A new approach to IP surveillance – IP cameras, DINA NVR and DINA RMC remote monitoring centre 

Most IP camera surveillance systems today are based on central recording and monitoring of images from remote IP cameras.  This is a good solution for small systems, but in case of larger number of cameras, it requires an enormous bandwidth in the central station.  Also, the management of the system becomes difficult, as all images are stored centrally in a huge database.

The DINA Video Management System from Mirasys Ltd. is based on local recording with DINA NVRs (Network Video Recorders), and central management with the DINA RMC Remote Monitoring Centre.

The images and audio clips from IP cameras are transmitted over a large-bandwidth LAN network to a local DINA NVR, where they are stored.  The advanced motion detection and alarm event management of DINA NVR’s enable further transmission of alarms (including real-time video) to the central station.

Hybrid DVR’s, that support IP and analogue cameras simultaneously, are also available. 

DINA RMC can manage up to 100 remote NVR’s or 1600 IP cameras, allowing real-time monitoring, retrieval of stored video and audio, advanced alarm management and user profile management.  The RMC system consists of a server with SQL database and up to eight workstations.

The main advantages of the DINA IP system are:

• Only relevant images / audio streams are transmitted
• Lower bandwidth requirement at central station
• Less transmissions in public networks - less security problems
• Larger number of cameras can be managed centrally
• Scalable system management at both ends
• Efficient SQL database for alarm event management
• Local and system watchdogs available
• On-site watermarking of images – high data integrity
• Lower risks due to distributed storage and intelligence
