Introduction
1.1
Overview The Pelco Viewer ActiveX Control is designed to integrate Pelco cameras into the Vijeo Citect system. The Pelco Viewer ActiveX Control allows access to and control of Pelco RTP and RTSP cameras via the standard Microsoft ActiveX Controls. This enables system engineers and integrators to access and control Pelco IP cameras on SCADA runtime pages. The target audiences for this document are system engineers, system integrators, intermediate and advanced Vijeo Citect users. In order to use examples provided in this document and develop new Cicode to access and control Pelco IP cameras, the Pelco Viewer ActiveX Control must be installed on the computer.
1.2
Scope This document is restricted only to Pelco Viewer ActiveX Control interface for system engineers, developers and system integrators to integrate Pelco cameras into Vijeo Citect / CitectSCADA / CitectFacilities projects.

How to…...:
2.1
Choose a computer for video streaming Video image processing traditionally is a CPU, physical memory and video memory intensive application, and the Pelco camera ActiveX Control is no exception. Consequently, a high performance computer is recommended for running Pelco ActiveX Controls on a Vijeo Citect client, especially when a large number of concurrent video stream connections is required. This interface supports both DirectX and GDI technology. DirectX has an advantage over GDI where the video stream rendering is handled by an external processor and RAM configuration on the graphics card. Based on our testing, DirectX is recommended for the video stream and the following recommended hardware is required for a computer that is used as a Vijeo Citect client running Pelco camera video stream via DirectX. The display adapters specified were the ones that we tested and that worked well. Some graphics cards provided poor quality video and, in some circumstances, loss of colour and pixilation. Table 2 – Recommended hardware for running the Pelco camera interface

ATI Radeon HD 3450 - Dell Optiplex NDVIA GeForce Go 7400 ATI Radeon HD 3450 Pro
1 GB or more
Note: We recommend that you run the Pelco interface on dedicated SCADA clients and not on any of the SCADA servers, i.e. I/O, Alarm or Report Servers.
2.2
Check graphic card-dedicated video memory Graphic card-dedicated video memory is required to run a DirectX video stream. Graphic card-dedicated video memory is displayed differently on Vista and XP. On Vista, it is displayed separately, whereas on XP, it can be displayed either separately or together with other types of video memory, depending on your computer type. Please refer to Microsoft documents for more details. In order to determine the amount of dedicated video memory on the graphic card: > Click Start → Run > Type desk.cpl and click OK button > The following window is displayed:
4
On XP, click on Settings tab Click Advanced Setting button as indicated above Advanced Setting window will be displayed Click Adapter tab
On Vista, graphic card-dedicated video memory will be indicated as below:
Note: In this example, Video Memory is 0MB; DirectX will not work.
On XP, the graphic card-dedicated video memory can be indicated either separately or together. In the example below, graphic card-dedicated video memory is indicated as “Memory Size”, which is 512 MB, because the computer is a desktop.
5
2.3
Find Pelco camera IP address In order to determine the IP address of your camera, you have to use the Pelco Device Utility. The Pelco Device Utility can be found on the resource CD which is shipped with the camera. For information about how to install the Pelco Device Utility, please refer to the Pelco manual. > > > >
Click Start → Programs → Pelco → Device Utility → PelcoDeviceUtility Pelco Device Utility should start as below Your camera’s IP address will be shown after the Pelco Device Utility has started If the camera’s IP address is still not shown then:
Click on the “Search Now” button and your camera IP address should be shown as below. If your camera’s IP address is still not shown, please make sure it is connected to your network and that the camera is not blocked by your network. In some cases, the addresses are blocked by network administrators or local network rules.
2.4
Find Pelco IP camera port number Pelco IP cameras usually have default ports of either 49152 or 49157. A different port number can be assigned. For further information, please refer to the Pelco camera manual. Alternatively, reset the values to the factory defaults with the reset button on the camera.
2.5
Find Pelco IP camera number In a majority of cases, the default number is 1. If the camera is used in conjunction with a Pelco DVR, then the camera number is assigned on the DVR.
6
2.6
Check camera availability from a computer There are two ways to check the availability of a camera from your computer: Option 1 Click Connect button from the Pelco Device Utility as indicated below:
Option 2 Open Microsoft Windows Internet Explorer and type in the camera’s IP address in the URL field and enter. e.g. http://10.176.234.163 > The login window should be displayed. > Log in with your user name and password, and the defaults are admin and admin, if you have not changed them. > After the first successful login, you will be prompted to install an ActiveX control on your computer. Accept it and install the ActiveX control on your computer. > Once the installation is completed, your camera should be connected and video should stream in your browser. > If there are any problems, please refer to your Pelco manual or contact Pelco support to fix this before proceeding further with the project.
2.7
Use PelcoPlayer to test video streaming As part of the installation, a command line debug window is available called PelcoPlayer. This window contains all the messages when connecting the video stream to ActiveX control. There is a test utility called the Pelco ATL Viewer. In order to test whether the Pelco ATL Viewer ActiveX control works on your computer, a few steps are required: > Ensure that all required software has been installed on your computer. For more details, please refer to the Pelco Camera and SCADA Integration Quick Start Guide. > Click Start → Programs → Pelco → PelcoCamera → PelcoPlayer > Two windows will be displayed as shown below: PelcoPlayer, which is a debug window, and Pelco ATL player, which is the actual video stream viewer.
7
> Click the Configure button , which is at the bottom left corner, as indicated above, to open Network Stream Setting window. To connect to an RTP camera, check the RTP mode radio button and enter all fields as indicated below and click the Connect button.
Video will be streamed in the Pelco ATL Player as shown on the right. To connect to an RTSP camera, check the RTSP mode radio button and enter the Sarix camera’s URL, as indicated below, and click the Connect button. Note: It is essential that either stream1 or stream2 are specified on the URL, as shown below.
The camera should be connected as above on the right. 8
The connection and debugging information will be also shown in the debug window, as shown below right:
2.8
Use SCADA tags to manage Pelco camera properties To be able to connect to a Pelco camera from Pelco Viewer ActiveX Control in SCADA runtime, camera connection information is required to be specified to an object of Pelco Viewer ActiveX Control. To store those camera property values or connection information, SCADA tags can be created to manage them. The table below contains all camera properties, equivalent SCADA tag data types and valid values for your reference. For details about how to create Vijeo Citect tags, please refer to the Vijeo Citect manual. Table 3 – Camera/Pelco Viewer ActiveX Control properties

