NC-11DF is a 1 / 4" 1 Megapixel CMOS sensor IP camera with a built-in web server. It supports 2-way audio and 3D+2D digital noise reduction. The user can view real-time video via IE browser, and the video can be stored in Micro SD card and playback remotely. NC-11DF is HD 720P real time , its IR distance can reach 5meters. Since NC-11DF supports power over ethernet, it could be connected to Netsys' NV-202P, which is a long reach ethernet extender with PoE, as an application.

IP survillance with PoE
Power over Ethernet (PoE) is a technology that integrates power into a standard LAN infrastructure. It enables power to be provided to a network device, such as an IP phone or a network camera, using the same cable as that used for network connection. It eliminates the need for power outlets at the camera locations and enables easier application of uninterruptible power supplies (UPS) to ensure 24 hours a day, 7 days a week operation. NV-202P supports IEEE802.3af / IEEE 802.3at standard.

1. What is NC-11DF related products?


NC-11DF can fully compatible with NV-202P.


2. What is the bandwidth requirement for an IP Device connection?


In WAN, as long as the bandwidth is not enough, it will drop frames.
Based on GOP and actual image sizes, there is no recommended bandwidth.
On Video Setting, suggest setting up CBR in order to select an appropriate Video Bitrates.


No matter with a web browser or a mobile phone that connects to Streaming1 or Streaming2, the connection limit is based on each model. And, each connection shares the bandwidth.
H.264 IP CAM︰the connection limit is 10.
JPEG video format︰Require at least 30KB/second. There is no CBR Setting with JPEG mode.


3. How to use NTP?


1. Build the IP Device in WAN with a real IP.
2. Enable NTP, then it will adjust the time automatically.


4. Firmware Update Steps.


Firmware Update Steps︰ 
Access IP Device Configure → System Update → Firmware Update, then browse and upgrade firmware.


1. With incomplete firmware or unstable network connection, it will damage the IP Device.
2. Do not turn off the IP Device during firmware upgrade procedure. The procedure time might take 1 or 2 minutes.


5.  IP Installer cannot search the IP Device or it cannot connect with the IP Device thru the web browser.


1. Set the IP Device with DHCP. After the IP Device gets a DHCP IP, use IP Installer to search it again. Then, just assign it with a static IP manually.
2. Or use Cross Over to connect the IP Device with PC in order to exclude network environment issues.
3. In WAN, confirm Router’s Web Page Port is enabled and corresponding to the IP Device’s.
4. In LAN, if IP Installer can search the IP Device, but it cannot be connected thru the web browser, make sure the first 3 sections of the IP Device IP Address and PC IP Address must be the same.


For example,
IP Device IP Address︰192.168.30.X
IP Device Gateway︰
PC IP Address: 192.168.30.X

If IP Installer still cannot search the IP Device thru Cross Over, it might be hardware broken.


6.  PoE and Power Adapter applications.


1. Can [PoE] be used with [Power Adapter] together?
2. When both [PoE] and [Power Adapter] are connected to an IP Device, which one has the first priority to provide power supply?
Answer︰The one is with higher voltage. Actually, both are 12V. However, [PoE] voltage depends on the distance of the [PoE] cable. As long as the [PoE] cable is longer, its supplied voltage is lower.
3. If [PoE] disconnects, can an IP Device have power supply via [Power Adapter]?


7. There is an "acmStreamOpen ERROR" message on the web browser.
  1. 1. Make sure the Sound Card is installed.
    2. Make sure imaadp32.acm is set on the first priority. Refer to the step
    as below.

    Control Panel
    - Administrative Tools
    - Computer Management
    - Device Manager
    - Sound, video and game controllers
    - Audio Codecs 
    - Audio Codecs Properties
    - imaadp32.acm
    - imaadp32.acm Properties => Change priority from 1 to 1


8. When SD card is full, will it automatically overwrite?


Yes. When SD card is full, the system will automatically delete the oldest recording files.


9. What is one SD card’s recording time?


Motion Detection, SD card backup, and Mail & FTP setting are processed by Streamin1 so that Streaming1 can set up CBR (on Video Setting). As long as the Video Bitrate is fixed, the user can calculate its recording data sizes.

For instance, use an 8GB SD card.
Video Bitrate [1.5Mbps x (rec.) 10sec.] ÷ 8 (bit → Byte) = 1.875MB/ file.
8000MB (8GB) ÷ 1.875MB = 4266.66 (total file numbers within 8GB)
(4266 x 10sec.) ÷ 86400sec. (total seconds within one day) = 0.49375
If the user uses one 8GB SD card, it can record 0.5 days
