hello i have two hikvision DVR's on two different locations and both are online. am able to view one location using EZVIZ my question is will i be able to view the other location via EZVIZ since these two locations are using different subnets??
Yes, provided they're both connected to EZVIZ, you should be able to view them just fine, either on the same EZVIZ account or a different account for each site - subnet does not matter.