Add Pelco Viewer ActiveX Control in a SCADA project To be able to view Pelco camera real-time images in SCADA runtime, we need to add Pelco Viewer ActiveX Control to a page: > Open Graphics Builder. > Open an existing or a new page where the Pelco camera real-time images are required in SCADA runtime from the toolbar button, as indicated below:
> Click add ActiveX button as indicated on the toolbar:
> Insert ActiveX Control window is displayed. Select Pelco Viewer and click Insert button.
> Pelco Viewer Properties window will be displayed.
> Map all the relevant properties of the camera to the SCADA variable tags that were created previously based on the table below. An example has been provided above with the sarixURL.

> After all the relevant properties and tags have been mapped, an Object Name has to be defined as below. This name will be used in the camera connection function. > Click OK to close the Pelco Viewer Properties window and a blank viewer window is now inserted on the SCADA page. Save the page.
2.10 Set camera connection properties Any Vijeo Citect method can be used to manage tags to set or change camera connection properties. The example below uses a button to take user input and save it into the previously created tag. > Create a Button object next to Pelco Viewer ActiveX Control, and set the properties as below:
11
> Add a Text object next to the Button object, and set the properties as shown to the left.
> Copy and paste both Button and Text objects. > Modify the pasted objects’ properties to button text from RTSP Mode to RTSP URL, and tag from sarixM to sarixURL. Please note that both tags need to be defined in the project. > Ensure that the modified input command is changed as shown. > Save the page.
¾
2.11 Connect and disconnect Pelco cameras Both RTP and RTSP cameras use the same connect and disconnect methods. The differences between them are in the connection properties. It is necessary to call Connect and Disconnect methods of the Pelco Viewer ActiveX Control object in order to connect or disconnect the camera. In the example below, two buttons are added to call those methods. > Using the previous example, add Connect and Disconnect Button objects next to Pelco Viewer ActiveX Control, and set the properties as below:
> > > > > > 12
Ensure defined Up command: _ObjectCallMethod(ObjectByName("PelcoCam"), "Connect"); Save the page and project. The completed page will look similar to the page below. Compile and run the project and open the camera page. Set the camera properties. Connect the camera by clicking the Connect Button. The camera’s video image should be shown on Vijeo Citect runtime similar to the following page.
> To disconnect the camera, simply click on the Disconnect button.
2.12 Configure Pelco integration with a SCADA project Video rendering can be a CPU, physical memory and video memory intensive application. Therefore, we recommend using a dedicated computer to run Pelco camera video streaming, especially if there are four concurrent camera video streams on one page. The best SCADA configuration is to run Pelco camera video streaming on a dedicated high performance computer as a control or web client.
2.13 Change Pelco camera PTZ speed If the Pelco camera model being used supports pan, tilt and zoom, such as the Spectra IV IP camera, the speed of PTZ can be adjusted using the Pelco Viewer ActiveX Control in SCADA runtime. There are two properties in the ActiveX control which can be used to adjust horizontal and vertical velocity. Any Vijeo Citect method can be used to manage and adjust camera velocity properties. The example below uses a button to take user input and save it into the previously created tag. > On the previous page, double click on the inserted Pelco Viewer ActiveX Control. Pelco Viewer Properties will be displayed. > Check the VelocityHorizontal property and insert the tag you created previously for this property, as below:
> Repeat above steps to map the VelocityVertical property to the tag you created, as above. > Click the OK button to save changes.
13
> On the previous page, add a Button object next to the Pelco Viewer ActiveX Control and set the properties as below:
> Enter the Cicode in the Up command field, as indicated above: hVelocity = Input("Velocity Horizontal","Enter the VelocityHorizontal", hVelocity). > Add a Text object next to the newly added Button object, and set the properties as below:
> Repeat above steps to create Button and Text objects to input Velocity Vertical. > Save the page. > Page should appear like this when completed: > Compile and run the project. > Open the page and click the button; enter the new value you wish to change and click OK to save it. > The PTZ speed should be changed after this. For more information, please refer to the quick start guide.
2.14 Change Pelco camera video stream bandwidth Pelco camera video steam bandwidth can also be adjusted like the PTZ speed. The only difference is that a different ActiveX control property is used for controlling bandwidth. The property is called Bandwidth. Follow the procedure from the previous example to map the previously created tag to this property, and then create Button and Text objects in the same way to manage user input. The default value is 0, which is the maximum bandwidth. For more information, please refer to the quick start guide.
14
2.15 Manage maximum no. of concurrent camera streams Video streaming with DirectX requires a lot of CPU, memory and especially dedicated on-board video memory. The more dedicated on-board video memory, the more concurrent video streaming connections can be supported. Also, it is important that you ensure that your concurrent video streaming connections are not too high, as that will cause the application to suffer poor performance, slow responsiveness and even unavailability. Based on our testing, if the maximum number of concurrent video streaming on the same page does not exceed the number below, depending on your computer’s dedicated video memory, you should experience reasonable video steam quality, performance and responsiveness. Table 5 – Recommended max. number of concurrent video streaming on a page

