Okay, going to post an update on this. So again, as above, the OID that is listed with the device is pulling some info. The weird thing is, if I try an snmpwalk from a linux server against that camera, I get no response.
However, if I run the snmp walk using an OID I got from Cisco, I do get the Serial number among other things. I used the Device Tester and it comes back with the OID that doesn't work from snmpwalk, so I'm a little confused how it is returning values. In any case, is there a way to override?
