<p data-pm-slice="1 1 []">Regular maintenance helps keep a security camera system operating as intended. Inspect outdoor cameras periodically for dust, dirt, water exposure, loose mounts, and obstructed lenses. Clean lenses using materials recommended by the manufacturer, and check that the camera's view has not changed because of vegetation or accidental movement. Review recording settings, available storage, timestamps, and remote access. Install firmware updates through official manufacturer channels when appropriate, and use strong, unique passwords with additional security features where available. For wired systems, have damaged cables or electrical issues inspected safely. Periodic checks can help identify problems before important footage is needed.
