## Long description

DAHUA SD8A840-HNF-PA is an IP security camera designed for high-detail surveillance with a 3840×2160 resolution and a 1/1.8" CMOS sensor. The unit supports both indoor and outdoor ceiling mounting and provides long-range observation with 40x optical zoom and 16x digital zoom. Built for wired Ethernet connectivity and PTZ control, this camera offers 30 fps real-time capture, night vision and wide dynamic range for reliable performance in varied lighting conditions.
Advantages

Use PTZ presets and patrols to automate area sweeps and integrate alarm inputs/outputs for event-triggered recording or notifications.
Usage recommendations
For optimal long-range performance, perform periodic focus and optical alignment checks, ensure the mounting point provides clear sightlines, and configure appropriate bitrate and storage settings on your recorder to retain high-resolution footage. In outdoor installations, verify cable glands and seals remain intact to preserve IP67 protection.
