I need to get two cameras wired up to be monitored remotely

I need to get two cameras wired up to be monitored remotely

Postby orangefurball » 2015-Jan-Thu-21-Jan

Hello!

I have been tasked by someone to create some sort of two camera system that can be accessed wirelessly. It also needs to be extremely cheap, there will be thousands per order (they go in conjunction with a companies product) so they can't have interference or anything like that.

The requirements:
Cheap
Camera must be really really small, it can't get in the way
And the final requirement is that it would have to withstand temperatures up to 200C

My original thought was to do a Raspberry Pi with a couple camera modules, but the price and limited availability made that idea go away quickly. I then looked into Arduino based setups, but they can't use two cameras due to the low power processor.

Does anyone have any ideas? I've been struggling for weeks with this and you makers know a lot. I only need to make the idea and one prototype, that's it. I won't be producing the items, just helping out a friend!

Thanks!

Matt

Look at something like that, its relativly low resolution, about 300k pixels (vga 640x400) , uses i2c protocol to talk to the host so you can have multiple cameras connected. If you hook up a pi and two of these and a bit of code it should work.

You did not say if you need both cameras active at the same time.

The $9 is retail one off, if you go straight to the manufacturer you should be able to cut that considerably. The Pi has a load of i2c host support.

I should have been more specific, they are for maintenance purposes (not sure how much detail I can go into) and must be used at the same time.

That would be perfect if I could use two at once, but their operational temperature is 70C max, the size is perfect though.

I'm starting to think that this is impossible!

I would suggest pushing an mail off to those guys, they will probaly either have what you want, or know where to get it.

That temperature requirement is a real killer. Most consumer electronics is only rated to 85C or so; military gear goes up to 125C. Beyond that, it's in the realm of extreme specialization.

But exactly what do you mean "withstand"? I have a friend who puts consumer-grade electronic parts into specialized equipment that get exposed briefly to very high temperatures... but the case surrounding the electronics absorbs enough heat so that the stuff inside doesn't get fried. Also, the stuff is not required to WORK at high temperatures, just to survive the exposure and return to working condition when temperatures get more normal again.

Can you use a fiber-optic bundle to pick up the image at the hot location and convey it to a cooler place where you can scan it?
