LAB 3 ( ps-2)
phsyical security
Objective
Select the appropriate lens for a video surveillance
system design.
Background
The choice of camera lens is very important in the
security design in order to ensure appropriate image
quality being captured. The lens parameters, like
focal length, field of view, aperture, are dependent
on the scene environment.
Procedure
1. Consider that you are designing the video
surveillance system for the parking lot of an
apartment building in a downtown.
2. Follow the steps below and use the tables in the
text book to determine the lens parameters you
would need.
a. Choose the sensor format (1/4- 1/3- ½2-ich)
b. Assume the distance from the camera to the
scene (parking lot to monitor)
c. Assume the size of the scene
d. Find the focal length of the lens
e. Determine the angular
f. Determine the size of the sensor
g. Determine the lens-sensor magnification, monitor
magnification (assume a 19-inch monitor) and overall
magnification.
