Camera In Production Line Monitoring 30 Milk Bottles Per Minute

In case of camera used for monitoring a production line that produce 30 Milk bottle per minute. Is that mean if we need to count number of bottles we can use camera with 30FPS. Please advise

30 milk bottles per minute or per second? You say per minute but that seems pretty slow. That would only be a milk bottle once every 2 seconds. If it was only a bottle once every 2 seconds, you could do that with a 1fps stream.

Assuming it's 30 milk bottles per second, I have no experience but I suspect you would need more than 30fps as that would be cutting it close if there was any jitter or frame loss. And 60fps cameras are fairly common now.

Yes, It is 30 Bottle per second, you recommend to use more than 30fps. right?

I have no experience monitoring 30 bottles per seconds but if you do 30 frames per second, you will only get 1 frame per bottle. If anything goes wrong (either the line is slower or faster or the camera drops frames or has jitter), the count would likely be off. And since 60fps cameras are common now, that would be safer.

Btw, this typically falls within machine vision cameras / systems that are designed to deal with such applications.

I would recommend the 60fps range and higher. I know for sure that sony has a 60fps PTZ camera, but I wouldn't recommend it for something as simple as counting milk bottles. I'd look into machine vision cameras, like John and the others are suggesting.

Why do you want use a camera?

Why not just use a photoelectric sensor?

Machine vision cameras are capable of several hundred frames per second.

Two Axis models seem to be made for such applications:

Both of the new fixed cameras can provide HDTV 1080p video at frame rates of up to 50/60 fps or HDTV 720p video at frame rates of up to 100/120 fps. This allows for detailed video capture of fast moving objects, which can be of great importance in industrial applications, especially when monitoring a production line. Details of parts and packages can be monitored easily and precisely, enabling full control of the production process.
