Most people start with a number: how many cameras do I need? A better starting point is a question: what do I need to be able to see, and when? The answer changes the position, the lens and the recording setup far more than the count does.
Start with what you need to see
Walk the property and list the points that matter: entry doors, the driveway, the gate, a loading area, a cash desk. For each one, decide whether you need to recognise a face, read a number plate, or just know that someone was there. Each of those asks for a different camera and a different position.
Light and angle decide the picture
A good camera in the wrong place gives a poor image. Backlit doors, glare from glass and dark corners are the usual problems. Mounting height and angle matter as much as resolution, and it is worth checking the view at night, not only in the day.
Recording and who looks at it
Footage only helps if it is recorded, kept for long enough and easy to find. Decide how many days you want to keep, who can view it, and whether you want alerts or only playback. A simple, well-placed system that someone actually checks beats a large one that nobody opens.
