Caller identification devices

spaceage security systems

These devices are used on the normal telephone line to identify from where the telephone call was made. In case there is threatening call or a obscene call then using such a device it can be seen from where the call originated. Most of the enforcement agencies today are equipped with such devices. Such devices are not expensive. It may be noted that for such a device to be useful this facility must be available in the local exchange. It may also be noted that some times this type of devices are unable to display the originating number under certain circumstances.

These days there are plenty of phones available with Caller-Id feature in built, specially in the grey market. Even fax machines are having this feature as a standard.
