[. . . ] (WJEC) was retained by Opticom Technologies Inc. to perform a set of vibration tests on its Model CC-02-4. 3 CCTV camera. The primary objective in testing the camera was to verify its structural integrity. [. . . ] This was done by subjecting the unit to the worst-case vibrational stresses expected in its application environment. The testing consisted of vibrating the Model CC-02-4. 3 CCTV camera in the two mutually perpendicular axes in accordance with the profiles defined in Sections 4. 9 of the SAE J1455 (August 1994) Standard and Method 514. 5 of the IR-4714 (January 2000) Standard. The testing of the camera was performed on June 14th and 15th, 2005. 2. 0 VIBRATION PROFILES The vibration testing of the Model CC-02-4. 3 CCTV camera comprised of subjecting the unit to the Sinusoidal profile as defined in Section 4. 9 of the SAE J1455 (August 1994) Standard and to the Random profile as defined in Method 514. 5 of the IR-4714 (January 2000) Standard. The parameters of the Sinusoidal and Random profiles are summarized below with the graphical representation of the Sinusoidal profile shown in Figure 1 and that of the Random profile shown in Figure 2. Sinusoidal (truck chassis-mounted) Amplitude* - 2 G's from 10 to 12 Hz 2. 5 G's from 12 to 14 Hz 3 G's from 14 to 16 Hz 3. 5 G's from 16 to 18 Hz 4 G's from 18 to 2, 000 Hz Sweep rate - 0. 5 octave per minute Duration - 180 minutes per axis for each axis. Unit to be operational as intended during testing. * the step function is intended to simulate the ramp-up from 10 to 20 Hz. 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 Red Dark Blue Light Blue Description Frequency limits and Upper and lower limits of acceleration. Shaker output as measured by the feedback accelerometers. 5 30144-REP-001-0. wp9 Weir-Jones Engineering Consultants Ltd. Based on the graphical results, it can be seen that the shaker outputs as measured by the feedback accelerometers corresponded with the defined Random vibration profile within the allowable tolerance specified by Method 514. 5 of the IR-4714 (January 2000) Standard. Because the Model CC-02-4. 3 CCTV camera was rigidly mounted onto the mounting fixtures during the testing, the camera was therefore subjected to the same vibration profiles as those generated by the shaker.
