Abstract: Described is a cellular security system for monitoring an asset from a remote monitoring site without utilizing a signal modulating device or a cellular voice service. The cellular security system includes a detector, a display device, a cellular telephone that includes a camera and email capabilities, and a remote email device. When the detector detects an occurrence, the display device is activated such that the display device indicates the status of the detector. The cellular telephone captures a photo-image of the activated display device and composes an email and attaches the captured photo-image to the email. The cellular telephone sends the email to a remote email device, which is located at the remote monitoring site. From the remote monitoring site, the photo-image is viewed using the remote email device such that the status of the detector of the cellular security system is revealed.
