Q: What makes the ZN-SPM20U suitable for heavier payloads compared to 10kg models?
A: The medium-duty pan-tilt head delivers superior load-payload capacity through:
· 15kg (33lb) high-strength aluminum alloy construction
· High-precision stepper motor with worm gear drive ensures:
✓ ±0.1° preset accuracy (meets ANPR/LPR system requirements)
✓ Automatic self-locking when powered off (safety protection)
· IP66-rated full-sealed protection
Q: What's the tilt range for low-angle surveillance?
A: The extended -75° to +40° tilt range is optimized for:
· Traffic intersection monitoring (capturing license plates at steep angles)
· Airport perimeter security (tracking ground vehicles near fences)
· Industrial facility oversight (monitoring loading dock activities)
Q: What customizations does ZN-SPM20U Medium Duty Pan Tilt Head support?
A: We offer customization for:
• Pan/Tilt rotation speeds
• Horizontal rotation range and vertical tilt angle range.
• Load capacity
• Wiring harnesses and aviation connectors
• Control and rotation functions
• Partial shape, color, and connectors
Q: What payload mounting configurations does the ZN-SPM20U support?
A: 1. Top-Loading Configuration
2. Side-Loading Configuration
Technical Notice
The actual load capacity must be calculated based on the specific center of gravity height of your payload. Our engineering team can provide free load assessment for custom customer.
Q: What control protocols are supported?
A: The ZN-SPM20U supports:
· Primary protocols: Pelco D (default) & Pelco P
· Optional interfaces: RS-485/RS-422
