How to Position Your Security Cameras for Maximum Coverage
Where you point a camera matters more than how many megapixels it has. This guide covers field-of-view math, the entry-point priority order, mounting height and angle, lighting, storage, and the privacy law you need to know before you drill.
Why position matters more than camera quality
Most home camera installs over-spec on resolution and under-think on placement. A 4K camera aimed at the wrong angle, mounted too low, or pointed into a sunset gives you worse footage than a 2K camera placed well. The job of a camera is to capture a recognizable face and a clear sequence of events at the points an intruder actually uses. That is a placement problem first and a hardware problem second.
Plan the positions before you shop. Decide what each camera is for, where it mounts, what it can see, and how it is lit. Then buy the lens that fits the distance. The Security Camera Coverage Calculator turns your property type and priority zones into a recommended count and a blind-spot estimate so you start with the right number of cameras.
Field-of-view math: what each lens covers
Field of view (FOV) is the angle the lens captures, measured in degrees. A wider angle spreads the same pixels across more of the scene, so it covers more area but reads less detail at distance. A narrower angle concentrates pixels on a smaller patch, so it reads plates and faces far away but leaves gaps to the sides. At a typical mounting height, the approximate ground width a single camera covers grows with both the angle and the height.
- Telephoto, about 60 degrees: Narrow and long. At an 8 ft (2.4 m) mount it sees a corridor maybe 12 ft (3.7 m) wide near the camera but reaches far for plate detail. Best for a long driveway approach.
- Standard, about 90 degrees: The common consumer balance. At a 10 ft (3.0 m) mount it covers roughly 20 ft (6.1 m) of width at a useful distance. Good for a front yard or back door.
- Wide, about 110 degrees: Covers the most width per camera. At a 10 to 12 ft (3.0 to 3.7 m) mount it spreads about 28 ft (8.5 m) wide, ideal for entry clusters and small yards where one camera should see the whole scene.
- Mounting height multiplies width: The higher the camera, the wider the patch it sees at ground level, at the cost of some detail directly below. 8 to 12 ft (2.4 to 3.7 m) is the practical band for homes.
Entry-point priority hierarchy
Cover the places intruders actually use, in order. National crime data from the FBI Uniform Crime Reports and Statistics Canada consistently show entry concentrated at a handful of points. Spend your first cameras here regardless of property size.
- Front door (about 40 percent): The single highest-value camera position. A doorbell camera plus an overhead wide-angle covers the approach, the door, and packages.
- Ground-floor windows and sliding doors (about 30 percent): The most common forced-entry path after the front door. A back-corner wide-angle catches the slider and the windows along one wall.
- Garage side door (about 15 percent): The most overlooked entry point. It is often dark, out of street view, and left unlocked. One camera here pays off.
- Back-yard approaches (about 15 percent): Fence hops, gates, and the path between houses. Cover these once the entry points above are handled.
Driveway and front-approach coverage
The driveway has two jobs that need different cameras. General coverage of who is approaching wants a wide lens for context. Reading a license plate wants the opposite: a telephoto lens aimed straight down the approach, plus enough light to freeze a moving plate at night.
- For context: A wide-angle camera on the garage corner facing the street catches vehicles, people, and the wider scene.
- For plates: A telephoto lens aimed along the driveway line, mounted lower and angled so headlights do not wash out the frame. Plate capture at night usually needs dedicated lighting, not just the camera's infrared.
- Avoid the trap: One wide camera will not read a plate at 30 ft (9.1 m) at night, and one telephoto will not give you situational context. If plates matter, plan for both.
Back yard and side gate coverage
Back yards have dead corners and long fence lines that one camera rarely covers. Mount high on a back corner of the house and aim down and across the yard so the lens follows the fence and the sliding door together. Side gates are choke points: anyone entering the back yard usually passes through one, so a single camera on the gate often covers more than a camera staring at open lawn.
- Use line of sight from the house: A back-corner mount sees two walls and the yard between them, the same way a corner mount works indoors.
- Cover gates, not grass: A camera on the side gate or fence-line path catches the entry, while a camera on open lawn catches little.
