Hi,
i'm going to buy this ip cam
http://www.dlink.com/uk/en/business-solutions/ip-surveillance/onvif/dcs-2210-full-hd-poe-day-night-camera

it has and External Device Interface (1 DI / 1 DO)

Do you think it is possible to use it with Arduino ?
I'd' like to use GSM shield in such a way that i'll have a phone call when the ip cam detects a motion.

thanks in advance for your help!

Did you read all the documents ?

The DI and DO pins might only be controlled by the software on the PC.
If the camera itself can set DO output for a certain condition, that might be a nice extra.

With the GSM shield you can let the Arduino sms or make a call for any input signals. The camera output of course, but also extra PIR sensors, or radar detectors, or switches, noise level, vibrations, and so on.

In page 48 and page 58 of this document

there are more details..can you help me? How can i understand if the camera can set DO output?

The DI seems to have an internal pulldown, and I don't know the value.
But a protection resistors of 150 ohm should be okay. The Arduino output to 150 ohm resistor, and from the resistor to DI and connect the grounds.

The DO is an open-drain output. You can set the Arduino input as INPUT_PULLUP or add a 4k7 pullup resistor yourself.

But if the camera is able as standalone device to set DO when an event occurs ? I'm still not sure about that. When I read the text it seems possible.
