they have the swann 2 packs still available, i didn't see the lorex cameras last time, i'm not sure if costco would list the same camera from 2 oems at the same time?
Will the Swann cameras work in the Lorex NVR or do I have to flash the firmware?
Yes, no firmware update required. Simply login to the web interface of the Swann cam and change ip addressing from static to dhcp, then change the admin password to 000000
