Look at the images
Check daytime and night-time views. Clean lenses using the manufacturer’s guidance and inspect for webs, condensation, glare and branches blocking the view.
Check the recording
Review a sample from each camera, confirm the time is correct and test an export. A live picture alone does not establish that footage is being stored.
Review changes
New lights, landscaping and renovated entrances can change coverage. Review disk health, user access and appropriate firmware support as part of maintenance.
