A Plain Guide to Recording and Storing Security Video
How security video is recorded, stored and kept: recording modes, storage math, retention, image quality and the trade-offs that shape a practical setup.
Detection and Protection
Video Recording and Storage
Recorders, retention, placement and image quality.
Bandwidth and Network Load From Multiple Cameras
Why several IP cameras can strain a home or office network, how to estimate the load in megabits per second, and ways to reduce it without losing coverage.
Camera Placement Mistakes to Avoid
Common camera placement errors involving mounting height, viewing angle, backlight and lighting, plus simple checks that make footage far more useful.
Doorbell Cameras Compared With Standalone Cameras
A balanced comparison of video doorbells and standalone security cameras: view, power, storage, coverage and the situations where each one works better.
Field of View and Lens Choices
How a camera lens sets the width of the scene and the detail you get, with a worked hypothetical example comparing wide, medium and narrow lenses.
How Long to Keep Security Footage
The factors that set a sensible retention period for security video: storage size, purpose, privacy, local rules and how quickly problems are noticed.
Local Recorders Versus Cloud Storage
Compare keeping camera footage on a local recorder, memory card or remote service: access, loss risks, internet dependence, cost and privacy.
Night Vision and Low-Light Camera Performance
How infrared night vision and color night modes work, what limits them, and what to check in dim conditions: lighting, glare, range and motion blur.
Video Resolution and What It Actually Shows
What camera resolution really means: how pixels, distance and lens width combine to set identifiable detail, with a worked hypothetical example and limits.
