Note: 1. You should restart Witness XP before new settings will take effect.
2. Witness DX Pro (CP-400DX Pro) is a real time video/audio system, the task for
compression could possible be taken by either hardware or software. If recording
frame rate is set to “real time” (25/30fps) means hardware takes charge compression
otherwise software takes. The “Image compression quality” setting could take effect
only software compression works.
Record to hard disk & Frequency of save to disk When you enable “Record to hard disk”,
your video clips will be saved to hard disk every few minutes automatically. For example, if
Frequency is “5 minutes”, video clips will be saved every 5 minutes. You can choose from
anywhere between 5 and 30 minutes. Using this option can minimize video clip loss under
abnormal conditions, such as a power outage. If you enable this, it is recommended that you add
a fan for the hard disk because of the additional heat that will be generated.
If you disable this function, video clips will be saved in memory and saved to disk based on your
settings in Camera configuration Æ Recording Æ File (see Chapter 6-2). However, if the
system shuts down abnormally, all clips not saved to disk will be lost.
Start to erase when free space less than Will start to free space on your hard disk when only a
certain amount of space is left on your hard disk. Older files are erased first.
Space to erase each time This specifies the amount of disk space to free when the above limit is
reached. Older files are erased first. As an example, if 800MB is entered, 800MB will be
erased when the limit is reached.
