How to deliver adequate power to security devices in industrial sites
How to deliver adequate power to
With security found in more and more industrial settings, advanced and heavyduty network devices are needed on the edge to make implementations effective. Amid this trend, the first major challenge is to deliver enough power to these devices. Increasingly, traditional PoE standards, IEEE 802.3af/at that deliver 15.4W and 30W of power, are proving insufficient in this regard. A hardened 60W PoE switch, on the other hand, can better the power supply needs of industrial users.
With IP technology, video surveillance systems have become smarter, and are now utilised across multiple applications and integrated with other systems. Power over Ethernet (PoE) technology has become widely deployed in order to support the high power requirements of security cameras, wireless access points, and other connected devices. However, the problem for the current industry is when cameras or other security devices that consume 50W of power or even higher are used, the installer has to use an injector, which is a separate piece of equipment that may create extra cost and reliability issues, not to mention the fact users often find it burdensome and inconvenient. The injector also needs an extra power source, which can be quite a hassle when space is constricted. In 2007, the IEEE introduced a new standard, 802.3at, that scales power delivery up from the 15.4W available under 802.3af to a more robust 30W. However, users are still looking for more: a cost-effective PoE solution that can deliver a full 60 watts of power. While the future 802.3bt standard promises to at least double the power available to end devices, some manufacturers have decided to move quickly to
Power over Ethernet (PoE) technology has become widely deployed in most urban cities, in order to support all electronics devices in stable operation and well connected over internet.
