Hello all,
I'm dealing with an existing camera setup, older Philips B/W cameras and recently purchased a new lorex DVR/network...anyway, the inputs on the DVR are of course BNC, I'm looking for an RJ11 to BNC converter, but my concerns are:

1. is there a standardized pinout for those rj11 ends? Mean to say would a generic rj11 to BNC converter such as this https://www.cctvoverstock.com/cctv2.asp?Model_ID=473&Task=Detail work OR

2. are the pinouts proprietary?...it's an old Philips(Bosch)VS23645T system. the pins are straight through (no Xover).

I don't want to spend $30 a piece (not really my money anyway) on these if they're not going to work.


thanks
