I have a Geovision GV 1248 which is a PC based system .
I am not too sure what cameras I have but they were installed back in 2010.
I hear you can get 4k Video over the coax cables, and for convenience, I would rather not rewire the system with CAT5 just yet.
The Cable that I have is Siamese with 12V DC and RG59 with BNC type connectors.
I have a few questions
1) Can someone recommend some cameras or point me in the right direction? I am looking for 4K or better. I have seen some

Are they any good?
2) Will the Geovsion card work with these cameras, or are they defunct?
3) My PSU is 240V to 12V DC and has 24 power rail outputs, I assume that I can still use this for the 12v DC power?
Many thanks
