WD Purple hard drives are designed specifically to handle heavy workloads from CCTV security cameras.

Your CCTV security system is only as good as the hard disk backing it. A CCTV camera is just the beginning of a surveillance system, the seeing eye. WD Purple hard drives are the heart and brain of surveillance, powering the entire dynamic to help keep you safe, without skipping a beat.

The whole purpose of installing CCTV cameras is to be able to clearly record what is happening and to go back and check the footage whenever needed. General desktop hard-drives are typically not tested for high write work-loads compared to surveillance HDDs. The storage device for a security camera system should be able to record, store and re-play videos non-stop from multiple feeds. In case of any technical glitch that can cause hang-ups, the hard drive should have features to help move on to capture the next frame, or risk losing crucial footage.

Built to last for 24/7 Surveillance Systems

Surveillance systems can be extremely demanding, requiring uninterrupted capture and streaming, endurance for wide weather fluctuations and adaptability for unforeseen errors. Western Digital, a global leader in digital storage solutions, offers an unmatched portfolio of storage devices for surveillance cameras; for DVRs, standard and AI enabled NVRs, server-based VMSs, and cloud server based CCTV systems.
