    How to Upgrade Camera Firmware through DVR

    To change camera’s setting, the user must approach to the camera to control OSD menu. However, WEBGATE’s PoC cameras support RS485 communications through coaxial cable, making it possible for users to control camera OSD or upgrade firmware from DVR or CMS. This feature allows convenient installations with simple operations and managements. Also non-PoC cameras can be connected with RS485 to control the all the camera’s functions and upgrade firmware.

     

     

    Preparation for Network Upgrade
    (1) Connecting Communication Lines
    PoC cameras do not need additional communication lines. However, non-PoC cameras need to be connected with the RS485 as shown below. Also, DVR and camera upgrade program must be connected via a network.

     

     

     


    (2) Change DVR Configuration
    In case of PoC cameras, change the serial port to “CoC”. In case of non-PoC camera, change the serial port to “transparent”.

     Note.
     If the DVR is connected with multiple cameras, you should accurately set the RS485 ID for each camera.

     


    How to use the Network Upgrade Program
    (1) Run the camera network upgrade program.

     

     

     

     

    (2) Type RS485 ID, DVR Serial Port, User ID, Password, and then press “Connect”.

     - RS485 ID : RS485 ID of camera to be upgraded
     - DVR Serial Port : DVR’s COM port information. In case of PoC, set to CoC.
     - User ID, Password : ID and Password for DVR access

     

     

     


    (3) When connected properly, the status information will be shown as the picture below. If the status does not show the versions, check DVR’s setting and network connection.

     - Connection Status : Serial port opened (It means DVR and camera is properly connected)
     - Status : Main - v1.17.3, Loader - v1.10D (Version of camera firmware)

     


     

     

    (4) Select the firmware file to be uploaded, and then check the box on the left side.


    (5) Click the “Download” button on the bottom to start upgrade.

     

     

     

     

    (6) If the upgrade is proceeding normally, message “Firmware upgrade in progress” will appear and displays the progress bar. However, if the upgrade fail message appears, restart from network connection stage.

     

     

     

     

    (7) When the upgrade is completed, the message “Firmware upgrade is complete!” will be displayed.

     

      

     

     

    (8) Click “Read Version” to check if the firmware has been successfully upgraded.

     

     

     

     

    (9) Click “Disconnect” to disconnect and then exit network upgrade program.

    Using NTP to Accurately Maintain DVR’s Time

    NTP is an abbreviation of Network Time Protocol. This protocol allows equipment/devices to synchronize with accurate time through internet. By using DVR’s NTP feature, the time can be accurately maintained. If DVR can access the internet, it can obtain time information from public NTP server, but if not, the user’s PC or WEBGATE’s DVR can be used as an NTP server.

     

     

    Using public NTP server to synchronize time
    Because DVR has a built-in list of public NTP, by turning NTP feature [ON], the DVR automatically synchronize with the exact time. If the DVR has authorized internet address, and the user has not changed the network setting, turning NTP [ON] would make the DVR synchronize with the exact time as soon as the user closes the menu.

     - NTP time settings must follow the below configuration
     - NTP Mode : Client
     - NTP Server Location : Public 

     


    Using private NTP server to synchronize time
    If DVR cannot access the internet, NTP server can be installed to synchronize with DVR’s time. The user can install UNIX-based server (Linux, etc) to internal network to synchronize time. However, this document will explain how the average user can operate an NTP server with Windows 7.

     

     · Enable Internet Time feature
    Run [Control Panel] – [Date & Time] to enable [internet time feature]

     

     

     


    If the PC is connected to the internet, PC time and internet server will synchronize instantly as soon as the user presses the button, [Update Now]. If the PC is not connected to the internet, [Update Now] will not be synchronize the time. In this case, NTP server will operate based on the PC’s time.

     

     · NTP setting of domain login PC
    If the user cannot see the [Internet Time] on the Control Panel’s [Date and Time], the PC is a domain logged in PC. To use this PC as an NTP server, the user must configure its registry and command as below.

    ① Registry Settings
    HKEY_LOCAL_MACHINE | System | CurrentControlSet | Services | W32Time | TimeProviders | NtpServer | Enable ← change the value 0 to 1.

     

     

     

     

    ② Command Settings
    On Command windows, type “C:>W32tm /config /update”, then “C:>w32tm /query /configuration”. The [Enable] will be set to 1 as shown below.
     

     

     

     

     · Opening NTP firewall port
    When using firewall, go to Control Panel → Run Windows Firewall → Advanced Settings → Inbound rule execution → New Rule, then input below.

     

     

      

     

     Note. UDP 123 is the NTP port that DVR uses.


     · Preparation of DVR
    Modify the NTP settings as below

     

     

     

     

    Set the Mode to Client, then enter the IP address of the PC.

     

     

    Configuration of time synchronization between DVRs
     - If NTP Mode is set to Server, the DVR can work as other DVR’s NTP server.
     - If NTP Mode is set to Client+Server, the DVR can obtain time information from other NTP server and work as NTP server itself to provide other DVRs with time information.
     - If DVR is installed inside the firewall and needs to minimize the connection to the outside, one DVR’s NTP Mode can be set to Client+Server to obtain time information, and remaining DVRs can obtain time information from the Server DVR.

