Rugged outdoor pan-tilt system delivers precision, power and speed.

Directed Perception : 17 March, 2008  (New Product)
Directed Perception's PTU-D100 family of computer controlled pan-tilt units' features a compact, rugged all-in-one design and has flexible mounting options for single, or multiple payloads including video cameras, lasers, antennas, and thermal imagers.
The PTU-D100 is a low-cost, mid-range intelligent pan-tilt system suitable for fixed and mobile applications in military and industrial markets.

Built-in dynamic control capabilities include on-the-fly speed and position command changes at over 60Hz supporting a wide range of applications including real-time tracking. An available software API supports integration with custom applications. Geo-pointing and stabilisation options are available.

The PTU-D100 provides a complete set of features available in a cost effective package to address a wide range of modern sensing and communications applications that require real-time pointing of cameras, antennas, and other sensors.

Applications include airborne surveillance cameras and communications, shipboard day/night vision systems, military and police ground vehicle camera systems, border and perimeter surveillance, intelligent video surveillance, force protection systems, industrial automation, and scientific R&D applications.

The integrated design of the PTU-D100 provides a complete turn-key positioning solution for fast, accurate, dynamic, computer-controlled positioning of pan and tilt through a wide range of motion. Sensor and communications systems designers can save months of product development time by using the PTU-D100 as a complete, drop-in positioning solution.

The accuracy, high speeds, and dynamic control capabilities of the PTU-D100 enable applications such as long-range automated detection and tracking, which were previously difficult or impossible to implement in a cost-effective manner.

In the past, high-performance pan-tilt systems have been custom-designed for a specific application. This drives up costs, and reduces availability. Military and industrial customers require proven COTS solutions that can be put to work immediately without large engineering costs. The PTU-D100 meets that need.

"We began looking for a partner to provide pan-tilt subsystems early in development of the Discoverii platform. We found that Directed Perception offered a complete range of size and price/performance options that also met our important requirements for accuracy, durability, and reliability. The performance of the PTU-D300 and PTU-D100 products have exceeded our expectations and the Directed Perception team provided outstanding support during our entire development and product introduction process," said Chris Ruttle, CFO/COO, VUMII.

The patent-pending mechanical design uses worm gear design for superior dynamics and rigidity - no belts or pulleys. Specific performance features include:

* Payload capacities of 25lbs (side mount) and 15lbs (top mount)

* Fully controllable pan and tilt speeds ranging from below 0.0075 degrees/second to 120 degrees/second

* +/- 0.0075 degrees positioning resolution in both pan and tilt axes

* 360 degrees continuous pan with internal payload wiring

The PTU-D100 includes a fully-integrated controller with digital commands for fine-grained control of speed, acceleration, position limits, and power modes. Unit can be commanded in terms of either position or velocity and allows on-the-fly command changes to support dynamic tracking applications. Both RS-232 and RS-485 interfaces are built-in and an Ethernet option is available. Control software interfaces available include a LabView driver and a C source-code API for use with embedded or desktop CPUs.

The PTU-D100 is constructed of anodized machined high-grade aluminum and provides a sleek, integrated package with flexible payload and pan-tilt mounting options. Packaging features include:

* Rugged all-weather design (IP67) with wide-range operating temperature (-30° to +70 derees C)

* High duty cycle design (3 to 5 million cycles)

* Single 9-30VDC power input

* Single MIL-style connector for all signals and power. Pass-through of payload signals including power, video, and serial control.

* Compact size (11.2 x 7 x 7.9inch not including payload bracket)

Designed for easy customisation for advanced OEM applications

The PTU-D100 has a number of design features to support rapid customisation to meet specific OEM requirements. Customisation options include changes in: payload connectors/cabling, mounting brackets, slip-rings, encoders, and network interfaces.

The PTU-D100 is available now and US pricing is $5900 (Quantity 1) for standard configuration.
