Problems solved by technology

[0003] In the existing video surveillance technology, the power box, network cable or pigtail of the front-end camera are laid from the camera end to the equipment end of the equipment room, which not only increases the length of cable laying, but also makes it difficult to connect all The cables are centrally placed in place. When the cameras are installed densely, the cables in the equipment room may be cluttered and deformed, and in severe cases, they may even be scrapped.

Embodiment 1

[0055] Example 1: If the actual cable entry space in the equipment room is narrow, it cannot be guaranteed that all camera cables are uniformly inserted into the equipment room. When using the video surveillance front-end integrated power supply and network box, the camera cables are connected to the box at the front end (12.1, In 12.2), the camera is connected to the network.

Embodiment 2

[0056] Embodiment 2: as figure 2 ,3 As shown, the video surveillance front-end integrated power supply and network box structure are described.

[0057] There are 48 single P+N air switches installed on the inner panel (11.2) of the box (12.1), which can provide 48 24V / AC power supplies for the camera equipment at the same time; Ethernet is installed on the inner panel (11.3) of the box (12.2) Industrial switches (9.1, 9.2, 9.3) can provide 48 Ethernet ports and power supply ports for cameras at the same time, or provide up to 48 optical ports and electrical ports for access to cameras.

Embodiment 3

[0058] Embodiment 3: as figure 2 , 3 As shown, maintenance and use are explained.

[0059] Each camera can have a fixed power switch and electrical port or optical port access plan, and can clearly distinguish the operation of each camera. If the camera is offline, it can be integrated with a power supply and network box at the front end of the video surveillance The problems are detected and dealt with in a timely manner, which greatly improves the maintenance efficiency.

Abstract

The invention discloses a front-end test box of a video monitoring device, which comprises a power box and a network box;t the power box and the network box respectively comprise a box body, and a panel is arranged on the box body of the power box structure; an alternating-current transformer is mounted on the panel; the panel is provided with a contactor, a double-P air switch, a single-P air switch, a V direct-current transformer, an OBO lightning protection module, a single P + N air switch and a ground wire bar. A box body of the network box is provided with a panel, and the panel is provided with an industrial Ethernet switch and an optical cable terminal box. In order to overcome the defect that the space environment of the existing equipment room cannot meet the cable laying requirement of the camera, the invention provides a mode of indirect access at the front end to ensure that all cameras can be smoothly accessed into the equipment room, so that the cable cannot be seriouslyextruded and deformed, and the utilization rate of the equipment cable is improved.

Description

technical field [0001] The invention relates to the field of video monitoring equipment, in particular to a front-end test box of a video monitoring device. Background technique [0002] The video surveillance front-end integrated power supply and network box structure provide front-end power supply and network equipment integration structure in places where various cameras are densely installed. It is installed in subway station halls, platforms, entrances and exits, and areas where cameras are densely installed, such as video key monitoring of electrified railways. Improve the utilization rate of cables and avoid the complicated accumulation of cables in the equipment room, which belongs to the field of camera equipment installation and debugging. [0003] In the existing video surveillance technology, the power box, network cable or pigtail of the front-end camera are laid from the camera end to the equipment end of the equipment room, which not only increases the length...
