FAQ

FAQ:  Mini Bullet Camera ZN-SPB3381V50-ES


Q: What makes this PTZ bullet camera ideal for challenging lighting environments?

A:This mini PTZ bullet camera features Video Analysis Light-Adjustment Technology, adaptive WDR, and customizable image settings (sharpness, contrast, saturation, brightness) to ensure clear image capture in both bright and low-light scenes.


Q: Can the camera automatically remove dust or rain droplets from its view?

Yes — there is an optional built-in mechanical wiper (optional) that helps keep the lens clear in harsh outdoor conditions like rain or dust.


Q: What are the pan/tilt capabilities and preset functions?

A:The camera offers 360° pan (0.1°–80°/s) and -40° to 55° tilt (0.1°–20°/s), with support for 256 preset positions, 8-group auto scan (32 presets each), 8-group auto cruise, and 4 pattern paths for flexible surveillance routes.


Q: What’s the level of ingress protection and how does it perform in outdoor conditions?

A: With an IP66 rating, this camera is dust-tight and protected against powerful water jets, operating reliably between -35 °C and +60 °C (-31 °F to 140 °F). It also supports optional PoE for simplified outdoor wiring.


Q: What is the maximum optical zoom and IR night vision range?

A:It comes with a 33× optical zoom lens (4.7 mm to 155 mm) and delivers clear infrared night vision up to 100 m (328 ft), making it ideal for long-distance monitoring.
