Greetings,
I am new to this group so my apologies if this request has ever arisen before.
A relative wants to install a camera in the bell chamber (where the bells are) of a church and feed the output down to the ringing chamber (where the people and visitors are) about 60ft below. There is considerable danger in the bell chamber when the bells are swinging and that is without the sound levels so it has to be remote.
I thought about using a wireless camera to a router below to feed a PC, but that gives rise to security issues. There is need to switch any lighting from the ringing chamber (there is power in the bell chamber) to be sure that the bell chamber lighting has been switched off after use (cost of electricity plus fire risk) so it would be easy to run a CAT5/6 at the same time.
I then had the bright idea of using a rPi at the bottom to connect to the camera cable, and a HDMI feed into a cheap TV which can then be stored in a (relatively) thin and locked wall cupboard.
My request for help - does anyone know of readily available software that would run on the rPi and present the remote pictures? Ideally it should be power-up bootable so that keyboard and mouse are not required for normal use. I have a rPi - I have had for nearly two years - but I have yet to power it up due to other domestic pressures (getting used to retirement/daughter's wedding/becoming grandparents) but I am hoping to get that resolved after our hols.
Any (polite) advice gratefully accepted.
