Home Security Cameras: What to Buy and Where to Put Them

Walk into any home improvement store and you'll find an entire aisle of security cameras. Browse online and the options multiply into the thousands. Resolution, field of view, night vision, cloud storage, local storage, wired, wireless, smart home integration — the specs are endless.

Here's the truth: most homeowners don't need the most expensive system. They need the right system, installed in the right places. This guide cuts through the noise.

Before buying anything, it's worth being clear about what cameras accomplish:

Cameras do:

• Deter opportunistic criminals (visible cameras reduce the appeal of your property as a target)
• Document incidents for law enforcement and insurance purposes
• Allow remote monitoring of your property
• Provide peace of mind when you're away

Cameras don't:

• Stop a determined criminal who has already committed to acting
• Replace other security measures (locks, lighting, alarm systems)
• Guarantee police response or prosecution

A camera system is one layer of a complete security approach — not a standalone solution.

1080p (Full HD) is the minimum. 4K cameras produce stunning footage but require significantly more storage and bandwidth. For most residential applications, 1080p or 2K (2560×1440) provides excellent detail — enough to identify faces and license plates — without the overhead of 4K.

Look for cameras with infrared (IR) night vision rated for at least 30 feet. Color night vision (which uses ambient light) is a nice feature but requires some existing light to work. For truly dark areas, IR is more reliable.

A wider field of view (110°–130°) covers more area with fewer cameras. However, very wide angles (150°+) can introduce distortion at the edges. For most entry points, 110°–120° is the sweet spot.

• Cloud storage is convenient and accessible from anywhere, but requires a monthly subscription and depends on your internet connection.
• Local storage (SD card or NVR/DVR) has no ongoing cost and works even if your internet goes down, but footage can be lost if the camera is stolen or damaged.

Best practice: Use a system that supports both — local storage as the primary, with cloud backup for critical cameras.

• Wired cameras (PoE — Power over Ethernet) are more reliable, don't depend on Wi-Fi, and are harder to jam or interfere with. They require running cable, which is more involved to install.
• Wireless cameras are easier to install and reposition, but depend on Wi-Fi signal strength and battery life (for battery-powered models).

For permanent installations, wired is generally preferred. For renters or temporary setups, wireless is more practical.

Camera placement matters more than camera quality. Here are the locations that provide the highest security value:

The front door is the entry point for the majority of home break-ins and package thefts. A camera here should capture faces and the full approach to the door. A doorbell camera (Ring, Nest, etc.) works well here, or a dedicated camera mounted above the door.

Secondary entry points are often less visible from the street — which makes them attractive to intruders. Cover every door that provides access to the home.

The garage is frequently overlooked. A camera covering the garage door and any door connecting the garage to the home is high value.

A camera covering the driveway captures vehicle activity — both arriving visitors and anyone casing the property. This is also your best chance at capturing license plates.

If your backyard is accessible from an alley, neighboring property, or unfenced area, a camera covering the yard and any rear access points is worth adding.

Interior cameras are a personal choice, but for most homeowners, the exterior perimeter provides the most security value per dollar. Interior cameras are most useful for monitoring specific areas (a home office, a safe, a child's room) rather than general coverage.

A camera aimed too high captures rooflines and clouds instead of faces and license plates. Aim cameras slightly downward, angling toward the area of interest.

Cameras are only as good as the light available. If your driveway is pitch black at night, even the best camera will produce poor footage. Pair cameras with motion-activated lighting for dramatically better results.

Eight cameras covering the same areas from slightly different angles is less useful than four cameras covering four distinct zones. Plan coverage first, then buy cameras.

A camera that overwrites footage every 24 hours because the storage is full is nearly useless for incident documentation. Plan for at least 7–14 days of continuous recording, or motion-triggered recording with enough capacity to retain events for several weeks.

Install the cameras, then test them — at night, in rain, from different angles. Adjust placement before you need the footage.

Many homeowners successfully install their own camera systems. But a professional security assessment adds value that DIY research can't replicate:

• Vulnerability identification — A consultant identifies the specific entry points and blind spots on your property, not generic advice from a YouTube video
• System recommendations — Guidance on equipment that fits your actual needs and budget
• Placement optimization — Ensuring cameras cover the right areas with the right angles
• Integration with other measures — Cameras work best as part of a layered security approach

Security Insight Consultants, LLC' residential assessments include specific camera placement recommendations as part of the written report. Learn more about our residential packages.

You don't need to spend thousands of dollars to have effective home camera coverage. A well-planned system of 4–6 quality cameras, placed at the right locations, with adequate storage and good lighting, will outperform a 16-camera system installed without a plan.

Start with the front door, back door, and driveway. Add coverage from there based on your specific property layout and concerns.

If you're not sure where to start, a residential security assessment gives you a clear, property-specific roadmap — no guesswork required.
