Security Camera Guides: Choose, Install and Troubleshoot

Security Latest / Camera guide directory

Choosing a camera, making it record reliably and getting useful footage are different jobs. Start with the question you need answered, then follow the relevant buying guide or diagnostic sequence below.

This directory brings together our camera, recorder and video-doorbell articles. The two calculators help with storage and running costs; the troubleshooting section separates missed events from recordings that exist but look poor.

I need to fix an existing system

Compare cameras and complete setups

Use a buying guide that matches your constraint. A purchase-price ceiling, avoiding subscriptions and installing where there is no Wi-Fi lead to different comparisons.

Budget and service costs

Connection and hardware choices

Choose storage and work out the costs

Two calculators, two different questions

Use the data and storage calculator to estimate recording space, retention and internet traffic. Use the ownership-cost calculator to compare equipment, installation, subscriptions and maintenance using your own quotes.

The guides explain the assumptions behind the calculations. A monetary estimate is not a measurement of your camera’s actual bitrate, battery life or recording reliability.

Install for the actual property

Follow the layout guide when choosing locations, then use the acceptance checklist to test a proposed position. The remote-property guides cover different power and connection constraints.

Placement and useful footage

Power and remote locations

Find the guide for the symptom

Pick the description closest to what you can observe. A quiet phone, an empty recording timeline and an offline camera do not necessarily have the same cause.

Video-doorbell setup and repairs

Finish with privacy and account checks

The camera-privacy guide covers placement, audio, sharing and jurisdiction-specific examples. The home Wi-Fi guide covers the network around connected devices. Our editorial policy explains how research-based comparisons differ from hands-on testing claims.
