Configuration Setting: - Page 106 - Video Resolution / Video Mode / Bit Rate / Frame Rate / Video Quality Scene without moving object Video Resolution / Video Mode / Bit Rate / Frame Rate / Video Quality Scene without moving object ..CIF / VBR / 256 k / 30fps / 4 Running bitrate 214 k/ 28 fps ..CIF / VBR / 256 k / 30fps / 31 Running bit rate 138k / 28 fps The blocked image will be observed on the image. - Page 107 - Scene with moving object ..CIF / CBR / 256 k / 30fps / 4 Running bit rate 284k / 8fps The actual running frame rate is lower than 30 fps due to the constraint of available network bandwidth. ..CIF / CBR / 256 k / 30fps / 31 - Page 108 - Running bit rate 260 k / 16 fps The video quality is lower and thus the network bandwidth requirement is less. The side effect of this is the poor video quality (mosaic effect on moving object) ..CIF / VBR / 256 k / 30fps / 4 Running bit rate 926 k / 28 fps The VBR setting ensures a better video quality and thus over bandwidth traffic is the result. - Page 109 - ..QCIF / CBR / 256 K / 30fps / 4 ..QCIF / CBR / 256 K / 30fps / 4 Running bit rate 231 k / 23 fps The viewable region is less than CIF and network usage is also less. ..QCIF / CBR / 256 K / 30fps / 31 Running bit rate 54 k / 28 fps - Page 110 - ..QCIF / VBR / 256 K / 30fps / 4 ..QCIF / VBR / 256 K / 30fps / 4 Running bit rate 50 k / 28 fps The actual network bandwidth usage is less due to QCIF resolution. ..QCIF / VBR / 256 K / 30fps / 31 Running bit rate 59 k / 28 fps - Page 111 - The poor video quality setting make the text a little fuzzy. Bandwidth Usage Category : IPCAM / Connection / General Question: What’s the network bandwidth requirement of each IPCAM connection? How can I estimate or configure the video parameters to get a better video quality and performance ? Answer: If you have an ADSL network connection to surf the internet, please ensure your available bandwidth before configure you surveillance camera video quality parameters. The bit rate configuration in surveillance camera shows how much network bandwidth is reserved for each client connection. For example, your ADSL network bandwidth is 512K/1M. The surveillance camera is installed in your home. That means your upstream bandwidth is 512kbps for your surveillance camera. Ensure your surveillance camera video mode is CBR so that you can better - Page 112 - estimate the network usage. The surveillance camera will not run over your ADSL bandwidth capacity. If your video mode configuration is VBR, the surveillance camera may pump out more than what your ADSL line can afford. The packet loss will occur and poor video quality will be observed in Windows client side. Case 1 : surveillance camera video parameter setting: i) CIF / CBR / bit rate 256 k ii) 3 active client connections on the go bottom line video bandwidth usage will be 256 k * 3 = 768 k If G.711 audio codec is also enabled for each connection, an extra 64k for each connection shall be included in final bandwidth usage. (Video 256k + audio 64k) * 3 = 960 k Surveillance Camera - Page 113 - Dynamic Domain Name Service Category : IPCAM / Configuration / General Question: How can I find out IPCAM IP address if I my IPCAM connect to Internet via PPPoE mode? Answer: Please subscribe an account from and use the DDNS client service in NSC3615 . You shall be able to use the registered domain name to visit your NSC3615. Configure the DDNS setting from webpage “Network” ..”DDNS” DDNS Client Enable : Enable or disable the usage of DDNS client function. If this function is enabled, users can access the device by FQDN specified by the registered DDNS Alias bellows. DDNS Alias : the dynamic domain name used for your registration from DDNS Username : Account username subscribed from registered DDNS alias name DDNS Password : Account password subscribed from registered DDNS alias name - Page 114 - - Page 115 - Factory Default Setting Category : / IPCAM / Installation / NSC3615 Question: What's the factory default setting of NSC3615? How can I reset NSC3615 to factory default ? A Answer: • NSC3615 Factory Defaut Setting: Fixed IP mode : IP address : 192.168.0.100 Subnet mask : 255.255.255.0 Default admin account : Username : admin Password : admin • Roll back to Factory Default By Webpage : Use IE and login to IPCam server. Follow the instructions shown below: Webpage : System..Others..Reset Data to Factory Default By Hardware push button : Push the button underneath(marked “Restore Default”) the pinhole at the bottom of NSC3615 case. - Page 116 - Version Information Category : IPCAM / Installation / General Question: How can I find out NSC3615 firmware version information and ethernet MAC address? Answer: 1) log on to web server 2) Refer to left-hand side of main webpage as shown belows - Page 117 - Video Decoder Plug-in ActiveX Control Download Category : IPCAM / Operation / General Question: How do I know the video NSC3615 video decoder is not installed in my local P...
