Common networking problem for DVR systems.
Some customers complain that their CCTV cameras stopped working remotely after a power outage. When the power goes out, the modem/router and the DVR turns off. When the power comes back on the DVR takes little longer than some other devices that also might be on the network and are configured to get IP address automatically (DHCP). The other devices that have booted up before the DVR can sometimes get the IP address for the DVR.The DVR, which is usually configured not to get IP address automatically, is not able to get its IP address.There is a simple solution that might work for some people.Turn off all your devices on the network including your cell phones, any Wi-Fi device computers, credit card machines, etc.Now power on your router, then power your DVR on, since there is only one device connected which is your DVR, most likely the DVR will get the assigned IP back.When your cameras start working on the Internet remotely, you can start turning on the rest of your devices. If somehow this did not work for you, change the setting on your DVR to automatically obtain IP or enable DHCP. When you close the network window for the DVR and go back, you will see the IP address has changed.Now you can go back to your modem and change the IP address in the port forwarding setting under firewall. Some routers call it a virtual private server. There is only one rule of thumb when setting up a network for a DVR.The port forwarding setting on your modem/router has to match with the DVR. The IP address in the DVR cannot be different than the port forwarding setup in the router, they have to be the same.
