Plan your IP surveillance deployment with confidence

Specifying a commercial IP camera system is nothing like buying consumer security gear. Resolution, frame rate, codec, lens selection, IR illumination, environmental rating, analytics, and licensing all interact — and a mistake in any of them shows up months later as a failed PoE budget, a retention policy that doesn't meet insurance requirements, or a warranty call that isn't covered because a gray-market device slipped into the BOM. We've been selling to commercial integrators since 2014, and we've published the guides below so you can avoid the same mistakes our customers have already run into.

1. Pick the right cameras for your site

Start by mapping coverage goals to camera types. Fixed dome and bullet cameras handle 80% of commercial installs, but they're rarely the right answer for wide atriums (multi-sensor beats PTZ), low-light parking lots (look for Lightfinder-class sensors), or high-traffic entrances where you need license-plate capture. Outdoor-rated cameras need IP66+ and IK10 housings at minimum; thermal cameras solve detection cases where visible light won't work. Our camera selection guides walk through the decision tree for each case.

2. Build a network that keeps up

A camera system is a bandwidth and power system first, and a video system second. Budget your PoE headroom with at least 30% margin using the PoE budget calculator; choose managed PoE+ or PoE++ switches with per-port monitoring for troubleshooting; and use surveillance-grade UPS on NVRs and core switches so a brown-out doesn't corrupt your last 30 days of footage. Smart compression (H.265, Zipstream, WiseStream) can cut your storage needs in half — see the H.265 vs H.264 guide for real-world numbers.

3. Size storage to your retention policy

Retention is the silent killer of most quotes — storage cost grows with camera count × resolution × frame rate × retention days, and it compounds fast. If your retention is dictated by state law (cannabis dispensaries, for example), you need a cushion for growth. If it's insurance-driven, get the policy number attached to the project folder. Use our retention & storage calculator for a site-specific number, then size the NVR chassis to match.

4. Don't forget access control and intercom

Most surveillance projects end up specifying a second system anyway: access control (readers, controllers, electronic locks) for doors and gates, or SIP intercom and paging for multi-tenant buildings and large facilities. Building the BOM together means the low-voltage cabling gets pulled once, the network is sized for both systems at the spec stage, and the same VMS/PSIM ties everything together. We carry 2N, Aiphone, and Axis on the intercom side, and HID, Aiphone, and Axis for access.

5. Call before you commit

Spec questions aren't a sales pitch — they're how a senior integrator catches the problem before a truck rolls. Contact the team with your floor plan or product list and get a second set of eyes on it for free.