    How to Optimize Camera Setup According to the Environment

    Cameras need to be adjusted to fit the installed environment. The below examples explains variety of ways to optimize camera setup for different environments.

     

     

    Under Backlight Environment
     - When there is a strong backlight where some areas are not distinguishable, please use the WDR(Wide Dynamic Range) feature to compensate this environment. By using WDR, bright/dark environment can be seen clearly at the same time. Depending on the environment, BLC(Backlight Compensation) or HLC(Highlight Compensation) features can be used.
    - However, object ghosting might occur due to installed environment.

     

     

     


    Under Low light Environment
     - When identifying objects are difficult, users can adjust the AGC(Auto Gain Control) value to increase camera’s sensitivity. But surrounding environment will be darker and noise will increase as AGC increase.

      

     

     

     

     - When setting AGC is not enough, use DSS(Digital Slow Shutter) feature. But please take into a consideration that objects will have more ghosting effects depending on the environment.

     

     

     

     

    When Motion Blur Needs to be Minimized
     - Change the shutter mode as below when Day / Night motion blur needs to be minimized.

      Indoor  : Indoor-Anti Blur
      Outdoor : Outdoor-Anti Blur

     - Compared to Anti Blur mode, Indoor / Outdoor mode have enhanced low-light performance. But during day time, both will show same performance level.
     - During night time, if Outdoor-Anti Blur mode does not have enough motion blur effect, then change the shutter to Manual.

     

     

    Under Spot Light Source or Environment where Some Areas are Saturated
     - If the environment is overly bright or some important areas are saturated, please reduce the brightness value.

     

     

    If the Camera is not Expressing the Object’s Inherent Color
     - If installation environment is the reason why the camera is not able to detect the true color, use PRESET function in Color Menu.
     - Place a clean sheet of white pater in front of camera so the entire screen shows white paper. Then press PRESET. In this case, the white balance function will stop, so only use this function where illumination conditions do not change.

    Securing the reliability of DVR recording data by RAID function

    DVR’s recording data is saved in hard disks. So, it is very important to prevent hard disk failure and to prepare countermeasure for failed hard disk.

     

     

    The causes of hard disk failure

    · Head of hard disk writes/reads data without contacting to platter directly. Because the space between head and platter’s surface has micrometer to nanometer, delicate movement of Actuator Arm (it moves head mechanically) is very important. Please refer to [Fig. 1] below.
    · In the following cases, hard disk may broken physically and you may loose the important data.

     - External shock during hard disk is in working
     - Hard disk’s head may raise scratch on surface of platter by sudden stop of power supplying
     - Platter writes data by magnetically, so strong magnetic forces may damage hard disk.
     - Electrical shocks or other causes

    · Besides, internal data may be lose by hard disk’s logical defect.

     

     

     


    Countermeasure for failed hard disk

    1. HD DVR’s RAID function : HD1600/800/400F-PDR, HD1600M-PDR, HD1600/800F-R
    HD1600F-PDR, HD1600M-PDR, HD800F-PDR, HD400F-PDR, HD1600F-R, HD800F-R DVR support RAID level 1, 5, 10 by hardware chipset. RAID stands for “Redundant Array Independent Disk”, and it works to recover the lost data from parity information when problem occurs. Also, WEBGATE DVR’s RAID function supports auto rebuilding function when a new hard disk is installed instead of a faulty hard disk.
    RAID level is decided by number of hard disk(s) installed in DVR as follows.

    · RAID 1 (If DVR has 2 hard disks)
     - It is usually called as “Mirroring”. If a DVR has 2 internal Hard disks, it records same data into two hard disks at the same time. So when one fails, the other can be used to restore the data.
     - It's biggest advantage is its stability, but the available hard disk capacity will reduced in half.

     

     

     

     

    · RAID 5 (If DVR has 3 or 5 hard disks)
     - When configuring RAID system except RAID 0 and RAID 1, some space of each hard disk is used as parity for checking the hard disk errors. In case of RAID 5, certain capacity of each installed hard disk is used as parity checking
     - To configure RAID5, DVR should have 3 or 5 internal hard disks, and available hard disk capacity will be No. of HDD(N)-1.

     

     

     


    · RAID 10 (If DVR has 4 hard disks)
     - Combination of RAID 1’s mirroring and RAID 0’s striping function.
     - DVR should have 4 hard disks to configure RAID 10. Recording data is stored into two hard disks at the same time (RAID 1, Mirroring), and DVR treats Disk 1&2 and Disk 3&4 as a one hard disk(RAID 0, Striping) like the picture below.
     - To configure RAID10, DVR should have 4 internal hard disks, and available hard disk capacity will be No. of HDD(N)/2.

     


     

     


    2. RAID function of external storage : NS04R
    WEBGATE’s dedicated external storage equipment, NS04R can support RAID function same as HD DVR. Up to 4 hard disks can be installed in one NS04R, and up to 8 units of NS04R can be connected by cascade. As a result, they can support total 128TB. (8 units x 16TB/unit)

     


     

     

    3. RAID function of eSATA storage : ES0104, ES02122
    WEBGATE’s HD DVR models support eSATA storage equipment through eSATA port. Available eSATA storage equipment and supported levels are shown at table below.
