older cctv cameras (Hanwell W13)

Hi guys, I was just coming to ask if anybody has older security cameras? I have a small monitor and want a live feed of my garden to watch birds and animals! Im looking for an older one because the ones I have currently dont work with my tv sadly, if you want I can give the camera i have in exchange for an older cctv camera if that's okay? I know those older cameras are quite common in corner shops and stuff, Maybe someone here is willing to upgrade their cameras?
