Although analog cameras have been miniaturized to the point that true bullet cams are accessible and affordable, our analog cameras' image quality leave a lot to be desired.
When I say "bullet camera," I'm looking for an imaging body about the size of a pen, rather than (for example) a paper towel roll, so if it has a ring if IR illuminators around the lens, it's probably too big.
Google isn't much help, because apparently when you say bullet, advertisers believe a 60mm mortar is more relevant than a 9mm Beretta. The top 3 results for "ip bullet camera" were:
(44mm/1-3/4" dia) DLink DCS-7010L HD Mini Bullet Outdoor Camera, seems like a decent POE cam but too big
(77mm/3" dia) Samsung SNO 6011R, likewise POE IP cam but too big
(unknown diameter) Q-See QCN7001B couldn't find diameter but too big per the images
It takes a fair amount of time to investigate the details, and I quit after the first 3 were not relevant.
In IP cameras, the closest I have seen is the Mobotix M14/M15 and the Axis P12. Mobotix is quite pricy and too big. Axis may be an adequate choice, but is there a larger set of choices? Also, is there anything that meets the traditional bullet form factor, even if it has a nearby remote "server"?
Thanks.
