How many CCTV cameras does a property need?

UPDATED: 24/10/2023

One of the most commonly thought about questions when considering a CCTV system for a property is how many cameras it requires. In short, there is no one size fits all, but we will attempt to shed as much light on the topic as possible in this post and answer the question.

Property Type Matters: Commercial vs. Residential Security

1. Size and Scale:

When it comes to securing your space, whether it’s a cozy abode or a bustling enterprise, understanding the distinctions between commercial and residential security is crucial. Let’s delve into the intriguing world of property types and their distinct security requirements:

Commercial Security:

    • Commercial properties, with their expansive layouts, often encompass larger areas, multiple floors, and intricate layouts. They are like intricate mazes where every corner deserves vigilance.
    • Businesses typically need to monitor vast spaces, from bustling cash registers to sprawling parking lots. Surveillance must cover extensive territories.

Residential Security:

    • In contrast, the canvas of residential security is usually smaller in scale. Homes come in various sizes, but they often involve fewer rooms and more straightforward layouts.
    • Within a residential setting, the focus may shift to safeguarding spaces like children’s rooms or areas housing valuable possessions.

2. Varied Monitoring Needs:

Commercial Security:

    • Businesses have their unique set of concerns. Commercial security often involves overseeing customer areas, such as hotel lobbies and receptions, to ensure safety and professionalism.
    • Staff-only zones, like stockrooms or confidential workspaces, demand discreet surveillance to protect proprietary information.

Residential Security:

    • Home security, on the other hand, centers around safeguarding personal spaces. Areas like living rooms, hallways, child’s bedrooms, and rooms housing safes require attention.

3. Surveillance Tailored to Purpose:

The core difference lies in the purpose of surveillance:

    • Business security aims to deter theft, monitor transactions, and enhance customer safety. For businesses such as retail stores for example, cash registers, entrances, and parking lots take precedence.
    • Residential security is driven by a desire to protect loved ones and property. It involves monitoring family spaces and valuable possessions.

Understanding these distinctions is the first step toward tailoring your security setup to meet the unique needs of your property, whether it’s your cherished home or your thriving business. Each setting demands a customized approach, ensuring that you’re well-equipped to address the challenges that come your way.

What areas of the property need security cameras?

CCTV surveillance must cover any vulnerable points[1] such as entry points (gates, doors, windows, driveways) and any other sensitive or high traffic areas. This can vary depending on what the property is used for – residential or commercial – and layout.  

Residential areas

Some examples of areas to monitor in a home are:

  • Front Door
  • Back Door
  • Driveway
  • Front yard
  • Back yard
  • Either sides of the house
  • Garage and/or driveway
  • Living room
  • Hallway
  • Child’s bedroom
  • Rooms with safes

Commercial areas

Common areas to monitor in a business are:

  • Primary entryways
  • Secondary entrances and exits
  • Parking lot, driveway
  • Customer areas like lobbies and receptions
  • Staff only areas
  • Cash registers
  • Seating areas
  • Restaurant kitchens

Striking the Budget-Security Balance

So, you’ve meticulously planned which nooks and crannies of your property deserve the vigilant gaze of security cameras. You’ve envisioned a robust security setup that leaves no corner unchecked. Yet, here comes the daunting reality check – your security budget may not effortlessly align with your security aspirations. Fear not; it’s time to embark on the delicate art of balancing budget with security requirements.

1. The Initial Investment:

  • Picture your security setup as an investment in peace of mind. The upfront cost can vary significantly based on your choice of equipment and installation needs.
  • Consider whether you lean toward higher quality security equipment that might entail a more substantial initial investment but promise durability and reliability. Or, are you swaying towards lower quality security equipment that’s easier on the wallet but may require more frequent replacement?
  • Take into account any installation fees associated with setting up your chosen system.

2. Ongoing Expenses:

Beyond the initial investment, there are ongoing costs to contemplate. These include:

  • Monthly service costs if you opt for professional monitoring services.
  • Maintenance costs to ensure your system runs smoothly.
  • Expenses associated with cloud storage or NVR storage, depending on your data retention needs.

3. Prioritizing the Essentials:

  • In the realm of budget-conscious security, prioritization is key. Begin by identifying the most critical areas that must be under surveillance. This might involve differentiating between areas like the front door, which is a security focal point, and less critical spaces like hallways.
  • Recognize that compromise is sometimes necessary. Perhaps the driveway camera isn’t as indispensable as the front door camera, or monitoring a customer in a waiting area takes precedence over the hallway.

Remember, finding the sweet spot between your budget and security needs requires thoughtful consideration. It’s a puzzle where each piece represents a choice between safeguarding and financial strain. By striking this balance, you can create a security setup that not only protects your property but also aligns harmoniously with your fiscal reality.

Overlapping monitoring zones

Sometimes with smart placing of cameras, you can monitor multiple areas from one camera, thus reducing the need for lots of cameras. For example, the driveway camera may be redundant with a front door camera in place, and a back door camera may eliminate the need for a back yard camera. Take a look at your house plans and work carefully with your CCTV system designer to see if you can combine the functions of multiple cameras into just one that is very conveniently placed. Make sure you avoid making any blind spots[2].


As you may have gathered, it is impossible to give a great recommendation for how many cameras your property needs without careful, personalised analysis of the property and your security needs. In general, residential properties get away with 2-6 cameras, and businesses can have as many as 16-64, but as every case is unique, you have to decide for yourself what is important to monitor and what isn’t.
