Theia Technologies

• High quality optics

• Added variety– Wider angle lenses– Unique no fisheye distortion lenses– Day/Night megapixel lenses

• Innovation in optical design

• Offering Theia’s unique lenses helps you sell (megapixel) cameras


April 10, 2023

Linear Optical Technolog®

• Ultra wide lenses without distortion– Rectilinear design

• Designed in the USA – Patented

• Manufactured by our Japanese partner

• Image is inverted– Switch image orientation in

camera software


April 10, 2023

Optical distortion correction

Typical wide angle lens• All other security lenses with fields of

view greater than 80°have barrel or “fisheye” distortion

• Resolution is reduced as the object moves farther from the center of the image

Theia’s rectilinear lens• Rectilinear lenses keep straight lines

straight• Resolution is increased as the object

moves farther from the center of the image

Both images taken with a 5mpix camera at same distance

Optical distortion correction

Typical wide angle lens• All other security lenses with fields of

view greater than 80°have the well known barrel distortion called fisheye distortion.

• Resolution is reduced as the object moves farther from the center of the image.

April 10, 2023

Theia lenses

• SY125– Up to 135° HFOV

• 40% more FOV than the SY110 lens

– Multi megapixel resolution

– auto-iris or manual iris– CS or C mount

• SY110– Up to 120° HFOV– IR corrected for

Day/Night cameras– Multi megapixel

resolution– auto-iris or manual iris– CS or C mount


April 10, 2023

Recommendations• SY110

– Recommended for VGA/ high res to 3MPix*– Recommended for Day/Night cameras

• SY125– Recommended for 1.3MPix to 5MPix– Not recommended for Day/Night cameras– Day camera at night with ample visible light

• List of enclosures on Theia’s website– www.TheiaTech.com/accessories.html

* May be used with 5mpix as well


April 10, 2023

New Theia lenses• SL1.8-3 Wide Varifocal

– Linear Optical Technology®– Up to 115° HFOV*– True zoom™– 5 Megapixel resolution– IR corrected for Day/Night

cameras– auto-iris or manual iris– CS mount– 50mm long, slip ring– Production 12/10

• SL9-40 Telephoto– 7° to 36° HFOV*– 5 Megapixel resolution– IR corrected for

Day/Night cameras– auto-iris or manual iris– CS mount– 50mm long, slip ring– Production Jan. ‘11


* Depending on sensor size

3D stretching

• Rectilinear lenses create 3D stretching– Objects in the same plane are the same width– Objects with depth appear stretched

• Increasing number of pixels on the object

Considerations:

•Camera resolution•Lens FOV•Camera distance from subject•Camera height•Image resolution•FOV coverage•Camera/lens position, angle


Benefits

Better Image Quality

April 10, 2023

Same area of the image with Theia’s lens shows increased

image edge resolution

•High quality multi-megapixel optics provide a clear image•Improved image resolution at the edges of the image•Increases the likelihood of recognition and identification•SY110 maintains focus in IR illumination

Lens with barrel distortion shows decreased resolution

Both images taken with 3mpix


Benefits

April 10, 2023

Same coverage requires 18 high res camera with (typical) 4mm lenses

Complete perimeter coverage with 8 Theia lenses and megapixel cameras

Lower total cost of system ownership•Ultra wide HFOV reduces the number of cameras required

•Saves money on installation, maintenance, and monitoring•Multi megapixel lens resolution allows use of up to 5MPix camera

•Digital PTZ eliminates the cost of installation and maintenance of mechanical PTZ


April 10, 2023

Benefits

More convenient system to use•Real time, all optical distortion correction•Eliminates the need for dewarping software – no extra step•Straight lines remain straight in the image - easier for operator to monitor, less fatigue•Monitor wider area on one screen/window
