Wireless security video system with a pre-alarm buffer
First Claim
1. A security system comprising:
- a plurality of battery operated security video cameras, each having an RF receiver and operating in a standby inactive video mode, providing a low electrical power consumption, or in an active video recording mode that consumes a greater amount of electrical power;
a plurality of security sensors for detecting a security/alarm event, each having an RF transmitter for transmitting an RF security/alarm event message indicating detection of a security/alarm event;
wherein an alarm event detected by a security sensor of the security system causes the security sensor to transmit an RF security/alarm event message which causes the security system video cameras to awaken from the standby inactive video mode into the active video recording mode.

Abstract
Security systems are disclosed in which intrusion security sensors provided on the perimeter of a protected space immediately activate a plurality of wireless RF, battery operated, low current drain security video cameras elsewhere in the protected space to enable pre-alarm video recording by the security video cameras. Each security video cameras is capable of operating in a standby inactive video mode, providing a low electrical power consumption, or in an active video recording mode. Each security sensor includes an RF transmitter for transmitting an RF security/alarm event message indicating detection of a security/alarm event. Upon detection of an alarm event by a security sensor, the security sensor transmits an RF security/alarm event message which causes the security system video cameras to awaken from the standby inactive video mode into the active video recording mode.
