CCTV Installation Guide (2026): Cost, Placement & Pro Checklist
CCTV Installation Guide (2026): Cost, Placement & Pro Checklist

What a “good” CCTV installation looks like (in plain English)
A proper CCTV system should give you:
- Clear images at entry points (faces, not just movement)
- Reliable recording (correct settings, sensible motion zones, enough storage)
- Secure remote viewing (without exposing your system to the internet)
- A clean, safe cable run (not DIY spaghetti across the roof)
- A proper handover (admin access, passwords, instructions, warranty)
If you don’t get those outcomes, it doesn’t matter how many cameras you bought.
Retail wireless CCTV vs commercial wired CCTV (what’s actually different)
A lot of people compare “wireless vs wired” like they’re equal options. In reality, they’re often two different categories:
- Retail wireless systems (DIY kits, Wi-Fi cams, battery cams, app-first, sometimes cloud subscriptions)
- Commercial wired systems (PoE cameras, NVR/VMS recording, structured cabling, designed for reliability and scale)
Neither is “always better”. The right choice depends on risk, layout, and how much you care about evidence-grade footage.
Retail wireless systems (DIY / Wi-Fi / battery)
Pros
- Fast to install (often same day)
- Lower upfront cost (minimal cabling)
- Great for rentals or temporary coverage
- App setup is usually simple
- Cloud features can be convenient (alerts, clips, sharing)
Cons
- Reliability depends on Wi-Fi strength and interference (dropouts happen)
- Battery cameras can miss events if settings aren’t tuned (sleep/wake behaviour)
- Limited control over retention and recording quality in many systems
- Often rely on internet/cloud subscriptions for full features
- Can get messy at scale (more cameras = more Wi-Fi load + more failure points)
- Cyber risk rises if accounts/passwords are weak or firmware is neglected
Best fit
- Low to medium risk homes
- Rentals where cabling isn’t allowed
- Quick deterrence and general visibility
- Short-term installs
Commercial wired systems (PoE cameras + NVR/VMS)
Pros
- High reliability (each camera has a dedicated wired link)
- Stable video quality (better evidence, especially at night)
- Scales cleanly (adding cameras doesn’t “crowd” your Wi-Fi)
- Local recording keeps working even if internet drops out
- More control over storage, retention, motion rules and image settings
- Stronger security posture when configured properly (segmentation, controlled access)
Cons
- Higher upfront cost (cabling and labour)
- More install complexity (roof access, wall penetrations, compliance/safety)
- Needs proper design and commissioning (not “plug and play”)
- Not always practical in some rentals or restricted buildings
Best fit
- Businesses and higher-risk homes
- Sites needing evidence-grade footage and longer retention
- Any site where missed footage is unacceptable
- Multi-camera installs (6+ cameras) where reliability matters
The practical recommendation
If you want a simple rule-of-thumb:
- If you want convenience + general visibility, retail wireless can be fine.
- If you want reliability + usable evidence, commercial wired is usually the better choice.
Hybrid approach (often the smartest):
- Wired cameras for critical points (front door, driveway choke point, side gate, cash/stock areas)
- Wireless cameras for secondary angles where cabling isn’t worth it
That gets reliability where it matters without overspending on cabling everywhere.
What drives CCTV installation cost
There isn’t one “standard price” because cost depends on design and difficulty, not just camera count.
The biggest cost drivers are:
- How many areas you’re trying to cover properly (coverage plan matters more than camera quantity)
- Cabling complexity (double-storey, brick walls, long runs, tricky roof access)
- Night performance requirements (cheap cameras fail at night)
- Recorder and storage (how many days you want to keep footage)
- Remote access setup (done securely vs “quick and unsafe”)
- Integration (alarms, access control, intercoms, monitoring)
If two quotes are far apart, don’t ask “why so expensive?” — ask what outcome is different.
Camera placement: the #1 reason CCTV systems fail
Most CCTV systems technically “work”, but fail when you need them because placement is wrong.
The rule that matters
You need identification, not just detection.
That means:
- Capturing faces at entry points
- Capturing choke points where everyone must pass
- Avoiding angles that show the top of a head or a silhouette
Entry point placement tips
- Front door: capture a face as they approach, not after they’re under the eave
- Driveway: cover approach and departure (two angles can be ideal)
- Side access: common “quiet entry” route — don’t ignore it
- Rear doors/sliding doors: often poorly lit, often targeted
- Business interiors: cover cash handling, high-value stock, after-hours entry paths
If an installer can’t explain the placement logic clearly, you’re buying hardware, not a solution.
Choosing the right cameras (what matters and what’s marketing)
Megapixels don’t fix bad setup
High resolution won’t help if:
- the camera is too high
- the subject is too far away
- the image is backlit or washed out
- the lens is wrong for the distance
What matters more than “4K”
- Strong low-light performance
- Wide Dynamic Range (WDR) for glare and bright backgrounds
- Correct lens selection for the distance you need to identify at
- Weather rating and vandal resistance where required
Recording and storage: don’t leave this to chance
Two decisions determine whether your system is useful later:
1) How many days of footage do you need?
A lot of people choose “a few days” then realise incidents get discovered late. Storage should match your risk, not a guess.
2) Motion vs continuous recording
Motion recording is normal, but only works well if it’s configured properly:
- sensible motion zones (avoid trees and roads where possible)
- correct sensitivity
- correct night settings
- correct frame rate and bitrate
A badly configured recorder produces “video” but not usable evidence.
Remote viewing and cybersecurity (do it safely)
Many CCTV “security incidents” come down to lazy remote access setup.
Minimum standards you want:
- Default passwords changed immediately
- Separate user logins (not everyone using admin)
- Firmware kept updated
- Remote viewing set up without insecure exposure
- Admin access removed when staff/tenants change
When reviewing a quote, ask:
“How do you set up remote access, and how do you keep it secure?”
If the answer is vague, treat it as a red flag.
Installation quality: what separates pros from “camera chuckers”
A quality install includes:
- tidy cabling, properly secured
- correct terminations and labelled runs
- clean mounting, correct heights and angles
- correct network configuration
- test and handover with the client
Optional but smart upgrades:
- UPS/power protection to keep recording through short outages
- network segmentation for business sites
- a documented camera plan so future servicing is easy
Quote comparison checklist (steal this)
Before approving any CCTV installation, make sure the quote includes:
- Exact camera models and quantities
- Lens/viewing angle per camera (wide isn’t always better)
- Recorder model and where it will be installed
- Storage size and expected retention days
- Recording settings assumptions (motion/continuous, FPS, bitrate)
- Remote access method
- Warranty (hardware + workmanship) and response time
- Who owns admin access and what happens at handover
- What’s included for cable runs, wall penetrations, patching/cleanup
- Ongoing support options
If a quote can’t answer these clearly, it’s not a professional quote.
Practical next step
To get this right quickly:
- Write down your top 3 risks (break-ins, theft, after-hours incidents, disputes, staff safety)
- Mark entry points and key areas on a rough sketch
- Decide how many days of footage you want retained
- Get a design that maps each camera to an outcome (face, choke point, coverage)
FAQs
How many cameras do I need?
Enough to cover entry points, choke points and high-risk areas. Four cameras can be enough if the layout is simple and placement is smart.
Is wireless CCTV worth it?
For convenience and basic visibility, yes. For reliability and evidence-quality footage, commercial wired (PoE) is usually better.
What’s the biggest mistake people make?
Bad placement and poor night setup. You get motion footage that can’t identify anyone.
Should I get 4K cameras?
Sometimes, but placement, lens choice, and night performance often matter more than resolution.
