Canyon CNR-WCAM413 is uvc mjpg_stream352x288 on Debian Etch

[xyz]

Hello folks,
My test installation is on Debian Etch (Zoneminder 1.23.3 was installed from a binary .deb package). I tested 7 various USB cameras (if not more) to get some working. E.g. Logitech E3500 cooperated only up to 176x144 level and the actual picture was unavailable even then... Ya'know, Debian is a server not a desktop... with the relevant drivers present

The camera that started to work without hassle, was CNR-WCAM413 . It costs some 225 EEK (15EUR) here in Estonia, in Prisma food shop . The google'able USB string is 0ac8:3340. I opened the corpse to get rid of blue glow. I had to put black hats on two internal LEDs or the blue light somehow found it's way to the sensor. China is China. The sensitivity is usual - no surprises.

(social reality under camera control). Plz do not stare it more frequently than my slow DSL can serve.

Here are the technical snippets:

Here are the mjpg_streamer parameters for two cameras simultaneuosly running in addition to the first one which goes via Terratec TV card. Somewhere in manuals it's said that mjpg_streamer supports max 320x240 resolution, as you see it is not true.

The camera that started to work without hassle, was CNR-WCAM413 . It costs some 225 EEK (15EUR) here in Estonia, in Prisma food shop . The google'able USB string is 0ac8:3340.

The camera has been looking outside for one week. It is behind the 5mm window glass at floor 0, warmly packed into foam plast. Outside temperature is cold in Estonia: last night it was -5 degrees by Celsius.

The results are rather cost-concious. Here are some more snapshots.

Extra Bright snow


40 minutes before sunrise


Normal conditions


Night, car lights


However, once/twice per every morning and once/twice per evening the camera enters the oscillating mode. It seems like the onboard electronics is trying to compensate the white balance and ... it fails (Ya'know - fellows Chinese engineers compensating for Estonian light... ). However, these oscillations will not last long - usually less than a minute.
