Protect PoE Devices from Power Surges and Other Disruptions

Outdoor PoE CamerasFirst introduced in 2003, Power over Ethernet (PoE) has made installing equipment in remote locations convenient and affordable. One single Ethernet cable can deliver both DC power and data to low power PoE-enabled equipment, including IP security cameras, network access points and switches, and building access controls.

PoE was originally developed for IP phone systems and delivered only 7W of power. Over time, the technology has improved and can now accommodate up to 90 watts / 57 volts. PoE eliminates the need for additional (and more dangerous) A/C power wire runs to end-point devices.

Outdoor PoE devices are exposed to weather-related surges

While most Ethernet cable is relegated for indoor use, more and more outdoor systems are utilizing PoE due to its ease of installation and operation. The downside is this exposes PoE devices to the risk of power surges or spikes caused by weather conditions, including lightning strikes and other disruptions.

Like any electronic system, PoE devices and their internal components operate within specific current and voltage ratings. Excess current or voltage can damage delicate internal components.

Cracking the Codes - for Everyone's Protection

Crack the CodeBuilding Codes, Fire Alarm Codes, Electrical Codes – these aren’t meant to be secret codes, but there’s no question that it is difficult for lay people to keep up with all of them as well as their applicability, their changes, and their specific requirements. We need to know how to crack the codes!

Well, DITEK is here and ready to help with at least one aspect of this challenge – we can highlight a range of current codes that involve electrical surge protection, and we can go further if you need help evaluating your facility for adequate and effective Surge Protective Devices (SPDs). In the sections below, we refer to specific code requirements so that you can go directly to the applicable information regarding SPDs. Here is our version of a decoder ring to help get you started:

How State and Local Government Benefits from Surge Protection

Government municipalities benefit from surge protectionState and local municipal governments are where the rubber meets the road in terms of public policy, basic education, court systems, transit and a wide range of protective services including fire departments, police, and social services. It would be difficult to overstate the importance of these activities in maintaining a functional and civil society; yet in many areas, municipal governments remain in an endless process of prioritizing and reprioritizing purchases and services to address their objectives while never quite having enough resources to cover all the activities they would like to provide.

This difficult situation is only made worse when electronic equipment doesn’t last as long as it should, or when a key system is knocked offline or out of service by an unexpected equipment failure. Unplanned equipment expenses are bad enough, but the downtime and extra costs incurred until these systems are restored can place municipalities at risk; especially if video surveillance, access control and fire alarm systems, or emergency call centers are out of service.

A Power Strip is not always a Surge Protector - Here's Why

DTK 8FF blog2Imagine you are the manager for a large office building and want to replace your outdated lock-and-key system with a new access control system.

You have done the research and found the perfect keyless system that will protect the external entrances, elevators and individual offices. You have a company come in and set the system up, and within a few hours, the system is active and functioning properly.

Two days later a lightning strike triggers a power surge that damages your system, rendering it useless. No one can enter the building and those who are already inside cannot use the elevators or enter their offices. Bypassing the building’s security system gets everyone back to business, but also introduces a major security risk.
