Use cases
A shop needs faces at the door; a yard needs to know something crossed the fence. Here is what each kind of site needs from the drawing, and where to start.
Retail
Cover the choke points first: the entrance at identify, every till at recognise, the stock room door, then the aisles. Mount heights are low and shelving is tall, so draw the shelves; they are what hides the theft.
From the drawing: identify rings on the door, blind-spot view across the aisles, a schedule the installer can price.
Logistics
Long racking aisles, dock doors and a fenced perimeter. Corridor format pays for itself down the aisles; the yard is a tiling problem with longer lenses, and the perimeter is detection, often thermal, feeding alarms.
From the drawing: overlapping cones on the yard, cable runs back to the cabinet within 100 m, recorder retention sized from the camera count.
Commercial
Reception, lift lobbies, stairwells and the car park, rarely the desks. The work is in the doors: every way in watched at identify, with privacy zones kept off the open-plan floor.
From the drawing: a clean imported plan, identify coverage on every entry point, a live link the facilities manager can check.
Education
Gates, entrances, corridors and the edges of the site, planned under public-sector procurement rules. Specifications increasingly call for NDAA compliance and for a documented rationale for every camera.
From the drawing: a camera schedule naming each maker, blind-spot proof for corridors, a signed-off print for the governors.
Vehicles
Plates at the barrier, people between the cars. A number-plate camera is a narrow lens at a shallow angle with a fast shutter; the rest of the car park is overview coverage from height.
From the drawing: the plate camera's narrow cone checked against the lane, overview cones from poles, cable and PoE budgets to each pole.
Residential
Four to eight cameras: the front door, the drive, the garden gates. The mistakes are mounting too high and trusting night vision past the IR range. The Free plan covers a home project end to end.
From the drawing: a plan traced from a photo or a satellite map, the blind strip under each camera, night ranges that are honest.
Import the plan, place real cameras and prove the coverage before anything is bought.
