Reliable storage is an important part of any video surveillance system because recordings are only useful when they can be retrieved when needed. The Hikvision Turbo DVR 8-channel solution can use a compatible hard drive to store video from connected cameras, subject to the model's supported capacity and storage interface. The amount of footage retained depends on drive size, camera resolution, frame rate, compression, recording schedules, and the number of active channels. Businesses that need longer retention periods should calculate their expected storage requirements before installation. A compatible surveillance-rated hard drive may be appropriate for continuous recording workloads. Check the DVR's supported drive capacity and installation requirements to build a suitable recording system.
