Description

Data verification system, data converter device and method
The data security market is scattered into many data registration device suppliers that all have their own standardizations, especially concerning data signal protocols, meaning 5 that no data verification system is available which can receive data signals from all those different type of devices. Alarming operators have many different applications for receiving data signals of various kinds of (digital) data recorders, cameras and streamers, which is cost inefficient, difficult and susceptible for user errors. A further disadvantage is that the quality of images and functionality supported by the different 10 systems can differ. For example one system can deliver very good image quality at a small network bandwidth while another system only delivers a small amount of frames per second under the same conditions. Every supplier uses a different way of encoding, transporting and decoding of images.
15 Supported functionalities at the verification systems side is limited to the data registration devices capabilities. This often means that for the remote alarm operator important features and functionalities, such as IP alarming, bi-directional audio, trigger information, camera moving, remote switching of e.g. equipment, doors (access control), and snapshots for most protocols are not supported in these type of solutions.
20
These functionalities are generally developed and delivered by the supplier of the data registration device and all have a different (graphical) user interface. For an operator however, it is difficult when there is no standardized way of operating different data registration devices.
25
Suppliers of data verification systems have tried to overcome the problem by implementing the protocols used by different data registration device suppliers into their applications. Although this initially solves the problem of various user interfaces, new problems with compatibility and stability between suppliers of different products and 30 even of the same suppliers are introduced with this solution. Another disadvantage is that a bottleneck in data quality and control possibilities may in some cases be formed by the DVR (Digital Video Recorder) at the client side.
2
In cases where client/server architecture is used, data protocols have been implemented directly at the clients of the data verification system. This may solve the problem of various user interfaces, but it is disadvantageous with regard to fixing bugs in existing protocols, ensuring protocol compatibility, adding protocols of new versions of existing 5 and already implemented products or adding complete new protocols.
Another known approach of implementing the protocols is to implement them into the server application rather than into the individual data verification clients, and let the data verification server convert the data to an internal format before sending the 10 information to the clients. This approach reduces the time and effort required for implementing a new or updating an existing protocol, because only the server needs to be updated and not all clients.
However, problems with incompatible data protocols remain. Although an update has 15 been limited to only one system instead of many, the problem of for example differences in bandwidth and a limitation of supported features remain in this type of solution.
Furthermore, a general concern with the implementation of various data protocols is 20 security of the network both on the data verification systems as on the data registration devices side. With the implementation of protocols of suppliers which can be seen as alien, the need of managing the network security increases dramatically. All protocols must be screened on possible malicious nature and need to be checked on strange network behavior by the provider of the data verification system. With the increase of 25 the number of alien data protocols this becomes more difficult, more time consuming and more susceptible to errors.
It is a purpose of the present invention to provide a data verification system that is able to connect to a plurality of digital data recorders, cameras and other data systems, but 30 with a constant quality of data/images and without the compatibility and stability and security problems.
The invention thereto proposes a data verification system, comprising at least one data verification device, such as a monitor in combination with a personal computer, 3 arranged at an observation location, such as a security center, and configured for displaying at least one data signal, according to at least one data signal protocol, at least a first data registration device, such as a camera, arranged at a first remote (data registration device) location, configured for generating a first data signal according to a 5 first data signal protocol, a data network, such as an IP network, configured to deliver data signals from the at least first remote location to the observation location and at least a first data converter device, located at the first remote location, configured to convert the first data signal according to the first data protocol to the at least one data protocol and to send the converted signal through the data network to data verification device.
10
By providing at the remote location, a data converter system (consisting of at least one data converter device and a data transport device), that converts the data signal generated by the first data registration device, to at least one data protocol the data verification device is configured to receive and display, no conversion is required at the 15 observation location, such as the security center. This provides several advantages, that evidently come to their right merely in cases where one data verification device is used to monitor data signals coming from a plurality of data registration devices. In practice, one or more data verification devices are for instance installed at a security centre, for monitoring a plurality of remote locations, such as public areas, offices, or private 20 houses for example. Each of these locations can have one or more data registration devices, from which data is to be displayed at the security center. Adding a new data registration device to the system does no longer require any updates or modifications to the data verification devices , which is an advantage, since this location usually requires a nonstop use. Furthermore, the system and method according to the present invention 25 may be implemented as an update to existing systems, causing no disinvestments in existing security systems.
The data converter system, that may also be referred to as a multiprotocol receiver (data convertor device) and Protocol convertor (data transport device), may be embodied as a 30 (boxed) device connected to a data registration device that should be connected to the data verification device. A data registration device and a data converter device can be connected by some kind of data connection (like IP, Rs232, Rs485, Composite, etc) for mutual data communication. The data converter device may be coupled to the data 4 network by means of a suitable interface, which may for example be formed by a Protocol Convertor.
The Multiprotocol Receiver (MpR) then is able to retrieve the Data from the Data 5 registration device and then standardizes it to a generic format before transmitting it to the Protocol convertor also located at the data registration devices side. The Protocol Convertor (PC) then is able to send the Data in high quality to the data verification system through a network connection for example with or without a standardized bandwidth in which the protocol ensures a optimal quality of data for verification. The 10 Protocol Converter is described into more detail in the international patent application WO 081 36674, which is hereby incorporated by reference. The use of this multiprotocol converter assures standardized data (for example audio- and video) from the various remote locations, and it assures a galvanic separation between the local data network at the remote location and a observation locations data network.
15
In another embodiment, the data verification system comprises at least a second data registration device, arranged at a second remote location, configured for generating a second data signal according to a second data signal protocol; and a second data converter device, located at the second remote location, configured to convert the 20 second data signal according to the second data protocol to the at least one data protocol and to send the converted signal from the second remote location to the data verification device.
