hardwire lowlight cams.

[j]

i have two lowlight cams that are hardwire.
these are the ones that have a phone wire
coming from them. then plugs into an rca
adapter type
i would like to know if it is possible if i
could view both on the one tv. as i have
them both hooked up to two tv's now.
a friend of mine told me it can be done with
an rca y type splitter. then i can use the
remote from the other cams i use and then
change the channels.is this right
