PoE & Non-PoE Switches
You have 2 choices when it comes to network switches, PoE or Non-PoE.
PoE (Power Over Ethernet)
PoE switches offer the easiest installation solution as they power the camera over
the network cable so a single cable caries the power and data.
Non PoE
Non PoE switches only carry the data down the network lead so you would still need
to power the cameras locally.
PoE Range
Traditionally PoE works on cable runs up to 100m. You can, however, achieve
greater distances using PoE extenders if required.
PoE extenders boost the PoE range an additional 100m. You can use up to 2 single
channel PoE extenders on a cable run for a maximum PoE range of 300m. PoE
extenders are passive so they don't require any external power source.
Some PoE switches have built-in range extenders which can boost the PoE range up
to 200m without the use of an external PoE extender.
