I turn on the Digital Video Recorder and nothing happens.:

Check the power LED indicator. If it is on (GREEN) then power is being supplied to the Digital Video Recorder. If the LED is not on, make sure that the power cord is securely connected to a live power source. If the Digital Video Recorder still does not come on, remove the power supply from its compartment, reinsert
it, and try again. If there is still no power, contact your dealer.

There is no image when the DVR is turned on.:

Make sure the power 110V/220V is right, then check the RAM, and then check whether the watchdog reset is wrongly connected.

The display screen is dark.:

Check the Brightness and Contrast toolbar in single view. If the controls are turned too far down, the screen will be dark.
If after trying this, the screen is still blank, try rebooting the Digital Video Recorder by pressing the power on button. If this does not solve the problem, turn the Digital Video Recorder off, wait five seconds, and then turn it back on.
If the problem persists after trying all of these suggestions, turn off the Digital Video Recorder and consult your dealer for a solution.

There is no signal from the cameras.:

Please exchange the signal lines at the back end, thus to judge whether it's wrong with the DVR host.

The mouse can't be operated.:

Please make sure the NumLock key on the keyboard is lighted or not, thus to make sure the machine is working on the right way. And at the same time, press Ctrl+Alt+F2 to switch to literal mode, then the hard disk can be reconfigured; press Ctrl+Alt+F3 to switch back to monitoring screen, then the mouse should be able to be moved; if it still doesn't work, please restart the machine or check whether the mouse is connected well.

The monitoring screen is in right way, but I cannot operate the function of "playback", or the HDD capacity is less than 1GB.:

The HDD is not detected or HDD malfunction.

I can not monitor with Internet Browser.:

The Shield and Gateway in the system settings of the DVR host should be set in right way.

What's the major reason that affects the size of the recording images?:

The setup of camera resolution, compress mode (M-JPEG, MPEG-4, H.264), image quality setting (choosing the images in higher quality means smaller compression ratio, and more space of hard disk will be taken up; the other way round, less space will be taken up) and the content of the recording images will affect the average size of the images.

What's the major reason that affects the length of the recording time?:

  1. The number of camera for recording input, the sum of all cameras’ recording rates, recording mode (continuous recording or motion detection recording), the average size of the recording files, the capacity of the installation hard disk will affect the length of the recording time.
  2. A brief calculating way on the length of recording time: The whole capacity of hard disk / (the average size of the recording files X the sum of all cameras’ recording rates)

The DVR system time is wrong.:

You can set the right time for the system, if it continues to be wrong, enter BIOS to modify BIOS time.
