Yea, it does not like the graphic card and it is hard to be sure what card will work. There are too many models now....even similar cards might not work all the time And if you find one that works might be buy few as stock.

Server / port info is about the DynDNS server. Not sure what are the actual ones I have not used DDNS for some time. And the port is not the one DVR is using for software remote viewing

Well it works for me http://stackoverflow.com/questions/5550657/calculate-proximity-cards-facility-site-code-to-card-serial-number

Well you need to format the HDD once when you install the DVR at client site and associate the cameras to the HDD (there are advanced configurations possible with HIK VIsion). After that it should work fine. Might be HDD failure here. Put the HDD in PC and with the player (download it from their site) might be able to play the files. They are FAT32 filled with mp4 files

People there is no way to find a reader like that (it is from a competing company) and we are now taking over the maintenance and we need to sell additional cards. Is there a way to calculate the numbers? Are there any relations between the two numbers on the cards? Our readers see the number that is printed on the keytags but this controller is registering the missing unprinted number (there is no space for both numbers on the tags like there is on normal cards)

Yea I know about that but this is old controller and do not save illegal cards. There is no way to see what it sees. I found two neighboring cards (1 number difference) and the same difference is in the second number group (incremented by 1 on both sides). But this not apply on all cards. I think the third short number that is also present/written on some cards should be included in the math. Ideas??

I have problem with some keytags On normal plastic cards there are two set/groups of numbers One that is 10 digits (0-9) and a set of 8 digits (0-9) next to them. The 8 digits group is separated with "," 3+5 digits. Take a lpok at http://76.my/Malaysia/blank-thick-proximity-card-125khz-1006-02-SZXENON@1.jpg Some controllers see the first 10 digits and the other see the other 8 digits group. Now I have keytags that only have the second 8 digits group printed and I need to enter them in the system that reads the first 10 digits. Is there a math that can be done as I can not see the numbers with a reader (the system does not remember illegal cards)
