Q.
: The video picture is too bright and sometimes disappears completely. What is wrong?
A.
: There are two possible reasons:
•
idle video inputs are not deactivated, please refer section 3.3.1;
• the cameras in use provide different video levels (e.g. because of different cable
lengths), please check (and, if needed adjust) the level at the DVR’s jacks by
about 1Vcc.
Q.
: After changing DiREX-Pro settings and clicking the “Apply” button, the old settings
appear. What is wrong?
A.
: You need to change the configuration of temporal internet files of your MS Internet
Explorer. Contents should be updated at “each visit to the site” – please refer to sec-
tion
2.2 of this manual.
Q.
: You assert that DiREX-Pro.40 continuously recording capacity for 6 to 10 days.
However, my device is full after about 3 days. What is wrong?
A.
To offer the highest video quality, our DVRs use the best video processing technolo-
gies available on the market today. Therefore, the better the cameras used (see
section
1.5), the better the digital picture produced. Otherwise, by using cameras with
a low signal/noise ration or/and recording at night without IR backlighting, additional
video noise can be produced that will vastly increase the data rate generated. There-
fore, to avoid recording information, do not increase video quality and resolution (i.e.
higher than the factory defaults) unless the video stream is noticeably improved.
Furthermore, it is recommended to use video noise reduction – please refer to section
3.3.1 of this manual. Please note that the recording of audio signals also reduces the
total recording capacity. It is possible to configure your DVR for sound-controlled
video recording without audio recording (see section
3.3.2).
Normally, the total average transfer rate should be about 80-140 KB/sec (see section
4.1) and the maximum rate at any one time not more than 210 KB/sec.
Q.
: What happens if I connect the following device XXX to DiREX-Pro?
A.
: If you are not a PC professional, we do not recommend you do it!
First of all, it can damage both your device and your DiREX-Pro. Consequently, your
guarantee will not cover it. Furthermore, there is unlikely to be any software supported
by your device in DiREX-Pro. Only the devices described in this manual can be used
with DiREX-Pro, and the corresponding software exists for this.
