Theia's motorized telephoto: TL936

Theia's 4K compatible varifocal telephoto lens can be used for long distance surveillance and license plate recognition.  This motorized version of the SL940 lens includes focus and zoom motors, IR cut filter, and photo interrupter limit switches for the focus and zoom ring positions.  It is designed for sensors such as 1/2.5" 5MP and 1/2.3" 4K resolution.  This compact lens is designed to be built into dome and bullet cameras.  Motors allow the user to remotely zoom and focus for optimal image quality without any physical interaction with the lens.  

Similar to Theia's other lenses, the TL936 is a high quality lens designed to allow the installer to take full advantage of the high resolution of 4K resolution, HD, and multi megapixel cameras. The excellent IR correction allows this lens to be used with IR illumination without the need for refocusing the camera when switching to night mode.

Motorized Lens Disclosure:


Please be aware that our motorized lenses are intended for integration into cameras and require motor drivers and controllers.  Typically Theia works with the camera manufacturer to ensure that the camera motor controller matches the lens.  We are worried that you or your customer may not know how to operate these lenses.   


It is possible for you or your customer to supply your own motor controller, but Theia cannot guarantee that your motor controller will not damage the lens.   Theia does not offer any warranty on the suitability of these motorized lenses for any particular camera.  For example, the connectors are not common for all cameras and may not work for yours.  These motorized lenses are not intended for continuous use of the motors as in PTZ applications.


Theia motors are step tested over the full zoom and focus range to be within an acceptable tolerance.  Theia cannot guarantee that zoom or focus set by the user can be mapped to a particular step within the range.  


Theia now offers motor control boards that are suitable to control only P-iris lens versions (see the lens specification for the relevant models).
