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 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.

Oscillating video, 2136064 bytes (A slow server WARNING!)
