12.	Up to 16 Network Cameras or analogue cameras connected to encoder shall be viewable simultaneously by multiscreen view on the browser. It is possible to prevent illegal access such as port scanning, etc. by changing the HTTP port number. Up to 14 users can access to the encoder simultaneously on Unicast mode.

13.	The encoder shall have the capability of User ID and Password protecting all menu settings. The user access level is selectable from three access levels :
Level 1: Setting, Control and View
Level 2: Control and View
Level 3: View only

14.	The Max bit rate per client for H.264 and MPEG-4 shall be selectable from 64/128/256/512/768/1024/1536/2048/4096 kbps and combined with Total bit rate control (64/128/256/512/1024/2048/4096/8192 kbps or Unlimited), or frame priority mode (1 / 3.1 / 4.2 / 6.25 / 8.3 /12.5 / 20fps / 25 fps) is also selectable.

15.	The encoder shall be capable of being configured to automatically transmit alarm images transfer via FTP file transfer and/or e-mail.  In addition the encoder shall support the scheduled transfer of image data via FTP to an FTP server. When the FTP periodic transmission is failed, backup on an optional SD memory card is available.

16.	The encoder shall be able to support uni-cast and multi-cast transmitting.

17.	The encoder shall support IPV4 and IPV6 network addressing.

IPv4:TCP/IP, UDP/IP, HTTP, RTSP, RTP, RTP/RTCP, FTP, SMTP, DHCP, DNS, DDNS, NTP and SNMP.
IPv6: TCP/IP, UDP/IP, HTTP, RTP, FTP, SMTP, DNS, NTP, and SNMP.

18.	H.264/MPEG-4 images can be transmitted over HTTP protocol.

19.	The IP address of the encoder can be detected by software tool.

20.	The encoder shall have Video Motion Detection function with 4 programmable detection areas, 15 steps sensitivity level and 10 steps detection size.

21.	Terminal input, VMD, and alarm command can trigger actions such as SD memory recording, FTP image transfer, E-mail notification, Indication on browser, Alarm terminal output, and alarm command output. JPEG image compression ratio can be changed by alarm so that higher quality image can be provided.

22.	With uploading extension software and optional Registration Key, the encoder shall support optionally Face detection function.

23.	The encoder shall have three external I/O Terminals which can support Alarm input or Alarm output, AUX output. AUX output can be activated by web browser.

24.	The encoder shall have full duplex two-way audio feature and be capable of transmitting and receiving the audio stream through the same Ethernet connection as the video. The audio shall be encoded using the G.726 or equivalent ADPCM standard.

25.	The encoder shall provide an SD Memory Card (SDHC) slot which can support a maximum of a 32Gbytes SDHC Memory card that can cache images (JPEG) in the event of a network failure.  The encoder shall also support manual recording (H.264 / JPEG) and alarm recording (H.264:Pre, Post / JPEG:Post) to the optional SD Memory Card. The encoder shall provide notification of the remaining capacity of the SD memory card.

26.	Alarm log, Manual REC log, FTP error log saved in the SD memory card is displayed on the browser GUI and can be downloaded to the client PC. Playback or Image data download through the log is also available.

27.	The encoder shall be capable of being configured the settings relating to schedules of alarm permission, VMD permission and access permission.
