If you’ve never hired a low-voltage or smart-home integrator before, the process can feel opaque. You call someone, describe what you want, and… then what? A good company doesn’t just show up with a van full of equipment. The first real step is a site survey — and if a company skips it, that tells you something.
What a site survey actually is
A site survey is a structured visit to your home or business where the installer documents the physical environment, identifies constraints, and plans the work before any equipment is ordered or any holes are drilled.
Depending on the scope of your project, a site survey might include one or more of the following:
RF site survey (wireless)
For Wi-Fi projects, an RF site survey maps where signal is strong, where it’s weak, and where interference exists. The installer walks the property with a survey tool (or at minimum, a device that measures signal strength and channel congestion) and documents coverage gaps.
This is how you determine how many access points you need, where they should go, and which channels to use. Without it, AP placement is guesswork — and guesswork leads to dead spots in the basement, over-saturated channels in dense neighborhoods along the Wasatch Front, and APs that interfere with each other.
A proper RF survey also identifies sources of interference: neighboring networks, baby monitors, microwave ovens, and the surprisingly common problem of in-floor radiant heat foil reflecting 5 GHz signals in Utah homes with hydronic heating.
Cable pathway survey
For wired projects — structured cabling, security cameras, access control — the survey identifies how cable will physically get from point A to point B.
This means looking at:
- Attic access and clearance (can you actually move around up there, or is it a 12-inch crawl space with blown insulation?)
- Wall construction (wood framing with drywall is easy; concrete block, brick veneer, or steel studs in commercial buildings are harder)
- Existing conduit or cable pathways from previous installs
- Fire-stop locations in multi-story homes (you can’t just drill through these — code requires re-sealing)
- Where the network rack or patch panel will live (basement mechanical room, garage, closet)
- Exterior penetration points for outdoor cameras or cable entry
The goal is to catch problems before the crew is on-site with a drill and a ladder. Discovering mid-install that there’s no pathway from the attic to the garage turns a four-hour job into a two-day job.
Scope-of-work documentation
The output of a site survey is a scope of work: a document that says exactly what will be installed, where it will go, how cable will be routed, what equipment is needed, and what the total cost will be.
A good scope of work includes:
- Equipment list with specific models and quantities
- A diagram or description of cable runs and device placement
- Labor estimate broken out by task (so you know what you’re paying for)
- Any assumptions or exclusions (e.g., “price assumes accessible attic; if we encounter fire-stopping that requires permit work, that’s additional”)
- Timeline for the install
This protects both parties. You know exactly what you’re getting and what it costs. The installer knows exactly what they’re committing to.
Why you should ask for one
Here’s the honest truth: a site survey takes time, and some companies skip it to close the deal faster. They’ll give you a “ballpark” over the phone, show up on install day, and then hit you with change orders when reality doesn’t match assumptions.
A company that does a proper site survey is telling you:
- They’ve done enough installs to know that every house is different
- They respect your time enough to plan the work before doing the work
- They’re confident enough in their pricing that they don’t need to surprise you later
- They’re treating this as a professional engagement, not a side job
What to expect during a site survey
If you’ve never had one, here’s what the visit typically looks like:
- Walk-through: The installer walks your home with you, asking where you want devices, what problems you’re trying to solve, and what your priorities are.
- Physical inspection: They look at attic access, crawl spaces, wall construction, and existing wiring. They might take photos or measurements.
- Discussion: They explain what’s easy, what’s hard, and where tradeoffs exist. (“We can get a camera on that corner, but the cable run is 200 feet — here’s an alternative placement that’s 60 feet and covers the same area.”)
- Follow-up: Within a few days, you get a written scope of work and quote. No pressure, no same-day signing.
The whole visit usually takes 30–90 minutes depending on the size of the project and the property.
When a site survey isn’t necessary
To be fair, not every project needs a full site survey. If you’re adding a single access point to an existing UniFi setup, or swapping a doorbell camera where one already exists, a phone call and a few photos might be enough. The survey matters most when:
- New cable is being run through walls or attic
- Multiple rooms or floors are involved
- You’re building new construction and want pre-wire planned before drywall
- Outdoor cameras need weatherproof cable entry
- You’re not sure what you need and want professional guidance
Red flags if a company skips it
Be cautious of installers who:
- Quote a price over the phone without seeing the property
- Can’t explain how cable will get from the rack to the device locations
- Don’t ask about your attic, crawl space, or wall construction
- Provide a “flat rate” without specifying exactly what’s included
- Rush you into signing before documenting the work
These are signs that the installer is either inexperienced (they don’t know what can go wrong) or deliberately vague (they plan to bill you for surprises).
Bottom line
A site survey is how a professional integrator plans your project before touching your walls. It identifies constraints, eliminates surprises, and produces a written scope of work so you know exactly what you’re getting. If you’re hiring someone to run cable, install cameras, or deploy a network — ask for a site survey. It’s the difference between a project that goes smoothly and one that turns into an expensive improvisation.
Keystone Integration provides free site surveys for homeowners in South Jordan, Draper, Herriman, and across the Wasatch Front. Whether you need Wi-Fi coverage planning, camera placement, or a full structured-cabling scope — the survey is where every project starts.
