 Optimum Replacement for Time-lapse Recorder
Traditional Time-lapse Recorder is a mechanical device. It is very easy to break down after
long-term operation and it causes many problems such as: the overly used magnetic heads
which cause blurred image; tapes need to be changed often and manually; the recording time is
not long enough; the management of recorded tapes is complicated; inefficient when trying to
locate the needed data; recording a huge amount of useless images, etc.
This DVR system adopts digital recording technology. The quality of images will not
deteriorate with time. With its high compression rate, the storage time can last for months
under normal applications. The overwrite operation mode will overwrite the earliest data, and
no more tape change is required. Motion detection function will enable the recording only
when there is motion of the objective, and makes the system and data retrieval more efficient.
 High Reliability
Normal PC digital surveillance system adopts the MS-Windows OS (Operating Systems). Such
kind of system is so often to crash. It usually makes a negative impression which digital
surveillance system is unreliable.
This DVR system adopts Embedded-Linux OS. Our advanced embedded technology condenses
the entire system into a tiny flash module, which makes the system more reliable. Even when
the power fails, the system will re-boot and return to normal operation in less than one minute.
 Longer Recording Days
This DVR system adopts the advanced MPEG-4 compression to store the video images. It
allows you to record more data on the same capacity of hard disks.
