I was looking into getting an IP NVR System but came across HD-SDI which has some perks over IP. I've seen the latency problem with IP but I don't know if it applies to me. My scenario... Starting a small business and looking to install 4 cameras at startup and up to 8 camera total in the near future. Length of cable for each camera should be no longer than 40-50ft. Would like to keep my budget around $1000-1500 for NVR/DVR and 4 cameras. Which should i go with IP or HD-SDI.
