When connecting your IP cameras to an XVR you will need to follow a few prerequisites. Once you have an understanding of the below steps you will be well on your way to adding all of your IP cameras to your security DVR. You will need a PoE switch, a router, a Windows PC, IP camera(s), and XVR.Connect the PoE Switch1) You need to have a PoE switch that is 802.3af/at compliant to power your IP cameras.2) Connect the PoE switch to your router to make sure it is connected to the network.3) You need to connect the DVR to one of the ports on the switch or router. If your PoE switch has multiple uplink ports (non-POE), we suggest connecting the DVR/NVR to one of the uplink ports.4) If you have lights on your switch, make sure the lights for the ports you just connected are lit. Each port will be numbered according to the port you have connected.Configure DVR to your network5) Configure the DVR to an IP address that is compatible with your network. If you don't know how to do that, you can follow our guide on how to connect security cameras to the internet to learn simple networking concepts to properly deploy a DVR or camera on a network.6) It is important to configure networked devices to proper IP addresses based on your local network (LAN) for them to communicate to each other. A common network structure is 192.168.1.xxx but yours may vary.7) We suggest changing the IP address of the recorder to something other than the default 192.168.1.108 so there is no conflict with any new IP cameras you purchase from us. All devices we carry come with a default factory set up address of 192.168.1.108.Configure cameras to your network8) Connect your IP cameras to the PoE switch and configure them to an IP address that is compatible with your LAN. For the guide on how to configure cameras follow our guide on How to Assign an IP Address to your IP camera. If the camera does not allow you to change the IP address then it may need initialization. A video guide for initialization can be found in section 1D in our guide on How to Connect an IP Camera to a Computer. Repeat this step for each IP camera that you intend to connect to your Tribrid DVR.Add Cameras to your XVR over the network9) After you have configured the recorder and the cameras on the network you need to configure the XVR to accept IP camera channels. This requires you to enable adding IP cameras, and change the channels to IP camera channel type. Below is a comprehensive video guide on how to enable and modify channels to connect IP camera and then adding an IP camera.How to Add IP Camera Inputs to a Tribrid DVRIf you are still having a problem, then it's necessary to check the IP addresses of both devices. If they are the exact same then the camera will not appear. The same is also true for devices that are not properly configured to be on the same network. Make sure you fully understand the concepts above before attempting to configure your system to accept IP camera channels.
