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 2 payload capacities, 5Kg or up to 14kg with the higher torque variant.

D1 pan and tilt models are available in both slip-ring and non slip ring configurations for cost sensitive applications and all can be tripod mounted for rapid deployment in homeland security and border surveillance tasks. An optional level bubble is available if required.

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.

Cable connections have been optimised for frequent tripod deployments and the possibility of cable wrap up has been eliminated by including the input connector within 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.
