Lucille may be short in length but she's long on 'tude
Today Lucille got her rear camera for backing up / checking the dinghy /or security purposes. I had a DLink 5020L PTZ "Cloud Camera" laying around and a Netgear Wifi Router both of which I wired straight into ignition power. I mounted the camera in the rear driver side window. The router I mounted up front.
Then I fired accy mode and waited for both to configure themselves. I fired DLinks app on my phone after hooking up to Lucille_Net wifi - searched for local cameras and voila! The default view will be looking down and behind the bus but since the cam is ptz it can swivel itself around and look at the bus interior when necessary.
No matter where you go .... there you are!
