Count necessary views, not bedrooms
Mark entrances and the routes you need to observe. Decide what each image must show. Property area alone does not determine a suitable camera count.
Test detail and overlap
Check the planned view at the relevant distance, including night lighting and glare. One wide view can miss identifying detail; several overlapping views can still leave important gaps.
Account for privacy and operation
Review AEPD guidance, power, network, storage and authorised access. Avoid neighbouring or shared areas unless the installation meets applicable requirements. More cameras can add obligations as well as information.
Specify the purpose of each camera
Use a plan with locations and test criteria before buying. Record what remains unobserved. No residential camera count guarantees full coverage or prevents incidents.
Questions about this guide
Can camera quantity be decided from the number of bedrooms?
No. Plan the approaches and views you need, considering obstacles and the detail each image must show. A floor plan and site assessment are more useful than a bedroom-based rule.
How do I check whether two camera views overlap usefully?
Review the actual images at day and night and walk the intended approaches. Check blind spots and identification detail rather than assuming overlapping angles mean complete coverage.
