Digital Video Recorder - - FAQWhy does my DVR show "Disc Full" but the DVD- R disc still have space? Ans: Because of the hardware design, one DVD- R disc could only backup up to 4. If you want to backup over 4. Note: Our DVD- RW drive only supports "DVD- R" discs. Why does my DVR show HDD full with the usage of only 1. GB, but the HDD total capacity is 2. GB? Ans: It happened when you set up motion trigger recording on the Wavelet series DVRs.
The motion list can only include up to 6,1. The least time to be recorded is 1. So, if you have motion triggered all the time, it will treat as HDD full when the motion list is full.
Why does the OSD on Model AVC7. HDD remaining space, but not the available remaining time? Ans: Because the format of MPEG (not pictures) is different from the format of JPEG (pictures), the available remaining time cannot be calculated. The situation is just like downloading files from the Internet. When you download one file from the Internet, the displayed downloading time keeps changing. For this reason, the remaining time varies dramatically, and users might have the difficulties to precisely know the actual remaining time. Therefore, our R& D team decides to use HDD remaining space instead of the available remaining time.
Why do AVC7. 8X Series DVRs sometimes keep rebooting? Ans: If the physical connection between HDD power cord and HDD is loose, HDD booting will be failed. And in order to let HDD booting successful, the DVR will keep rebooting. If this problem persists always, it's recommended to change another HDD or re- install your HDD. Why can't my USB flash drive be detected? Ans: Press and hold "Menu" first when your DVR is shutdown. Then, press "Power" to boot your DVR.
You can see the firmware version displayed while the DVR is initializing. In addition, there are two MICROM IC in AVC7.
PCB board: One is "Master" and the other one is "Slave". When updating your firmware by replacing MICROM IC, please pay attention to the position of "Master" and "Slave". If you face to the DVR front panel, the IC slot at the left hand side is Master and the one at the right hand side is Slave. Is it possible to access video data on DVR hard disk from your PC? Ans: No. The hard disk of our DVR system can't be accessed from your PC. That's because the system format is designed only for our DVR. How do I make an audio backup?
