Setup in the right order
- 1
Map your entrances
List the front door, back and side doors, driveway and hidden ground-floor windows. That's where cameras and sensors go.
- 2
Test Wi-Fi at each spot
Stand where each camera will go and run a speed test on your phone. Under about 2 bars or very slow uploads means the camera will drop offline.
- 3
Move the router
Put it central, raised and in the open: not in a cabinet, basement corner or behind the TV.
- 4
Add mesh if spots are still weak
Place a mesh unit halfway between the router and the weak area, not in the dead zone itself.
- 5
Mount cameras high and tilted
About 8–10 ft up, tilted 15–30° down, door near the middle of the frame. Under an eave if you can.
- 6
Check the view at night
Open the live view after dark. Move cameras that face a porch light or street lamp.
- 7
Lock down the accounts
Strong unique passwords, two-factor login on the camera app and router, and auto-updates on.
Why Wi-Fi comes first
Cameras upload video constantly, so they need a stronger signal than a phone does. A camera at the edge of your Wi-Fi will miss clips or go offline, which looks like a broken camera but isn't.
Fix the signal first and every camera you add later just works. For more on speed, see our home Wi-Fi guide.
Router placement in one minute
Central and high beats fast and hidden. Every wall, floor and appliance between router and camera eats signal; mirrors, fish tanks and microwaves are the worst.
If the modem sits in a corner, run a longer cable to move the router, or add a mesh unit toward the cameras.
Camera angles that actually catch faces
Tilt down so the frame reaches the ground a few feet in front of the door. Aim along paths, not straight across them, so people stay in view longer. For zone-by-zone detail, see our camera placement guide.
How we picked
Products were chosen from official spec sheets and priced from each brand's own store. We haven't run hands-on tests. Sale prices change often, so check before you buy.
Home security setup checklist
Common questions
Do I need a new router for security cameras?
Not always. Try moving your current router first. Upgrade or add mesh only if camera spots still show a weak signal.
How much does a basic setup cost?
Using the picks here: two Tapo C120 cameras are about $72 on sale, plus about $200 if you need a single mesh unit. Add microSD cards.
Wired or battery cameras?
Wired for doors near an outlet (no charging, 24/7 recording). Battery or solar where there's no power.
