What to Expect During CCTV Installation

The CCTV Installation Process, Step by Step

You’ve decided to get CCTV for your home. You know roughly what you want. But what actually happens between making that first call and having a working system on your wall?

The process is more straightforward than most people expect. Here’s what it looks like from your side, from initial contact through to checking your cameras on your phone for the first time.

Step 1: The Site Survey

Before any equipment goes up, a good installer will visit your property to do a site survey. This is usually free and takes 30 to 45 minutes.

During the survey, the installer walks the outside of your home and looks at entry points, blind spots, and where cables can be routed. They’ll ask what you’re most concerned about, whether that’s the front door, driveway, back garden, or all three. If you’ve already read our camera placement guide, you’ll have a head start on this conversation.

The survey is also when the installer checks practical things. Where is your broadband router? Is there a power supply near where the recorder will sit? Are the walls solid block or cavity? These details affect how the installation runs on the day.

What to look for: A good installer explains their reasoning. They’ll tell you why a camera works better at one height or angle, not just where they plan to put it. If someone quotes you over the phone without visiting, that’s a red flag.

Step 2: The Quote and Equipment Selection

After the survey, you’ll get a quote. This should include the number and type of cameras, the recorder (DVR or NVR), cabling, labour, and any extras like additional storage or a monitor.

Expect the quote within a day or two of the survey. It should be itemised so you can see what you’re paying for. If you’re unsure about how much CCTV installation costs in Ireland, our cost guide breaks down typical prices.

At this stage, ask about the camera resolution (2K or 4K), whether the system includes night vision, and how many days of footage the recorder stores. A decent installer will explain the trade-offs rather than just pushing the most expensive option.

Step 3: Preparing for Installation Day

Once you’ve agreed on the quote, the installer will book a date. There are a few things you can do to make the day go smoothly.

Clear access to camera locations. If a camera is going above the front door, move bins, planters, or anything blocking ladder access. If a camera covers the back garden, trim back any overhanging branches that would block the view.

Clear space for the recorder. The DVR or NVR usually sits near your router, in a utility room, under-stairs cupboard, or attic. Make sure the installer can reach the spot easily.

Check your broadband. If you want remote viewing on your phone, you’ll need a working internet connection. The recorder connects to your router via ethernet cable, so the router needs a free port.

Let the installer know about any alarms or wiring. If you have an existing alarm system or old cabling from a previous setup, mention it. It might save time.

Step 4: Installation Day

This is where the real work happens. For a typical home setup of 2 to 4 cameras, expect the installer to be on site for 3 to 5 hours. A larger system with 6 to 8 cameras usually takes a full day.

Here’s roughly how the day breaks down.

Mounting the cameras. Each camera gets drilled into position on the wall or soffit. The installer runs cable from each camera back to where the recorder sits. On most Irish homes, cables are routed along the soffit line or through the attic to keep things tidy.

Setting up the recorder. The NVR or DVR goes in the agreed location. The installer connects all the camera cables, hooks it up to power, and connects it to your router.

Cable management. A professional job means cables are clipped neatly, run through conduit where exposed, and not left dangling. If you see loose cables hanging off the wall, say something.

Powering up. Once everything is connected, the installer powers up the system and checks each camera feed on the recorder.

You don’t need to be standing over the installer all day, but it’s worth being around for the start and finish. Check in when cameras are being positioned so you can confirm the angles look right before holes are drilled.

Step 5: Testing and Configuration

Once the hardware is up, the installer configures the system. This includes setting the recording schedule, adjusting motion detection zones, and making sure night vision switches on properly after dark.

What to check during testing:

  • Every camera shows a clear, stable image
  • Camera angles cover the areas you discussed in the survey
  • No major blind spots between cameras
  • Motion detection triggers correctly and doesn’t fire on every passing car or cat
  • Night vision activates and the image is usable in low light
  • The recorder is saving footage and you can play it back

If any camera has a poor angle or blind spot, now is the time to raise it. Moving a camera later means drilling new holes.