- Watch the property line: Fence-line cameras can capture a neighbor's yard. Angle inward and turn audio off at the line. See the privacy section below.
Garage and side entries
The garage side door is the most-forgotten entry point and one of the top three in the crime data. It is usually unlit, out of view from the street, and protected by a weaker lock than the front door. A single wide-angle camera covering the side door and the path to it closes a real gap. If the garage is detached and a cable run is impractical, this is a sensible spot for a battery or solar camera, accepting that it records clips rather than continuous footage.
Mounting height and angle
The sweet spot for most cameras is 8 to 10 ft (2.4 to 3.0 m), tilted 30 to 45 degrees down. That keeps the camera above easy tampering range while still capturing a face-to-feet view of anyone approaching. Two common mistakes wreck otherwise good placements.
- Too high: Above about 12 ft (3.7 m) the camera looks down at the tops of heads and stops capturing recognizable faces. Reserve high mounts for wide context, not identification.
- Pointed at the sun: A camera facing east or west into a low sun blacks out the frame with lens flare for an hour each day. Mount under an eave and aim away from the sunrise and sunset arcs.
- Aimed through glass: An indoor camera shooting through a window suffers infrared glare at night. Mount outdoors or use a model designed for window mounting.
Pairing cameras with lighting
A camera in the dark records dark footage. Lighting and cameras are one project, not two. Plan them together so the lit area and the camera's view line up.
- Color night vision needs light: It produces clothing color, vehicle color, and skin tone, but only with ambient light or an integrated spotlight. Pure infrared gives washed-out black-and-white footage.
- Motion lighting interaction: A motion light that snaps on can briefly overexpose the camera. Aim the light to cross the scene rather than fire straight into the lens, and consider a low dusk-to-dawn level with a motion boost.
- Infrared blast-back: A camera mounted near a white wall or under a white soffit bounces its own infrared back into the lens, hazing the image. Mount away from reflective surfaces.
- Plan spacing with math: The Outdoor Security Lighting Spacing Calculator sets fixture spacing so there are no dark valleys between lights, and the motion vs always-on guide covers the control choice.
Storage: cloud vs local vs hybrid
Where footage is kept decides what survives a power cut, an internet outage, or someone stealing the camera. Cost is per camera per month for cloud, or one-time for local hardware.
- Cloud: About 3 to 15 USD or 5 to 20 CAD per camera per month, or roughly 10 to 30 USD or 15 to 40 CAD for a whole-plan tier. Survives camera theft and total property loss, but needs working internet and is an ongoing fee.
- Local (NVR or base station): A one-time 300 to 600 USD or 400 to 800 CAD records all cameras to a drive inside the house. No monthly fee and works during internet outages, but the footage is lost if the recorder itself is stolen.
- Hybrid: Local continuous recording with cloud backup of motion events. The strongest option and the modern recommendation, at a higher upfront cost.
- Retention and access: Aim for 14 to 30 days of retention (7, 30, and 60 days are the common tiers), confirm the storage is encrypted, and check who can access the account before you commit.
Privacy law: what you can and can't record
Cameras that capture more than your own property, especially with audio, can run into privacy law. The rules differ between Canada and the United States, and audio is treated more strictly than video almost everywhere.
Canada: PIPEDA, provincial law, and the OPC
PIPEDA, the federal privacy law, governs commercial use of personal information, so it applies if you run a home business. Purely personal and residential recording falls under provincial Privacy Acts instead. British Columbia (Privacy Act), Alberta (Personal Information Protection Act), and Quebec (Law 25, formerly Bill 64, with expanded enforcement scope since 2023) have the strictest residential rules. The Office of the Privacy Commissioner (OPC) guidance for home cameras is straightforward: point them at your own property, avoid capturing a neighbor's home or yard, and post signage if you record audio. Recording a neighbor's private space can expose you to a civil complaint even where no criminal law is broken.
