Security camera planning guides
Plan placement, field of view, PoE, Wi-Fi, NVR, storage and night vision.
How High Should a Security Camera Be Mounted?
Mount a security camera high enough to discourage tampering, but not so high that faces become small, angled, or difficult to identify. This guide explains how height, lens choice, field of view, lighting, and recording affect real-world coverage.
Read guideSecurity Camera Viewing Angle Explained
Horizontal FOV usually matters most for planning how much wall, driveway, or yard a camera covers. Learn how vertical and diagonal angles, focal length, mounting height, and scene geometry affect useful detail and privacy.
Read guideFixed Lens vs Varifocal Security Camera
A fixed-lens camera is usually the simpler, lower-cost choice when the scene and mounting position are known. A varifocal camera is worth considering when you need to adjust coverage, manage identification distance, or accommodate uncertain installation geometry.
Read guide2.8mm vs 4mm Security Camera Lens
A 2.8mm lens generally covers more area, while a 4mm lens narrows the view and can place more pixels on a distant subject. The right choice depends on sensor size, mounting height, scene geometry, lighting, and whether you need coverage or identification.
Read guideWhat Lens Size Do I Need for a Security Camera?
The right security-camera lens depends on your sensor size, mounting distance, scene width, and the detail you need—not just the lens’s millimeter rating. Use the formulas and placement checklist below to choose between wide coverage and useful identification detail.
Read guideSecurity Camera Field of View Calculator Explained
Learn how focal length, sensor size, distance, and mounting geometry determine a security camera’s field of view. Use practical formulas to estimate coverage without confusing wide visibility with useful identification detail.
Read guideSecurity Camera Frame Rate: 15fps vs 30fps
15fps is often sufficient for general monitoring, while 30fps can preserve more detail during fast movement. The right choice depends on scene activity, resolution, bitrate, lighting, storage, and network capacity—not frame rate alone.
Read guideH.264 vs H.265 for Security Cameras
H.264 is usually the safer choice for broad compatibility, while H.265 can reduce storage and bandwidth when your cameras, recorder, and playback devices support it. The right choice depends on scene detail, bitrate, frame rate, lighting, and your complete recording system.
Read guideCamera Bitrate vs Image Quality
Bitrate is one of the main controls between usable video detail and excessive storage consumption. Learn how resolution, pixel density, frame rate, compression, and night conditions affect the bitrate you actually need.
Read guideWhy Higher Resolution Can Look Worse at Night
More megapixels do not automatically produce clearer nighttime evidence. Learn how sensor size, pixel size, exposure, bitrate, compression and motion affect real-world identification.
Read guideDigital Zoom vs Optical Zoom on Security Cameras
Digital zoom enlarges existing pixels, while optical zoom changes the lens’s view so the sensor can capture a different level of detail. Learn how pixel density, bitrate, lighting, and recording choices affect whether a zoomed image is actually useful.
Read guidePixels per Meter Explained for CCTV
Pixels per meter (PPM) converts a camera’s resolution and field of view into a practical measure of scene detail. Learn how to calculate it, account for distance and perspective, and avoid losing detail through compression or poor night performance.
Read guidePixels per Foot Explained for Security Cameras
Pixels per foot (PPF) shows how much usable image detail a camera places on a target area. Learn how to calculate it and account for lens width, compression, frame rate, and low-light conditions.
Read guideSecurity Camera Resolution for License Plates
License-plate capture depends on pixel density, distance, angle, motion, lighting, and compression—not megapixels alone. Use this guide to plan a camera that preserves usable plate detail.
Read guideSecurity Camera Resolution for Face Identification
Face identification depends on pixel density at the subject—not megapixels alone. Learn how distance, lens choice, lighting, compression, and recording settings determine whether a face is recognizable.
Read guide4MP vs 8MP Security Camera
8MP can provide more identification detail than 4MP, but only when the lens, lighting, bitrate, recording system, and viewing distance support it. Learn when the extra resolution is useful—and when it mainly increases storage and bandwidth demands.
Read guide2MP vs 4MP Security Camera
A 4MP security camera can capture roughly twice as many pixels as a 2MP model, but the practical gain depends on viewing distance, lens, lighting, bitrate, and recording settings. Use pixel density and identification needs—not megapixels alone—to choose between them.
Read guideIs 4K Worth It for Security Cameras?
4K can provide meaningfully more identifying detail, but only when the scene, lens, lighting, storage, and network can support it. Learn when the upgrade is justified and when a well-placed 1080p or 2K camera is the better choice.
Read guideIs 1080p Enough for a Security Camera?
1080p can be enough for monitoring entrances, rooms, and nearby activity, but it may not provide reliable identification at longer distances. Learn how distance, pixel density, lighting, bitrate, and recording choices affect real-world detail.
Read guideSecurity Camera Planning Checklist
Use this security camera planning checklist to define coverage, image goals, power, networking, recording, privacy and installation requirements before you buy. It also highlights compatibility risks that can create problems during installation.
Read guideSecurity Camera for a Warehouse
A warehouse camera system must balance wide-area visibility with enough pixels to identify people, vehicles, and events at important distances. This guide explains camera placement, lens selection, PoE and Wi-Fi tradeoffs, recording, storage, privacy, and compatibility.
Read guideSecurity Camera for a Small Business
Choose a small-business camera system by starting with the areas you need to monitor, the details you may need to identify, and how footage will be powered, recorded, and accessed. This guide explains the practical trade-offs between PoE, Wi-Fi, local recording, cloud storage, image quality, and privacy.
Read guideSecurity Camera for an Apartment
Choose apartment security cameras by coverage goal, power access, network reliability, recording needs, and privacy constraints. This guide explains practical options for renters and owners who want useful protection without complex installation.
Read guideSecurity Camera for a Driveway
Choosing a driveway security camera starts with the area you need to cover and whether you need a broad overview or usable identification detail. This guide compares lens coverage, power, networking, night vision, recording, and privacy considerations.