Step 6: Handover and App Setup

A good installer doesn’t leave until you’re comfortable with the system. This means walking you through the basics.

You should know how to:

  • View live footage on the recorder and on your phone
  • Play back recorded footage from a specific time
  • Use the app to check cameras remotely
  • Understand what the motion alerts mean
  • Know where the recorder is and how to restart it if needed

The phone app setup usually takes 5 to 10 minutes. The installer connects the system to a cloud viewing platform or a manufacturer app (like Hik-Connect or Dahua DMSS), and you scan a QR code on your phone. If you have a home CCTV system with remote viewing, test it on mobile data, not just Wi-Fi, before the installer leaves.

Timeline: First Contact to Working System

Here’s a realistic timeline for a standard residential installation.

StageTypical timeframe
Initial enquiry to survey2 to 5 days
Survey to quote1 to 2 days
Quote acceptance to install date3 to 10 days
Installation dayHalf day (2-4 cameras) or full day (6-8)
Total1 to 3 weeks

Busy periods like autumn and early winter tend to push lead times out. If you’re planning ahead for darker evenings, book early.

Red Flags to Watch For

Not every installer does a thorough job. Here are warning signs.

No site survey. Quoting without visiting the property means the installer is guessing about cable routes, camera positions, and access.

No itemised quote. A single lump sum with no breakdown makes it hard to compare or question what you’re paying for.

Messy cabling. Cables should be clipped, routed through conduit where visible, and not draped across walls.

No walkthrough at handover. If the installer finishes and leaves without showing you how the system works, that’s a problem. You should be able to use the system independently from day one.

Pressure to skip the details. If someone rushes through the testing or tells you “it’s all grand, just play with it,” push back. You’re paying for a working system and the knowledge to use it.

Your First Week: What to Check

Once the installer is gone, spend the first week paying attention.

Check recordings daily. Make sure footage is being saved and you can find and play back specific times. Storage issues are easier to fix early.

Test remote viewing. Open the app from outside the house on mobile data. If it doesn’t connect, it’s likely a port forwarding or router issue your installer can fix remotely.

Watch for false alerts. Motion detection often needs tweaking. Trees blowing in the wind, headlights sweeping across a wall, or a neighbour’s cat can all trigger alerts. Adjust the detection zones or sensitivity in the first few days.

Check night footage. Wait for a dark evening and review what the cameras capture. Infrared range and image clarity vary. If a camera covers a long driveway but the night image is usable only to 10 metres, you may need an adjustment.

Note any blind spots. After a few days of reviewing footage, you’ll get a feel for what each camera covers and what it misses. Flag anything with your installer while the job is still fresh.

Frequently Asked Questions

How long does CCTV installation take?

A 2 to 4 camera system typically takes 3 to 5 hours. A larger system with 6 to 8 cameras usually takes a full day. Complex setups with long cable runs or difficult access may take longer.

Do I need to be home during installation?

It’s not strictly required for the whole time, but you should be there at the start (to confirm camera positions) and at the end (for testing and handover). Being available in between helps if the installer has questions.

Will the installer need to go in the attic?

Usually, yes. Running cables through the attic is the cleanest way to connect cameras to the recorder without visible cabling on the outside walls.

Does installation damage the walls?

Each camera requires a bracket and a small hole for the cable. A good installer uses appropriate fixings and seals any holes with silicone to prevent water ingress. The holes are small and typically hidden behind the camera bracket.

Can I add more cameras later?

Yes. Most NVRs come with spare channels. A 4-channel recorder supports up to 4 cameras, an 8-channel up to 8, and so on. If you think you might expand, ask for a recorder with extra capacity at the outset. It’s cheaper than upgrading later.

What happens if something goes wrong after installation?

Ask about the warranty and support before you agree to the quote. Most installers offer a 12-month warranty on labour and pass through the manufacturer’s warranty on equipment (typically 2 to 3 years). Get this in writing.
