FIELD OF INVENTION  
         [0001]    The present invention relates generally to surveillance system, and more particularly to remote control video and audio surveillance network system.  
         BACKGROUND OF THE INVENTION  
         [0002]    Surveillance security system has played a very important role in today&#39;s world. Since the attack of the World Trade Center, all civilized societies demand for more and more security control in both government and private sectors. Video and audio surveillance are the most basic and are the biggest demand in the industries. Furthermore, much more sophisticated network systems are also required to satisfy today and future needs.  
           [0003]    Quality video surveillance equipments are also very expensive. The security surveillance industries need a line of low cost but high quality video equipment such that the users can have more choices.  
           [0004]    Thus there is a need for a complete line of low cost surveillance video and audio system with a lot of choices to satisfy every user&#39;s requirement. These equipments must be easy to be integrated into both basic and sophisticated surveillance systems. In addition there is an urgent need of video/audio surveillance network such that this network system is low cost, massive, easy to access, easy to control, fast in communication, global and secure from theft and hackers.  
           [0005]    All the video, audio and control signals are bundled together and transmitted through data channels and lines. This is much more cost effective than coaxial video and audio cables in most of the surveillance systems.  
           [0006]    Furthermore, most remote surveillance systems are static. Users can only watch picture data submitted by the video capturing stations and cannot demand for continuous changing of view or focus and receive the image feedback instantly. This invention provides the dynamic instant control capability and responses to the users.  
           [0007]    The present invention provides such a dynamic video/audio global surveillance network system.

VBCS  10  can also be connected to other node systems (NS) via the connecting system  28  or to the Internet via the connecting system  29 .  
         [0065]    [0065]FIG. 5 is showing a local area video surveillance network system (LAVSN)  2  with NS  6  and NS  7  linked together by connecting system  28 . FIG. 5 also represents a basic dynamic video on demand teleconferencing system. NS  6  comprises of the same setup and components as in FIG. 4 except without the VS  100  system. User  131  is controlling the VBCS  10  and is in front of VS  17 . Remote video site  133  comprises of VS  16 , IR signals bundler, receiver &amp; transmitter  12  and IR signals converter, receiver &amp; transmitter  11  is connecting to VBCS  10  via the cable  19 .  
         [0066]    NS  7  comprises of the same setup and components as NS 6  (in FIG. 5) without the remote video site  133 . User  130  is controlling the VBCS  140  and is in front of VS  128 .  
         [0067]    In practice, initial conditions require both VBCS  10  and VBCS  140  have software  15  installed and activated; user  131  uses VBCS  10  to send request to VBCS  140  to establish the proper handshake between the two VBCS  10  and  140 . After the software  15  handshake is completed at both VBCS  10  and  140 , both user  131  and user  130  can control both VS  128  and VS  17 . As a result, both users can demand and retrieve the particular video images, focusing, magnification (zoom quality) etc. from VS  128  and VS 17 . They can also hear each other via the built in microphones of the video cameras  94  from the speakers  142  of the VBCS  10  and  140  respectively. Thus, this system represents a dynamic video on demand teleconferencing system. Two user video base computer stations (VBCS  10  and VBCS  140 ) are shown in the drawing; in practice, it is users&#39; choice to determine the number of user video base computer stations to be in the teleconferencing system. The software  15  also provides the users a choice to set an user authority list with pre-defined seniority table for the users so that there will be no conflicts when two or more users try to control the same VS at the same time.  
         [0068]    As the remote video site  133  is connected to VBCS  10 , both users  131  and  130  can access the control of VS  16  of remote video site  133 . VS  16  is a surveillance camera system installed at a specific location. As a result, both users  131  and  130  can watch the video and audio data captured by VS  16  instantly and remotely control all the functions of the video camera  94  of the VS  16  and the image capturing direction as well. Thus, this present invention represents the dynamic video on demand surveillance system with multiple users. In practice, it is users&#39; choice to determine the quantity of remote video site  133  to be in the system and the authorization of access right to users.  
