Your home is your biggest investment, and your family is everything to you. Protecting everything that is yours, is top priority and it requires a good security system to make sure that you and your belongings are safe. The security system business has been booming over the years, with more and more homeowners realizing that it is one of the best way to help prevent break-ins and robberies. Today you will find a wide range of security systems, from the basic home security system, to big, more elaborate security systems that can do everything imaginable to protect your home. Choosing the right company and system is important for your family’s safety, the security of your personal belongings, and your peace of mind. You also want the best security you can get for a price that you can afford. So how do you know which systems are the best and which one is right for you? Read on to learn about the top ten security systems on the market today.

CCTV and privacy

If you’re thinking of getting a home CCTV system for the outside of your property, you must comply with privacy laws. This means making sure that your cameras aren’t pointed at public spaces, or other people’s houses or gardens. It’s a good idea to discuss any CCTV plans with your neighbours first – some Which? members told us that they share a system with their neighbours, which might be one way to cut costs.

Home CCTV features

Storing CCTV images Most home systems use a PC hard drive or standalone digital video recorder (DVR). The main advantage of PC-connected systems is that they often come with software to view the images. Some DVR-based systems also have this facility.  Make sure your system allows you to store images in a widely used format, such as Mpeg. Otherwise there may be problems if images need to be downloaded and viewed on other systems, such as those used by the police. In addition, make sure that if you get a camera that can record high-quality images, the PC or DVR is able to record them. Remote access Some home CCTV systems, such as IP ones, let you check images over the internet using a PC or smartphone. Other options include email or text notifications when cameras are activated. Night vision Monochrome (black and white) CCTV cameras tend to be the most effective in low light, particularly when used with integral infrared illumination – a feature found on some cameras. It’s possible to use CCTV cameras that will film in colour during the day and switch to monochrome when it gets dark. Motion detection Some CCTV cameras have a sensor that turns them on when they detect movement. This can be handy if you want to reduce the amount of footage you’re storing.

CCTV footage resolution

CCTV footage resolution

CCTV camera resolution is measured in lines – the higher this is, the sharper the image will be.  Image quality is also linked to the size and type of chip the camera uses. Generally speaking, smaller CMOS chips are lower quality than larger CCD ones, such as 1/4″ and 1/3″.  Cameras with tiny chips also tend to be able to pick up less light, and therefore produce lower-quality images in low light. The light sensitively is measured in lux, which can range from 130,000 to 0.001 lux. The lower the lux, the better the camera will be at recording when there isn’t a lot of light. You’ll need high-quality images – sufficiently clear for someone to be identified – if CCTV footage is to be used as evidence in court. However, for the best detail, you need a high resolution – this tends to make the camera more expensive, and can take up a lot of storage space. Also make sure the date and time used to ‘tag’ images are set accurately.

Home CC Camera

However, it’s not for everyone – only 10% of the 4,353 Which? members* we surveyed in September 2017 have home CCTV or a wireless camera. You can buy cameras on their own, or as part of a whole security package. Costs range from around £20 for one wired camera with a night-vision range of 5 metres, to around £450 for a vandal-proof camera.  You will need to buy some equipment to accompany the camera, depending on what type you choose, such as connectors and a digital video recorder (DVR) to store and view the footage. You can also buy dummy cameras for around £10.  CCTV is just one line of defence against crime, and works best when combined with other measures, such as a burglar alarm, door and window locks, gravel around your property, and security lights. If you’re thinking about getting a burglar alarm, visit our pages on burglar alarm types and the costs of installation to find out more – we’ve spoken to a number of installers and found their advice, and what they offer for the same price, varies greatly. You can also discover the top-rated burglar alarm companies, according to our survey of more than 3,228 burglar alarm owners.

How home CCTV systems work

hese are the most common and cheapest type of camera, where a wire connects directly from the camera to the monitor. The downside is that the wires, including extension cables and connectors, can be difficult to install. Wireless home CCTV systems With this type of system, cameras transmit images to your computer, tablet or mobile phone, using analogue or digital technology. Many smart security cameras link to an app that you can use to monitor your home while you’re out and about. Digital cameras are generally higher quality, but more expensive. Wireless systems can suffer interference from devices such as routers, cordless phones and microwaves, and can be blocked by heavy masonry or metal objects. Your filming may also be interrupted if your internet connection is lost.

IP CCTV system 

These are cameras that use your network or internet portal (IP) to send images to your computer’s router, allowing you to access the footage over the internet from remote locations.

Outdoor home CCTV cameras

If you’re using CCTV cameras outside, make sure they’re weatherproof and have the recommended IP rating of 66. Wireless cameras are available, but you’ll still have to run a cable to a power source. Position cameras where they can’t be tampered with, but are accessible for maintenance and cleaning. You can buy vandal-proof cameras, but these tend to cost more.

Why is dehumidification important for your home?

