QSD2304L DVR User’s Manual
CHAPTER 6 Frequently Asked Questions
Question1:
You have downloaded and installed Network Client software from the DVR. But after inputting DVR IP,
username and password, a message appears: ‘Can’t open codec TVTTH ’.
Answer:
When installing the software, the system registry and system files need to be modified. And if you login to the
system as ordinary user, the modification operation could not be performed. So you need login to the system as administrator
when you install the Network Client software.
Question2:
Why is the backup speed with USB disk is so slow?
Answer:
If you open the Network Client for playing back the record, the backup speed will be slow.
