Are your camera's images not being received by Sensr.net? It may be a DNS issue preventing your camera from being able to reach our servers (ex: f3.sensr.net), as it is unable to find the IP address for the FTP server.
The easiest fix is to set a DNS server in your camera's network settings page. Rather than digging out the DNS settings specific to your ISP, we recommend simply using 188.8.131.52 and 184.108.40.206. These are DNS servers from OpenDNS, another great startup.
If your IP camera is working in a live view through your router, and Sensr.net is still not receiving any images, please e-mail firstname.lastname@example.org, and we will get back to you as soon as possible.
