Description:
FIELD OF THE INVENTION 
       [0001]    The instant invention relates to a receiving unit for a surveillance arrangement. 
       BACKGROUND OF THE INVENTION 
       [0002]    Prior Art 
         [0003]    As a consequence of the increase of criminal actions, surveillance systems are widely used for controlling determined zones. This is the case of enclosed neighborhoods or country clubs. Also, public buildings have surveillance and safety personnel. This has been extended to apartment buildings. 
         [0004]    Personnel devoted to this task come from safety organizations and agencies created to this end. 
         [0005]    Also, there are places controlled remotely using different technological resources, such as fixed or mobile cameras, movement sensors, microphones, different recording means, etc. 
         [0006]    It is clear that all applications used imply a data accumulation to be identified, checked, administered and directed to give a response to the call or signal emitted from a determined event. 
         [0007]    Information captured by different means is sent to a remote place where signals from different locations being surveyed are checked. In this remote place the material received is studied and, if necessary, the proper response is established. 
         [0008]    Alarm buttons are also known. These are push buttons activating an alarm or signal allowing intervention of specialized personnel. 
         [0009]    Known systems have some disadvantages overcome by the instant invention. 
         [0010]    For example, alarm buttons of prior art operate 1 to 1, i.e., each bottom uses a link independent from the others, this requiring complex equipment which is avoided by the use of the invention. 
         [0011]    Besides, generally, all radiofrequency receiving equipment have a limit of 99 positions; therefore, if clients to be surveyed are more than a hundred, multiple receptors are required, which in turn need to be different from each other, which results in a greater complexity for administering data received from the different points. 
         [0012]    The instant invention may administer an unlimited number of codes and identify which is the activated control; therefore there is no limit in the amount of controls for a determined location. 
       SUMMARY OF THE INVENTION 
       [0013]    Basically, the instant invention relates to a receiving unit for a surveillance arrangement comprising a container including a radiofrequency receiver, a processor, a nonvolatile memory, a relay, a removable SD memory, a network module and an audio module. 
         [0014]    The receiver is engaged to a network connection and, by means of this network, to a database having access from any virtual point or from a control center. 
         [0015]    A preferred embodiment of the invention will be now described in connection with the accompanying drawings. Components of the invention may be selected among various equivalents without departing from the scope.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0033]    The receiving unit for a surveillance arrangement disclosed herein is highly suitable for identifying a signal among all possible signals received from a determined location. 
         [0034]    In fact, by the use of the invention, it is possible to identify that the signal has been triggered, for example, by a person in an apartment of a building. Such identification may provide additional information decisive in some cases, since such information may be comprised by codes, photographs and names and telephones of the persons associated to the alarm emitter. If the person involved has any health problem or any other problem preventing himself/herself any action, information includes associates codes and names and telephone numbers or persons or institutions to be contacted. 
         [0035]    In what concerns to a neighborhood, it is possible to use, apart from the personal device for emitting the alarm signal, a radiofrequency emitter (with the same operating principle of remote controls) which is activated when a normal open contact is closed or when receiving information engaging it to the alarm of each of the houses in that neighborhood. 
         [0036]    In case of using a single receiving unit, if one of the alarms is activated, the event will be reflected immediately at the monitoring interphase which, among other data, will show a location map of the house, photographs, names and telephone numbers of associated persons. 
         [0037]    The advantage, as compared with present monitored alarms using a cell network connection per each house is that, apart from adding monitoring of persons by means of remote controls, the arrangement of the invention only needs one network connection per neighborhood, regardless the amount of houses to be monitored, which drastically reduces network connection costs and complexity of installations as well as maintenance costs. In case distances so require, known radiofrequency repeaters should be installed. 
         [0038]    The receiving unit for a surveillance arrangement of the invention -a- includes a radiofrequency receiver - 1 - for detecting an electromagnetic wave of a determined frequency emitted by a remote control - 10 - activated by the user under a determined condition. 
         [0039]    The signal is sent to a processor - 4 -, is decoded, and then may have access to a non-volatile memory - 2 - to verify whether the code received is an active code, i.e. authorized by the service supplier, also verifying whether the receiving unit -a- is active, thus completing the process. 
         [0040]    The code list in said non-volatile memory - 2 - is updated periodically according to changes made by the service supplier, such as inclusion of new users or discharge of users due to suspension of services, lack of payment, etc. 
         [0041]    Once the code validity and operation of the receiving unit -a- are checked, processor - 4 - activates an outlet connected to a relay - 5 - operating as a connection to any existing system, opening a normal closed contact or closing a normal open contact thus triggering the signal in the corresponding system. 
         [0042]    Simultaneously, processor - 4 - codes and records the event in the database - 8 -, along with the remote control unique number - 10 - and the unique number of receiving unit -a- by means of the network module - 6 - which may be wired, wireless or GPRS/EG/4G to record the event. 
