THE CHALLENGE
A large defense company requested a remote visual solution suitable for long-range surveillance. The customer required outdoor IP cameras with HD resolution and a 30x optical zoom that could withstand harsh environments in a wide range of extreme temperatures, including both high heat and cold.
The cameras required a cold startup at an ambient temperature as low as -26° C, an operation that a standard outdoor camera would not be able to achieve.
Additionally, the camera needed to be IP-enabled to control over internet.

DEVELOPMENT & INNOVATION
The InterTest team selected the Sony FCB-EV9520L 30x LVDS Block Camera, which offers outstanding clarity with 30x optical zoom and 12x digital zoom. They paired this with the Z3 Technology Q603-15 Video Encoder for HD streaming over H.265/H.265 compression. This duo was the optimal choice; however, the minimum operating temperature for the camera and encoder is -5 °C.
A heating system needed to be implemented in an IP67 housing, along with a thermostat to accurately regulate the internal housing temperature. A reliable and adequate power source was also required to accommodate all of the components.

THE SOLUTION
InterTest engineers packaged the Sony FCB-9520L block camera with Z3 Q603-15 encoder board for this project, due to their combination of high performance, low latency, and reliability. The enclosure consisted of an outdoor IP67-rated housing to sustain performance in a wide range of environmental conditions.
The critical component was ensuring camera start-up and continuous operation in extremely cold temperatures. The final product includes two heaters built into each housing, drawing a mere 250-280mA of additional current, thereby enabling low power consumption and bypassing the need to add a second power line.
The final products were tested in a specialized freezer with a digital temperature preset, to ensure the cameras could withstand the temperature demands.
