Solution
I cannot boot up
the device.
Please press and hold the RESET button down for at least five
seconds to restore factory default setup.
Micro SD card
write times
Do not set the Micro SD card as the storage media to store the
scheduled record file. It may damage the Micro
SD card’s reliability.
I cannot use the
disk as the storage
media.
The HDD disk information details may show either ‘Hibernation’ or
‘Capacity is 0’, if it does please format it first (Via Web).
I cannot upgrade
the device via

When network upgrade operation fails, you can use port 3800 to
continue upgrade.
Recommended
Micro SD card
brand
Kingston 4GB, Kingston 1GB, Kingston 16GB, Transcend 16GB,
SanDisk 1G, SanDisk 4G
Usually we recommend the 4GB (or higher) high speed card as the
slower speed cards may result in data loss.
Audio function
Please use active device for the audio monitor input, otherwise there
will be no audio coming from the client-end.
To guarantee
setup update
After you modified the important setup, please reboot the device via
the software to make sure the setup has been updated to the
storage medium.
Power adapter
The general power adapter has been designed to work within the
0
℃
to 40
℃
temperature range. If the power supply is left in an
environment where the temperature is outside this range, then the
power supplied to the camera will become unstable.
Please replace with an industry-level power adapter if is to be used
in a harsh environment.
I cannot fix the
bracket firmly.
Please use the S3 inner hex wrench to secure the rear bracket
firmly. After the installation please use your hands to test to see if
the camera is firmly in place or not.
SD card error
Re-insert the SD card. If the camera still does not recognise the SD
card the card maybe damaged.