         [0069]    [0069]FIG. 6 shows the universal dynamic video on demand surveillance system including the universal dynamic video on demand teleconferencing system. The NS  6  of LAVSN  2  comprises of the same setup and components as NS  6  shown in FIG. 5 and is connected to Internet  5  via the connecting system  29 . The NS  9  of LAVSN  3  comprises of the same setup and components as NS  7  shown in FIG. 5 and is connected to Internet  5  via the connecting system  29 . Both Web computer  73  and server  66  are connected to Internet  5  via connecting systems  29 .  
         [0070]    In operation, initial conditions require all involved systems in the community network, which is defined as all the equipments in the surveillance system shown in FIG. 6, have the software  15  installed and activated. VBCS  10  connects to the VBCS  46  address through the Internet  5  and initiates the software handshaking processes between the software  15  of both systems. This handshake also includes authorization verification by both VBCS systems. Upon the completion of handshaking processes, user  44  at VBCS  10  and user  41  at VBCS  46  will communicate the way same as user  130  and user  131  of FIG. 5. As user  45  initiates the connection to VBCS  10  with Web computer (WC)  73 , the software  15  of both systems will go through the same software handshaking processes with WC  73 . Upon the completion of handshaking processes user  45  will join in and communicate with user  44  and user  41  through their VBCS and Web computer systems. Furthermore, they also can remotely control all the VS in the overall system (community network). Thus, this system represents the universal dynamic video on demand teleconferencing system.  
         [0071]    In practice, an user can communicate to all the VBCS systems as he gets connected with access approval to any one of the VBCS systems which is already in the communication community, which represents the universal dynamic video on demand teleconferencing system. It is users&#39; choice to define the number of users in the overall communication community.  
         [0072]    As the remote video site  133  is connected to VBCS  10 , all users in the communication community can access the control of VS  16  of remote video site  133 . VS  16  is a surveillance camera system installed at a specific location. As a result, all users can watch and listen to the video and audio data captured by VS  16  instantly and remotely control all the functions of the video camera  94  of the VS  16  and the image capturing direction as well. Thus, this present system represents the universal dynamic video on demand surveillance system with multiple users. In practice, it is users&#39; choice to determine the quantity of remote video site  133  to be in the system and the authorization of access right to users.  
         [0073]    The server  66  equipped with server software  23  is connected to the Internet  5  via connecting system  29 . It can serve as the data center such that it can store data when requested by users from any VBCS in the communication community. It can also function as the centralized authorization center for all users to have connection authorization verified before gaining access to the communication community. This provides security to all users from data contamination, hacking and theft. Thus this system represents the universal dynamic video on demand surveillance system with security protection.  
         [0074]    [0074]FIG. 7 is the retrieval process flow chart of direct communication by a Web computer (WC  68 ) system on requesting and retrieving data from VBCS  27  of node station  7 . Video station  128  is the video station of node station  7 . The initial condition requires VBCS  27  has the software  15  up and running and is linked to the Internet  5 ; and the identity and password of the Web computer  68  is already in VBCS  27 &#39;s data record. The Web computer  68  is also required to have the software  15  up and running and is linked to the Internet  5 . Through the Internet connection WC  68  connects to VBCS  27  and sends request for communication to VBCS  27 . VBCS  27  will then check for verification of WC  68 &#39;s identity and password. If failed, request from Web computer  68  will be rejected. Otherwise, VBCS  27  will activate video station  128  after verification and approval of WC  68 &#39;s identity and will wake up VS  128  if it is in sleep mode. Through the Internet  5  connection, VBCS  27  communicates with WC  68  and enables WC  68  to submit controlling input requests for VS  128 ; and VBCS  27  will act accordingly to control the VS  128  as per WC  68 &#39;s request. VBCS  27  will collect the result data, which also includes the video and audio signals from VS  128  and then sends the data back to WC  68  via the Internet  5  connection. Upon receipt of the data, WC  68  will display the video data on the monitor screen. This data display window can also be a multimedia window. WC  68  can also broadcast the audio data through the speakers  142 .  
         [0075]    Web computer  68  can stay on working with VBCS  27  as long as it needs and receives instant responding video and audio data from video station  128 . Web computer  68  will log off from VBCS  27  after completion. Thus, this represents a basic dynamic video on demand surveillance system.  
