EwindPoE injector is a cable while transmission of electricity and data, first-line dual-use, very convenient and quick. Advantages of PoE Injector：1, since each device requires only a set of connections, the wiring of each device is simpler.2, eliminates the AP socket and adapter, so that the work environment is safer, more Read more…
Although PoE compatible switches exist, many homes, offices, and businesses have non-PoE switches already installed. Evidently, replacing the millions of non-PoE compatible switches is not a viable solution, now is unnecessarily running two cables – one for power and one for data – to a device that could be operated Read more…
The standard POE power supply voltage is set to 48V. The power supply voltage ranges from 44 to 57V. If the voltage on the supply side is not enough, or if the voltage is 40V, the transmission distance of the data signal will be greatly reduced, maybe only 30 or Read more…
24-Port Managed PoE Switch: A Must-have for Your NetworkThe demand for network performance is expanding with frightened velocity. Sometimes the use of a “dump” unmanaged PoE switch fails to meet network administrator’s expectation to manage and monitor the system. Thus, even most small and medium sized businesses are moving to fully managed Read more…
POE switch is divided into fan switches and fanless switches. Whether POE switch have noises depends on whether it has fan inside. Switch with fan inside relies on active cooling and heat dissipation. The use of the fan can quickly conduct the internal heat of the switch and dissipate it Read more…
Are all POE switches auto-sensing? The answer is No. Not all POE switches have auto-sensing PoE ports. As we know, some POE switches are standard, some are non-standard. So we need to discuss it on different situations. If it’s standard POE switch that supports IEEE802.3AF, IEEE802.3AT, and IEEE802.3BT, then all Read more…
1.First, make sure that the network video recorder supports the IP cameras that you intend to use.2.Second, make sure the NVR supports the resolution of the cameras because not all NVRs support 4K security cameras or 12MP cameras at present.3.Once the camera’s resolution is higher than the resolution that the Read more…
A PoE switch provides power that can be used to run other devices via the Ethernet cabling.If your network has distributed switches,it’s also possible to get PoE pass-through switches.These are themselves powered by PoE from a central source but can also pass power on to endpoint devices such as cameras Read more…
Power over Ethernet (POE) is a technology that lets network cables carry electrical power.For example, a digital security camera normally requires two connections to be made when it is installed:A network connection, in order to be able to communicate with video recording and display equipment A power connection, to deliver the electrical Read more…
IEEE 802.3af/at/bt compliant PoE technology is safe. PoE injectors and poe switches will not damage any equipment, even if the equipment is not designed for PoE applications. Before the PSE sends any power to a connected PD, the PSE initiates a handshake procedure that establishes how much power the connected Read more…
