RESULTS
4.1
Sinusoidal Vibration Test
The graphical results of the Sinusoidal vibration tests for the Model CC-02-4.3 CCTV
camera are shown in Appendix 2 located in the back of this report. The interpretation of the lines
on each graphical result is as follows:
Line Colour
Description
Red
Frequency limits and
Upper and lower limits of acceleration.
Dark Blue
Vibration profile.
Light Blue
Shaker output as measured by the feedback accelerometers.
Based on the graphical results, it can be seen that the shaker outputs as measured by the
feedback accelerometers corresponded with the defined Sinusoidal vibration profiles within the
allowable tolerance specified by the SAE J1455 (August 1994) Standard. Because the Model CC-
02-4.3 CCTV camera was rigidly mounted onto the mounting fixtures during the various Sinusoidal
vibration tests, the camera was therefore subjected to the same vibration profiles as those generated
by the shaker.
The following observations with respect to the CCTV camera were made during and after
the tests:
•
No physical damage to the housing of the camera was noticeable during or after the tests.
•
No loose components within the camera were noticeable during or after the tests.
•
No degradation in the quality of the video produced by the camera was noticeable during or
after the tests.
Therefore the Model CC-02-4.3 CCTV camera has passed the chassis-mounted Sinusoidal vibration
test in accordance with Section 4.9 of the SAE J1455 (August 1994) Standard.
4.2
Random Vibration Test
The graphical results of the Random vibration tests for the Model CC-02-4.3 CCTV camera
are shown in Appendix 3 located in the back of this report. The interpretation of the lines on each
graphical result is as follows:
Line Colour
Description
Red
Frequency limits and
Upper and lower limits of acceleration.
Dark Blue
Vibration profile.
Light Blue
Shaker output as measured by the feedback accelerometers.
