For long range surveillance applications with large and heavier composite payloads, the Mantis is Instro's high capacity motorised pan and tilt.

Available in 'L' and 'U' configurations with a slipring assembly as standard, Mantis can be configured to handle an impressive range of sensors and sensor suites. The superior payload capacity of the Mantis makes it suitable for long range coastal and port authority surveillance installations as well as stabilised Naval applications.

The backlash free design is suited for applications requiring high positional repeatability for preset watch points, typical of port authority and critical infrastructure installations. Mantis is also rugged and capable of deployment on heavy wheeled and tracked vehicles for observation systems requiring a high degree of controllability and positional accuracy. With the addition of a tripod mount adapter, the Mantis is equally suited to ground deployment on a tripod such as the Instro Groundmaster.

The Mantis 'U' configuration includes a support arm which increases payload capacity and enables adaptation to wider, bulkier payloads by addition of custom spacer blocks to achieve optimum payload mass distribution.

The capabilities of the Mantis motorised pan & tilt can be further extended with factory configured options for gyro stabilisation, automatic video tracker, digital image stabiliser and marine grade environmental finish.
