University Surveillance: How Long Do Cameras Keep Recording?

The retention period for security camera footage varies depending on several factors, including the type of organisation, storage capacity, industry standards and legal requirements. For most businesses, the typical retention period ranges from 30 to 90 days, with some larger corporations storing footage for up to three months. However, certain industries, such as banks and casinos, may retain footage for a minimum of six months to a year due to regulatory and security reasons. Ultimately, the decision on how long to keep surveillance recordings is influenced by a combination of policy, security needs and available storage space.

How long do university surveillance cameras typically keep footage?

The length of time that university surveillance cameras retain footage varies and is dependent on several factors. These include the storage capacity, camera resolution, recording settings, and legal requirements.

On average, security cameras across various sectors, including hotels, retail stores, supermarkets, and construction companies, typically store footage for 30 to 90 days. This is largely due to the significant amount of bandwidth and storage that video recordings consume. However, the specific duration can be adjusted based on the user's needs and preferences, and some businesses may store footage for longer durations.

In certain industries, such as banking and casinos, regulatory standards and state regulations require a minimum retention period of 6 months. This is to ensure compliance with industry-specific requirements and to maintain necessary records for legal or investigative purposes.

It is worth noting that the type of storage system also plays a role in determining the retention period. Traditional analog or digital video recorder (DVR) systems and network video recorder (NVR) systems often have shorter retention periods, typically ranging from a few days to several weeks, while cloud-based systems offer customizable retention periods based on subscription plans.

Ultimately, the decision on how long to retain surveillance footage is influenced by a combination of legal requirements, storage capacity, and the specific needs of the university or organization operating the cameras.

What factors influence how long university surveillance footage is kept?

The retention period for university surveillance footage can vary due to several factors, including legal, regulatory, and operational considerations.

One crucial factor is the purpose of the footage. If the video recordings are needed for criminal investigations, legal proceedings, or regulatory compliance, they are typically retained for a more extended period. For example, in the case of Tufts University, footage is stored for up to 30 days unless it is required for criminal investigations or court proceedings, in which case it is kept for a longer duration.

The storage capacity and technology used also influence retention time. Universities with larger storage capacities and advanced storage technologies can retain footage for more extended periods. For instance, Internet Protocol (IP) cameras with cloud storage or Network Video Recorders (NVRs) offer more scalable and flexible storage options compared to traditional analogue CCTV systems.

The number of cameras in the surveillance system and the video resolution further impact retention time. A higher number of cameras and higher-resolution footage result in larger file sizes, requiring more storage space.

Additionally, the type of recording method employed can be a factor. Continuous 24/7 recording fills up storage faster, leading to an earlier deletion of footage, whereas scheduled or motion-based recording can allow for longer retention.

The specific policies and regulations of the university and its location also play a role in determining retention time. For example, privacy laws and data protection regulations may mandate the deletion of footage when it is no longer required, as is the case with Australia's Privacy Act 1988.

In summary, the retention of university surveillance footage is influenced by a combination of legal, technical, and operational factors, with the primary consideration being the purpose for which the footage is needed.

How do different recording methods affect how much footage is available?

The recording method used by a security camera system can significantly impact the amount of footage that can be stored and the duration for which it can be retained. The choice of recording method depends on various factors, including the purpose of the footage, the number of cameras, the available storage space, the resolution of the cameras, and the desired retention period.

One common method is to save footage directly to the camera using onboard storage options like MicroSD cards. The storage capacity of these cards varies, typically ranging from 128GB to 256GB. The amount of activity captured by the camera determines how long the footage can be stored. For instance, a busy street with constant motion may fill up the card within a day or two, while less active locations could go for weeks or even months without filling up the storage. MicroSD cards are ideal for standalone cameras and can also serve as a backup for a full video surveillance system.

Another approach is to use external recorders, such as network video recorders (NVRs) for IP systems or digital video recorders (DVRs) for analog systems. These recorders have built-in hard drives, with capacities ranging from 500GB to 10TB. The storage duration depends on the size of the hard drive and the resolution of the camera. Some recorders can accommodate multiple hard drives, allowing for even longer retention periods.

