Comparing Vision Technologies' pan and tilt cameras to a gimbaled camera
The Vision design was originated to accomplish the following:
(1) meet and surpass MIL-STD 901-D Grade "A" shock
(2) Vibration: MIL-STD-167-1
(3) Enclosure: NEMA 250-1997, Section 5.7
(4) Power: MIL-STD-1399, Section 300A
(5) Salt Fog: MIL-STD-810
(6) Temperature and Humidity: MIL-STD-810
Additionally the Vision P&T will pan as fast as 70º per second and as slow as .01º per second.
The pan is 360º continuous and the tilt is +90º and -90º; with lost motion no greater than 1/60 of a degree
one arc-minute).
The J-6 and J-8 cameras utilize a modular design architecture to build an integrated system of Line Replaceable
Units (LRUs) to meet mission-specific imaging requirements. For example, the Pan and Tilt LRU is designed to carry
as many as four sensors (or LRUs) that do not exceed the pay load limits listed below:
Optional image stabilization is available as either electronic post-processing of the raw image or real-time gyro
stabilization of the sensor itself. The combined design, ruggedization and stabilization capabilities of Vision Tech's P&T cameras surpass the capabilities of a gimbaled design for most military missions.
Gimbaled Cameras
Although gimbaled cameras have been used for years most have not been designed to meet and surpass all of the MIL Standards listed above.
We do not know of any gimbaled cameras that have been certified to meet the Navy's MIL-STD 901-D grade "A" Shock certification.
Additionally, unless the cameras are mounted upside down they normally have a +90º and a -45º tilt range.
Most of these cameras do have a 360º continual pan, however most if any have a lost motion as accurate as 1/60 of a degree.
The gimbaled cameras do have two axes gyro stabilization and some have Image stabilization as well however with the combination of the BARCO image stabilization and the Vision six axes gyro stabilization the Vision camera system is superior.
