Video

  • Framerate is to change the number of frames per second. Higher rates will result in smoother videos but will consume more memory and increase the CPU load. If this field is disabled, then it's necessary to set the framerate in the network / ip camera's web interface.
  • Pre buffer is to configure the amount of video data stored before a recording event.
  • Post buffer is to configure the amount of video data stored after a recording event ends.
  • Drop shorter than is handy to filter out short movements.
  • Split longer than can be adjusted to split a recording sequence into multiple files and to limit the buffer size (default value is 1000 frames).
  • Flip-H and Flip-V will mirror the video source horizontally and vertically (to rotate by 180° check both).
  • Source Settings is enabled for capture cards and USB / DV cameras. It displays the camera proprietary general settings dialog.
  • Size & Format can be called to change the wanted video size, format or compression.
  • TV Tuner opens the analog TV tuner dialog.
  • Input Select is used to choose the input of an analog video capture device.

Audio

  • Enable audio recording together with video.
  • Live Listen to hear and check the live audio.
  • For RTSP Network / IP cameras get the audio from the stream.
  • For USB cameras use the Source button.
    The Mixer button is to regulate the levels of the USB cameras.

Recording Save

  • Full video stores the complete sequence in .mp4 format. Quality will impact the video appearance of the saved files. Higher qualities result in bigger files with better visual quality.
  • Small video stores a summary of the full video with the configured size.

Live Snapshot

  • Under Take each the live snapshot rate is set; those snapshots are used for the web interface live view. Usually 1 second rate is fine, setting this to Fast will result in a smoother preview, but at the expense of more network bandwidth usage and increased Hard Disk / SSD write operations.
  • Press the Thumbnail Size button to adjust the live snapshot thumbnail size which is also the web interface live view size.

Control

  • For each camera there is a batch file to control ContaCam externally, its path is shown in the text box and can be copied to the clipboard (use right-click menu).
  • That batch file can be run to change the sensitivity at certain times of the day or to turn OFF the recordings at other times.
  • Use the Windows Task Scheduler to manage the batch file execution, read more here.

Command

  • It can be chosen when to execute the command: 1. With the first frame on Recording start, 2. After the Recording saving is done, 3. When the Live snapshots saving is done or 4. After the Daily summary saving finished.
  • In Program box provide the full path of the executable to be run.
  • Under Arguments fill the optional parameters using also variables.
  • Hide window of executed command should only be checked if the executed command closes itself when done.
  • Only one instance of executed command instructs ContaCam to wait that the current command terminates before executing a new one.
  • Under Examples there are helper buttons to setup typical commands.
  • Attention: batch files have to be invoked through cmd.exe
    Program
    C:\Windows\System32\cmd.exe
    Arguments
    /C ""C:\Tools\my script.bat" "%full%" "%small%""

Reduce false detections

  1. In the menu of the red dot record button decrease the Motion Sensitivity to 40, 30 or 20.
  2. Increase Drop shorter than to 2-4 sec (see above under Video section).
  3. With the Zones (Mask) designer (red rectangles button) erase active zones or draw active zones with lower sensitivity.
    Example: if choosing 50% main sensitivity all the drawn zones will be marked with 50 and will have a sensitivity of 50% x 40 = 20.
