How to choose the right CCTV setup for a multi-floor building
A practical buyer's guide for schools, hotels, offices and commercial buildings.
If you manage a school, hotel, office building, church, apartment complex, hospital, shopping centre or warehouse, security is probably one of your biggest concerns.
Unfortunately, many organizations spend thousands of cedis installing CCTV systems that still leave blind spots, record poor-quality footage, or fail when they are needed most. The good news is that these problems are avoidable with proper planning.
This guide explains everything you need to know before investing in a CCTV system for a multi-floor building.
Why multi-floor buildings need a different CCTV strategy
Installing one camera on every floor is not enough. A multi-storey property has unique challenges, including:
- Stairwells
- Elevators
- Long corridors
- Multiple entrances
- Parking areas
- Roof access
- Reception areas
- Emergency exits
- Cash offices
- Server rooms
Each area has different security risks and requires a different type of camera and positioning.
Step 1: Identify your security goals
Start by asking whether you want to prevent theft, monitor employees, protect visitors, reduce vandalism, monitor deliveries, improve safety, or meet insurance requirements. Your answers determine the type of CCTV solution you need.
Step 2: Map every floor
Create a floor plan showing the main and rear entrances, fire exits, staircases, hallways, reception, cash office, server room, storage, parking, elevators and loading bays. This helps determine the number of cameras, cable routes, network switches and storage requirements.
Professional installers always start with a site survey before recommending equipment.
Step 3: Choose the right camera type
Dome cameras
Best for offices, schools, reception areas, hallways and hotels. They are difficult to tamper with, offer a wide viewing angle, look professional and suit indoor use.
Bullet cameras
Ideal for car parks, gates, outdoor walls and building perimeters. They provide long-distance viewing, are easy to point and are weather resistant.
PTZ cameras (pan · tilt · zoom)
Perfect for stadiums, large compounds, warehouses and shopping centres. They can zoom hundreds of metres, be remotely controlled, track movement and cover large areas.
Turret cameras
One of today's most popular choices — offering better night vision, reduced glare, cleaner images and easier maintenance.
Step 4: Indoor vs outdoor cameras
Outdoor cameras need IP66/IP67 weather protection, dust and rain resistance, UV protection and infrared night vision. Indoor cameras focus on image quality, wide viewing angles and discreet design.
Step 5: Camera resolution matters
Older CCTV systems often use low-resolution cameras, making it difficult to identify faces or vehicle registration numbers. Recommended resolutions:
- 2MP (1080p) — small offices and homes
- 4MP — better facial recognition
- 5MP — high-detail monitoring
- 8MP (4K) — large commercial buildings requiring maximum clarity
Higher resolution improves image quality but also requires more storage capacity.
Step 6: Night vision is essential
Most incidents happen outside normal working hours. Choose cameras with infrared night vision, Smart IR, colour night vision (where appropriate) and low-light sensors. Good night performance can make the difference between usable evidence and unusable footage.
Step 7: Decide between DVR and NVR
DVR systems
Used with analogue cameras and coaxial cabling, with a lower initial cost — best for small shops, residential properties and budget-conscious businesses.
NVR systems
Work with IP cameras, deliver better image quality, are easier to expand, support Power over Ethernet (PoE) and offer advanced analytics — best for hotels, schools, hospitals, office buildings and corporate facilities.
Step 8: Estimate storage requirements
The more cameras you install, the more storage you'll need. Storage depends on the number of cameras, recording resolution, frames per second, continuous vs motion recording, and your retention period (e.g. 30, 60 or 90 days). Using efficient compression such as H.265 can significantly reduce storage usage while maintaining image quality.
Step 9: Don't forget the network
IP-based CCTV systems rely on a reliable network. Consider gigabit switches, quality cabling, fibre links between buildings, UPS backup power, VLAN segmentation and surge protection. Poor networking can lead to dropped video feeds and unstable recording.
Step 10: Enable remote viewing
Modern CCTV systems let authorised users watch live video, replay recordings, receive motion alerts and monitor multiple locations from smartphones, tablets or computers. Protect remote access with strong passwords and multi-factor authentication where available.
Common CCTV mistakes to avoid
- Installing too few cameras
- Choosing the cheapest equipment
- Ignoring lighting conditions
- Poor cable management
- No backup power
- Weak passwords
- Not updating firmware
- Failing to maintain the system
A professionally installed system should remain reliable for many years with regular maintenance.
CCTV recommendations by industry
Schools
Prioritise entrances, classrooms (where appropriate), libraries, computer labs, assembly areas and car parks.
Hotels
Monitor reception, corridors, lifts, car parks, service entrances and cash-handling areas.
Offices
Focus on reception, meeting rooms, server rooms, store rooms, parking and building entrances.
Why professional installation matters
A professional installer will conduct a site survey, recommend suitable camera locations, design the network, configure recording systems, secure remote access, test every camera, train your staff and provide after-sales support — ensuring your investment delivers long-term value.
