    I bought this unit model #21012 several years ago and was very happy with the ease of setup. I did however have to contact support for help in remote access. Your rep was very helpful. Recently my provider, Century Link changed my router and I lost the remote ip address. After contacting Michel, he was very helpful and had me up and running in short time. Very pleased with the product and service.
