Hard Drives Made for Video Surveillance

Recording multiple channels of HD video requires a hard drive that can keep up with the workload. Our Purple Series hard drives are designed specifically for surveillance video recorders. They can keep up with the work load, assuring reliable and smooth video recording at all times.

The video recorder stores the video footage on internal hard drives. The size of the drive and the recording options determine the total number of days the system can store. The hard drive calculator below allows you to set the values for your application and calculate the storage needed.

Can I use any hard drive for surveillance?

The answer is simple, yes! Any SATA hard drive will work in most surveillance video recorders. The question that should be asked is; How long will a normal hard drive last recording multiple 4K video streams? The answer is, a year or less. The fact is normal PC SATA hard drives are not built for the heavy workloads of a video surveillance system and they will prematurely fail.