Cloud-based systems offer subscription plans with varying storage amounts. Basic plans may offer storage for a limited number of days, while premium plans can extend this duration to several weeks or months. The cloud provides the advantage of remote access to footage but may require a stable internet connection and a subscription fee.

The choice between continuous recording, motion-activated recording, and scheduled recording also impacts the amount of footage that can be stored. Continuous recording consumes more storage space, while motion-activated recording and scheduled recording can help conserve storage by only capturing events or recording during specific times.

In summary, the recording method, storage capacity, camera resolution, and recording settings all influence the amount of footage that can be stored and the duration for which it can be retained. Businesses typically aim for at least one month's worth of footage, while homeowners often settle for one to two weeks. Ultimately, the specific needs and preferences of the user dictate the choice of recording method and the resulting storage capacity.

What happens to old university surveillance footage?

The retention period for security camera footage varies depending on the organisation and the purpose of the footage. Most businesses store security footage for 30 to 90 days, but some may keep it for longer, especially if it is needed for legal proceedings. In the case of universities, there may be specific data retention policies or regulatory requirements that dictate how long surveillance footage must be kept.

In general, the length of time that security cameras keep footage depends on factors such as storage capacity, camera resolution, recording settings, and legal or regulatory requirements. Smaller systems, such as those used in homes or small businesses, may only store footage for about 1-2 weeks, while larger commercial setups can retain footage for several months. Cloud-based storage options offer customizable retention periods based on user preferences and subscription plans.

In many security systems, especially those with limited storage, old footage is automatically deleted or overwritten to make room for new recordings. This ensures that the storage does not become full and that the camera can continue to record without interruption. However, if certain footage is needed for legal or record-keeping purposes, users may choose to transfer it to external storage devices or cloud services for long-term preservation.

To extend the retention period of security camera footage, users can employ various tactics such as lowering the resolution or frame rate, using efficient compression algorithms, leveraging motion detection settings, or increasing the storage capacity by using external hard drives or cloud storage solutions.

What are the options for video storage?

There are two main options for storing security camera footage: local storage and cloud storage.

Local Storage

Local storage saves footage on a physical device, such as a hard drive or SD card, located at the premises being monitored. This type of storage offers several advantages, including:

• No monthly fees: Local storage does not require a subscription fee, making it a cost-effective option.
• Enhanced privacy: With footage stored on-site, there is less risk of data breaches or unauthorized access.
• Reliability: Local storage is less dependent on internet connectivity, ensuring footage is continuously recorded, even during network outages.
• Immediate access: Users can directly access stored footage without an internet connection, making it faster to review videos when needed.

However, local storage also has some drawbacks, such as:

• Limited storage capacity: The amount of footage that can be stored is restricted by the capacity of the physical storage device.
• Risk of damage or theft: Local storage devices are susceptible to physical damage, theft, or natural disasters, which could result in the loss of crucial security footage.
• Maintenance: Regular maintenance is required to ensure devices function correctly and efficiently manage storage space.
• Lack of remote accessibility: While internet connectivity is not needed to access footage, remote access can be more challenging without cloud capabilities.

Cloud Storage

Cloud storage, on the other hand, uploads and stores video footage on a service provider's remote servers, accessible via the internet. This option offers the following benefits:

• Enhanced security: Cloud storage keeps videos safe from theft or damage to the camera since footage is stored remotely.
• Backup to local storage: Cloud storage acts as a secondary backup to local storage, providing an additional layer of protection.
• AI integration: Cloud storage enables the use of artificial intelligence for features like person and vehicle detection.
• Remote accessibility: Cloud storage allows users to access footage from anywhere with an internet connection.

However, there are also some disadvantages to cloud storage, including:

• Monthly fees: Most cloud storage providers charge a recurring fee for their services, which can be costly over time.
• Internet dependency: Cloud storage is wholly dependent on the internet; if the camera is offline, there is no way to record videos.
• Standardization and compatibility issues: There is no standardized pricing across brands, and cloud storage is often not cross-compatible with other brands.

Hybrid Cloud Storage

A third option that combines the benefits of both local and cloud storage is hybrid cloud storage. This approach utilizes both local and cloud storage methods to maximize advantages and minimize drawbacks. For example, hybrid cloud storage can provide the reliability and immediate access of local storage while also offering the remote accessibility and backup capabilities of cloud storage.
