Surveillance grade storage solutions at RhinoCo Technology
Reliable hard disk drives & SD cards for your installs
Choosing surveillance grade storage solutions is crucial for any CCTV system as they are built for continuous 24/7 recording. At RhinoCo, we supply surveillance hard disk drives (HDDs) and microSD cards as they are designed to handle heavy surveillance workloads. Generally, they are more reliable, have higher write speeds and can be rewritten multiple times over without fail, more so than your traditional HDDs and SD cards that can be used in computers, phones and DSLR cameras.
Surveillance storage systems designed for 24/7 surveillance
Surveillance grade storage solutions such as those from Seagate and Western Digital are designed to always be active and operating 24/7 to store video evidence. These hard drives and SD cards are constantly being written on, unlike regular computer drives which operate intermittently. Thus, when choosing a storage solution for a CCTV install, it is important that you choose surveillance grade over standard retail options for better quality and increased reliability.

Other things to consider when choosing a storage solution
There are a few key things to keep in mind when selecting either a hard drive or microSD card.
- Quality: What is the resolution of the cameras and how many frames per second are they recording?
- Archiving: How long does the footage need to be stored before it’s rewritten?
- The Scene: Not all scenes require a high resolution or high FPS to deliver sufficient results
- Compression: The type of compression can either increase or decrease archiving capabilities.
