Modular system for video data transmission.

The invention relates to a modular system for standard and/or special video cameras for data transmission of video images.

Video cameras are used in large numbers and in a variety of designs to monitor people and/or buildings, and to monitor industrial production processes for quality control purposes. The following technologies are currently used to transmit video data: cable (analog RG59, RG 58 etc., digital LAN CAT 5/7 etc.), radio, fiber optic cable. In many applications where video data is transmitted via cable from the camera, it is advantageous if the power supply and, if necessary, control signals are also transmitted via the video cable, so that cable can be saved. Only a small selection of cameras that contain suitable electronics can be used here, so that power can be transmitted to the camera and the video image can be transmitted from the camera to the monitor, recorder, etc. When transmitting via radio, separate radio transmitters must be connected via cable unless the transmitter is integrated into the camera. The same applies to video data transmission via fiber optic cable.

Especially when using mobile video surveillance systems such as those used by the police, LKA, BKA or Federal Border Guard, different video transmissions from the respective camera are required, since wired or wireless transmission is not always possible.

Currently, customers buy many cameras with different transmission options in order to solve all data transmissions on site. In order to make the necessary video surveillance as cost-effective as possible and to use each camera with different transmission options, a modular system is required that is compatible with the cameras used. Such a system is not available on the market.

The object of the invention is to create a modular system which enables the user to very quickly convert one and the same camera from wired data transmission without power supply (standard camera) to wired data transmission with power supply via video cable or to radio data transmission or to data transmission via fiber optic cable. In particular, the system should be applicable to standard cameras available on the market.

The object is achieved by a modular video data transmission system (1) designed according to claim 1.

Because the modular system can be equipped with compatible plug connections to standard cameras (11), one and the same camera can be converted into a radio camera, fiber optic camera or wired camera with power supply via the video cable by simply replugging the respective transmission module.

The connectors on the back of the module(s) for additional cable connections and/or power supplies can be varied so that compatibility with standard power supply systems (wall-mounted power supplies, batteries, etc.) can be ensured without making any changes to the camera.

In an advantageous further development of the system, two or more data transmission systems can be accommodated in one module (1), which then saves even more space, especially in mobile video surveillance systems.

The module (1) can therefore be manufactured in variants:

a) Integration of radio technology (3) and voltage regulator (2) to upgrade the camera to a radio camera. The connectors (4) and (5) are the camera's mating connectors. The camera (usually 12V) and the radio transmitter are supplied with power via the connector (6) and the voltage regulator (2). When integrating a 12V radio system, the voltage regulator can be omitted

b) Integration of a transceiver module (7) which transmits the video signal from the camera via connector (4) to the video cable (RG58/59 etc.) connected via connector (6) and decouples the power supply available via the video cable from the video signal via connector (6) and transmits it via connector (4) as a "standard video signal" to the camera (11)

c) Combination of a) and b) in one module (1).

d) Integration of a fiber optic coupler which modulates the video signal of the camera into a fiber optic signal via connector (4). The power supply for the fiber optic module is ensured via connector (10). The power supply is also given to the camera via connector (5).

Preferably, the module (1) is plugged in to enable a quick change in data transmission. For longer-term use, the module (1) can also be screwed to the camera to achieve a higher mechanical hold.

1. Modular system ( 1 ) for a video camera ( 11 ), preferably used mobile, for easy conversion of the data transmission from the camera, data transmission specified by the customer such as wired video transmission, to other transmission methods with corresponding additional benefits.
