Most small businesses are still running 2015-era analog DVRs locked to a vendor that may or may not exist next year. Here are the four stacks I install in 2026.
Legacy · what you probably have
Analog DVR + cloud lock-in
Coax to a single DVR box, cloud login through whatever app the installer picked. When the installer disappears, the cloud login disappears, the firmware stops updating, and the cameras are stranded.
- Single point of failure (the DVR box)
- Vendor's cloud account = your access
- Firmware patched once, never again
- No phone access if the cloud subscription lapses
Recommended for most small businesses
IP cameras + local NVR + segmented network
PoE IP cameras on an isolated VLAN, recording to an NVR in a locked closet, with a documented router config you keep a copy of. Phone access works whether or not anyone's "cloud" is online.
- Cameras on their own VLAN, segmented from POS / Wi-Fi
- Local-first recording, optional off-site sync
- Standards-based RTSP / ONVIF
- You hold the admin credentials
Hybrid · high-traffic businesses
Hybrid local + edge-cloud failover
Continuous off-site sync of the recordings index to a Cloudflare-fronted backup, fail-open UPS on the NVR, multi-location aggregation for franchises.
- Continuous off-site sync (recordings + config)
- UPS keeps NVR up through 30-minute outages
- Quarterly drift report on hardware health
- Multi-location aggregation
AI-enhanced · the new normal
On-prem AI vision + agent monitoring
A vision-AI worker on a local GPU watches the feeds 24/7. Body recognition, license-plate flagging, after-hours unfamiliar-face alerts, daily plain-English digest. Footage never leaves the building.
- AI runs on your premises
- Quiet rooms run zero AI calls (motion-first gate)
- Alerts only when something actually changes
- Daily summary you read with morning coffee
