Update - Received, installed (eventually) and working fine, however , for anyone thinking of going the same route, one BIG caveat! Password for installation. The Eufy requirement is totally specific in respect of size and makeup. No less tha 8 and no more tha 20 characters, must include upper case, numeric and non-alphanumeric. Took me so long to generate an acceptable combination that the sign-on code expired!!! Ultimately had to uninstall and reinstall (hours!!).
