PoE Switch 8 PoE Ports plus 2 Gigabit Ports
10 port PoE switch with 8 ports PoE and 2 x Gigabit non-PoE ports which are normally used to link the NVR to the Power over Ethernet switch. IEEE802.3af standard PoE data and power transmission distance 100meters. Output power 15.4 Watts each port. Built-in power. size 140 x 91 x 28mm.
PoE switch with 10 ports, Power over Ethernet. 8 of which are POE and 2 ports as an uplink. Also works as a network switch.
What is PoE switch – Power over Ethernet?
Power over Ethernet – POE is a technology that lets network cables carry safe low voltage which is normally 48VDC power.
For example, an IP 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 12VDC power the camera that’s needed to operate
However, if the camera is POE-enabled, only the network connection needs to be made, as it will receive its electrical power from this cable as well. Nearly all of our IP cameras are PoE enabled which exception of some PTZ cameras.
Why use POE?
Power over Ethernet brings many advantages to an installation:
Time and cost savings – by reducing the time and expense of having power cabling installed. Network cables or CAT5 cables as they are commonly known as, do not require a qualified electrician to fit them and can be located anywhere.
Flexibility – without being tethered to an electrical outlet, devices such as IP cameras and wireless access points can be located wherever they are needed most, and repositioned easily if required.
Safety – POE delivery is intelligent, and designed to protect network equipment from overload, underpowering, or incorrect installation.
Reliability – POE power comes from a central and universally compatible source such as an NVR or a PoE switch, rather than a collection of distributed wall adapters. It can be backed-up by an uninterruptible power supply or controlled to easily disable or reset devices.
Scalability – having power available on the network means that installation of IP cameras and other network connections is simple and effective.
Devices that use Power over Ethernet
POE has many applications, but the three key areas are:
IP cameras– POE is now standard on networked surveillance cameras, where it enables fast deployment and easy repositioning
VoIP phones– the original POE application. Using POE means phones have a single connection to a wall socket and can be remotely powered down, just like with the older analogue systems.
Wireless – WIFI and Bluetooth APs and RFID readers are commonly PoE-compatible, to allow remote location away from AC outlets, and relocation following site surveys.
How to upgrade to POE
Adding POE to your network is straightforward, and there are two routes you can choose:
A POE switch is a network switch that has Power over Ethernet injection built-in. Simply connect other network devices to the switch as normal, and the switch will detect whether they are POE-compatible and enable power automatically.
POE switches are available to suit all applications, from low-cost unmanaged with a few ports, up to complex multi-port rack-mounted units with sophisticated management.
A midspan (or POE injector) is used to add POE capability to regular non-POE network links. Midspans can be used to upgrade existing LAN installations to POE, and provide a versatile solution where fewer POE ports are required. Upgrading each network connection to POE is as simple as patching it through the midspan, and as with POE switches, power injection is controlled CCTV Wholesales in single port as its commonly called a PoE injector.
Non-PoE devices can be upgraded to PoE powered devices, such as IP cameras, to by using a PoE splitter. The POE splitter is patched into the camera’s network connection and taps off the POE power, which it converts into a lower voltage suitable for the camera.
