BACKGROUND OF THE INVENTION
1. Background - Field of the Invention.
This invention relates to the field of vehicular security systems. More specifically, this invention comprises a vehicle surveillance system having data recording and data transferring capabilities.
2. Background - Prior Art.
Vehicular security systems seek to protect the owner of a vehicle from theft or occupants of a vehicle from hijacking. Various security systems and devices are currently used for such purposes, including car alarm systems, "panic" type transmitters, automobile demobilization systems, and GPS tracking systems. Although these systems and devices serve useful purposes, there remains a need for a system that would allow law enforcement to easily determine the identity of a thief or hijacker so that the thief or hijacker may be apprehended.
There is also a need for a system for monitoring "at-risk" individuals when they are driving or riding in a vehicle. For example, many parents desire the ability to monitor their children's driving when the parents are not present in the vehicle. Also, governmental agencies have a need to monitor individuals convicted of certain offenses, particularly when these convicted individuals are driving. In addition, school systems desire the ability to better monitor the conduct of their bus-riding students to prevent bullying and other disruptive behaviors that endanger the safety of the students.
It is therefore desirable to provide a security system for a vehicle which is capable of the previously described monitoring functions. It is also desirable for the security system to be capable of transferring video and/or audio data of activities occurring in the vehicle.
SUMMARY
The present invention is a security system for monitoring activities occurring within a vehicle. The security system includes a video camera and microphone which are positioned to monitor activities occurring within said vehicle. In one embodiment the video camera is attached to the rearview mirror and the microphone is attached to the top liner in the cabin.
A receiver is also provided. The receiver receives video and sound data from the video camera and stores the data in its hard drive. The receiver may be placed in the trunk or another secure location. The receiver includes a recording means configured to record the video data to the hard drive. A data port is provided on the receiver and is electronically connected to the hard drive. The data port may be a USB ("Universal Serial Bus") type data port. An external memory unit, such as a jump drive, is also provided for transferring memory from the hard drive to another location. The receiver includes an external memory unit detecting means configured to detect whenever the external memory unit is connected to the data port. The external memory unit detecting means and the recording means may both be provided as software or firmware in the receiver.
In the preferred embodiment, the receiver also includes a transmitter configured to wirelessly transmit data to a remote location. For example, the transmitter may transmit the data to a receiver on a personal computer.

DETAILED DESCRIPTION
The present invention, a vehicle security system, is illustrated in FIG. 1. Car (10) is equipped with video camera (12) and microphone (14). Video camera (12) is positioned in an orientation to monitor the activities occurring within the cabin of car (10). In the current example, video camera (12) is integrated with the rearview mirror of car (10) such that the lens of video camera (12) faces the occupants of the vehicle. Video camera (12) could also be positioned in a different location in car (10) or multiple video cameras may be used, with each camera having a different viewing angle of car (10). Microphone (14) is attached to the liner material on the top of the cabin so that it may pick up sounds from the front seats and back seats of the car. Microphone (14), like video camera (12), may be placed in other locations as well.
Microphone (14) and video camera (12) are electronically connected to receiver (16). Receiver (16) is placed in a secure location in car (10). In the present example, receiver (16) is placed in the trunk of the vehicle. Receiver (16) records and transmits video and sound data transmitted to receiver (16) from video camera (12) and microphone (14), respectively.
As illustrated in FIG. 2, microphone (14) transmits sound data to receiver (16) where it is compressed by encoder/compressor (20). Video camera (12) transmits video data to receiver (16) where it is encoded by encoder/compressor (20). Encoded and compressed video and sound data is then transmitted to computer (18). Computer (18) includes a hard drive for storing the video and sound data. Computer (18) also includes software of firmware
which directs receiver (18) to perform its various functions and operations. In particular, computer (18) includes a recording means configured to record the video data to the hard drive and an external memory unit detecting means configured to detect whenever an external memory unit is connected to data port (22). Data port (22) is provided on the exterior of receiver (16) and is electronically connected to the hard drive. In the preferred embodiment, data port (22) is a USB ("Universal Serial Bus") type data port. An external memory unit, such as a jump drive is also provided for transferring memory from the hard drive to another location. The external memory unit detecting and recording operations may both be controlled and directed by software or firmware in contained in computer (18).
