Security Cameras & Low-Voltage Wiring: Install Them During the Remodel

During the remodel is the right time

Low-voltage cable is nearly free to run when walls, ceilings, and trenches are already open — and genuinely annoying to retrofit afterward: fishing finished walls, crawling attics, surface conduit on the stucco you just paid to paint. That's why we rough-in camera, network, and doorbell wiring on remodels, ADUs, and commercial buildouts by default, even for owners who plan to add the cameras themselves later. Conduit and boxes today; devices whenever you're ready.

Wired PoE vs. Wi-Fi cameras

PoE (power-over-ethernet) cameras take power and data over one cable back to a recorder — no batteries to charge, no Wi-Fi dropouts, continuous 24/7 recording rather than motion clips. That reliability is why every serious commercial system is wired, and why we spec PoE wherever construction access allows. Battery and Wi-Fi cameras have their place — renters, single problem spots, temporary coverage — and hybrid setups (wired core + a Wi-Fi camera on the detached shed) are common and sensible.

What systems cost

• Home, 4–6 PoE cameras + network video recorder (NVR): $1,500–$5,000 installed — resolution, storage days, and cable difficulty drive the spread
• Business, 8–16 cameras with higher-retention NVR: $3,000–$15,000+ depending on building size and ceiling access
• Local NVR storage avoids monthly cloud fees and keeps retention under your control; cloud plans add convenience at $5–$20 per camera monthly
• Add-ons that ride the same wiring: video doorbells, intercoms, access-control door readers, and network drops for Wi-Fi points

For businesses: restaurants, retail, offices

Commercial coverage has a standard playbook: entries and exits, the register and POS area, dining or sales floor overview, the back door and receiving, and any cash-handling office. Many insurers offer premium credits for documented systems, and some landlords and franchise agreements require coverage — worth checking your lease and policy before the buildout so the wiring goes in with the walls. On our tenant-improvement and restaurant projects, camera, alarm, and access-control rough-in is a line item in the same permit set, not an afterthought trade.

Placement and privacy basics

Cover what's yours: entries, driveway, yard, sales floor — and aim away from neighbors' windows and private spaces; courtesy prevents most disputes and complaints. Never place cameras in restrooms, changing areas, or anywhere privacy is expected. Audio deserves special caution: California is a two-party consent state for recording conversations, so most owners run video-only or keep microphones off in areas where private conversations happen — get proper advice before enabling audio, especially in a business. Where signage is customary or required for business monitoring, post it; it's also half the deterrent value.
