Can You Use an External Hard Drive for a Security Camera System?
Yes, you can use an external hard drive for a security camera system, particularly with NVR (Network Video Recorder) or DVR (Digital Video Recorder) systems. However, compatibility and performance depend on the specific hardware and its configuration. This article discusses suitable hard drives, installation tips, and the advantages of using dedicated surveillance drives.
What Types of Hard Drives Are Suitable for Security Cameras?
When selecting a hard drive for your security camera system, consider these types:
- Surveillance-Rated Hard Drives: Designed specifically for continuous writing and reading, these drives can handle the demands of 24/7 video recording.
- External USB Drives: While some systems support external USB drives, they may not be optimized for constant use.
- Internal SATA Drives: Commonly used in NVRs and DVRs, these drives typically offer better performance and reliability.
