Pan and Tilt Unit 10 kg
Compact Two-Axis Surveillance Positioner for EO Sensor & Camera Payloads
The Pan and Tilt Unit 10 kg is a custom-built, stand-alone two-axis surveillance positioner designed and supplied by System Controls for mounting and controlling electro-optical sensors, cameras and surveillance payloads in elevation over azimuth configuration.
What is the Pan & Tilt Unit 10 kg?
The Pan and Tilt Unit 10 kg is a compact, rugged two-axis positioner in elevation over azimuth configuration, designed to rigidly mount and precisely control surveillance sensor payloads in both pan and tilt axes. The pan axis is a continuously rotating system with zero backlash, a DC motor with encoder and precision gear trains for position and rate control. A high precision encoder on each motor shaft provides position feedback to the motion controller.

Continuous 360-Degree Pan with Integrated Slip Ring
The pan axis delivers N x 360° continuous rotation via an integrated slip ring, enabling uninterrupted surveillance coverage across the full azimuth without cable wind-up or rotation limits. Zero backlash precision gear trains and a DC motor with encoder provide accurate, repeatable pan positioning at speeds from 0.008°/sec to 120°/sec across the full range.
Flexible Multi-Payload Mounting Architecture
The PTU supports top mount and dual side mount payload configurations using dedicated adapters, enabling simultaneous mounting of multiple sensors including visible cameras, thermal imagers and other electro-optical payloads. One top and two side payload mounting brackets are supplied as standard, with custom configurations available as per requirement.
Wide Speed Range for Surveillance and Tracking
Both pan and tilt axes cover a speed range from 0.008°/sec to 120°/sec, providing the slow, precise scan rates needed for area surveillance and the fast slew rates required for target tracking and rapid sensor repositioning. Speed, position and acceleration are all precisely controlled through the integrated motion controller and digital encoder feedback.
Multiple Communication Interfaces and GUI Control
The PTU supports RS232, RS485, RS422 and Ethernet communication interfaces, enabling direct integration with a wide range of host processors and command systems. A Windows 7/8.1/10 GUI and a rugged joystick controller with PTU controller are supplied as standard, providing both software and manual control options for field operators.

The PTU provides N x 360° continuous pan rotation via an integrated slip ring and a tilt range from +30° to -90°. Both ranges are programmable with speeds from 0.008°/sec to 120°/sec and 0.002° resolution on both axes.
The PTU supports a maximum payload of 10 kg using top mount, dual side mounts, or a combination of both via dedicated adapters. One top and two side payload mounting brackets are supplied as standard and can be configured to meet specific customer requirements.
The PTU supports RS232, RS485, RS422 and Ethernet. A Windows 7/8.1/10 GUI and a rugged joystick with PTU controller are included as standard for both software-based and manual field operation.
The PTU has an IP65 ingress protection rating and is JSS 55555 compliant, making it suitable for sustained outdoor surveillance deployments in dusty, wet, and demanding field environments.
A heavy-duty aluminium tripod is supplied with a 200 kg load capacity, 10 kg weight, height adjustable from 720 mm to 1300 mm, two stages, swivelling feet, a spirit-level bubble indicator, and a mid-level spreader. It is JSS 55555 compliant.
The PTU is constructed from Aluminium Alloy 6061-T6 with a paint or powder-coated finish, providing a lightweight, corrosion-resistant structure for sustained outdoor field deployment.
