CCTV, which stands for “Closed-Circuit Television,” is a system that involves cameras, screens, and recorders working together to keep an eye on things and enhance the safety in your home.

Once thought of as a regular fixture found only in commercial premises and areas, installing CCTV is becoming an increasingly popular security option for homeowners. It is an unfortunate truth that burglaries are a fact of life. And you most likely know of a friend or family member whose house has been broken into or had their car damaged within the last three months.

So, it stands to reason if you are somebody who:

  • wants to clear your mind about security;
  • is looking for reliable ways to deter intruders and vandals;
  • thinks about boosting the property value and getting an insurance discount;
  • wonders what the pros and cons of CCTV installation are.

Armed with a coffee and enthusiasm, read further to find out the advantages and disadvantages of CCTV systems and their best uses. Rather than taking hours, solving your dilemmas will take minutes!

But first: Why is there so much CCTV installed in the UK? 

Did you know that CCTV cameras in the UK are a big chunk of the total CCTV installations in the world? According to the surveillance camera statistics, the total number of CCTV cameras in the UK are 4-5.9 million (>627,000 in London) overall, ranking the Britons as one of the most-watched nations in the world. (Sigh!) 

Guess why! Well, the CCTV network in the UK grows because you won’t need to fork out a fortune to get your home equipped with a CCTV set. Advances in technology have made them inexpensive to manufacture. It is a low-cost investment for the peace of mind you get by being able to keep an eye on your children, pets and property whenever you like and wherever you are.  

And unlike the other traditional security systems, with CCTVs, you rely on comprehensive monitoring of your home and an unbiased source of truth in case of burglary or vandalism.

Also some people wonder “Do you need a licence for home CCTV?” The answer is no, you don’t need a licence to install a home CCTV.

What are the advantages and disadvantages of installing CCTV cameras?

What are advantages of CCTV?

  • Dissuade thieves. Flip your perspective if you think you can fool a burglar with a fake camera, a TV or a lamp turned on at night, while you are away. Most burglars are well trained and will be dissuaded from targeting your home if only they see a *real* surveillance camera at the entrance. In fact, houses with CCTV are 90% less likely to be broken into than those homes which do not own such a system. 
  • Reduced insurance premium. Cameras are one of the many security steps that you can take to make your property safer and to also reduce the chance of your property being damaged or vandalised. This, in turn, means that you are less likely to make a claim, which is something that your insurance provider will be more than happy to hear. That said, the level of security of your property can be a major influence on the amount of money you will pay the company. 
  • CCTV systems help in prosecution. Should the worst happen and your property gets burgled, vandalised or damaged, statistics show that solving ⅔ of the police’s jobs becomes much easier if you can hand over some CCTV footage. Provided that criminal activity happened close to your cameras and the images are clear enough for police to identify the culprits and bring them to justice, you could catch anything from a number plate to the faces of those who committed the crime. 
  • Remote monitoring. Modern CCTV home systems allow you to keep an eye on your house and the surrounding area from anywhere in the world, so long as you have a good internet connection. By installing cameras and setting up the option to receive notifications, you can watch live footage or access recorded video via your tablet, laptop or mobile phone. 
  • Peace of mind. Apart from the advantages of having a CCTV system installed, it goes a long way in putting your mind at rest whether you are relaxing on your sofa or making a trip to the supermarket. You can’t be in two places at once, but with CCTV installation, you will be able to check what is going on in and around your home. 

What are the negatives to CCTV?

  • You must comply with privacy law. Even if you would like to help in curbing the foul play and antisocial behaviour in the neighbourhood, private CCTV should only be used to ensure the security of the property it is installed on. Use the boundary of your property or garden as a guideline. Otherwise, if your security system captures anything outside of that, it could be considered as intrusive. 
  • Cyber attacks are a real hazard (if attackers are motivated). Forgot to change the default password credentials and update the firmware while in a rush? Then, one day you may discover that somebody hacked your internet-connected CCTV camera and has access to your entire internet life and possessions. But taking actions, such as selecting cameras with advanced encryption or regular updating your router password, is a surefire way to promote your security. 
  • CCTVs can be stolen, disarmed, vandalised, or have blind spots. Wireless cameras, for instance, are comparatively easy to disconnect and disarmed if head-to-toe in black attackers are determined to rob your house. If you want to feel truly safe at home, invest in a tamper detection so you can prevent physical attacks against your camera. To select a camera with 360-degree rotate feature can address the blind spot culprits successfully.
  • CCTV can reduce crime but can’t stop it. So often, people think that CCTV cameras are their first line of defense. But we often see crime, burglaries, or vandalism happen, right? The truth is, you need more layers of security protection to get your home fully protected, like installing secure locks. To be honest, security cameras alone are more about property monitoring and crime-solving rather than a crime-reduction tool, but they can be the single missing part of your home security system.

