INTRODUCTION

th
On June 10 , 2005 Weir-Jones Engineering Consultants Ltd. (WJEC) was retained by
Opticom Technologies Inc. to perform a set of temperature tests on three of its Model CC-02-4.3
CCTV cameras. The primary objective in testing the cameras was to verify their functionality at low
temperatures. This was done by powering down the units and cooling them to -40°C and -50°C and
verifying that they power-up and function properly at the two temperatures. The testing of the units
was performed on June 10 , 2005.