         [0076]    [0076]FIG. 8 is the dynamic video on demand communication flow chart between two node station (NS) systems within a LAVSN system. FIG. 8 illustrates the process of VBCS  10  of NS  6  initiates the connection to VBCS  27  of NS  7  and then establishes the communication between the two systems. Initial conditions require that the two systems VBCS  10  and VBCS  27  are linked together with connection system  28  and both systems have software  15  running. The overall process is composed of (a) the demand and retrieval process of request made by VBCS  10  and (b) the verification of authorization and supporting process of VBCS  10  in response to request from VBCS  27 .  
         [0077]    The demand and retrieval process of VBCS  10  is similar to the process for Web computer  68  as stated in FIG. 7 description except without connecting to the Internet  5 . Process begins with VBCS  10  sends request for communication to VBCS  27 . VBCS  27  will then check for verification of VBCS  10 &#39;s identity and password. If failed, request from VBCS  10  will be rejected. Otherwise, VBCS  27  will activate video station  128  after verification and approval of VBCS  10 &#39;s identity. If video station  128  is in sleep mode when not being used; VBCS  27  will wake up and activate video station  128 . VBCS  27  communicates with VBCS  10  and enables VBCS  10  to submit controlling input requests for video station  128  and VBCS  27  will act accordingly to control the video station  128  as per VBCS  10 &#39;s request. VBCS  27  will collect the result data, which also includes the video and audio signals from video station  128  and then send the data back to VBCS  10 . Upon receipt of the data, VBCS  10  with the software  15  will display the video data on the monitor screen. This data display window can also be a multimedia window. VBCS  10  can also display the audio data through the speakers  142 . It is VBCS  27 &#39;s user choice to display the data from video station  128  on the multimedia window screen of VBCS  27 .  
         [0078]    VBCS  10  can stay on working with VBCS  27  as long as it needs and receives instant responding video and audio data from video station  128 . VBCS  10  will log off from VBCS  27  after completion.  
         [0079]    The verification of authorization and supporting process of VBCS  10  in response to request from VBCS  27  begins with VBCS  10  receives authorization request from VBCS  27 . VBCS  10  searches through its databases to verify if VBCS  27  is a registered user and if the password is correct. Process will stop if results are negative. Otherwise VBCS  10  will activate video station  16  after verification and approval of VBCS  27 &#39;s identity. If video station  16  is in sleep mode when not being used; VBCS  10  will wake up and activate video station  16 . VBCS  10  communicates with VBCS  27  and enables VBCS  27  to submit controlling input requests for video station  16  and VBCS  10  will act accordingly to control the video station  16  as per VBCS  27 &#39;s request. VBCS  10  will collect the result data, which also includes the video and audio signals from video station  16  and then send the data back to VBCS  27 . Upon receipt of the data, VBCS  27  with the software  15  will display the video data on the monitor screen. This data display window can also be a multimedia window. VBCS  27  can also display the audio data through the speakers  142 . It is VBCS  10 &#39;s user choice to display the data from video station  16  on the multimedia window screen of VBCS  10 .  
         [0080]    VBCS  10  will stay on supporting VBCS  27  as long as it receives request from VBCS  27  and send instant responding video and audio data from video station  16  to VBCS  27  until VBCS  27  logs off from VBCS  10  after completion.  
         [0081]    This represents dual channels dynamic video on demand communication with multimedia window display at the VBCS  10  and  27 . In practice, it is users&#39; choice to determine how many users VBCS systems can join together at the same time and how many multimedia windows to be display at the same time. All the processes of (a) the demand and retrieval process of requesting to VBCS  10  and (b) the verification of authorization and supporting process in response to request from VBCS  10  will be automatically initiated as another VBCS or Web computer connects to VBCS  10 . Upon approval, all the processes of (a) the demand and retrieval process of requesting to other VBCS systems in the community and (b) the verification of authorization and supporting process in response to request from VBCS in the community will be automatically initiated. Since software  15  is installed in all computer systems therefore they are all capable of multimedia functions, the process of new system introduction can run in parallel with other current supporting functions. The new arrival VBCS or Web computer will join, request and retrieve data from the community system upon approval of authorization from all present VBCS in the community system.