Cost of installing CCTV camera at home? And is CCTV price your biggest drawback or benefit?

As with many buying decisions, installing a CCTV system comes down to your security needs, and your budget. Unfortunately, on price, CCTVs are a big dilemma. 

The cost of the CCTV system may stretch depending on factors, such as the size of your home, the number of cameras needed, the unit types, smart home automation, security sensors, control panels… and the list goes on… 

  • A low-end 4-camera system can be found for around £159 to £199;
  • A medium-end 4-camera system can cost around £1,000 to £1,500;
  • A high-end 4-camera system can cost around £1,159 to £1,700.

For the installation costs, it can vary depending on the complexity of the system and the location. However, a good rule of thumb is to use a baseline of £400 for a budget, two-camera system and add £100 – £125 for each camera installed. So, for a 4-camera system, the installation cost would be approximately £600 – £800. Please note that these are estimates and the actual cost may vary. It’s always a good idea to get a quote from a local professional for an accurate estimate.

It’s also worth asking “Does home CCTV use a lot of electricity?”. Well, CCTV cameras at home typically do not consume a lot of electricity. The power consumption of a CCTV camera depends on the model and its specifications. Most CCTV cameras are rated between 2 watts to 10 watts. If a 5 watt CCTV camera runs for 24 hours in a day, it will consume around 3.6 kWh of electricity in a month.

In addition to the camera, you might use a DVR/NVR depending on your requirement. The wattage of a DVR/NVR is between 10 watts to 50 watts. So, if your CCTV surveillance system is running 24/7, it will cost you around £4 for a month.

To seek expert opinion from a CCTV engineer is a worthy investment as the more $ ≠ better stuff. The right choice totally depends on your needs.

The price for CCTV installation by a Fantastic Services CCTV engineer starts from £107 defined after an on-site survey. You can save yourself part of the CCTV installation labour costs and on future home maintenance services by choosing to become a Fantastic Club member.

Now, how do you feel? Do the positives prevail the negatives? If so, keep on reading!

An honest look at the pros and cons of CCTV camera types

Wireless CCTV cameras

Overview and ideal Wi-Fi CCTV use

With easy-peasy Wi-Fi CCTV systems, you will never miss a movement in and around your property. All you need to do is to attach your new security cameras to a power source and your Wi-Fi network. And voilà, burglars will think twice before trying to enter your home.

The best part? Wireless security cameras are wall-friendly and perfect problem-solvers for those who want to avoid the drilling mishaps from running wiring all over the property (such as tenants and temporary business establishments). Likewise, you may find them the best choice if you live in a small urban dwelling with an adequate Wi-Fi network, or you are on a budget. 

Wireless security camera pros:

  • You can record a full month if you use an SD memory;
  • Hassle-free installation, user-friendly interface, and discrete appearance;
  • No worries about hiding the wires;
  • Can be easily repositioned;
  • Reduced installation time and cost;
  • Hi-tech features and connectivity possibilities are endless;

Wireless security camera cons:

  • Wi-Fi cameras still require a power source;
  • You need a powerful router to enjoy a sound security system;
  • Cameras might become a doorway to unauthorised access if Wi-Fi encryption is not set;
  • A clear line-of-sight between the security device and the receiver is a must;
  • Frequent change of batteries is needed;

Wired CCTV cameras

Overview and ideal wired CCTV use

Plenty of concerns come up with spotty wi-fi coverage and dropped connection, particularly if you own a large property or there’s another powerful Wi-Fi network affecting your signal. In this situation, your better option is a wired CCTV system because they rely on a stable cable connection to both the router and recorder. As mentioned above, wiring is messy and disruptive to install, so typically it works best for homeowners running into a new renovation project.

Are you looking for a better option? The Power over Ethernet (PoE)-enabled devices might be the best format for your home as you won’t need to run extra power cables. This means you can easily add, reposition, change, or temporarily deploy security cameras. These types, of course, are easier to DIY and placed at the front door or in the garden.

Hard-wired security camera pros:

  • Rare signal drops unless there’s a system failure;
  • Lower risk of hacking;

Hard-wired security camera cons:

  • Lots of configuration = prolonged set-up time;
  • Extra units to the system mean extra cables to be run;
  • The system is not portable;
  • Less saving capacity for video footage.

Analogue cameras 

Overview and ideal analogue CCTV use

Analogue security camera pros:

  • Good performance in low-light conditions;
  • Lower bandwidth requirements;
  • Variety of camera models with all the features you need at an affordable price.

Analogue security camera cons:

  • Running multiple cables and wires means complicated set-up;
  • Reduced cable range (<1500 feet) and positioning limitations;
  • No encryption and no audio recording;
  • You get a blurred view if you want to enlarge the image;
  • Narrow field of view (FoV) so you may need more cameras to install.
