SMTP "999" errors with Panasonic network camera
I have a Panasonic BL-C20A wireless network camera running through a
cheap (yet apparently fine) Airlink AR325W router. An Airlink AIC250W wireless network camera is also in my home network. This is a Fry's brand sold under other names like TrendNet. Both cameras work well but the Panasonic has mysterious email-sending problems. For half a day it sent emails fine via motion sensor and timer but suddenly it kept giving errors, which the Panasonic logs shows as "Division 7" "Code 999" (SMTP protocol). Wireless signal strength is usually listed as 22%+ ("normal") per the BL- C20A's status page. Both cameras rarely lose the signal. I don't think the default SMPT port (25) is the problem because the Airlink camera never had email issues, even though the ISP blocks port 25 for spammers. I don't fully understand how that might relate. What alternate ports are there? IP addresses for both cameras are static, UPnP and DHCP are disabled and port forwarding works fine with Panasonic's www.viewnetcam.com. I am able to access that site for both cameras by appending the port # to the URL. I have verified that both cameras match the router's settings (to the best of my ability). SMTP authentication username/password was never needed for the Airlink camera but for a few hours I thought it was the key to the Panasonic's email problems. I now think it was just coincidence and the ISP ignores authentication. No reason one camera would need it and not the other. Have other owners of Panasonic network cameras experienced email glitches and found a cure? Should I look at the router before blaming the camera, even though a much cheaper camera sends email fine through it? Error code "999" seems to be an unexplained generic hangup. In general, what is the most common email problem with network cameras? Thanks for any help. Jack |

I doubt you will find out what it means. I really think the problem is interference or loss of signal on the wireless connection. For testing, move the camera close enough to the router to connect via ethernet cable, and leave it for a few days. I predict the problem will go away. You might also try pinging the camera from the PC, but ping packets are very short, and might have fewer problems. The ISP doesn't know if your mail is coming from the PC or the camera, or which camera. So if authentication is not used on one, it needn't be used on any other. If it were required by your ISP, I predict you would have grave difficulties with the cameras at all times. Daniel Feenberg feenberg isat nber dotte org |
