Security camera installation guide: placement, mounting and setup

Last updated October 30, 2026

Step 1: Walk the property and make a camera map

Before buying anything, walk the outside of the property in daylight and again after dark. Sketch the building and mark every door, ground-floor window, gate, driveway and parking area. Then mark how someone would approach each one. Each camera you plan should have a one-line job written next to it, such as “faces of anyone at the back door” or “cars entering the lot.” If a camera does not have a job, you probably do not need it.

Step 2: Choose height and angle

For identification, mount cameras roughly 7 to 9 feet high and tilt them down slightly, so a person’s face fills a good part of the frame as they come through the doorway. Higher mounts are harder to tamper with but show more scalp than face. Overview cameras for lots and yards can go higher, under an eave or on a pole, because their job is to show what happened, not who it was.

Step 3: Plan around light

• Do not aim a camera straight at the sun, a streetlight or a porch light; it will turn people into silhouettes.
• Add motion or dusk-to-dawn lighting where it is dark; even good night vision does better with some light.
• Watch for reflections: a camera behind glass will often show only its own infrared glare at night.
• Check each view at night before you finish.

Step 4: Power and cabling

Wired PoE cameras need one network cable from each camera back to the recorder or switch. Plan the route, measure it, and buy outdoor-rated cable for outside runs. Wireless cameras need either a nearby outlet or a battery plan. Before drilling, check what is behind the wall, especially near electrical boxes and plumbing. Seal every hole through an exterior wall, and leave a small drip loop so water runs off the cable instead of into the building.

Step 5: Mount and weatherproof

Use the right anchors for the surface: brick, vinyl siding and wood all need different hardware. Put connectors inside a junction box or weatherproof housing where you can, and keep the recorder somewhere secure, ventilated and out of sight. Work with a helper on ladders, and do not lean ladders on gutters.

Step 6: Set up recording and the app

1. Change every default password, and turn on two-step sign-in in the app.
2. Set the date and time correctly on every camera and the recorder; footage with the wrong time is much harder to use.
3. Set motion zones so the camera ignores the street and trees.
4. Decide which cameras record all the time and which record on motion.
5. Add other users with their own sign-ins rather than sharing yours.

Step 7: Test, then test again in a week

Walk each approach path and play back the video. Can you recognize yourself? Can you read a plate where you need to? Check again after a week: look for cameras that shifted, clips that cut off early, and alerts you started ignoring because there were too many. The maintenance checklist covers what to do from then on.

When to hire a professional

Consider professional installation for more than four outdoor cameras, cable runs through finished walls or between buildings, any business system where footage may be needed as evidence, or when you want officers to respond to what the cameras see. Our installation includes the walk-through, placement, mounting and cabling, recording setup, phone viewing and a hands-on handoff. Comparing add-on services and camera brands?
