Direct-Drive EO/IR PTZ System
Zero-Backlash Architecture for Anti-Drone & Maritime Missions
The Challenge: Gears Limit Performance
In counter-UAS and maritime operations, traditional geared gimbals suffer from backlash, latency, and wear—causing target loss during rapid maneuvers or image blur on moving platforms. These mechanical limitations directly impact mission success.
Our Approach: Direct-Drive Architecture
We eliminate gears entirely. Torque motors connect directly to the payload axis—delivering pure mechanical response without transmission losses.
Key Advantages
Zero backlash: No lost motion during direction changes—critical for maintaining lock on agile drones
High bandwidth response:<10 ms reaction time to counter high-frequency vibrations (vehicle/ship motion)
Maintenance-free operation: No gears to wear, no lubrication required—designed for 24/7 deployment in harsh environments (desert dust, salt spray, -40°C to +70°C)
Mission-Proven Performance
Application | Technical Requirement | ZanVision Solution |
| Counter-UAS | Track 0.3m drone at 2 km with erratic maneuvers | ≤0.02° positioning accuracy + 120°/s pan speed ensures continuous lock without "overshoot-recover" lag |
| Maritime Patrol | Stable imaging in Sea State 4 (1.25–2.5m waves) | Optional dual-axis gyro stabilization maintains<0.1° line-of-sight jitter—optical view remains tripod-steady despite vessel motion |
Deployed with coast guard units in Southeast Asia and border security forces in the Middle East & Africa.

Why Direct-Drive Matters for Your Mission
Counter-UAS: Zero backlash prevents tracking loss during target zig-zag maneuvers—providing uninterrupted video for identification and neutralization
Maritime: Gyro-stabilized direct-drive maintains stable sightline while vessel rolls—extending effective observation time in rough seas
Border Surveillance: Maintenance-free operation reduces downtime in remote deployments—no gear replacement or re-lubrication required
