Control Software for EMI Test Equpiment


Monitor showing the PECOS control software for EMC testing
  • Control cameras locally or via network
  • Live view of multiple cameras
  • Recording and replay of videos
  • Interface to EMC test software
  • Event detection to support automated testing

With the HDCon6 PONTIS EMC offers a highly integrated and versatile system to control the shielded CCTV system.

As there is a PC integrated with harddisk, video capture card and multiple in- and outputs (LAN, USB, HDMI etc.) there is no additional PC needed to record and replay the videos.

PECOS, the control software that runs on the HDCon6, gives access to all these features.

To facilitate immunity testing even an event detection is integrated. This safes space, time and cost.

System Control


The software is designed to handle multiple cameras simultaneously. The number is only limited by the size of the screen.

You can also replay recordings in a window, while the live view of other cameras is shown in other windows. Besides the PTZ commands (pan/tilt, zoom/focus) you can also control the iris and other functions via the control panel.


PECOS supports multiple screens with different layouts and also detached monitors, i.e. a second monitor is connected to the PC out of the controller. This is useful to show live view and recordings on different monitors at the same time.


PECOS provides flexible configuration for many features like screens, layouts etc.

Different sizes of the windows allow to show multiple cameras with the main camera in big window and others in smaller ones.

For security reasons different accounts with different rights (e.g. ”replay only“) can be assigned to users with different passwords.

Recording and Replay


With a click you can make a screen shot or start the recording of a camera view.

Both are stored on the internal hard disk and can be accessed via the network for documentation.

Besides the video audio is also stored in the recorded file.


All stored videos can be managed within PECOS. You can view and search in a video. It can be exported to a network location or to a USB stick. Recordings can be converted to different file formats (H.264, MPEG, Avi etc.).


When using preview and fast navigation of timeline you can quickly find recorded video.

When a stored video is replayed a time line is shown below the video. By placing the cursor on the time lime you can see a small preview and jump to the location by clicking. This is very convenient for searches in long time recordings.


PECOS supports synchronous playback of recordings of different cameras that were recorded at the same. So you can have simultaneous videos and audio from different views (e.g. inside the vehicle and outside).

Of course also asynchronous playback of different videos or combining live view with recordings is possible.

Event Detection (optional)

For immunity testing it can be very helpful to automatically detect changes in a certain area of the picture (Region Of Interest – ROI) to detect malfunction of the device under test.

PECOS offers a plug-in with which you can define several areas and the thresholds for the level of the change. In the event of a change above the threshold an alert is created. This alert is also sent out via TCP/IP and a recording is started. It is often very helpful to see what happened before the failure. Therefore PECOS constantly buffers a certain time. When an alert occurs there is already video stored some time before the event. Thus it is possible to see what happened shortly before the event.

Besides the PTZ commands (pan/tilt, zoom/focus) you can also control the iris and other function

The following events can be configured and generate an a alert when detected:

– Motion
When the picture changes to a certain, definable extend an alert is generated. Similar to usual surveillance cameras

– Audio
A frequency range can be defined. If the sound level within that range exceeds a certain level of falls below a certain level it is registered.
Thus a malfunction (above level) or failure (below level, e.g. when a motor stops) can be detected.

– Colour
If one colour of a list of defined (recorded) colours (10) is detected or vanishes.

– Blinking
If a defined colour in an ROI is going on and off, the time in between is registered and alert is generated.

– Character recognition (OCR)
A set of characters (ASCII) can be defined and will be recognized.

– Numeric Vaues
Numeric values in an ROI can be recognized. If the value is above the defined maximum or below the minimum an alert is generated.

Communication Interface


PECOS offers a well designed software interface. Various commands and data can be exchanged via TCP/IP with EMC test software solutions. It is possible to insert text into the picture (e. frequency, level, device name etc.). Recording of a video can be started or snap shots for documentation can be taken.

The interface is well documented and PONTIS will support software suppliers to implement a driver for PECOS.
The documentation is available on request.
For Rohde & Schwarz EMC32 we integrated a custom interface.