United States: two-party-consent audio and state privacy law
Video of public-facing areas is broadly allowed, but audio is restricted. Twelve jurisdictions are two-party-consent (all-party consent) for recording conversations: California, Florida, Illinois, Maryland, Massachusetts, Michigan, Montana, Nevada, New Hampshire, Pennsylvania, Washington, plus the District of Columbia. Disable two-way audio on any camera that can capture a conversation beyond your property. CCPA-style consumer privacy laws in California, Virginia, Colorado, Connecticut, and Utah extend further protections. Finally, a homeowners association (HOA) may have its own rules about visible cameras and where they can point, so check the bylaws if you are in one.
Common mistakes
- Over-watching one zone. Three cameras on the front door and nothing on the back leaves the second-most-common entry point blind.
- Pointing at the sun. An east or west camera blacks out for an hour at sunrise and sunset. Aim away from the sun's arc.
- Recording the neighbor's property. Angle cameras inward and down so they capture your own yard, not theirs.
- Two-way audio at the fence line. It can break two-party-consent rules. Turn audio off at the property line.
- No signage where it is required. If you record audio, post a notice. It is both courteous and, in some provinces, expected.
- Cloud-only with no local backup. An internet outage means no recording. Keep at least a local copy of critical cameras.
- Default passwords. Leaving the factory password is how cameras get pulled into the Mirai botnet and similar attacks. Change it on day one and update firmware.
DIY vs installer decision
DIY suits 2 to 4 cameras that are either fully wireless or run to an outlet, where the hard part is mounting and aiming, not cabling. Bring in an installer for 5 or more cameras on PoE, for any roof-mount work, or where cable has to cross finished walls and attics. The cost difference is large: DIY is your time and no labor charge, while a professional install runs about 150 to 400 USD or 200 to 500 CAD per camera depending on cabling difficulty. A practical middle path is to DIY the easy positions and hire out the roofline and the cable runs.
Whichever route you take, plan the positions first with the coverage calculator and the placement worksheet, and choose the hardware with the camera buying guide.
FAQ
How many cameras does a typical house need?
Most homes are well covered by 4 to 6 cameras: the front door or doorbell, the driveway or front approach, the back door, and a back-yard wide angle. Small lots can be fine with 2 to 3 cameras on entry points, while large lots and acreage with outbuildings can need 6 or more. Use the Security Camera Coverage Calculator to size the count from your property type, lens, and priority zones.
Can I legally record my neighbor's yard?
Aim cameras at your own property. In Canada, Office of the Privacy Commissioner guidance for residential recording is that cameras should capture your own property, and provincial Privacy Acts in British Columbia, Alberta, and Quebec (Law 25) add stricter rules. In the United States, twelve jurisdictions are two-party-consent for audio, so disable two-way audio at any camera that faces a neighbor or the street. Incidental capture of a sliver of a neighbor's property is generally tolerated, but deliberately pointing a camera into their windows or yard is not.
Are Wi-Fi cameras or PoE cameras better for DIY?
Wi-Fi cameras are easier to install because there is no cabling, but they depend on signal strength and can drop during interference. PoE cameras run a single cable for power and data, record continuously, and are far more reliable, but they need cable runs to a switch or recorder. For DIY, Wi-Fi suits 2 to 4 cameras and renters; PoE suits 5 or more cameras and anyone comfortable running cable in an attic or basement.
How long should I keep recorded footage?
Fourteen days handles most theft and vandalism scenarios, and 30 days is comfortable and the common default. Less than 7 days means a one-week vacation can outlast the recording window. Match storage capacity to your camera count and resolution, and write the retention period down so it is intentional rather than whatever the SD card happens to hold.
Do security cameras lower home insurance premiums?
Sometimes. Many Canadian and US insurers offer a small discount, often around 2 to 5 percent, for a monitored alarm system, and some extend it to cameras or a full smart-home security package. The discount is rarely large on its own, so treat lower premiums as a bonus rather than the reason to install cameras. Ask your insurer what specific equipment qualifies before buying.
Bottom line
Position beats megapixels. Cover the entry-point hierarchy first, mount at 8 to 10 ft (2.4 to 3.0 m) angled down, match the lens to the distance, light every scene, and keep cameras pointed at your own property with audio off at the line. Size the plan with the Security Camera Coverage Calculator, lay it out on the Security Camera Placement Worksheet, and score the whole property with the Home Security Score Calculator.
