Motorized 4k Telephoto: TL1250 -R

We are retiring 1250 -R versions in mid 2023 and replacing with 1250 -N versions. 1250-N versions have slightly larger focus/zoom motors, but the optics design is identical to the -R version.

  • Ultra high resolution, long distance telephoto lens
  • 12 - 50 mm focal range
  • True 4K, 12 megapixel resolution
  • Fully motorized with zoom, focus, iris. Some models include IR cut, and limit switches
  • IR corrected for Day/Night
  • For 1/1.7" sensor sizes or smaller
  • Compact design to fit into domes as small as 4” mini-dome size

Theia offers a downloadable Motor Temperature Calculator that estimates the temperature of focus and zoom motors after cycles of running and cool down.

For ease of evaluation of Theia’s motorized lenses we offer a lens motor control board. This can be controlled by USB, I2C, and UART connections. You will find more information about the Motor Control Board at the link shown.

Theia's TL1250 lens is designed to be very compact and better image performance compared to competitive products.  Despite the long focal telephoto focal length, this lens is designed for small 4" dome cameras and bullet cameras.  

Similar to Theia's other lenses, the TL1250 series 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 lens can be used on cameras up to 12 megapixel resolution giving a crisp image from edge to edge.  

The non-motorized version of the lens is the SL1250.
