Compatible systems offer live viewing and playback through an app. Remote use requires suitable configuration, access permissions and an adequate Internet connection.

There is no single figure for every system. Capacity, camera count, bitrate, compression and recording schedule determine storage duration. Permitted retention must be assessed separately for the use case and applicable rules.

When overwrite recording is enabled, newer footage replaces the oldest files. Behaviour depends on the device and settings. Important footage should be exported promptly.

Choose a card with capacity and speed supported by the camera. High-endurance cards designed for surveillance suit frequent recording. Cards require health checks and have a finite lifespan.

DVRs mainly work with analogue cameras; NVRs work with IP cameras. Hybrid solutions also exist. Signal type, resolution, channel count and compatibility must be checked before upgrading.

Wired connections offer more predictable network communication. Wi-Fi can simplify some placements but is affected by distance, obstacles and interference. Most Wi-Fi cameras still need a power supply.

Power over Ethernet supplies data and power to compatible IP cameras through one network cable. It requires a suitable switch or recorder with an adequate power budget.

Models with infrared illumination or suitable low-light technology can capture images at night. Usable detail depends on the lens, distance, lighting and scene.

Camera count depends on entrances, important areas and potential blind spots. Placement and lens selection matter just as much as the number of cameras.

Without backup power, equipment stops. A correctly sized UPS can keep cameras, the recorder and network equipment running for a limited time depending on the load.

This depends on capabilities and settings. Detection zones, schedules and supported person or vehicle classification can reduce unwanted alerts, but cannot eliminate every error.

Often yes, after checking cables, power and compatibility between cameras and recorder. It may not be possible to retain every existing component.

Check image quality, recording, system time and storage health, and clean lenses appropriately. Frequency depends on the environment and manufacturer guidance.

Useful details include location, property type, entrances, existing wiring and whether you need local or remote viewing. Do not send sensitive access details or passwords.
