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.

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

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
© Theia Technologies, 2009
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
