 DSLRKIT MID4P2U-E250 Passive PoE Injector Switch  

 Support EXTEND mode, max Network Cable length to 250 meters

Suitable for Hikvision,DAHUA and other brands with 802.3af/802.3at PoE Powered Devices(PD)

NOTE. When EXTEND mode enable, the Max bandwidth for the Power Link (PoE) port 1-4 network port will be reduced to 10Mbps for each one. Please check your IP CAMERA's  bit stream setting. We recommend the value does not over 8Mbps(8192Kbps).

(The up-link is not affected, it will always working at 100Mbps max speed)

6 Ports (2Uplink, 4 PoE) 10/100Mbps

Midspan Mode-B Unsolicited Power(4,5+/7,8-)

Compatible IEEE 802.3af/at, Per port Max 50Watt

Wall Mount

52V 75Watt(Max.90W)
(If you switch to the EXTEND mode, the Max allowable Network Cable length will increased to 250 meters. So we use 52V power adapter. This will avoids the power loss over the long distances, and will make sure the PoE IP Camera working.)

(Please select according your device power consumption, in order to ensure device stable running, the total power consumption should not exceed 75watt of the power supply)

If your camera is with word “12V/PoE” as this picture shows, then please select this 52V PoE Switch, do not select 12V PoE Switch. 
Because "12V/PoE" means it can offer power supply to camera via 12V DC port or 48V(or 52V) PoE Ethernet port.




This This is an Passive Power Over Ethernet of 6 port 10 / 100Mbps-T Ethernet switches, including 4 unsolicited PoE Ethernet ports and 2 Uplink ports. With an external 110V-240VAC to 52VDC power supply adapter, any one of the 4 port can provide output power, each Ethernet port can provide network transmission speeds of up to 10 / 100Mbps , with Cat5 / 5e / 6 network cable.

Which compatible with IEEE 802.3af/at Mode-B(4,5+/7,8-) POE switch device, but it does NOT include the 802.3af/at compliant detection feature.  It supplies power NO MATTER WHAT, so don't plug the "Power Link 1~4" side into anything that isn't ready for it.

This POE switch only support 10/100M connection, PoE ports do not support Gigabit ethernet connection, because  "Power Link 1~4" port using 4,5,7,8 pin as power transfer, Please do not connect any "NONE PoE gigabit ethernet device and Uplink device" on "Power Link 1~4" port, this will damage your device.

Gigabit(1000Mbps) ethernet device Please do not access "Power Link port" this will damage your device.

Compatible all 802.3af/at device as Wireless Access Point, IP Phone, IP camera, Gateway , Switch, or More.....
