PIMA (Phone, Internet, Mobile, Analog) Server The PIMA server makes many kinds of devices connected together and makes them be able to communicate each other. In virtue of the PIMA server, digital convergence is realized. The PIMA server consists of many servers such as 1. a management server, 2. an IP server, 3. an alarm server, 4. a mobile server, 5. a relay server, and 6. a contents server. Hardware & Software of PIMA Server - CPU : 2GHz Dual CPU - Memory : 1GB - HDD : 120GB - OS : Linux - DBMS : MySQL - Web Server : Apaches - Program : C, C++, HTML, HDML, JAVA, etc. Performance of PIMA Server Generally speaking, the above PIMA server can support more than 100,000 network devices such as network cameras, network A/V servers, network DVRs, home servers, etc. But, the performance of the PIMA server depends on the performance of the hardware platform of the PIMA server. Operators of PIMA Server The PIMA server will be operated by following companies to expand their own business. - Camera manufacturer - Monitor manufacturer - DVR manufacturer - Home network company - Security service company - Internet service provider (ISP) - Mobile phone service Operator |
The management server manages the users and network devices. That is to support registration, update, removal of users, network cameras, network A/V servers, network DVRs, NVRs, access control systems, home servers, etc. IP Server The IP server manages the IP addresses and related information of network cameras, network A/V servers, network DVRs, NVRs, access control systems, home servers, etc. for users with PC, PDA, mobile phones to easily access to them. To support global, private, static, dynamic IP addresses and DDNS (Dynamic Domain Name Server) for easy access by the name. Alarm Server The alarm server sends a notice (e-mail, SMS message, etc.) to the registered user and to record event related information (video, time, etc.) when events occur. Mobile Server The mobile server supports the video/image viewing and camera/relay control from mobile devices (PDA, mobile phones, etc.) Relay Server The relay server broadcasts real time video/audio from network cameras, network A/V servers, network DVRs, NVRs, access control systems, home servers, etc. to users (PC, PDA, mobile phones, TVs, network A/V clients, network monitors, etc.). The relay server is used 1. to increase the concurrent users of a network device or 2. to reduce the internet bandwidth required to stream a video/audio data from one server to multiple clients (for example, PCs, network A/V clients, network video recorders, licence plate recognition systems) in the same LAN. Contents Server The contents server (photo & movie server) displays photos and/or movies on the remote network photo & movie album. |

Why PIMA Server ? The relay server (a subset of the PIMA server) has been installed in the illegal parking prevention system to reduce the network traffic and the cost of the leased internet line between the PTZ camera on the road and the central monitoring center. In this application, reeceiving only one video stream from the PTZ camera on the road, the relay server transmits the received video stream to many clients such as network A/V clients, PCs, license number plate recognition system, etc. With the relay server, there is only one video stream from the PTZ camera on the road to the relay server in the central monitoring center. The relay server distributes the video from the PTZ camera to network A/V client, operator PC, license plate recognition system, high capacity NVR, etc.  The relay server has been installed at a apartment complex to increase the number of concurrent users of the network A/V servers. In this application, several hundreds of concurrent users using home servers at homes, access and see the live video from the relay server which receives the live video from the cameras installed in the parking lots and in the children's playgrounds.  Where installed ? - Apartment complex at Geojedo constructed by Shinwoo - Apartment complex at Namyangju constructed by Dongbu - Apartment complex at Daegu constructed by Taewang - Apartment complex at Pohang constructed by Taewang - Apartment complex at Pohang constructed by Daekyo - Apartment complex at Sangindong, Daegu constructed by Shinil - Apartment complex at Shinseodong, Daegu constructed by Shinil - Apartment complex at Jecheon constructed by Saerom - Apartment complex at Incheon constructed by Shinil - Apartment complex at Chucheon constructed by Daewoo - Apartment complex at Gunsan constructed by Saehan - Apartment complex at Sangam constructed by Daewoo - Gangnam district office for illegal parking prevention system    |
Without the relay server, there are four video streams from the PTZ camera on the road to four clients (Operator PC, NVR, network video clients and license number plate recognition system) in the central monitoring center. This means that the central monitoring center should lease more broad internet line with much higher cost.  |
