Description

The present invention is a cloud adapter and surveillance system that allows video recorders for multiple surveillance cameras from different manufacturers to be used as a cloud service.

In recent years, the number of systems that can be used as cloud services has been increasing in various fields, and systems that can be used as cloud services have become widespread in the field of surveillance cameras as well.

Currently, the surveillance camera system that can be used as a general cloud service has a restriction that it cannot be used unless you use a dedicated camera specified by the company providing the cloud service, and the surveillance camera that can use the cloud service is called an IP camera. IP cameras are limited to certain types and use products that have built-in software that can use cloud services.
On the other hand, among all surveillance cameras, the penetration rate of IP cameras remains at about 1/4 of the total in the Japanese market, and about 3/4 of the market uses surveillance cameras that are not compatible with cloud services. There are some issues that need to be addressed.
There are great benefits to being able to use it as a cloud service, and if there is a way to use surveillance cameras and surveillance camera systems that are not compatible with cloud services, there would be great benefits.

FIG. 3 is a diagram for explaining an example of a conventional surveillance camera system that cannot be used as a cloud service.
As shown in FIG. 3, in this surveillance camera system, analog cameras 11_1 to 11_4 are connected to a video recorder 12 using coaxial cables. Switch the display screen using button 121

On the display 13, it is possible to select one of the analog cameras 11_1 to 11_4 as surveillance cameras to be displayed, or to display all four cameras on a split screen.
It is also possible to rewind and play back the video recorded by the surveillance camera on the video recorder.
Further, when submitting the recorded video to the police etc., a person in charge needs to go to the site and copy the recorded video to a medium such as the USB memory 14. This operation of copying to external media increases the risk of personal information leakage.
Further, with the same configuration, it is also possible to configure an IP camera instead of an analog camera, or a configuration in which an analog camera and an IP camera are installed together.

IP cameras are also called digital cameras, and have become popular due to their superior image quality compared to cameras that are used by about 3/4 of the time on the market. However, because the connection distance between the camera and video recorder is short, There is a problem in that the overall cost of the system and the cost of installation work are high because layout design and construction of relay devices and the like are required. On the other hand, for analog camera products, the analog HD standard was devised in recent years and the resolution has increased dramatically, so there is a market trend of using high-resolution analog cameras without changing to IP cameras.

Incidentally, in order to change an analog camera to an IP camera, it is necessary to reinstall the cable connecting the camera and video recorder from a coaxial cable to a LAN cable, which poses the problem of increased construction costs.
An advantage of using it as a cloud service is that it can be used from a remote location.
Having a system that can be used from a remote location has the advantage of being able to manage multiple locations from one location.
