DVR adopt MPEG4/H.264 compression format. Because its own dynamic rang is too large,we have to estimate the size of the recording file each channel per hour according to the code stream to calculate the HDD capacity. Go to main menu->Info->BPS.

Recording time (hour) = Total capacity(M)/ The size of the recording file(M/hour)×channels

ARSP is similar like DDNS, but use the DNS server of the DVR manufacturer

  1. do the network setup and port mapping. You can see the details in the file “Quick setups of DVR remote monitoring”.
  2. Go to “ main menu”-> “system”-> “network service”-> “ARSP”, then type a self-defined user name and click “ ok” to apply for. If the application is failed, there will be a note of operation failure; if succeed, it will return to the “network service” interface. For example, the user name is 123, then the domain of DVR is 123.edvrddns.com. Just type http://123.edvrddns.com in the address bar while visiting by IE. If the HTTP port is not 80, the http port should be added, like http://123.edvrddns.com:81.
