If the maximal power supply of the all your cameras exceeds your PoE switch power cap, then the PoE switch won't provide enough power for all your PoE IP cameras, pan-tilt-zoom (PTZ) IP cameras in particular. Meanwhile, the maximal power supplies of your PoE switch matters as well. Similarly, the PoE+ standard ( IEEE802.3at) can pump out up to 30 W per port while only 25.5W could transmit to Network-enabled devices in real time.Ĭhoose a PoE Switch that suits your surveillance needs and makes sure to double check your PoE IP camera power consumption ether in the user manual or technical specification spreadsheet. In practice, only 12.95 W will be supplied to the IP cameras or other PoE devices given the power loss that dissipates in the network cables. There are mainly two types of power over Ethernet (PoE) standards, theoretically, the PoE standard ( IEEE802.3af) could provide up to 15.4W of DC power on each port.
Therefore, a PoE switch should be able to provide enough power for different types of IP camera via Cat 5 or Cat 6 cables. PoE IP Camera Power ConsumptionĪ PoE switch not only carries network connection but also supply power to Power over Ethernet (PoE) IP cameras. However, IP cameras power consumption varies some could draw up to 20 Watt such as PTZ IP cameras RLC-423 while others could consume as little as 3 or 4 Watt. To choose a suitable, reliable and best PoE switch for your IP security cameras, there are few factors you need to consider: PoE standard, PoE IP cameras' power consumption, PoE switch maximal power supply, PoE switch port number, cable length and etc. How to Select, Choose or Buy a PoE Switch for IP cameras The question is how to choose or select a best PoE switch for your IP cameras. In such sense, a PoE switch provides power for all PoE devices, including IP cameras, computer, VoIP phone and other network-enabled devices.
What is a PoE Switch Used for IP CamerasĪ PoE switch, simply put, provide power supply and data connection to power over Ethernet IP cameras via a single network/Ethernet cable ( Cat 5, Cat 5e or Cat 6), similar to a PoE injector which normally supplies power and network connection to one IP camera.Ī PoE Switch normally comes with multiple ports to support more than two IP cameras. So today, we share some insights and help consumers choose and select a suitable, reliable and best PoE switch for IP cameras. The questions always go like this: How to select a PoE switch for my IP cameras? Should I go for or Gigabit PoE network switch for my IP security cameras? Do you have any recommendation on a PoE switch for over 4 IP cameras?
Every now and then, we are asked by consumers on how to choose, select and buy a PoE for their IP cameras.
