Walk into any big-box store and you'll see security camera kits for $300–$500. They look easy: "plug and play, no installation needed!" In some cases that's true. In a lot of cases, it isn't. Here's how to figure out which side of the line your project is on — written by someone whose business depends on you choosing the pro install, but who'll still tell you when you don't need one.
For one or two cameras at the front door and back door, a $300 wireless kit from a reputable brand (Reolink, Lorex, even Ring or Nest) is a reasonable starter setup. We've recommended this exact path to neighbors and friends with simple needs.
The moment you go beyond 2–3 cameras, you'll want a central recorder (NVR or DVR) instead of relying on each camera's individual cloud. That means running cables. Running cables means drilling, fishing wires through walls, and dealing with whatever's behind the drywall. Most people aren't equipped — physically or experience-wise — to do this in their own house.
A wireless camera 60 feet from the router with two walls between them will not work reliably. You'll either get dropped video, missed motion alerts, or both. Long-distance outdoor cameras really do need either Ethernet (PoE) cables or dedicated wireless bridges — and that's getting into work that's hard to DIY.
Burglar alarms, fire alarms, electronic access control — these are licensed work in New York State. DIY-ing these is not just a quality issue, it's potentially a code/insurance/legal issue. Some homeowners insurance policies require professional installation for monitored alarm systems.
Cabling between floors or between separate buildings (house and detached garage) is significantly harder than running cable in a single open ceiling. We do this every week and it's still not trivial. Doing it for the first time, on your own house, on a weekend? Tough.
Customers sometimes assume the cost of a pro install is just markup on the equipment. That's not really how it works. What you're paying for:
One option a lot of customers don't know about: hire a pro to design and install the core system, then add DIY-friendly cameras yourself later. We frequently install a 4–6 camera professional system and customers later add Ring doorbells, indoor cameras, or other simple devices on their own. That gets you the reliability where it matters and the flexibility where it doesn't.
If your needs are simple (1–3 cameras, easy locations, good Wi-Fi), DIY is a real option. If your needs are anything more, the labor and expertise costs of a pro install are usually justified. A free estimate from us will at minimum tell you what your project looks like — and whether DIY is realistic for your specific property.
