I just had and issue with a client where I ended up having to change the DHCP scope and network id. I have changed the DVR to match the network and then after that it is now prompting me any anyone else to tries to log into it or make any changes with an admin username and password and I know I did not configure it to do that. Also no one knows who this was purchased from which makes this even more challenging. I have reached out to a camera company to see what could be done and then he recommended that I do a firmware upgrade to default factory reset it and the website he directed me to did not have any firmware for that device. Does anyone know where I can either find a firmware update or somehow default factory reset it.
