摘要: The present invention is generally directed to a system and method for monitoring the level of light surrounding an automatic teller machine (ATM). In accordance with one aspect invention, includes plurality sensors disposed in varying locations around ATM. Preferably, some will be near ATM, while others dispersed at various distances order effectively monitor lighting A circuit provided within ATM communication sensors. addition, radio frequency (RF) transmitter configured communicate status remotely located receiver. Finally, receiver interfaced telephone line forming part public switched network (PSTN), wherein receive communicated from RF information remote via PSTN. also conditions machine. steps disposing communicating computer further step network. preferred embodiment, last