2.16 Use Cicode to control camera Pelco Viewer ActiveX Control comes with a group of programming interfaces which can be accessed via Cicode. There are two examples below to demonstrate how to use Cicode to control your camera through the programming interface. For more details about all programming interfaces of Pelco Viewer ActiveX Control, please refer to the document “Pelco Viewer ActiveX Control Interface Guide”, which is installed under the installation directory selected during the installation. Example 1: In this example, we embedded a Cicode command in a Button object named Left that will control the camera to pan left at runtime.
Here are the actual Cicode commands used: _ObjectCallMethod(ObjectByName("PelcoCam"), "PanLeft"); _ObjectCallMethod(ObjectByName("PelcoCam"), "PanStop"); In this case, when the button is clicked, the camera will pan to the left. The pan left operation stops when your button is released. Please note that “PelcoCam” used in the Cicode function is the object name assigned to the Pelco Viewer ActiveX Control object on the page of your project.
15
Example 2: In this example, we will write two Cicode functions. We can then call these two functions anywhere in the project to do the same job as described above in example 1. FUNCTION RunPanLeft() OBJECT hPelcoPTZ = ObjectByName("PelcoCam"); _ObjectCallMethod( hPelcoPTZ, "PanLeft"); END FUNCTION RunPanStop() OBJECT hPelcoPTZ = ObjectByName("PelcoCam"); _ObjectCallMethod( hPelcoPTZ, " PanStop"); END
2.17 Configure alarm link Configuring an alarm link in the SCADA system for Pelco cameras will provide a convenient way of integrating the SCADA alarm system and Pelco PTZ cameras. The key to implementing a Pelco camera link is to use Cicode to run the “Preset” method provided by the Pelco Viewer ActiveX Control programming interface. An example is provided to demonstrate this feature. In this example, imagine we have a Pelco PTZ camera in the front entrance of an office and a PIR installed to trigger the alarm. The procedure below provides details about how to implement this. > Configure the camera’s preset (e.g. 15) to point to the front entrance where the PIR will be triggered when the area is armed or secured. > Create a digital alarm tag (e.g. PIRTrigged). > Create a digital alarm. > Add a Cicode function as below: FUNCTION FrontEntranceAlarmLink() OBJECT hPelcoPTZ = ObjectByName("PelcoCam"); INT preset = 15; IF PIRTrigged = 1 THEN _ObjectCallMethod( hPelcoPTZ, "PresetRun", preset ); END END > > > > >
If necessary, add a button to toggle the alarm at runtime. Save, compile and run the project. Open the camera page. Make sure the camera is not pointing to the previously configured preset. Trigger the alarm and check the change in the Pelco Viewer.
There is also a good example in the example project “PelcoTest”, which will be installed under the installation directory selected by the installer.
16
2.18 Use Camera Manager In the “PelcoTest”example project provided by the installer, there is a page called Camera Manager. For more information, please refer to Pelco Camera and SCADA Integration Quick Start Guide.
2.19 Set up video streaming to work with GDI It is recommended that you use DirectX as the stream rendering is handled by an external processor and RAM configuration on the graphics card. However, if the system does not have a graphic card with dedicated onboard memory or the computer’s graphic card is not working well with DirectX, then use GDI instead. Please note that the image quality is poor in GDI mode. To use GDI technology, follow the instructions outlined below: > Close down the runtime environment. > Rename the current pelcoapirenderer.xml file in the installed plugin directory to pelcoapirenderer.xmlold. > Rename the current pelcoapirenderer.xml_gdi file in the installed plugin directory to pelcoapirenderer.xml. > Restart your runtime environment.
