Subnets, gateways & CCTV: SADP basics
IPv4 basics for installers: matching masks, default gateways, and why /24 vs /23 changes who can see whom.
SADP cannot fix bad math. If you assign a camera 192.168.1.50/24 but the recorder lives at 192.168.2.10, you need routing or a shared L3 interface—not another scan. Teach junior techs to verify mask length, not just the first three octets.
Default gateway choices
Cameras often need a gateway only if you manage them across subnets or pull time from external NTP. Misconfigured gateways can make the web UI sluggish while SADP still sees the device locally.
Document everything
Paste final IPv4 settings into your handover doc the moment they succeed. Future-you will thank present-you.
