Re: Setting Up IP addresses through Xfinity Modem & POE Security Cameras

With your access point at, your IP Address range would be something like Go to your online gateway, log in, and then go to Connected Devices, then Online Devices. Scroll down to the bottom of the columns to where it says Add Device with Reserved IP. Click on this and fill out the info, including selecting the fixed or static IP address you choose. For example, you could number your devices sequentially starting with the first at, next would be and so on. The alternative to a static IP is setting your wireless devises on DHCP which allows the gateway to shuffle IPaddresses around from time to time, such that at any given point, a particular device might have received an IP address of, then on checking a week later it may be set at by the DHCP program. and save, this is a static IP, that is it doesn't change periodically

Setting Up IP addresses through Xfinity Modem & POE Security Cameras

I am installing home security cameras using a switch & POE internet to a dedicated Xfinity internet PC Hard drive with 3rd party software as a DVR, through the Xfinity cable modem. As I connect and setup cameras, I need them to have there own permanent IPv4 addresses and IPv4 Default Gateway number to be recognize in Xfinity gateway device page. Can I get the IPv4 address range of numbers best to be used with my Xfinity cable modem's gateway, so they are setup correctly. At the moment, I have one camera running at IPv4 address (camera default) with a IPv4 gateway number of through Xfinity modem.
I want to be sure to enter IP addresses correctly for each camera setup in my Xfinity internet gateway device page listing. Port forwarding the cameras later on for viewing them off site from a remote or cell device.
