I thought some of you might be interested in how I use an outdated laptop and smartphone to communicate with my M2, even when I'm away from home. I've searched the forums and I do not see this discussed so wanted to share.
Older laptops and Skype - I prepared an older laptop that had a built in camera with Skype which I have set to auto answer. (Do adjust settings so that Skype only auto answers from "known" contacts - I've been shocked by the number of messages my bird receives from strangers saying "you sound interesting - do you want to chat?") I have Skype on both my laptop and my Smartphone, so I'm able to call at any time and carry on a two way conversation. She can see and hear me, and I can see and hear her.
Older Smartphones and Presence - Presence is a free app that you can download from the Apple app store (not sure if its available yet for Android). It allows you to turn an unused iPhone or iTouch into a one or two way security cameras with sound and video. Set up Presence on both your bird's phone and your phone. On the bird's phone, launch Presence and make that phone the remote camera. You can then use your phone to call. You can just watch and listen, or you can activate your camera and have a two way call.
There's also a number of devices intended as baby monitoring devices that should work.
My bird really enjoys these calls from me and I'm happy to see all is well. Any others call home to talk to their cockatoo? Please share your tips!