Otherwise VBCS  10  will activate video station  16  after verification and approval of VBCS  27 &#39;s identity. If video station  16  is in sleep mode when not being used; VBCS  10  will wake up and activate video station  16 . VBCS  10  communicates with VBCS  27  through the Internet  5  thereafter. It enables VBCS  27  to submit controlling input requests for video station  16  and will act accordingly to control the video station  16  as per VBCS  27 &#39;s request. VBCS  10  will collect the result data, which also includes the video and audio signals from video station  16  and then send the data back to VBCS  27 . Upon receipt of the data, VBCS  27  with the software  15  will display the video data on the monitor screen. This data display window can also be a multimedia window. VBCS  27  can also display the audio data through the speakers  142 . It is VBCS  10 &#39;s user choice to display the data from video station  16  on the multimedia window screen of VBCS  10 .  
         [0086]    VBCS  10  will stay on supporting VBCS  27  as long as it receives request from VBCS  27  and will send instantly responding video and audio data from video station  16  to VBCS  27  until VBCS  27  logs off from VBCS  10  after completion.  
         [0087]    This represents dual channels dynamic video on demand communication with multimedia window display via Internet  5  connection at the VBCS  10  and  27 . In practice, it is users&#39; choice to determine how many user VBCS systems can join together at the same time and how many multimedia windows to be display at the same time. All the processes of (a) the demand and retrieval process of requesting to VBCS  10  and (b) the verification of authorization and supporting process in response to request from VBCS  10  will be automatically initiated as another VBCS or Web computer connects to VBCS  10  via Internet  5 . Upon approval, all the processes of (a) the demand and retrieval process of requesting to other VBCS in the community by the new comer and (b) the verification of authorization and supporting process in response to request from all VBCS systems in the community will be automatically initiated. Since software  15  is installed in all computer systems therefore they are all capable of multimedia functions, the process of new system introduction can run in parallel with other current supporting functions. The new arrival VBCS or Web computer will join, request and retrieve data from the community system upon approval of authorization from all present VBCS systems in the community system.

         [0089]    Video Station (VS)  16  comprises of a video camera  94  installed in a remote-control camera activator system  92  mounted on a remote-control equipment mounting device  96 . Remote-control equipment mounting device  96  can perform vertical tilt motion and horizontal rotational motion as described in prior art disclosed in patent application Ser. No. 10/201,092 (Remote-control utility equipment mounting apparatus). The remote-control activator system  92  is described in prior art disclosed in patent application Ser. No. 10/142,069 (Remote-control device for video camera).  
         [0090]    Process begins at the I/O data connector  13 . As soon as I/O data connector  13  receives input signals for the control of remote-control activator system  92  and the equipment-mounting device  96  from the VBCS  10 , it will pass all the input signals to the IR signals converter, receiver, &amp; transmitter  11 , where all signals will be encoded or encrypted into signals function  38  and emitted out through the built in IR electronic components. IR signals bundler, receiver, &amp; transmitter  12  will detect and receive the signals function  38  and decode it into driver functions to drive the camera remote-control activator system  92  and the remote control equipment mounting device  96  respectively. The feedback signals from camera remote-control activator system  92  and the remote-control equipment-mounting device  96  are sent to the IR signals bundler, receiver, &amp; transmitter  12 . The video and audio signals captured by the video camera  94  are also sent to the IR signals bundler, receiver, &amp; transmitter  12 , where all the signals will be encoded or encrypted together as signal function  38  and then emitted out through the built in IR electronic components. The IR signals converter, receiver, &amp; transmitter  11  will detect and receive the signal function  38 ; and decode it into camera remote-control activator system  92  feedback output signals, equipment-mounting device  96  remote control feedback signals, video data signals and audio data signals functions, and all these signals will be passed to the I/O data connector  13 . Thus, the signals function  38  is the bundled signals, which also includes video and audio signals being transmitted and received between IR signals bundler, receiver, &amp; transmitter  12  and IR signals converter, receiver, &amp; transmitter  11  wirelessly.
