CCTV Camera Placement Guide
Choosing the right camera is only half the battle; putting it in the right place is what makes footage genuinely useful when it matters: clear enough to identify who and what happened, not just that something did. Too high and you see only beanies, too low and vandals knock it off the wall. Aim at a bright window and the lens turns every face into a silhouette, yet point the same camera a metre to the left and you have a crystal-clear image.
Because most of us don’t think in fields of view or lux levels day-to-day, this guide keeps things straightforward. We pull from hundreds of live ACCL projects and strip the jargon so you can walk your own site, spot the weak spots and brief your installer confidently.
Why Camera Placement Matters More Than Megapixels
Modern 4 K cameras are brilliant, but resolution means little if the angle is wrong. Imagine recording a burglary where the thief’s cap hides every distinguishing feature because the camera sits too far above the doorway. Placement is what turns “footage” into “evidence.” Get it right and you answer three questions every investigator asks: Who? What? How?
Start with Your Security Priorities
Before you even fetch a step-ladder, note down the assets or events you need to protect:
- Cash tills and safes
- Main entrances and emergency exits
- Loading bays and stock rooms
- Car parks and bike shelters
- Data racks or laboratories
By listing priorities, you focus budget on cameras that really matter. A designer can always add more, but the first ten should protect the biggest risks.
The Golden Rules of Practical Placement
1. Cover Entrances at Face Height
Doors are where people slow down, look up for signs or swipe an access card. Mount a camera around 2.3 m (roughly a tall person’s eye-line), angled slightly down. You’ll capture clear facial features without hats or hoods blocking the view.
2. Avoid “Hot” and “Cold” Lighting
Cameras struggle if half the image is in bright sun and half in deep shadow. If a doorway faces south and bakes in July sunlight, move the camera just inside the lobby looking out, or fit a small canopy outside to soften the contrast.
3. Overlap Fields of View
Think of camera coverage like circles on a Venn diagram; where they overlap, you remove blind spots. Two cameras on opposite corners of a warehouse aisle give you front and rear views, so no forklift ever blocks both angles at once.
4. Keep Infra-Red Clear at Night
Night-vision LEDs bounce light off nearby surfaces. If the first thing they hit is a white wall half a metre away, the image will be one giant flare. Position outdoor cameras so the nearest obstacle is at least two metres away.
5. Protect Against Tampering
Outdoor cameras should sit out of easy reach (around 3.5 m high) yet still close enough to show faces. Indoors, use anti-tamper domes for low-level shots in corridors where ladders aren’t practical but teenagers’ fingers might be.
Typical Camera Types and Where They Shine
- Dome cameras: Great for receptions and corridors; their smoked covers hide exactly where the lens points.
- Bullet cameras: Perfect for car parks; the longer body often houses a big lens for detail across open ground.
- PTZ cameras (pan-tilt-zoom): Ideal for large yards but best paired with fixed units so nothing is missed when the PTZ looks elsewhere.
- Fisheye cameras: Cover an entire small office with one lens, which is good for open-plan spaces where cabling points are limited.
Choosing the right body style often allows better placement because you’re working with the camera, not against its limits.
Indoor vs Outdoor Placement Tips
Indoors
- Mount slightly lower; ceilings rarely offer climb-on access.
- Watch for air-conditioning vents blowing dust at the lens.
- Keep away from blinking fluorescent lights to stop rolling lines on the picture.
Outdoors
- Use housings rated IP66 or above; British rain finds every gap.
- Angle slightly down so streetlights don’t blind the sensor.
- If vandals are a risk, consider a vandal-resistant housing with an IK10 rating.
Planning for Growth
Businesses move desks, add walls and change storage racks. Leave spare capacity (either extra cameras or clear cable paths) so new blind spots don’t creep in. A good rule is 10 % spare channels on your recorder and at least one unused data run per floor. It’s cheaper to plan now than retrofit later.
Common Pitfalls (And Easy Fixes)
Mounting too high: Drop to 2.5 m indoors; your evidence improves overnight.
Ignoring privacy zones: If neighbouring offices or the public highway appear in frame, enable privacy masking on the camera menu.
Relying on digital zoom: Zooming after the event enlarges blur. Get the framing right at install time instead.
When to Call in a Professional
DIY placement works for a micro-office, but larger sites benefit from measured plans. If any of these apply, consider professional help:
- Multiple buildings or floors
- Strict compliance (pharma, financial services)
- Legacy coax cameras alongside new IP units
- Need for thermal imaging in total darkness (see our Thermal Imaging CCTV Installation service)
- Integration with access control or alarms
Professional designers use lens-calc software to plan for adequate pixel density at the distances that matter. That is a useful starting point for producing clear footage, though real-world conditions (lighting, weather, obstructions) still affect the result.
