New Jersey Electric Company Selects Perle PoE Solution for Surveillance Cameras
Tuesday, January 25, 2022 | Comments

The State Electric Company (STELCO) in New Jersey deployed Perle power over Ethernet (PoE) industrial switches in its substations.

Outdoor security cameras are designed to operate in sun, heat, rain, sleet and snow. The rest of the system, such as the switch, router, and power source, needs to be protected against the elements. Therefore, when STELCO decided to install security cameras at 50 substation and transformer locations, it knew it would need industrial-grade networking equipment housed inside IP65 National Electrical Manufacturer Association (NEMA) enclosures. When choosing equipment for this type of environment, there were several factors they took into consideration.

Many commercial-grade networking devices rely on airflow to dissipate heat generated by internal components. However, because IP65 NEMA enclosures are unvented, the equipment inside must be rated to operate in temperatures of -40 to +75 degrees Celsius.

The cameras are mounted on poles, or the sides of buildings, at the various substation and transformer locations. Therefore, the Industrial PoE Switches needed to provide PoE to the security cameras, as well as copper ethernet to single mode fiber conversion for data transmission between the cameras and recording stations at corporate headquarters.

“We selected the Perle IDS Switches as they met the operational connectivity requirements and could provide power to the surveillance cameras,” says Hassan Shifaz, network engineer at STELCO. “As the switches are fan-less and support high temperatures, the conditions within the NEMA enclosure prove no challenge to them. They are working well.”

Each Perle IDS industrial PoE switch provides 30 watts (W) PoE to the attached IP camera and performs copper to fiber conversion. Their small form-factor ensured easy installation into the compact NEMA enclosures. Unused Ethernet ports are designated for future surveillance expansion with additional cameras, motion detector devices and other equipment.

Perle industrial PoE Switches operate in temperatures of -40 to +75 degrees Celsius. All components are temperature rated and fully heat chamber tested. No ‘commercial-grade’ parts are used as these are likely to cause failures when exposed to high or low temperatures.
