Security protection system and method
First Claim
1. A security and detection system, comprising:
- sensor means for sensing an alarm condition and for generating a first signal when an alarm condition is sensed;
manual activation means for generating a second signal upon manual activation by a user;
video and audio recording means responsive to the conditions represented by said first signal and said second signal for recording images and accompanying sound information, and for generating corresponding video and audio signals;
memory converter means for converting said video and audio signals to a format convenient for storage and transmission;
memory means for storing said converted signals; and
transmission means for transmitting said converted signals to a base unit at a remote location.

Abstract
A security protection system comprises sensors to detect an alarm condition and a controller that controls the operation of a still-video and audio recording unit. When the sensors activate the controller, the controller turns on appropriate lights and activates the recording unit, and the visual and audio signals from the recording unit are converted to digital and stored on a magnetic disk. The converted signals are also transmitted through a modem to a base location for contemporaneous monitoring of the events which triggered the sensor. The controller can also be activated manually, and may be reset in case of a false alarm. The base location is able to activate the controller for verification or retransmission of the signals.

29. A method of recording, storing, and observing at a remote location events relating to an alarm condition, comprising the steps of:
-
sensing a first alarm condition; recording the events in still-video format and accompanying audio, and producing corresponding electrical video and audio signals; converting the video and audio signals to digital signals; storing the digital signals; placing the memory location addresses of the stored information in a memory address register; transmitting the digital signals to a base location; and updating the memory address register to start position in preparation of receipt of further signals relating to a second alarm condition, while retaining the memory location addresses of the stored information for backup purposes. - View Dependent Claims (30, 31, 32)

33. A method of observing, recording, and transmitting information concerning events, comprising the steps of:
-
manually activating a still-video camera; recording by means of the camera the events in still-video format and accompanying audio, and producing corresponding electrical video and audio signals; converting the video and audio signals to digital signals; storing the digital signals; placing the memory location addresses of the stored information in a memory address register; transmitting the digital signals to a base location; and updating the memory address register to start position in preparation of receipt of further signals pursuant to another cycle of operation, while retaining the memory location addresses of the stored information for backup purposes.
