The 10-step CCTV installation checklist
Installing a business-grade CCTV system isn’t just about sticking a few cameras on the wall. From compliance with the UK’s data-protection laws to calculating switch-port counts and futureproofing your storage, every step needs clear ownership. We’ve pulled together this practical checklist, honed on hundreds of live projects, to help IT leaders and facilities teams deliver a smooth, compliant roll-out and a system you can rely on when you really need it.

1. Define Objectives & Scope
Why it matters: Clear objectives keep scope-creep (and budget-creep) at bay, ensuring the technology actually solves your security problems.
Typical questions to answer
- Risks to mitigate: Theft, health & safety incidents, vandalism, slip-and-trip claims, unauthorised access
- Evidence required: 4K video? Audio? Licence-plate capture?
- Retention period: 30 days for most UK businesses; longer for high-risk sites
- Key stakeholders: Facilities, IT, HR, HSQE, Data-Protection Officer
Action: Document your objectives in a short spec sheet and share it internally before you engage suppliers.
2. Survey the Site & Map Camera Locations
Checklist items
- Walk high-traffic routes, entrances, car parks and blind spots.
- Identify lighting conditions (lux levels day & night).
- Sketch camera fields of view (FOV) to avoid blind spots and GDPR-sensitive areas (e.g. break rooms).
- Note mounting surfaces (brick, metal cladding, suspended ceilings), as they affect fixings and PoE reach.
Tip: Use the free BS EN 50132-7 recommendation of 50 pixels per face for identification-quality images. (See Annex A of the standard on the BSI website.)
Select the Right Hardware
Requirement Hardware Considerations
- Resolution: 1080p (Full HD) minimum, 4K for critical areas
- Environment: IP-rated housings for outdoors; IK-rated domes for vandal hotspots
- Analytics: Look for onboard AI (people counting, line-crossing alerts)
- Lighting: IR LEDs or true-day/night sensors for low-light zones
- Specialist: Thermal cameras for perimeters; See our Thermal Imaging CCTV installation service
Action: Build a bill-of-materials (BOM) early: include camera models, NVRs, PoE switches, patch leads and UPS capacity.
Prepare the Network Infrastructure
CCTV is now an IP workload, so your switches, cabling and firewalls must be ready.
- Cable runs: Check Cat 6 or Cat 6A length ≤ 90 m per permanent link. Longer runs need fibre, a PoE extender or an extended-reach cable system.
- PoE budget: Sum each camera’s draw (e.g. 12 W) × number of devices vs switch budget.
- VLAN design: Segregate CCTV traffic; restrict management to authorised IP ranges.
- Bandwidth planner: 10 cameras @ 4 Mbps each ≈ 40 Mbps sustained, so plan uplinks accordingly.
- Storage calculator: 30 days retention × camera bitrate; our 4K CCTV storage and bandwidth guide works it through.

Installation Phase Checklist
- Mount cameras at planned coordinates; label each clearly.
- Terminate & test cabling (Fluke certification to Class EA recommended).
- Patch each camera into PoE switch ports; record switch/port numbers.
- Commission NVR/VMS: set time sync via NTP, create user roles, enable encryption.
- Position monitors in secure areas (e.g. control room) to avoid unauthorised viewing.
- Walk-test every FOV: check focus, exposure, motion-detection zones.
- Document MAC/IP addresses and keep in a secure configuration file.
Handy tool: ACCL’s team use a “red-pen walk-through” on day one post-install, and any issues are rectified before we hand over. Ask your installer for a similar snag-list process.
Ongoing Maintenance & Health Monitoring
A fault you don’t spot is a liability. Build proactive checks into the annual budget:
- Quarterly camera inspections: lenses, housings, cable strain.
- Monthly firmware & VMS patching, which is crucial for cyber-hardening.
- 24/7 health monitoring: systems like Hik-Central or Milestone’s Device Heartbeat alert you if cameras drop offline.
- Annual audit: confirm DPIA is current and signage still visible.

Cyber-Hardening Best Practices
CCTV breaches hit headlines: default passwords, open RTSP ports, outdated firmware. Protect yours:
- Unique, strong admin credentials on every device.
- Disable unused services (SSH, Telnet) and enforce HTTPS.
- Segment CCTV VLAN: no Internet access unless required.
- Regular pen-tests: build CCTV into your wider cyber-programme.
External reading: The UK’s National Cyber Security Centre publishes guidance on secure-by-design principles for connected devices. See the NCSC blog for best practice.
Decommissioning & Upgrades
Plan for end-of-life:
- Securely wipe drives before disposal (per HMG IA Standard No. 5).
- Recycle or remarket hardware via WEEE-compliant partners.
- Maintain an asset register (camera age, firmware, last service date) to flag upcoming replacements.
Bottom Line
A robust CCTV system isn’t installed in a day: it’s a lifecycle. By following this checklist, IT and facilities managers will not only satisfy auditors and insurers, but also build a surveillance platform that genuinely protects people, property and reputations.
