FAQ's About Storage
What is the best storage option for CCTV cameras, HDD or SD card?
For most CCTV setups, hard drives (HDD) are the best option for long-term storage due to their larger capacity and ability to handle continuous recording from multiple cameras. HDDs can store terabytes of video footage, making them suitable for commercial or residential CCTV systems with multiple cameras. On the other hand, SD cards are typically used in cameras with local storage, but they are limited in capacity and generally not ideal for long-term storage of large amounts of footage.
How big should my CCTV hard drive be?
The size of your CCTV hard drive depends on several factors, including the number of cameras, the resolution of your recordings, and how long you want to store footage. As a general guideline, for a basic 4-camera system with 1080p resolution, a 1TB to 2TB hard drive can store approximately 30-60 days of footage, assuming continuous recording. For larger systems or higher resolution cameras, you may need 4TB or more. Always consider your needs for storage duration and video quality.
What are the differences between HDD and SSD for CCTV storage?
While HDDs (Hard Disk Drives) are more common for CCTV storage due to their larger capacity and lower cost, SSDs (Solid State Drives) can be used as well. SSDs are faster and more durable but come at a higher price per gigabyte. For typical CCTV setups, an HDD is sufficient, but an SSD may be considered for high-performance needs where speed and durability are critical.
Can I use an SD card for CCTV storage?
Yes, you can use an SD card for storing footage in certain CCTV cameras, especially those designed with local storage options or IP cameras with SD card slots. However, SD cards are generally limited in storage capacity, with typical cards ranging from 16GB to 512GB. For short-term storage or low-resolution cameras, SD cards may be a convenient option, but for larger CCTV systems requiring longer storage durations, hard drives or network video recorders (NVRs) are recommended.
What is the recommended SD card size for CCTV cameras?
The recommended size of an SD card for CCTV cameras depends on factors like the camera's resolution, recording frequency, and whether it's used for continuous or motion-triggered recording. For 1080p cameras, 64GB to 128GB SD cards are typically suitable for storing a few days' worth of footage. For 4K cameras, 256GB or larger cards may be necessary. It's always best to check the camera's specifications to ensure compatibility and optimize storage performance.
