High-Performance Pan-Tilt Unit

Dual-Axis Platform Mounted System for Ground Applications

HELLENIC INSTRUMENTS offers the HI-PTU100-NST high-performance pan-tilt unit for precise observation and real-time positioning of various payloads, including thermal cameras, video cameras, laser rangefinders, and microwave antennas. The HI-PTU100-NST offers high precision, user-controlled position and speed movements for payloads up to 25 pounds, utilizing precise stepper motors with embedded encoders. Built-in features include internal wiring with slip ring allowing for continuous pan rotation, fully configurable ranges of motion and parameters through Ethernet web interface.  A fully integrated design suitable for intense applications in all weather conditions provides effortless integration to existing systems, minimizing your integration and development costs.


A heavy-duty mid-range pan-tilt unit for payload positioning of up to 25 pounds, best for multi-part payloads in fixed and mobile applications. The body of the HI-PTU100-NST is constructed from machined aluminium, providing rigid and repeatable positioning of payloads. Utilizing precise stepper motors with embedded encoders, the HI-PTU100-NST is capable of delivering high-performance payload positioning for improved monitoring through thermal imagers, as well as maintaining direct communication links when in transit. Application scenarios include platforms in ground, from boarder control towers to coastal security.
