Quantizer: It’s suitable for the lower exchange rate of video. The file size is smaller, but the CPU
loading will be higher.
Bitrate: It’s suitable for the higher exchange rate of video. The file size is bigger, but the CPU
loading will be lower.
We strongly recommend using Intel iCore 7 or better CPU when you use the H.264 compressor
for continue recording. The H.264 compressor requests more powerful CPU. Therefore, we also
suggest the user to reduce the recording rate when using the H.264 compressor.
Recording setup: When the user enables “Record live video feeds to hard disk”, the video clips
will be saved to hard disk at the set duration time automatically. For example, if you set “5
minutes” for “Frequency of auto-save every” field, the video clips will be saved every 5 minutes.
It’s better to type the duration time between 5 and 30 minutes. This function can minimize video clip
loss under abnormal conditions, such as a power outage. It is recommended to add a fan for the
additional heat in the hard disk. If you disable this function, the video clips will be saved in memory
temporarily and saved to disk based on your settings in “Camera configuration Recording
Recording file size”. However, if the system shuts down abnormally, all video clips will be lost.
Low disk space: It will start to free space on the hard disk when only a certain amount of space is left
on your hard disk. Older files are erased first.
a.) Space to erase at once: This specifies the amount of disk space to erase when the above limit is
reached. Older files are erased first. For example, if you type 1200 MB, the system will erase
1200MB when the limit is reached.
Please setup 9999 MB Space to erase at once when you use the CP-4800DX NVR Card, it can
reduce the HDDs deleted files always.
