Frequently Asked Questions


  • What is POE ?
    POE stands for Power-over-Ethernet which is defined in IEEE 802.3af providing up to 15.4 Watt and IEEE 802.3at for high power PoE plus providing up to 25.5 Watt.
    Support for POE means that network IP camera requires only one cable to power the camera and transmit data at the same time (power, video, audio, alarm and control).
    This increases the reliability and reduces the cost of cabling of the entire video surveillance system infrastucture.
  • Which model of CAMoIP camera support POE ?
    All models, including Speed Dome IP PTZ (ANZD), support POE.
    ANWJ and ANW1 could only be powered through POE.
  • What is Wide Dynamic Range (WDR) ?
    WDR stands for Wide Dynamic Range. This feature solves dark shadow when monitoring in condition of strong backlight, ie. bright doorway entrance or window.

  • Which model of CAMoIP camera support WDR ?
    All ANW series and ANZD720 and ANZD820 Speed Dome IP PTZ support WDR.
  • How much Megapixel resolution can network IP cameras output ?
    While supporting Dual-Stream of high and low resolution, i.e. VGA (640x480), Megapixel network IP cameras can output the following high resolution :
    Name Width Height Aspect Ratio Pixel Count
    720p HDTV 1280 720 16:9 1M
    1080p Full HDTV 1920 1080 16:9 2M
    QuadVGA 1280 960 4:3 1.3M
    SXGA 1280 1024 5:4 1.3M
    UXGA 1600 1200 4:3 2M
    QXGA 2048 1536 4:3 3M

    D1 720 480 4:3 0.35M
    VGA 640 480 4:3 0.3M
  • Which model of CAMoIP camera support Infrared ?
    While all CAMoIP's Fixed camera and Speed Dome (IP PTZ) (other than compact dome ANW1) support ICR (for true Day and Night operation), only the following camera models have built-in infrared module: ANWJ, ANWN, ANWM, ANW2, ANW5.
  • What is VBR and CBR ?

    VBR is Variable Bitrate while CBR is Constant Bitrate.
    VBR will be “fixed on Quality”, so the video encoder will output higher bitrate for video with higher complexity/movement while output lower bitrate for mostly static video (i.e. little or no movement).
    When using CBR, the Quality of the video will go up or down, while trying to achieve the desired target bitrate.

    Using VBR will usually better conserve the storage space. It could result in 50% less storage size or double the record duration.
    On the other hand, CBR is more suitable for bandwidth constrained usage since the bitrate is set to meet the bandwidth requirement.
  • How much storage used for 720p or 1080p recording ?
    We recommend using VBR with the following bitrate:
    • Bitrate setting for 720p : 2Mbps @30FPS
    • Bitrate setting for 1080p : 4Mbps @30FPS

    The following table provides the storage requirement for CBR :

  • How do I choose which lenses to use ?
    Camera lens typically has attributes such as focal length and F-stop number, that determine the characteristics of the lens. Depending on the object distance and the width of the area that needs to be viewed, the focal length can be calculated using the following formula:
    The following table is provided for convenience.
    distance (m)
    focal length (mm) for (1/3)" image sensor focal length (mm) for (1/4)" image sensor
    w=3m w=5m w=8m w=10m w=3m w=5m w=8m w=10m

  • Why network IP cameras ?

    Network IP cameras have come a long way, going through many years of development. As a result the technology already matures. These are some of the main features of network IP cameras:

    • Mega-pixel : network IP cameras can output higher detail images compared with traditional analog cameras. It can provide high-definition video (720p, 1080p) and even higher resolution images (3 Mega-pixels or 5 Mega-pixels).
    • Dual-stream : full resolution (high bitrate) for local recording and smaller resolution (low bitrate) for remote viewing
    • POE : Less cabling, single cable to send audio, video, power, and control signal (alarm, PTZ).
    • Leverage existing data network : Install once for many application (i.e. IPCam, IPad, Computer, Phone)
    • 16:9 aspect ratio : extra wide horizontally or vertically when turned 90° (perfect for corridor monitoring)
    • Progressive Scan technology : Sharper image without interline flicker. Ever wonder why the LCD TV with 1080p is more expensive than 1080i (note the small ‘p’ and small ‘i’) ?
    • Scalability : from single-site to multi-site viewing and recording
    • High fidelity : encoding is done inside network IP camera before transmission, so video quality you see is also what quality being recorded (or better because of dual stream)
    • Two way audio : Through Mic, sound in camera surrounding can be recorded. Camera operator can also talk through connected speaker.
    • Longer transmission : up to 100 meters using ethernet CAT5e, couple of kilometers using wireless LAN, tens of kilometers using fiber optics
    • Secure communication : Securely control the network IP camera through HTTPS, 802.1X enterprise authentication
    • Intelligent at camera level : Motion detection comes standard in many network camera, so camera can decide when to send the alarm, what resolution and FPS. Another useful application is tampering alarm due to, i.e. re-direction, spray painting, and or other external damage, camera can send alert to the system.
  • What is the warranty period of CAMoIP Camera ?
    2 years warranty for Fixed camera (ANV, ANW series) and IP PTZ Speed dome (ANZD).
  • Is network IP cameras solution more expensive/costly ?

    For only monitoring usage, IPCam solution eliminates video recorder (NVR/DVR), which save significant cost.
    When occasional record is needed, user could always use SDCard record (inside IPCam) or web browser record.

    When network cable installation already exist, i.e. internet for office/factory, IPCam solution could re-use and save costly new cabling infrastructure.

    With high camera number (above 16 cameras), the TCO (Total Cost of Ownership) of network IP camera solution is lower than analog solution.

    When considering TCO of IP solution, the cost of network IP camera is already 54%, while the cost of cable infrastructure, recording-playback, and labor (installation, configuration) is 6%, 21%, and 19%, respectively.

    While in analog solution, camera cost itself is low but others are high, camera is only 34%, while the cable infrastructure, recording-playback, and labor is 16%, 25%, and 25%, respectively. Please see TCO analysis done by Axis on year 2007 and 2010.

    Feature rich network IP cameras can better meet customer requirement.
