But Nowadays mopre people prefer IP cameras ，because IP cameras have more higher resolution than analog system，and IP system have direct access function by PC and mobile application，So when we want to replace the analog cameras by HD ip cameras ，but we do not want to change the cabling which are done several years ago 。is it possible for us to replace analog cameras by IP cameras but keep same coaxial cable ?
Yes，it is possible !
