PoE (Power Over Ethernet) technology brings new capability and device expansion to network deployments, such as IP cameras, indoor wireless access points, VoIP (Voice over IP) phone systems which are capable of receiving power over Ethernet cabling. Among them, VoIP phone is a fast-growing area for small and medium-sized businesses Read more…

Lightning is inevitable all over the world and it causes real trouble to all electrical and electronic devices. Also, the network devices are not safe from attack. Especially if you have a tower without any lightning conductor, your network devices such as the router or switch are prone to lightning Read more…

Uplink portThe uplink port refers to the port connected to the aggregation or core network. Usually, the interface rate is higher and does not support the POE function. The port iu marked with UPLINK is the uplink port, usually on the far right of the switch, 1-2 (some are 4 Read more…

The standard 48V poe switch can only provide DC44-57V voltage. It can’t directly power 12VDC camera or other 12VDC PD devices. We can use 48V to 12V POE splitter cable to power the 12VDC device.The POE splitter cable is to solve the problem that some powered devices do not support Read more…

PoE NVR and NVR without PoE are two NVR types on the market. They use different connection methods for IP cameras. Note that, it’s important to check the R supports, compatibility between the NVR and IP cameras when setting up NVR for IP cameras. First, make sure that the network Read more…

For better functioning, Ethernet switches need power. There are various energy sources other than the standard AC power that Ethernet switches use. As we know, AC is the most common solution most people use to power their switch. Most switches already come with a provision to connect the power supply. Read more…

一.Configuration Process of PoE Switch Setup with NVRGenerally, the PoE switches are integrated or configured with NVR for the following purposes.To reduce the complexity of the Ethernet video transmission network.To get more number of ports for transmission.To suffice these two requirements, the two types of configurations are done in the Read more…

PoE switch or power over ethernet switch is a network switch that applies Power over Ethernet technology. When connected with multiple network devices, PoE switch can support power and data transmission over one Ethernet cable at the same time which dramatically simplifies the cabling process and cut network cost. PoE network switch can Read more…

EW-S1926CG-AP 一.Here’s what the Ethernet port LED Indicator colors mean:1-26(Link/Act)/ (Green)When Blinking Ethernet light means that the port is transmitting information.Solid light means a connection between the devices.No light means that there is no current connection. PWR (Green)Solid light means power supply. 二.How To Install?After the POE is powered on, Read more…

POE : Power Over Ethernet refers to the use of IP-based terminals such as IP telephones, wireless LAN access points, and network cameras without any changes to the existing Ethernet Cat.5 cabling infrastructure. etc. The technology that can provide DC power for such devices while transmitting data signals is a switch that Read more…
