Clear two-way communication, added security, and easy package verification make residential intercoms one of the fastest-growing smart-home upgrades. At CountBricks, our estimating platform tracks a 28 % rise in Portland-area requests for voice and video intercom installs this year alone. If you are a DIY-savvy homeowner or a residential contractor, knowing how to install intercom systems for home efficiently will keep projects on budget and on schedule.
• Wired audio only – budget friendly, ideal for small single-story homes
• Wired video – higher security, requires low-voltage cabling
• Wireless Wi-Fi – fastest to deploy, depends on stable network coverage
Walk the property and mark master station, sub-stations, and door stations. CountBricks.com/services offers a free printable site map you can attach to your permit set.
Launch a voice session inside CountBricks software, state the square footage and wall assembly type, and the AI instantly pulls conduit lengths, cable counts, and current labor rates for Portland residential construction.
• Low-voltage fish tape
• 18/2 or 18/4 shielded cable (for wired systems)
• Surface-mount boxes or single-gang cut-in brackets
• PoE injector or 16 V transformer as specified
• Drill/driver with paddle bits
• RJ45 crimp tool for IP video units
• Smartphone with CountBricks mobile app for live cost updates
1. Shut off power at the breaker feeding the transformer location.
2. Pull cable from the transformer to the master station, leaving 300 mm service loops.
3. From the master, branch cabling to each sub-station using star topology.
4. Mount back boxes flush with wall finish; maintain a 1.5 m ergonomic height.
5. Terminate conductors according to manufacturer polarity chart.
6. Energize transformer and test for clear signal; adjust potentiometer if required.
1. Verify at least -65 dBm Wi-Fi strength at door station using a smartphone.
2. Drill a 19 mm chase just above the door trim for low-voltage power feed.
3. Use PoE if available; otherwise, route 18/2 to nearest receptacle box and install the included plug-in transformer.
4. Pair devices through the companion app, then link to the homeowner’s preferred smart assistant.
CountBricks recommends creating a single automation scene named “Entry Check.” When the intercom button is pressed:
• Exterior light turns to 100 %
• Indoor hallway dims to 40 %
• Camera snapshot is stored in a local NAS
All triggers and logic blocks can be generated automatically inside CountBricks Voice by saying, “Create Entry Check routine.”
Traditional estimating tools rely on static price books, but residential construction prices shift weekly. CountBricks pulls real-time supplier APIs so you know exactly what a 100 m spool of 18/4 shielded cable costs today. After your voice walk-through, the system outputs:
• Material subtotal
• Labor hours at current union/non-union rates
• Recommended markup ranges
• Downloadable proposal branded with your logo
Portland requires a minor low-voltage permit for any residential wiring under 50 V. CountBricks users can auto-populate the permit application PDF with one click. National Electrical Code Article 725 covers Class 2 circuits—stay within maximum 100 VA to avoid reclassification.
• Always check for existing electrical or plumbing lines before drilling.
• Use grommets when passing cable through metal studs to prevent abrasion.
• Label transformer breakers clearly; future electricians will thank you.
If drywall repair, masonry coring, or multi-tenant integration is required, schedule a Field Pro through CountBricks.com/consultation. Our crews arrive with pre-synced project data, so no time is lost re-measuring or re-estimating.
1. Conduct a full walk-test calling every station.
2. Record signal strength and latency in the CountBricks punch list.
3. Provide the homeowner with a QR-coded quick-start guide generated in the app.

A recent Cedar Ridge colonial remodel required a six-station video intercom with gate release. The homeowner also wanted seamless integration with existing Z-Wave lighting and a new Wi-Fi mesh network.
During a live voice session, the project manager walked room by room while CountBricks captured square footage, wall types, and preferred device heights. In less than ten minutes the AI generated:
• 245 ft of 18/4 plenum cable
• Two PoE injectors
• Six surface-mount back boxes
• Eight labor hours for a two-person crew
The original estimate was sent on Monday. By Wednesday, copper prices had spiked 4 %. Because CountBricks locks material prices for 72 hours, the contractor avoided unplanned overages and maintained margin.
1. Open-wall phase allowed friction-free cable pulls before insulation.
2. CountBricks punch-list alerted the crew to install grommets at metal stud penetrations, eliminating sharp-edge risk.
3. After final trim, the Field Pro loaded the pre-built “Entry Check” automation. Homeowner acceptance took less than five minutes.
• Zero change orders related to the intercom scope
• 12 % labor savings compared to initial schedule
• Five-star homeowner review added to CountBricks.com/portfolio
• Always reserve 20 % extra cable for multi-story homes—CountBricks adjusts automatically when you mark stairwells in the app.
• Use PoE where possible; it reduces transformer count and troubleshooting time.
• Generate a QR code for system tutorials; homeowners engage more with digital guides than printed manuals.
