7 Tips to Optimise CCTV Camera Storage Costs

CCTV surveillance is an important aspect of today’s safety and security measures. When setting up CCTV systems to enhance monitoring and optimise safety, one of the key concerns that arises is storage. CCTV footage is often stored in bulk by individuals and organisations so that they can access it when needed. This CCTV storage is crucial not only for safeguarding people and assets but also for keeping track of activities in and around a business or organisation.

However, everyday CCTV cloud storage can quickly fill up a lot of digital space and become quite expensive. Fortunately, a few practical changes in how cameras record and where footage is kept can cut these costs significantly. In this article, you’ll learn about some practical tips you can follow to better manage and reduce your CCTV storage expenses.

Quick answer: The fastest ways to cut CCTV storage costs are switching to H.265 or smart codecs, recording on motion or schedule instead of 24/7 where possible, setting the right resolution and frame rate for each camera, keeping footage only as long as policy requires, and moving older footage to cheaper storage tiers. Together, these can reduce storage needs by 50% or more.

What Factors Affect CCTV Storage Capacity?

Several factors can significantly affect CCTV storage capacity. Some of these factors are elucidated below:

Resolution

Higher resolution videos consume much more CCTV storage space. Even short videos recorded in HD take up more space compared to longer videos recorded at lower resolutions. When CCTV footage is captured at a high pixel rate, it not only impacts CCTV storage capacity but also increases costs as larger recorded files require more CCTV storage resources.

Frame Rate

Frame rate is one of the major factors that highly affects CCTV storage capacity. It refers to the rate at which images appear every second in a footage. Frame rate determines the smoothness at which a video plays, which means the higher the frame rate is, the smoother the video will be. A lower frame rate makes motion look less smooth, but it creates smaller files, which helps in reducing CCTV storage costs.

Compression Technology

There are several modern technologies available for compressing video footage. These help reduce a video file’s size without compromising much on quality or storage needs. Technologies like H.264 and H.265 are highly effective in optimising CCTV storage. Solutions like CAMSTORE also offer smart compression features, making it easier to store large volumes of CCTV footage efficiently and cost-effectively.

Number of Cameras

The more the number of cameras, the more video recordings are generated. More data means larger file sizes, which affects both CCTV cloud storage capacity and overall cost. Planning camera placement so that coverage does not overlap unnecessarily keeps storage needs in check.

How Long Can CCTV Camera Footage Be Stored?

How long CCTV footage can be stored depends on the storage capacity of your NVR, DVR or cloud plan, the number of cameras, resolution, frame rate, codec and whether cameras record 24/7 or only on motion. Most businesses keep footage for 30 to 90 days, while banks, government sites and other regulated sectors may need longer retention under their own security guidelines. Once storage is full, the recorder overwrites the oldest footage automatically. To estimate how many days your system can hold, divide the total storage by the daily storage each camera uses - our guide to CCTV video compression and storage calculation explains the formula.

However, if there’s a need to store data for a longer period, one can opt for smart CCTV storage solutions like CAMSTORE and others. These solutions not only help save more data without compromising the clarity of video footage but also prove to be economical and effective in the long run.

How To Expand Existing CCTV Storage Capacity?

There are various ways to expand the existing CCTV storage capacity based on individual requirements. Generally, people invest a substantial amount in installing CCTV cameras, and depending on their storage capacity, these systems store data. Once the CCTV cloud storage capacity is reached, the system automatically starts deleting older files. Expanding CCTV storage is essential for preventing data loss, improving system performance, ensuring compliance with regulations, and more. There are ways to prevent this by following certain tips to retain video data for as long as possible:

• Add higher-capacity hard drives to your NVR or DVR

• Lower resolution or frame rate on non-critical cameras

• Add storage devices or use smart storage solutions like CAMSTORE

• Expand cloud storage by purchasing more space

7 Tips to Optimise CCTV Camera Storage Costs

The smaller the footage, the cheaper it is to store. Here are seven practical tips that work for most offices, retail stores, warehouses and government sites:

Tip 1: Switch to H.265 or Smart Codecs

H.265 (HEVC) needs roughly half the bitrate of H.264 for similar quality, and smart codecs like H.265+ cut it further in mostly static scenes. Most modern IP cameras and NVRs support it - often it is just a setting change.

Tip 2: Use Motion-Based or Scheduled Recording

Many areas see no activity for hours, such as storerooms at night or office floors on weekends. Recording on motion detection or on a schedule, instead of 24/7, can reduce storage by 30-70% in these zones, while keeping continuous recording for critical cameras like entrances and cash counters.

Tip 3: Set the Right Resolution, Frame Rate and Camera Count

Not every camera needs 4K at 30 fps. Use high resolution where you need to identify faces or number plates, and 1080p at 10-15 fps for general monitoring. Plan camera placement so that coverage does not overlap unnecessarily.

Tip 4: Turn Off Audio Where It Is Not Needed

In many cases, the primary focus is on capturing visual data, and audio recording may not add significant value. Turning off audio reduces the file size of each recording and also avoids privacy issues in some locations.

Tip 5: Right-Size Your Retention Policy

Keeping every camera's footage for the same duration is expensive. Define retention by zone - for example 90 days for entrances and cash areas, and 30 days for corridors - based on your business and compliance needs.

Tip 6: Use Tiered Storage

Keep recent footage on fast local storage such as an NVR (Network Video Recorder) with RAID for fault tolerance, and move older footage to cheaper high-capacity drives or cloud archive storage. This tiering approach is especially useful for large sites that must retain hundreds of terabytes for compliance.

Tip 7: Use a Smart CCTV Storage Solution

Smart storage tools like CAMSTORE compress footage further while keeping it usable, work with existing cameras and recorders, and make archived footage easy to search. Pair this with camera health monitoring from CheckCam, so storage is not wasted on blank or tampered feeds.

Final Thoughts

Video surveillance is an essential tool in the modern era, not only ensuring your safety but also providing security and helping you store valuable data. This data is crucial for identifying various aspects, such as gaining insights into your business, checking for thefts, and preventing potential crimes. Therefore, storing this data is essential.
