Product Description

DSLRKIT MID8P2U-E250 Passive PoE Injector Switch 

Support EXTEND mode, max Network Cable length to 250 meters

Power supply not included

Supports 12~55V DC power supply

(Maximum current 4 amps)


DC IN port 5.5X2.1mm, inside positive (+)  outside  negative (-)

10 Ports (2 Uplink, 8 PoE) 10/100Mbps

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

Wall Mount


NOTE. When EXTEND mode enable, the Max bandwidth for the Power Link (PoE) port 1-8 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)

If you switch to the EXTEND mode, the Max allowable Network Cable length will increased to 250 meters. Then suggested buy 52V power adapter. This will avoids the power loss over the long distances, and will make sure the PoE IP Camera working.

This item do not include the power adapter,  you need to buy an extra power adapter according to your requirement. So it only suitable for PoE professional customers.

Please select the correct Power adapter by POE device,
802.3af (802.3at Type 1) PoE device, We suggest DC 48V power adapter.
802.3at Type 2 PoE+(plus) device, We suggest DC 52V power adapter.
Please refer to the Wikipedia "Power over Ethernet" section, under the "Standard implementation" paragraph. 

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



This is an Passive Power Over Ethernet of 10 port 10 / 100Mbps-T Ethernet switches, including 8 unsolicited PoE Ethernet ports and 2 Uplink ports. DC port apply 12~55V power supply adapter(not included), any one of the 8 port can provide output power, each Ethernet port can provide network transmission speeds of up to 10 / 100Mbps , with Cat5 / 5e / 6 network cable.

This POE switch only support 10/100M connection, PoE ports do not support Gigabit ethernet connection, because  "Power Link 1~8" 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 1~8" port, this will damage your device.

Gigabit(1000Mbps) ethernet Uplink device can only access "Up link" port, Please do not access "Power Link 1~8", this will damage your device.
