QCIF
This DVR is capable of recording in QCIF. QCIF is approximately one quarter of CIF
so resolution is very low. The storage space provided however is increased by four
times and an estimate of record time in days can be calculated by multiplying the
above CIF recording time by four.
SPECIAL NOTE
The recording times stated above are only an estimated calculation based on average
file sizes of each frame recorded to Hard Drive. As file sizes can change according to
variation in colours and complexity of the video image captured, MPEG4/H264
reduce storage space according to effective changes between current and previous
image. Therefore please only take the above recording times as a rough estimate.
