Recommendations

For reliable operation, use a high-quality surveillance-grade HDD sized according to desired retention time, place the recorder in a ventilated, dust-free environment, and secure network access with strong passwords and up-to-date firmware. For installations with multiple cameras or higher resolution needs, verify network bandwidth and storage capacity before deployment.
