Has anyone built a simple video\sound door intercom ?. I would like to have a transmitting device (I have Fez Spider, Cerberus, FezMini and Cerbuino-Bee) that contains a GHI camera module and microphone, loudspeaker (and some other stuff (RFIDsensor, buttons leds and LCD display). Via (max 8 wires) or wireless i would want to communicate with my receiver (and Main Module) which has mic, speaker and T35 display. From the main module i want to hear a buzzer when remote module (gate) button is pressed. Then camera (and lights) are switched on, and i see the person at the gate om my T35 screen. I can speak to and hear the person at the gate , and if i wish, i can open the gate (i have a 12v latch for the gate that works on a small relay).
I have most of the neccasary techniques going ( opening the gate by rfid tag, Pincode on a keyboard\LCD and remote button ) I only need to get video and sound communication between the gate and my main module. On the video side (one-way) i thought about getting the video-streaming code from http://www.tinyclr.com/codeshare/entry/385 and then send the bitmap to my Main module through uart or i2c , but i dont know if that could be done fast enough. I dont expect really high updating speed on the image, but around 1 or 2 fps would be acceptable.
I do have a GHI music module ( http://www.ghielectronics.com/catalog/product/317 ), but i havent discovered how i could use that for two way sound (intercom) function.
Maybe someone is interested in building this with me just because he\she can…
