Description

Technical Field

[0001] This utility model relates to the field of image acquisition, specifically to a device for realizing HDMI video recording of in-vehicle equipment. Background Technology

[0002] Video surveillance is now widely used, and in-vehicle network video recorders are used to record video of vehicles in motion or parked for extended periods, allowing for reconstruction of events in case of accidents. Currently, in-vehicle network video recorders can only record images from network cameras. However, some in-vehicle devices output high-definition HDMI images, which also need to be recorded simultaneously. This necessitates adding an HDMI recorder. Using two recording devices simultaneously leads to inconsistent event reconstruction times, increases the cost of the recording equipment, and makes equipment maintenance inconvenient. Summary of the Invention

[0003] The technical problem to be solved by this invention is how to record high-definition HDMI video images output by in-vehicle equipment.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a device for realizing HDMI video recording of vehicle-mounted equipment, including a network hard disk recorder and an HDMI network encoder. The HDMI network encoder is connected to a monitoring device with HDMI output via an HDMI cable, and the HDMI network encoder is then connected to the network hard disk recorder via a network cable. The HDMI network encoder is added to the network hard disk recorder by loading an ONVIF camera.

[0005] The HDMI network encoder is configured with the ONVIF communication protocol, and its Ethernet interface is connected to the network hard disk recorder via a network cable.

[0006] The network hard disk recorder can be cascaded to multiple network cameras or HDMI network encoders via a network switch.

[0007] This utility model presents a device for recording HDMI video from vehicle-mounted equipment using the aforementioned technical solution. Without adding an additional HDMI recorder, it converts the HDMI video from the vehicle-mounted equipment into an Ethernet network, treating it as a network camera. This facilitates connection to a network hard disk recorder for storage. The network hard disk recorder can be cascaded to connect multiple network cameras through a network switch. The recording management software is mature and cost-effective. Attached Figure Description
