CCTV Buying Guide for Home Security

21

There can be much confusion when it comes to buying a CCTV system (Closed-Circuit Television) for your home. What you need to remember is that the system needs to meet your specific requirements at a budget that you can afford. Below we explain the different types of systems that are available for your home security, and what you need to look out for when choosing the right home system for you.

Wired systems

A wired home security system is the most popular and cheapest option. This is when a wire connects the monitor to the camera. The downside to this option is that the wires can be troublesome to install and you may be left with trailing wires.

Wireless systems

This system requires the use of a tablet, computer or smartphone to be able to receive the images. If you use a smart security home system, then there are usually many apps available that will make the set up incredibly easy. It also means that you can monitor your home when away from your property. The downside with this type of system is that it can be more expensive and the signal can be blocked by heavy metals within your home. The signal can also be poor and face interruptions.

Internet security

This type of home security system works with your internet. It sends images of your home to your computer. In doing so, you will be able to access these images from any location. So, this is a great system for when you are away on holiday, or are away from home for extended periods of time.

Outdoor cameras

If you are wanting a CCTV system for outside of the home, then you need to make sure that it is completely weatherproof. This is when the IP rating comes into play. IP stands for International Protection, and ideally the camera should have a rating of at least 66. You can choose between wired and wireless systems for outdoor use, but they will still need to be connected to a power source. Additionally, you can purchase vandal proof cameras, but these tend to cost a lot more.

Resolution

When buying any home security system, you need to carefully consider the TVL or TV resolution. This very much depends upon how much you can spend and what quality of image you require. The average camera has a TVL of between 350 to 550 TVL, with the highest being 700 TVL. However, TVL is not the only factor responsible for a good quality image, so too is the sensor and monitor.

Night vision

If you are wishing to only use your camera during the night, then a monochrome camera is your best option as these operate best in low light situations. When this type of camera is coupled with infrared then you get an even better quality of image. There are also some cameras available that will film in colour during daylight hours and then start filming in monochrome when the light levels drop, so this way you get the best of both worlds.

Motion detection

If you want an energy saving camera, and one that will not quickly fill the hard drive of your computer and draining much needed storage space, then a motion sensor is a good idea. This works by only recording when there is movement, so best used when you want to monitor your home for security reasons, rather than aesthetics.

The lens

The lens is responsible for focus and clarity. This therefore will result in a clear image of an intruder’s face or a readable registration car plate. Therefore, it is always best to get the best quality lens that you can afford. An optical lens is also preferable to a digital lens as it works best in low light and can give a more detailed image.
