The D1 is a lightweight high performance family of motorised pan and tilt heads developed for general purpose surveillance applications.The D1 is a lightweight high performance family of motorised pan and tilt heads developed for general purpose surveillance applications.

Based around a rugged and compact casing, the lightweight D1 is designed to support payloads such as thermal imagers, day / night cameras and combination EO sensor systems. Depending on application requirements, D1 supports a choice of payload capacities, 5kg if it is top mounted and 9kg for pannier mounted.

The D1 pan and tilt is available with slip-ring as standard and can be tripod mounted for rapid deployment in homeland security and border surveillance tasks. All models feature an integral levelling bubble.

Payloads can be either top mounted using Instro's quick release wedge interface or installed side in a pannier configuration using a suitable dual payload mounting bracket.

Optimised cable connection eliminates the possibility of cable wrap up by including the input connector into the azimuth mounting base.

Internal cable connections pass power and communications through to a connector on the main body of the unit to enable easy connection to the payload.

Motorised Pan and Tilt

Instro's motorised pan and tilt units are characterised by high performance designs with milliradian accuracy and repeatability for precise remote control of camera and sensor payloads. With payload capacities up to 100Kg and variants suitable for land, sea and vehicle use, Instro's platforms offer an economic solution for a wide range of security, surveillance and positioning applications.

For systems requiring additional capability, factory fitted configuration options include:

•Gyro Stabilisation, to automatically maintain sensor line of sight in the presence of disturbances

•Digital Image Stabilisation, to electronically remove high frequency video jitter

•Auto Tracking, to automatically follow moving objects in the field of view

•Marinisation, to protect the pan and tilt from the harsh environment of marine and coastal applications

When observing on the move, Instro's latest D2 platform has the dynamic performance to suit integration on fast patrol boats and vehicles and equip them with HD quality streaming digital video at gigabit speeds.

Control of Instro's motorised platforms is either by using Instro's standard serial RS-422 interface, or on selected models via Ethernet.