Herewith, a second data registration device can be added, also at a second remote 25 location, without requiring a modification to the data verification device or at the observation location. What goes for a second location here, goes as well for any further location with a data registration device providing a data signal according to a different protocol.
30 When a specific remote location comprises more than one data registration device that all provide data signals according to the same protocol, they can be connected to the same data converter device, up to a number that may be only be limited by the possibilities of the data converter device, for example its number of free connectors or slots. If the data registration device is coupled to the data converter device by means of 5 a local network, the number of data registration devices is in fact unlimited, and limitations are solely caused by the limitations of the network.
However, the data verification system according to the invention may also comprise at 5 least a third data registration device, arranged at the first remote location, configured for generating a third data signal according to a third data signal protocol, wherein the first data converter device is further configured to convert the third data signal according to the third data protocol to the at least one data protocol.
10 In other words, any data converter device in the data verification system according to the invention may be configured to convert a variety of data protocols to the at least one protocol of the data verification device. That means that at one remote location, in principle only one data converter device is required, and once a remote location is installed and configured, more data registration devices can be added.
15
Preferably, the data converter device is configured to convert first, second and/or third data signals with different properties. It can then send the data signal to the observation location, where an operator can decide in real time what signal he wants to retrieve, or, if there are more data registration devices, a plurality of signals can be watched at the 20 same time.
In a further advantageous embodiment, the data converter system is further configured for supporting at least one of the functionalities of IP alarming, bi-directional audio, trigger information, camera moving, remote switching of e.g. equipment and doors 25 (access control), snapshots or other additional functionalities. That gives the opportunity to actively control the data registration device, or to control the remote location.
The invention will now be elucidated with reference to the following figures. Herein: 30 - Figure 1 shows a first data verification system according to the present invention;
Figure 2 shows a second data verification system according to the present invention; 6
Figure 3 shows a third data verification system according to the present invention; and
Figure 4 shows a fourth data verification system according to the present invention.
5
Figure 1 shows a first data verification system 10 according to the present invention where there is only one protocol 12 implemented by the data converter device 11 (also referred to as ‘Multi Protocol Receiver’ device MpR) namely the Bosch Protocol for communication with the Bosch VI equipment 13. The data converter device 11 is 10 coupled with data registration devices 13 via a local data connection 17, and a PC
(Protocol Convertor) 16 is coupled to the data converter device 11 to send data signal according via the data network 15 to the at least one protocol accepted by the data verification system 18 at the observation location 14.
15 Figure 2 shows a second data verification system 20 where the MpR 21 is also able to support more than one protocol. It supports data protocols 22, 22a, 22b which offers the advantage that the risk of having incompatibility between a subset of data protocols at a remote side is much smaller than having to be compatible with a superset of data protocols at the data verification systems side. Furthermore it is possible to solve even 20 the risk of having two devices at one site that are incompatible by adding another MpR for the protocols which are incompatible with each other.
Figure 3 shows a third data verification system 30 according to the present invention where there are respectively Bosch VI and Bosch V2 devices 31 and 32 connected to 25 separate protocol converters 33, 34, wherein the protocol converter 33 is further configured to be compatible with Sony device 35. Bosch VI device 31 is normally incompatible with Bosch V2 device 32. In this manner it is possible to solve incompatibility issues easily and swiftly. When a new Data protocol is added but not needed for every side it is possible to only update the sites that have the newly 30 supported data registration device and leaving all other sites unattended.
Figure 4 shows a fourth system 40 according to the invention, where there are two remote locations each with different data registration devices 41, respectively 42. The data registration device 41 is coupled with a data converter device 44 that sends the data 7 signal via a PC 46 to the observation location 47 with data verification device 48, and data registration device 42 is coupled to the data converter 43 that sends the data signal via a PC 45 to an observation location 47. Both make use of the same data network 49, which may be the internet 49.

Enabling operators to use more functionality of the devices they connect to, and adding more by using the implemented features already available on the PC itself, the system according to the invention is able to supply more features to the operator than the Data registration Device would be able to if it were not combined with a PC. This in fact in 10 practice is a vital feature for operators assist them with relevant generated information and or data . With the present invention all systems automatically can have features like, IP alarming, bi-directional audio, trigger information, camera moving, remote switching of e.g. equipment and doors (access control), snapshot capabilities whether or not it is actually implemented by the data registration device itself. The solution has this all 15 onboard and available for the operator to use if needed.
Security is less complex with the described approach. Only one or a distinct selection of controlled protocols is/are supported between the data verification device and the data convertor system and this will be less likely to be updated than the individual protocols 20 of the different data registration devices as a whole. Next to that it is essential to notice the PC and MpR are connected by a connection as described in the above mentioned international patent application WO 081 36674, making hacking of individual sites nor the data verification device possible.
25 The present so called Multi Protocol Data invention has major advantages against the existing approach of conventional suppliers. Difference in compression methods between different data protocols can be eliminated. Second, no compatibility problems at the data verification devices side. Only one or a selected range of controlled data protocols is/are supported and new protocols are installed/implemented on at the Data 30 Protocol Convertor Systems side. Third, advanced features, like IP alarming, bidirection audio, snapshots always available whether the connected data registration device has these features itself or not. Fourth, controlled, managed stability of the observation location because the risk of incompatible or instable protocols at the observation location is completely reduced to only one or a selected group of controlled 8 protocol(s) instead of many. Fifth, patented connection preventing security problems on the data registration systems side.
