Direct answer
The short answer
There is no useful universal camera count. The right number depends on entrances, blind spots, lighting, required detail and the events the property needs to review. WeTech first identifies coverage objectives and then plans camera positions, lens choices and recording requirements around those objectives.
What to confirm for your property
The exact answer can change with building age, wiring, equipment compatibility, resident or staff needs and the final approved configuration. WeTech confirms these conditions during a site assessment instead of making a universal promise from a product sheet.
