Camera as a sensor
-
Hi all,
Another question that might have been answered elsewhere but I couldn;t find the answer. There are 3 cameras in the shop but no project that uses them. question is, is it even possible to use a sensor as a security camera? Again, I know next to nothing about realtime programming. can the mysensor protocol support that? nothing fancy like a streaming video - just a photo every now and then triggered by motion sensors
@Moshe-Livne what you want to trigger on mysensors side? motion event or sending picture?
most of IP cameras are able to send pictures by themselves, you do not need mysensors for this
but you can integrate camera with my sensors to trigger motion event like PIR sensor can domotion event is definitely supported by mysensors
you need to look at camera integration possibilities to see how you can integrate
the possible scenarios:- camera is configured to upload pictures to FTP at motion event, do setup of FTP server on RPI or even arduino to initiate mysensors event on any upload. Or you can connect many cameras and can differentiate by their IP
- camera is configured to send email using SMTP - do similar as for FTP
- camera has a special API to report motion events. Integrate it according to API
- camera has a wired output of a motion event. connect regular mysensors sensor to it
sense and drive

@axillent I was asking about the tiny camera modules that appear in the mysensors store. good and reliable IP cameras are not cheap and they are (sometimes) very awkward to set up and integrate with your wifi (and I actually don't like it so much that my WLAN password reside on a device outside my house). My dream sensor would be a cheap motion event with a photo as a doorbell, for example using the VGA camera you would end up (if rpi is not needed) with a 15$ device.. I am million miles from doing anything like that, was hoping that someone else already done that....

@Moshe-Livne IP cameras are starting from $50. they have a processor able to process images at a good speed for you to trigger a motion event in a second after real motion starts. Using camera module you will have to do the same - processing images one by one to detect changes and this will trigger event. You will need at least a RAM to store a series of images at your camera resolution. RPI should be sufficient for this, but the cost of RPI + wifi + camear module + power supply is becoming higher comparing to IP camera.
regarding security. many modern routers allows to setup isolated WIFI spot with separate password

this one could be sufficient indoor http://foscam.us/products/foscam-fi8918w-white-wireless-ip-camera-21.html
and this outdoor http://foscam.us/outdoor-cameras/fi9803p-plug-play-1-0-megapixel-1280x720p-h-264-outdoor-wireless-ip-camera.html -

@axillent i was thinking using PIR for detecting motion, snapping a shot and sending it. you are right about the ram - i would need sd card reader probably

PIR? it is something different. You need a clear view on what you want. From you first post I realized that you want to detect motion by analyzing camera output etc by analyzing images. Using PIR is very different

@axillent no, no.... as I said, i want to use it as cheap entrance device. PIR is good enough to trigger the response

there are many foscam clones shipping free from China starting at $50
@axillent I have one of these, skyeyes. It is not foscam replica, just looks like it. has no snapshot url so completely useless. annoying....

can you explain exactly what do you want?
PIR is triggering event and someone is taking picture at this moment?sense and drive

OK, I see. Do you want both PIR and camera module been connected to the same device? If yes this could have not much todo with mysensors. It can be regular arduino or rpi sketch sending pictures by FTP or email.
If you want to have PIR on other device you can use mysensor to sens PIR and trigger other device to take pictures using mysensors radio -
I have one (soon two) RPi with camera modules that take pictures and store / send to Pushbullet when a certain MySensors PIR is triggered. Has worked pretty well for the past year. and a Pi + Camera is still reasonably cheap plus it's a "real" computer so it can do anything with the camera and images. And the Pi camera is still pretty good, unless you happen to get a real bad clone from Ebay or something. Hardly worth it. I don't know how good these cameras in the store are, but I doubt they come anywhere near the simplicity and guaranteed quality of the Pi camera module.
If you like, you can also use the "motion" package on the Pi, but that will be a real hassle with false triggers and all. The cheap PIR motion sensors have worked surprisingly well. It's more a question of positioning them right so you don't have problems with sunlight, fireworks, curious magpies etc.
I have my RPi inside camera housings I got from AliExpress. There are a couple there that are pretty good. I think finding a bracket can be more of a challenge. I have J-brackets that fit under the eaves.
I have the raspimjpeg script running on the Pi btw. You could just use raspistill I suppose but it's nice to be able to manually view the camera feed from the browser and have remote control at your fingertips. Hell, you could even get one of those motorized RPi things that are able to turn the camera.
I have a sort of Power Over Ethernet going for my cameras btw.

@bjornhallberg That is a very cool setup although i suspect its not very economical. the pi+camera would cost ~80$ i think. plus casing and bracket would get you very close to foscam if not higher. I was aiming at cheapest possible solution. maybe even one that can run on battery.

I have never seen devices like the ones you mention. they could be a good solution

do not stick to it's original application
the idea is that open-wrt can run on this small things. Open-wrt is a linux type system, you can program it very similar to RPI
it is very cool if any camera working example exists for open-wrt -
