How Long Is CCTV Footage Kept in Singapore?
CCTV footage is typically kept for 14 to 30 days at residential and standard business sites, with high-security environments such as banks and casinos holding recordings for 90 days to a full year. The exact duration depends on three variables: local privacy law, the system’s storage configuration, and any industry-specific mandate that applies to the sector.
How Long Does CCTV Footage Stay Saved? (By Property Type)
Retention practices vary considerably across property types, driven by risk profile, regulatory context, and the volume of footage generated each day.
- Home Systems: Typical retention runs from 7 to 30 days, depending on the storage method and capacity of the installed home security system.
- Commercial and Retail: Most setups retain 14 to 30 days of footage as a minimum, with longer durations recommended for high-footfall environments or premises handling disputes and insurance claims.
- Industrial and Construction: Standard practice sits at 30 days, extending up to 180 days where safety incidents or regulatory requirements apply.
- Banking and High-Risk Finance: Retention periods of 90 days to 6 months are common, reflecting the heightened evidentiary requirements and regulatory scrutiny in these sectors.
Factors That Affect How Long CCTV Footage Is Stored
Three variables set the ceiling on any CCTV footage retention period, and each can be adjusted independently at the specification stage.
- Storage Capacity: HDD or NVR capacity and the limits of any cloud storage plan directly dictate how far back recordings can be retrieved before older files are overwritten.
- Video Resolution: Higher resolutions such as 1080p or 4K consume significantly more storage per hour of recording, shortening total retention unless additional capacity is added to the system.
- Legal and Privacy Obligations: Singapore’s Personal Data Protection Act restricts organisations from retaining footage of identifiable individuals longer than is necessary for the original security purpose, which means retention windows should be intentional and documented.
Top Ways to Store CCTV Footage
CCTV recording storage falls into four broad categories, each suited to different site conditions and budget profiles.
Servers and Recorders (DVR and NVR)
A DVR processes footage at the recorder itself and is best matched to analogue camera setups, while an NVR encrypts and processes data at the camera, making it the preferred option for IP-based CCTV surveillance system deployments. Both formats support on-site storage and can be scaled with larger drives as retention requirements grow.
Surveillance Hard Drives
Surveillance-grade HDDs are purpose-built for continuous 24/7 write operations, which standard desktop drives are not engineered to sustain. These drives are optimised for the heavy write-to-read ratio typical of CCTV systems, spending roughly 90 per cent of operational time writing new footage and 10 per cent on playback.
Cloud Storage
Modern IP cameras can transmit footage directly to cloud platforms, enabling off-site backup and remote access without reliance on physical hardware at the premises. Reliable CCTV cloud storage depends on stable internet connectivity, though 4G or 5G links can support cloud backup at sites without a fixed-line connection.
SD Card Storage
Many current CCTV cameras support onboard MicroSD card recording, providing a localised backup that functions independently of the central recorder. Card capacity is limited, so this method is best used as a secondary or failover option rather than the primary retention solution.
How Sin Chew Alarm Helps You Get Your Storage Right
Choosing the right CCTV footage retention period and storage configuration involves balancing security requirements, budget, site conditions, and the organisation’s legal obligations under the PDPA. Getting it wrong can mean running out of storage before an incident is reviewed, or holding personal data longer than the law permits.
Sin Chew Alarm assesses each site individually before recommending a storage setup, whether that is an NVR-based local system, a cloud-backed solution, or a hybrid of both. Our CCTV system installations are sized to match resolution, camera count, and required retention duration, and can integrate with your existing access control when a unified security ecosystem is required.
