I'm a novice in the home surveillance world and have loved this forum to help with most of the issues I've encountered. However, with this particular problem, I couldn't find anything already posted.
I'm building a system that primarily uses POE. Due to cost restraints, I've been scouring ebay for used Dahuas. I found a used DAHUA HDCVI CAMERA A42AG22 (allegedly in full working condition). I was unfamiliar with HDCVI and didn't realize that this camera didn't have a Ethernet port. The 3 ports it has are HD-CVI, power, and CVBS. So after some research, I bought a balun on amazon (link) that connected to the HDCVI and power cable on the camera. I then connected to a POE Cat6 cable, that was connected to a network POE switch and I get nothing. No lights. No power. Nothing.
There's a few possibilities and I would like to get your thoughts
1. I have a wrong balun. It seems that most of the time, people buy baluns in pairs but for my problem, I only need one to get it to a Cat6 cable.
2. Maybe I need a analog to IP converter. I don't know much about HDCVI input but it seems to simple to just hook an analog signal to a balun, and be able to have a digital image
3. last but not least, maybe the camera is busted.
Any suggestions?
