preserve relevant footage.
It can also be helpful to have a written process explaining who is responsible for reviewing recordings, when footage should be exported, where preserved footage should be stored, and who is authorized to access it.
This turns video surveillance from something that simply records events into a system that the business can actually use when an incident occurs.
How often should a business review its camera system?
A security camera system should not be installed and then ignored for years.
Businesses should periodically check whether cameras are still functioning correctly, whether important areas are still covered, whether image quality remains adequate, and whether storage capacity matches the desired retention period.
Changes to the building can also affect camera coverage. New walls, equipment, shelving, entrances, construction, or changes in how an area is used can create blind spots that did not exist when the cameras were originally installed.
It is also worth reviewing who has access to camera recordings and whether former employees or unnecessary accounts still have access.
A periodic review can identify these problems before the business actually needs a recording.
Frequently Asked Questions
How long do most businesses keep security camera footage?
Many businesses retain security camera footage for approximately 30 to 90 days. The appropriate period depends on the business's operations, risks, storage capacity, insurance requirements, and any applicable legal or regulatory obligations.
Is 30 days enough for security camera footage?
Thirty days may be sufficient for some businesses, but it is not ideal for every situation. If incidents can take several weeks to discover, the business may benefit from a longer retention period so relevant footage is still available when an investigation begins.
How long should a retail store keep security camera footage?
A retail store should determine its retention period based on factors such as inventory cycles, theft risks, incident reporting practices, insurance requirements, and storage capacity. A 30- to 90-day period is commonly considered, but the appropriate period should be determined for the individual business.
Do security cameras delete old footage automatically?
Many security camera systems are configured to overwrite older recordings when available storage is full. The exact behavior depends on the camera and recording system. Businesses should understand their system's retention and overwrite settings so important footage is not lost unexpectedly.
Can deleted security camera footage be recovered?
Once security camera footage has been overwritten or permanently deleted, recovery may not be possible. If a recording may be needed for an investigation, the business should preserve it as soon as possible rather than relying on the camera system to retain it indefinitely.
Should businesses keep security camera footage longer than 90 days?
Some businesses may have a legitimate reason to retain recordings longer than 90 days, particularly when incidents take longer to discover or specific business, contractual, insurance, or regulatory requirements apply. Longer retention also requires additional storage and appropriate policies for managing the recordings.
Conclusion
There is no magic number that determines how long every business should keep security camera footage. For many organizations, 30 to 90 days can provide a reasonable starting point, but the right retention period depends on how the business operates and how quickly incidents are likely to be discovered.
The more important question is whether your current system gives you enough time to identify an incident and preserve the footage before it is automatically overwritten.
Businesses should also consider storage capacity, camera placement, recording settings, remote access, user permissions, and the security of the camera system itself. A surveillance system is most useful when the business knows what it records, how long it keeps those recordings, and what to do when an important event is captured.