Receiver (16) also includes transmitter (24) which is configured to wirelessly transmit video and sound feed to a remote location. For example, transmitter (24) may transmit the data to a receiver on a personal computer. Transmitter (24) may transmit "live" video and/or sound feed utilizing various wireless transmission media that are known in the art. In one embodiment, receiver (16) may wirelessly transmit the data via satellite, GPRS (General Packet Radio Service), cellular or radio signals.
FIG. 3 shows a side view of receiver (16). Receiver (16) includes jacks for audio inputs (26) and video input (28). The type of input jacks used will obviously depend upon the type of video camera and microphone that is used. Receiver (16) also includes data port (22) which is configured to receive the external memory unit. Although it is not illustrated, receiver (16) also includes a power supply cord. Receiver (16) may draw power from car (10) or an auxiliary power source.
A series of LED lights are provided on the side of receiver (16) to provide status information to the user. Recording indicator LED (54) is on when receiver (16) is recording video and/or sound data to its hard drive. Memory indicator LED (56) is on when the amount
of data stored in the hard drive is nearing the capacity of the hard drive. Memory indicator LED (56) may be set to turn on at any predefined memory usage threshold, however. Data transfer indicator LED (58) is on when data is being transferred from the hard drive to the external memory unit. Data transfer indicator LED (58) turns off when the transfer is complete.
A schematic illustrating operation of the present invention is provided in FIG. 4. Audio data from microphone (14) is compressed, as indicated by compress step (32). Video data from video camera (12) is encoded concurrently with the compression of audio data, as indicated by encode step (30). A buffer is then written which combines the encoded video and compressed audio, as indicated by write step (34). This "feed" may be transmitted "live" wirelessly as indicated by transmit step (36). Simultaneous to the live transmission, the computer in the receiver determines whether hard drive (52) is full or contains a predefined threshold of video and/or audio data as indicated by determination step (38). Determination step (38) is iteratively performed at predefined time intervals during the recording process. If it is determined that the hard drive is full or contains the predefined threshold quantity of data, a portion of the oldest data is deleted, as indicated by delete step (40). The portion of data that is deleted may correspond to a predefined interval of time. For example, the oldest 30 minutes or hour of data may be deleted when such a determination is made. It should be noted that smaller or larger intervals of time may also be used. If it is determined that the hard drive is not full or does not contain the predefined quantity of data, the data is recorded to hard drive (52) as indicated by record step (42).
The computer in receiver (16) also has a means for detecting whenever the external memory unit is plugged into data port (22), as indicated by detect USB step (48). If an external memory unit is detected, the computer looks to see if the external memory unit has a
security key as indicated by detect key step (46). The security key authenticates that the external memory unit is an authorized device for receiving data from receiver (16). Once the computer validates that an external memory unit is authorized, the computer downloads the data stored in hard drive (52) to the external memory unit as indicated by download step (44). The computer also deletes the data from hard drive (52) during or after transfer of the data to the external memory unit as indicated by delete step (50).
The operations illustrated in FIG. 4 may be directed and controlled by software or firmware in receiver (16). The reader will note that data compression need not involve a separate piece of hardware. The compression and encoding may be controlled by the same software of firmware that controls the other operations of the system. This allows for greater data security and makes the device very easy to use. Unlike conventional surveillance systems which record data to a tape or other removable storage medium, the present invention stores data to a hard drive. Once stored to the hard drive, the data cannot be deleted unless the user has an external memory unit with the appropriate security key. Microphone (14), video camera (12), and receiver (16) are preferably installed in such a manner that the security system cannot easily be detected. This further reduces the risk that a thief, hijacker, or kidnapper would discover the security system. Because the preferred system transmits a live feed wirelessly, a record of the data may also be kept on a remote system. This is particularly useful if the receiver is destroyed or cannot otherwise be recovered.
The preceding description contains significant detail regarding the novel aspects of the present invention. It should not be construed, however, as limiting the scope of the invention but rather as providing illustrations of the preferred embodiments of the invention. As an example, the external memory unit need not be USB compatible. Likewise, data port (22) can be any type of port suitable for transferring data from hard drive (52) to the external
memory unit. Such a variation would not alter the function of the invention. Thus, the scope
of the invention should be fixed by the following claims, rather than by the examples given.
