Storage Technologies For Video Surveillance And Impact On VMS Performance
The surveillance industry continues to transition from analogue to digital. This transition is taking place on two fronts - how the images are captured and how they are stored. The way surveillance images are stored has also changed from analogue-based recording solutions - like VHS tapes and film- to digital storage on hard drives. As a result, most surveillance systems in place today make use of hard disks to store surveillance images digitally. With hard drive capacity doubling approximately every two years and the cost per unit shrinking by 50% surveillance storage is less expensive, more efficient and progressively powerful.
This white paper explores available surveillance video storage technologies and the impact of each solution on video management software performance. The white paper aims to arm security and IT professionals with key information to make the best storage decisions when designing a surveillance system.
