IP-based SIP camera phone with automatic water-receiving

The present invention relates to an IP (IP) -based SIP (SIP) camera phone capable of automatic water-receiving.

More specifically, if the IP-based SIP camera phone detects an intruder's motion detection, heat detection, or door opening and closing, it automatically sends a preset mobile number to the remote number and transmits the surveillance video. The present invention relates to an IP-based SIP camera phone capable of autonomous reception with the addition of a phone function capable of automatically receiving a remote control signal including voice and voice.

Recently, many consumers have learned about DVR technology and have learned that DVR has contributed to the digital evolution of CCTV systems. These DVRs can be divided into two eras, the first of which was around 1996, when the functions of the DVR began to digitize. This has saved consumers the trouble of replacing tapes anymore, enabling continuous storage and also making it easy to retrieve the stored data. Nevertheless, the DVR still had to connect the analog coaxial cable (coaxial cable from the CCTV camera to the DVR and from the DVR to the monitor).

The second era is the era of using a PC to view the images stored on the DVR. In this era, coaxial cable was used from the camera to the DVR, and network (LAN cable) was used from the DVR to the PC monitor. In recent years, DVRs have gradually introduced products with a network interface, and expensive products that can be monitored with a general PC using software at a remote site have emerged. (These DVRs are called network DVRs. Although there are advantages, it still uses coaxial cable to connect camera and DVR, and such coaxial cable installation requires expensive installation cost).

As mentioned above, the final step in the digitization of CCTVs is the connection from the camera to the DVR (the connection from the camera to the DVR still uses coaxial cable, which is an analog system), and this part of the CCTV system is analog. It was the last part of the technology that couldn't be done digitally.

An effective and efficient alternative to the above-mentioned problems has emerged. It is called IP Surveillance or Network Camera, which transmits video using IP. The IP camera is a camera used by connecting to a wired or wireless Internet. The analog signal received from the camera module is converted to digital through a decoder and is transmitted through a compression chip. Can be checked on mobile and used as a tool for user generated content (UCC) and home networks.

In other words, as described above, the DVR is a mixture of analog and digital, and the process of converting digital to analog and converting analog to digital has a problem of degrading performance and increasing costs. This connection was solved by connecting the connection to the recorder using LAN, Internet or wireless LAN, not coaxial cable, and digital image and network revolutionized the system's functionality and cost efficiency.

On the other hand, SIP (Session Initiation Protocol) is a recently developed protocol for VoIP. Session Initiation Protocol (SIP) is an application that specifies the procedures for intelligent terminals that want to communicate on the Internet, such as telephones, Internet conferences, and instant messengers, to identify and locate each other, and to create, delete, or change multimedia communication sessions between them. As a signaling protocol of the layer, it is a request / response structure that controls the creation, modification, and termination of multimedia service sessions such as Internet-based conferencing, telephone, voice mail, event notification, instant messaging, and can be used for both TCP and UDP. By using a SIP URL similar to an e-mail address to distinguish it, the service is provided without being dependent on the IP address.

In other words, it is text-based, developed using many parts of HTTP and SMTP as it is, and is easy to implement, and has the flexibility and scalability to create various services in combination with many other protocols used on the Internet. It can be easily implemented even in an embedded system without memory, and it is easy to implement things such as a videophone because of its high scalability.
