One of the most common questions homeowners and business owners in Australia ask is: how long do CCTV recordings last? The answer depends on several factors, including the type of system you use, your storage capacity, and your recording settings. At Niko Computers, we provide expert advice on CCTV systems to ensure you always have the right amount of footage when you need it most.
On average, CCTV recordings last between 7 to 30 days. Most modern systems automatically overwrite old footage once storage is full. For small businesses or homes, 1–2 weeks of storage may be enough. For larger businesses or high-security environments, 30–90 days of recordings may be required.
Several factors determine how long your CCTV footage is stored:
Storage Capacity – The size of your DVR, NVR, or cloud storage directly affects retention time.
Number of Cameras – More cameras recording simultaneously use more storage space.
Video Quality – Higher resolution (HD/4K) produces larger files, reducing recording time.
Recording Settings – Continuous recording uses more storage than motion-activated recording.
Cloud vs Local Storage – Cloud systems may allow extended storage plans, while DVR/NVR units depend on hard drive capacity.
If you need to keep CCTV footage longer, there are several solutions:
Upgrade to larger hard drives in your DVR or NVR.
Adjust recording settings to motion detection instead of continuous recording.
Use cloud-based storage for extended retention.
Regularly back up important footage to external drives.
