Product Description

There is no requirement of Static IP, Dynamic IP, No need of port forwarding, No high technical settings & support required. Specifications JVS-D***0 are a series of high cost-performance video and audio standalone DVRs, including 4 channels, 8 channels and *6 channels. JVS-D***0 uses H.**4 compression standard and embedded Linux O/S, and keeps Capturing and Compression Video and Audio, Network Transmission, Remote Management, PTZ Control, Motion Detection, Alarm Management and Mobile Viewing functions. JVS-D***0 includes all functions of DVR (Digital Video Recorder) and DVS (Digital Video Server). JVS-D***0 uses CloudSEE technology for network transmission. No need to apply for dynamic domain and set the port mapped of router. The biggest advantages are easy operation, high connection rate and good transmission effect. Jovision pays attention to stability and hommization while designing JVS-D***0 series standalone DVR. JVS-D***0 supports multi-level thunder-proof protection, Data self-repairing, Update online, Set Automatically, Search host-end automatically. There is no requirement of Static IP, Dynamic IP, No need of port forwarding, No high technical settings & support required. The advantage of AnTone/CloudSEE technology compared with DDNS DDNS Principle and Operations: Normally once users restart network device (like modem), the new IP will be different from the former IP. DDNS resolves the problem of dynamic IP due to using PPPoE. Now, client-end software may find and link host-end software by using DDNS technology. In fact, when client-end software want to link with host-end software, the servers of DVR cards suppliers use the DDNS technology to search the current IP of host-end pc and then send it to client-end software. In this way, client-end software can get the correct IP and use this IP to receive video images from host-end software directly. However, DDNS technology needs to set Dst. port in the router. This is the biggest disadvantage. Users need to set a series complex parameters. And once there is something wrong in the router and need to be reset, all parameters need to reset. The most importantly, most end-users can not deal with it by themselves. They need the help of professional workers. Connection Effect: When client-end software want to link with host-end software, the DDNS technology search the current IP of host-end pc and then send it to client-end software. In this way, client-end software can get the correct IP and use this IP to receive video images from host-end software directly.Briefly, server help client-end software to get the IP of host-end pc and client-end software receives the video images from host-end pc directly (P2P). The effect of network connection depends on network quality between host-end pc and client-end pc. If the distance is small, connection could not be affected. But if the distance is long, connection could be affected and the video signal could be reduced during transmission. AnTone Principle and Operations: AnTone uses UDP (User Datagram Protocol) to skip router and does not need to set Dst. Port. AnTone server gives every host-end pc an AnTone code. When client-end software want to link with host-end pc, client-end software just use only the AnTone code of host-end pc. In fact, the AnTone code is a identification code of host-end pc. When client-end software apply to receive video images, server searches the current IP of host-end pc and then send it to client-end software. In this way, client-end software can get the correct IP and use this IP to receive video images from host-end software directly (P2P). Briefly, AnTone technology does not let end-users or installing workers set Dst. Port of router. AnTone is easy to operate for end-users or installing workers. In addition, if client-end software can not receive the video images from host-end pc, AnTone server will receive the video images and then send them to client-end software (TURN). It means there is one more method for network connection compared with DDNS. Connection Effect: If network environment is the same, the connection effect of DDNS is the same as that of AnTone. Briefly, server help client-end software to get the IP of host-end pc and client-end software receives the video images from host-end pc directly. The effect of network connection depends on network quality between host-end pc and client-end pc. If the distance is small, connection could not be affected. But if the distance is long, connection could be affected and the video signal could be reduced during transmission. CloudSEE Principle and Operations: Based on AnTone technology, CloudSEE uses UDP (User Datagram Protocol) to skip router and does not need to set Dst. Port. There are also two modes for network connection, such as P2P and TURN. Compared with AnTone, the advantage of CloudSEE is that CloudSEE also uses CDN (Content Delivery Network) technology. The details of CDN is according to http://en.wikipedia.org/wiki/Content_delivery_network . Connection Effect: Briefly, there are a group of servers in a region, all over China currently and all over the world in the future. If the distance between client-end software and host-end pc is small, the network connection between them depends on P2P or TURN of one server. But if the distance between client-end software and host-end pc is long, the network connection between them will depend on P2P or TURN of two servers.
