Page 4: Introduction
On June 10 , 2005 Weir-Jones Engineering Consultants Ltd. (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. - Page 5 Blue - Vibration profile Red - Upper and lower limits of frequency and acceleration (equivalent to ±3dB) Figure 1: Graphical plot of the SAE J1455 Sinusoidal vibration profile intended for equipment to be mounted on truck chassis.

VIBRATION TEST EQUIPMENT The equipment required for the vibration tests was a shaker, a vibration controller and two feedback accelerometers (see Figure 3). The specifications of the equipment used are as follows. Shaker: Manufacturer: Ling Dynamic Systems (LDS) Model: V722 Rated Force: 750 lbf. - Page 7 As the vibration shaker was designed to translate in the vertical direction only, a set of Aluminum mounting fixtures were used to position the CCTV camera in its two mutually perpendicular axes (Vertical and Transverse) as shown in Figures 4A and 4B. Feedback accelerometers Figure 4A: Vertical orientation mounting of the CCTV camera.

RESULTS 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 Frequency limits and... - Page 9 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 U.S. Highway Truck Random vibration test in accordance with Method 514.5 of the MIL-STD-810F (January 2000) Standard.

It should be noted that the amplitude between 10 and 20 Hz had been increased slightly in order to compensate for the lighter weight aluminum fixture. The resultant shaker output however still matches with the required profile as defined by the MIL standard.
