Where to mount a camera: height, angle, sun and field of view

Where a camera goes matters more than which camera you buy. The same camera can produce a stunning view of a bay or a washed-out picture of a parking lot, depending on a few meters of height and a few degrees of direction. This guide gives you the geometry in plain language: how high, which way, what tilt, and how wide a lens. It works for public webcams and for cameras watching a farm, a boat or a cabin.

Height: higher is almost always better

Height does three things for a live camera. It shows more of the scene, because the camera looks over walls, cars and trees. It keeps people small, which is good for privacy. And it keeps the camera out of reach of hands, balls and vandals.

There is one cost: every camera has a blind zone directly beneath it. If you tilt the camera so the horizon sits at the top of the frame, the nearest ground you can see is at a distance of height ÷ tan(vertical angle of view). The diagram shows a camera 6 m up with a 55-degree vertical view, a common figure for wide lenses.

For a scenic webcam the blind zone rarely matters, because the subject is far away. For a gate, a dock or a boat, mount lower or further back so the subject is outside the blind zone.

Typical heights by purpose

• Security of a door or gate: about 2.5 to 3 m, high enough to be out of reach, low enough to see faces when you need to.
• Yard, farm or dock overview: 4 to 6 m, often on a pole. See mounting on poles.
• Public webcam (beach, square, harbor): 6 m and up, ideally a rooftop, tower or hillside. See camera for a public webcam.
• Skyline, mountain or volcano: the highest point you can safely use, with a zoom lens.

Direction: keep the sun behind the camera

A camera that looks into the sun gets flare, washed-out skies and, over years, a faded sensor. The sun rises in the east, sets in the west and, at noon, sits toward the equator: due south in the Northern Hemisphere outside the tropics and due north in the Southern Hemisphere. So the safest direction for a camera is facing away from the equator.

How high the sun climbs at noon depends on latitude and season: about 90° − latitude + 23.4° at the June solstice and 90° − latitude − 23.4° at the December solstice (Northern Hemisphere). Low winter sun is the problem, because it shines straight into cameras facing that way.

Calculated from solar declination; local terrain and time zones shift the exact times. In the Southern Hemisphere, swap the June and December columns and face south. A camera facing east or west will have the sun in frame at sunrise or sunset. Some owners want exactly that: sunset cams are popular. Then choose a camera with good wide dynamic range and accept a few minutes of flare each day.

Tilt: where to put the horizon

For a scenic view, put the horizon about a quarter to a third of the way down from the top of the frame. Too much sky and the camera exposes for the bright sky, leaving the land dark. Too little sky and the view feels cramped. Keep the horizon level: a tilted horizon is the first thing viewers notice. For security views, tilt down until the area you care about fills the middle of the frame.

Field of view: the formula and the tables

Makers list a horizontal angle of view in degrees (for example, 105° to 31° for a 5x zoom). The width of the scene you see at a given distance is:

Scene width = 2 × distance × tan(horizontal angle ÷ 2)

Then divide the camera’s horizontal pixels by that width to get pixels per meter, the real measure of detail:

Pixels per meter = horizontal pixels ÷ scene width

The levels widely quoted from the video surveillance guideline IEC 62676-4 (2014 edition) help you read these numbers: about 25 px/m to detect a person, 62.5 px/m to observe, 125 px/m to recognize someone you know and 250 px/m to identify a stranger. A public webcam should keep people below “recognize”. A camera guarding a gate may need “identify” at the gate itself.

Worked example: a beach bar webcam

Let’s put the formulas to work. A beach bar wants a live view of its stretch of sand and surf. The roof is 6 m high, and the waterline is about 40 m away. The owner would like to show about 80 m of beach, and nobody should be recognizable.

1. Lens. To show 80 m across at 40 m away, the angle must satisfy 80 = 2 × 40 × tan(angle ÷ 2), so tan(angle ÷ 2) = 1 and the angle is 90°. A wide lens of about 90° is right.
2. Detail. With 1080p, 1,920 pixels ÷ 80 m = 24 px/m at the waterline: people are visible as figures, well below the “recognize” level. With 4K, 48 px/m: sharper waves, still no faces.
3. Nearest people. The bar’s own terrace is 10 m from the camera. At 10 m a 90° 4K camera gives 192 px/m, above the “recognize” level. So the owner tilts the camera up until the terrace is out of frame, or masks it, or chooses 1080p.
4. Direction. The beach faces west, so sunsets will be in frame. The owner accepts that, because sunset is the most-watched hour, and chooses a camera with good wide dynamic range.
5. Blind zone. At 6 m with a 55° vertical view, the camera sees the ground from 4.2 m out. Irrelevant here: the subject is the sea.

Five minutes with a calculator, and the owner knows the lens, the resolution, the tilt and the privacy plan before buying anything.

Special places

• Boats and docks: everything moves. Mount low on the most rigid structure, use stainless hardware and expect salt on the lens.
• Ski areas and mountains: mount under a roof edge or use a hood so snow does not cover the window, and keep the camera out of the path of snow sliding off roofs.
• Farms and fields: poles give height where there are no buildings. Keep the camera away from where animals rub and machinery turns.
• Towns: towers and roofs give the best views and the best privacy. Ask the building owner early; heritage buildings may need permission.

Things to avoid in the frame

• Neighbors’ windows, gardens and doors. Use privacy masks or move the camera. See cameras and neighbors.
• Bright lights at night. A street lamp in frame blinds the camera and draws insects.
• Close walls and eaves at the frame edge. Infrared bounces off them and washes out the night picture.
• Moving foliage close by. Branches in the foreground eat bitrate and trigger motion alerts. Trim them or move the camera.
• Water running down the camera. Mount under an eave or add a sun shield, and form a drip loop in the cable. See weatherproofing.

Practical checks before you drill

1. Stand at the spot (safely) at the time of day your viewers will watch most, and look for sun, reflections and glare.
2. Check how the cable will reach the spot, and how far it is to power and the network. PoE runs up to 100 m.
3. Check the surface: can it carry the camera and mount in wind? See walls and poles.
4. Check access for cleaning. A camera you cannot reach will soon show spider webs.
5. For solar sites, check that the panel spot gets sun in winter, not only in summer. See solar sizing.

Do these next

1. Fix it to a wall or a pole.
2. Seal it properly against rain and dust.
