As we all know, different PoE injectors have different compliant and will provide different voltage and current, then many people will have some questions that will the big voltage and current damage my PD devices? Or what if my security camera is not a PoE camera?
IEEE 802.3af/at/bt compliant PoE technology is safe of course! PoE injectors and switches will not damage any equipment, even if the equipment is not designed for PoE applications!
Each standard IEEE 802.3af/at/bt PoE injector has a detection chip inside the injector, before the PSE sends any power to a connected PD, the PSE initiates a handshake procedure that establishes how much power the connected device requires. This procedure uses low voltage and is harmless to any connected device, PoE or non-PoE. If the handshake is completed, the PoE injector or switch begins sending power, which triggers the PD to start up. If that handshake is not completed for any reason, the PSE never sends any power. It is this built-in feature of all IEEE 802.3af/at/bt-compliant devices that makes PoE technology inherently safe.
All Procet PoE injectors are totally compliant with IEEE802.3af/at/PoE++/bt, our factory has got ISO 9001:2015, ISO 14001:2015, OHSAS 18001:2007 Certification. All the PoE was designed based on CE/FCC/CCC requirements, part type past cUL/UL, SAA, PSE, BIS, KCC, RCM, NOM certification. High-quality PoE injectors ensure your equipment is safe all the time.
