Dear Chris/Anton,
it is very easy to switch any DVR from NTSC to PAl video format.
There are uasually one of 3 ways to do it.
First , check the baack of the DVR if there is a microswitch, if you find it then change the position and switch on DVR.
If there is no any switch then ope the dvr and look at the motherboard.You will see some writing there like PAL:ON ,NTSC:OFF and jump-pin next to it.
You need to close it if it is unclosed or unclose if it is closed.
And last option if the 2 above did not help/
There is a combination of 2 or 3 buttons to change the video format.
You need to read manual tech or ask support from the manufacture.
PLEASE KNOW ONE THING :IF DVR ACCEPTS BOTH VIDEO FORMATS NTSC/PAL THEN IT ALWAYS GIVES BOTH VIDEO FORMATS AS WELL
regards,
Ismayil