Humidity, all that muggy air. It can make you uncomfortable on those warm summer days and nights which isn’t much fun. In New Zealand, we experience humid weather, even in an air-conditioned home, there can be a rise in humidity levels. This isn’t good, for so many reasons.

Humidity, all that muggy air. It can make you uncomfortable on those warm summer days and nights which isn’t much fun. In New Zealand, we experience humid weather, even in an air-conditioned home, there can be a rise in humidity levels. This isn’t good, for so many reasons.

Aside from the lack of comfort, a rise in excess air moisture can actually lead to building and property damage, can have dramatic and ongoing health repercussions for your family, and can have an impact on your hip pocket too, as energy bills increase due to running your heat pump at a higher temperature more often to counter the effects.

The recommended humidity for indoor environments is between 30% to 50% relative humidity (this simply means the amount of water vapour the air contains compared to the maximum amount it could hold at any given temperature). Levels any higher than this are unhealthy and inefficient.

Luckily, indoor humidity can be lowered through dehumidification (or increased in a dry winter through humidification). There are also times of the year when your indoor environment doesn’t necessarily need heating or cooling to be in a comfortable range, but may still need humidity control.

Some clever ducted and split system heat pump units offer the latest in cutting edge technology, which means they not only provide efficient cooling and heating for your home, but can humidify, dehumidify, ventilate and purify the air!

With some systems, you can activate the dehumidification of your home environment with the single touch of a button on a user-friendly remote control. So if the humidity has drained your energy temporarily and you can’t even get off the lounge, it doesn’t get any easier than that!

Let’s take a topline look at some of the problems high humidity levels can cause to your health, your comfort and your home:

  • A moist home becomes a welcome breeding ground for allergens such as dust mites, mould and mildew
  • you could therefore be susceptible to a range of symptoms of allergies or asthma
  • your body can’t cool down effectively because the humidity doesn’t allow your sweat to evaporate quickly. (This is why a humid day feels so much worse than any other day at the same temperature)
  • small black spots (mould spores) are prone to grow on the walls or in areas with high humidity, such as the bathtub or shower
  • mould can also multiply unchecked on clothing or furniture
  • musty or mildew smells linger in an excessively humid climate
  • water stains may appear on the walls or ceilings of your home
  • you may see frequent condensation on the windows in certain areas of your home
  • you’ll experience higher than usual humidity in rooms with poor ventilation or no ventilation (especially areas like bathrooms)

The benefits of dehumidification
With these health and environmental concerns, it’s easy to see that the benefits of maintaining proper humidity control in your indoor environment cover so many areas… from personal comfort to the actual health of your family. Here’s why removing some of the excess moisture in the air through dehumidification is so important when heat pump your home. Improved comfort levels
It seems obvious to say, but dehumidification reduces humidity levels, which means levels of comfort are immediately increased. Dehumidification will help you feel more comfortable without dramatically lowering the thermostat settings on your heat pump (which means it’s more energy efficient too). You’ll immediately feel less clammy, less sweaty and less tired, as the air will feel less heavy. A healthy home
Dehumidification helps to keep indoor air at a reasonable humidity level, which helps to keep every member of the family healthy. In a nutshell, it helps you all breathe easier. Common allergy triggers, such as dust mites, mould and mildew thrive in an excessively humid environment. So if you or any family member suffers from allergies or asthma, high humidity can severely aggravate these symptoms. In fact, these allergens can even make a normally healthy person ill. Some common reactions to these moisture-loving allergens include:

  • a stuffy nose
  • itchy, watery eyes
  • sneezing, wheezing, difficulty breathing
  • skin rashes
  • a diminished immune system
  • diminished resistance to respiratory allergies and infections

A better indoor ‘smell’
Indoor air that is free from damp, mould and mildew smells fresh and inviting. Dehumidification helps reduce odours that can accompany mould and mildew in your home, thus getting rid of that “musty” smell.

Protected clothes and fabrics
Excess moisture or humidity in your home increases the potential to develop mould on your clothing, furniture, bedlinen, towels, curtains and any other fabrics. Dehumidification can alleviate this problem.

Protected Property
Dehumidification can help to protect your property too – so you won’t find signs of rust or corrosion on things like computer equipment, electronics and tools.

Everything is fresher!
A less humid environment in your home means clothing will dry faster, and even breads and cereals will remain fresh longer without getting stale.

Less cleaning time
Dehumidification helps to reduce dust in your home. Less dust means you won’t have to clean as often.

Lower energy costs
Dehumidification means lower energy costs because it helps your heat pump run more efficiently. High humidity makes it seem warmer than the actual room temperature, so you may set your thermostat lower to cool your home off more. However, with the flick of switch to a dehumidification setting, you’ll be able to set your thermostat at a higher temperature, thus reducing energy usage and your bills. Also, this can have an energy-efficient knock-on effect – since you won’t need to lower the temperature as much, your heat pump won’t be constantly running.
