A Bluetooth-based cordless mouse apparatus has a communication function of an internet phone and optionally further has a USB mass storage so as to enhance a user's convenience and improve voice quality. This apparatus provides several functions such as a wireless mouse, a wireless keypad, a USB mass storage, a wireless presenter, and a wired/wireless phone through a single Bluetooth protocol based device, and allows letter/number input in presentation. A wired/wireless phone-based terminal in a communication system has a Bluetooth-based wireless camera module and an image transmission function via an internet network or a public network to realize a remote security function. This system allows a user, who is out, to check inner conditions of a home by using a mobile phone or an internet-connected computer, thus realizing home monitoring using an embedded camera module.