         [0043]    In locations where there is no network connection or GPRS, or where the network has defects or lack of connection, the receiving unit -a- may send information of the event through text messages (SMS). In these cases, data of remote control - 10 - users may be loaded in the non-volatile memory - 2 - to send complete information of the event in the text message directed to the administrator of such location. 
         [0044]    This configuration may be also effected upon request from the user, for example, if the user has no network connection at all. 
         [0045]    Interphase - 9 - , having access to the database - 8 -, allows operating in real time thus assuring that the events will be seen by the person in charge of the control of the location from which the event comes from, as well as of the receiving unit -a- and remote controls - 10 -, thus allowing amendments as well as suspensions and admissions. 
         [0046]    Each receiving unit -a- allows by means of audio module - 7 - and network module - 6 -, a two way audio communication started remotely from interphase - 9 - as well as reproduction of a pre-recorded audio message which may be sent and updated at the time of unloading updating of unique codes of remote controls ( 10 ) as well as updating of the state of receiving units -a-. 
         [0047]    In case a register is to be created, all events may be saved in a removable SD memory - 3 -. 
         [0048]    In order to avoid copy of the elements as well as preventing hacking, once the mentioned components are introduced in the receiving unit -a-, the radiofrequency receiver - 1 -, processor - 4 -, memory - 2 -, the network module - 6 -, relay - 6 -, audio module - 7 - and removable SD memory - 3 -, a resinous substance is injected sealing the arrangement. When this substance is dry, it is practically impossible to have access to the components. 
         [0049]    Database - 8 - contains information related to remote controls - 10 - distributed among the service users, such as the steps to follow in case of alarm, these guidelines being previously agreed upon by the user and the service supplier. 
         [0050]    Information stored in database - 8 - also includes allocation of identification codes to each of remote controls - 10 - and identification codes of remote controls of associated clients, location of the place where the service is rendered, including an interactive map of the zone, and data of persons to whom each code is related. Said database - 8 - may be housed in a web server to which access is possible by means of interphase - 9 - 
         [0051]    The supplier as well as the user may have access to removable SD memory - 3 -; from there being able to set the connection interval to unload the updated status and the list of unique codes of remote controls - 10 - as well as the period of time during which the pushbutton should be pressed in order that the event be effective, thus avoiding accidents due to mishandling, which could result in false positive events. 
         [0052]    Audio messages previously saved in removable SD memory may be executed or not, as well as the minimum waiting time between unique codes of remote controls - 10 - thus avoiding multiple records for the same event. 
         [0053]    Configuration data may be also entered to have access to the network by active module Ethernet, Wifi or GPRS/3G/4G. Also, telephone numbers may be included to send the event via SMS in case network fails. Thus active network module GPRS/EG/4G and telephone numbers are used to send the event via SMS in case this operating mode is selected. In this case, the active module should also be GPRS/3G/4G. 
         [0054]    Remote controls - 10 - based on present technology have a universe of combinations from 2 to 20 which results in 1048576 possible unique codes. 
         [0055]    The radiofrequency receiver - 1 - in not limited in what concerns to its ability to receive codes with a length of more than 20 bits, therefore, it is compatible with remote controls that may carry out said emissions in the future. 
         [0056]    Further, the universe of possible combinations to generate unique codes of each receiving unit -a- is only limited by the size to be given to the information alphanumerical scope used to send said code to the database - 8 -, thus, with a scope of only 5 digits, possible combinations are over 900 million. 
         [0057]    In practice, there are no limitations in what concerns to the amount of surveyed locations or the amount of remote controls - 10 - which may be individualized per each location. 
         [0058]    In an alternative embodiment which may be used separately or as a complement to remote control - 10 - a radiofrequency emitter is used which is activated when a normal open contact is closed or when receiving a supply. 
         [0059]    Said radiofrequency emitter is connected to the alarm of a house and to a receiving unit -a-. If one of the alarms is activated, the event will be immediately reflected in interphase - 9 - which, among other data, will display a map showing the house location, photographs, names and telephone numbers of associated persons, etc. 
         [0060]    The advantage over present monitored alarms, using a connection to the cell network connection per each house or flat is that, on one side, simultaneously, it may add individual monitoring of people and on the other only requires a network connection per neighborhood, regardless the amount of houses to be monitored. 
         [0061]    This drastically reduces costs of network connection as well as complexity of installations and maintenance. It is obvious that in case distances are an issue, it will be necessary to install repeaters. 
         [0062]    It should be understood that the particular embodiments shown and discussed herein are not the only ways in which the invention can exist. They are currently preferred embodiments of the invention. One skilled in the art can readily see other variations that would also fall within the scope of the appended claims.
