Why a Site Survey Matters Before a UniFi Network Installation
A proper site survey cuts installation time, reduces surprises, and helps ensure the final network meets performance and coverage expectations. Whether you’re installing a UniFi network for a multi‑story home, a small office, or a rental property in Virginia, the Outer Banks, or North Carolina, doing some preparation beforehand saves money and produces a more reliable result. This checklist is written for customers working with an independent installer or arranging remote support across the USA.
Before the Installer Arrives — Key Information to Gather
1. Building layout and photos
Provide floor plans if available, or sketch rough layouts showing room names, walls, and levels. Take clear photos of the main living or work areas, mechanical rooms, and the exterior where service enters the building. Photos of attics, basements, and closets where equipment might live are especially helpful.
2. Internet connection details
Record your ISP, the type of incoming service (cable, DSL, fiber, fixed wireless), modem or gateway make/model if visible, and the approximate wall jack or demarcation point where the service enters. Note typical download/upload speeds you see during normal use and whether the location has a public or dynamic IP. If you have a secondary/backup internet option, mention that too.
3. Devices and use cases
Make a short inventory: phones, laptops, streaming TVs, VoIP phones, security cameras, smart thermostats, and building automation devices. Estimate peak simultaneous users and any high‑priority applications (video conferencing, point‑of‑sale, live streaming). That helps the installer size access points and backbone capacity.
4. Constraints and preferences
Mention any HOA rules, historic building restrictions, rental turnover requirements, or landlord permissions. If you prefer equipment concealed vs. visible, or have preferred locations for closets or racks, note that up front.
Physical Prep — What to Measure and Mark
1. Mark preferred access point (AP) locations
Think about where people usually use laptops, phones, or streaming devices. Ceiling centers and hallway ceilings often provide the most even coverage. Mark 2–4 potential AP spots with painter’s tape or sticky notes so the installer can use those as a starting point.
2. Identify cable paths and service entry
Note where Ethernet can run from the network closet to AP locations. Look for accessible attic or crawl spaces, conduits, basements, and existing cable raceways. If a run would need drilling through exterior walls or staircases, flag those locations so the installer can prepare tools and materials.
3. Confirm closet or rack space
Designate where the network switch, UniFi controller (if local), and router will live. A small, ventilated closet, utility room, or a compact wall rack are common. Measure available shelf space and note proximity to an electrical outlet and the incoming service demarcation point.
4. Consider exterior device locations
If you plan on cameras or outdoor APs, point them out and note exposure (covered porch, open deck, dock). While this article doesn’t dive deep into weatherproofing, telling the installer which devices will be outdoors allows them to plan cabling and mounting hardware.
Power and PoE Considerations
1. Check outlets and circuit capacity
Confirm that the designated network closet has grounded outlets and an available dedicated circuit if possible. If multiple PoE devices are planned, a single circuit serving a switch and a small UPS is common. Note any equipment that must stay powered during outages.
2. Decide on PoE switches vs. injectors
Determine whether you want PoE supplied centrally from a switch (neater wiring, easier management) or via inline injectors at each device. Many small sites prefer a managed PoE switch; listing planned PoE devices in advance helps the installer choose appropriate hardware and PoE budget.
Security and Access Logistics
1. Site access and hours
Share information about how the installer will access the property: will someone be onsite, is there a lockbox, or are there restricted hours for work? For rental properties in the Outer Banks or similar vacation areas, coordination around guest turnover is important.
2. Locked closets and permissions
If the network closet is secured, provide keys or codes, or make temporary arrangements. Also let the installer know about any rooms they should avoid or sensitive areas where drilling or cabling is not allowed.
Preparing for Remote Support
1. Controller access and management preferences
If the network will be managed remotely, decide whether you’ll host the UniFi controller locally, in a VM, or use a cloud key. Be ready to provide remote access credentials securely during the support session. Discuss whether the installer should set up multi‑factor access or limited admin accounts.
2. Backups and credential handling
Export or schedule a controller backup ahead of changes so you can restore if needed. Agree on how credentials are shared (temporary, time‑limited access is safer) and whether the installer will leave documentation and a final backup after configuration.
3. Tasks commonly handled remotely vs onsite
Remote support is great for configuration, troubleshooting, and tuning. Physical tasks—running cable, mounting APs, and power work—still need someone onsite. If you’re engaging a remote installer, identify a local contact for physical tasks or plan a follow‑up onsite visit.
Common Site Scenarios and Practical Tips
1. Multi‑story homes
AP placement should consider vertical coverage: one AP per floor is a common starting point, with overlaps in stairwells and central hallways. Mark upstairs and downstairs high‑usage areas and any finished basements that might block signals.
2. Older and masonry buildings
Brick, stone, and thick plaster reduce wireless range. Identify solid walls and large metal objects (elevators, HVAC) that block signals so the installer can plan extra APs or wired drops.
3. Small retail and offices
For point‑of‑sale and back‑office separation, note where retail terminals and staff workstations sit. Indicate any planned VLAN separation or guest network needs up front.
4. Coastal and remote properties (Outer Banks)
Long distances, line‑of‑sight constraints, and property exposure can affect placement and cabling logistics. If you have docks, detached buildings, or long driveways, point them out so the installer can plan for longer runs, conduit needs, or potential wireless bridges.
What an Installer Will Typically Do on Day One
Expect an installer to verify the information you provided, perform a walkthrough, do a basic wireless scan, temporarily place APs for test coverage, run initial Ethernet drops, and confirm power and switch locations. They will usually label cables and document proposed final AP placements. For remote engagements, the first remote session often focuses on controller setup and initial configuration before a physical visit.
Short FAQ
Do I need to be home during the install?
It depends. For installations involving interior work or locked spaces, someone should be present or provide secure access. For purely outdoor or remote configurations, the installer may be able to work without you on site.
How many APs will I need?
The number depends on building size, construction, device density, and use cases. A pre‑site survey helps estimate AP count; installers often begin with a plan and adjust after testing temporary placements.
Will the installer use my existing cabling?
If existing Cat5e/Cat6 cabling is in good condition and correctly terminated, it can often be re‑used. The installer will test each run and recommend replacements for degraded or poorly installed cables.
Can I schedule remote tuning after an onsite install?
Yes. Remote tuning sessions are common to refine channel plans, power levels, and controller settings once the APs are mounted and the network has been in use for a short period.
Independent‑Service Disclaimer
This article is provided by an independent UniFi network installer offering services across Virginia, the Outer Banks (North Carolina), and North Carolina, with remote support available throughout the USA. It is informational only and not an official statement from any manufacturer. Site‑specific factors may change recommendations; consult your installer for a tailored plan.
Preparing ahead lets an installer focus on delivering a reliable, well‑documented network rather than troubleshooting preventable surprises. Use this checklist to make your UniFi network installation smoother and more efficient—whether the work is performed onsite or coordinated remotely.
