TH8 POE Injector Quick Installation Guide

About

This guide covers the the installation procedures for connecting a 12 V or 48 V POE (Power Over Ethernet) 

injector kit to a TH8 recorder. 
A POE injector kit lets the TH8 recorder connect up to 2 additional IP cameras via its expansion ports. This 

increases the recorder’s maximum channel count from 8 to a potential 10.
Note that the 12 V and 48 V POE injectors kits are separate, distinct products. This guide covers the installation 

procedure for both kits. Ensure that you are following the proper installation procedure for your kit.

Pre-requisites

Before proceeding with this document, you must first have a 

TH8 recorder with FW 2.0

 or higher installed and 

functioning in a vehicle. Do not proceed with this document if you still haven’t installed the TH8 recorder. The 

TH8 Installation Guide (Part #: 700-1123) can be found on the Safe Fleet Community (community.seon.com/
