1.0 INTRODUCTION
On June 10 , 2005 Weir-Jones Engineering Consultants Ltd. (WJEC) was retained by
th
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.

2.0 TEMPERATURE TEST EQUIPMENT
2.1 Test Equipment
The equipment required for the temperature tests was an environmental chamber
(see Figure 1). The specifications of the chamber are as follows:
Manufacturer: Envirotronics
Model: EVH33-2-705
Temperature range: -73°C to +177°C
Maximum transition rate: 7°C per minute
Controller: manufactured by Micristar
The controller for the environmental chamber was calibrated on April 1 , 2005 by TMC Services
st
Inc. in Elk River, Minnesota, using instruments there were traceable to NIST. The calibration
certificate of the controller is provided in Appendix 1.

In addition to the Controller providing both dry-bulb and wet-bulb temperature readings, two
external measurement devices were also used to display the ambient temperature inside the
environmental chamber and also the temperature of the unit under test. The two measurement
devices were:
• Fluke Model 80TK thermocouple module (S/N 6983158) for the display of the ambient
chamber temperature.
• Fluke Model 80TK thermocouple module (S/N 6983164) for the display of the temperature
of the unit under test.
The calibration certificates for the Fluke thermocouple modules are also provided in Appendix 1.
The outputs from the thermocouple modules were recorded by a HP 34970A data acquisition unit
at a sampling rate of one sample every five minutes.
2.2 Equipment Placement
The placement of the three Opticom CCTV cameras within the environmental chamber is
shown in Figure 2. An external video monitor is placed outside the chamber in order to view the
output from the cameras.

3.0 RESULTS
The graphical result for the temperature testing of the Model CC-02-4.3 CCTV cameras is
presented in Figure 3. Based on the temperature measurements it can be seen that the temperature
of the camera casing was cooled to -40°C at around 13:00 on June 10 and allowed to soak at that
th
temperature for approximately 3 hours. In addition, the temperature measurements also showed that
the temperature of the camera casing was cooled to -50°C at around 16:30 on June 10 and allowed
th
to soak at that temperature for approximately 45 minutes.
The functionality of the three CCTV cameras was verified and witness by David Boyd of
Opticom Technologies Inc. at the end of each temperature step by powering up the cameras and
viewing the video output on the external monitor. In both temperature extremes, each camera
powered up and provided video output to the external monitor. The results showed that all three
CCTV cameras can operate at -40°C and -50°C and therefore will likely operate even when
subjected to these temperatures for an external period.
