It’s not uncommon to see CCTV cameras situated on every corner of every building in commercial areas. As one of the easiest systems to set up, and one of the most cost-effective security systems, CCTV is used by almost every business to protect their property, and nowadays, they’re becoming a more frequent occurrence on homes too, with our team alone installing domestic CCTV 4-5 times a week. CCTV can dramatically increase the security of your property and keep your family protected, so we’ve put together our top 5 benefits of installing CCTV in your home to help give you incentive to install CCTV to your premises: 1. When evaluating your insurance policy, the security of your property plays a huge impact on the amount of money you will pay, so by taking steps to make your property more secure and reduce the likelihood of your property being damaged or vandalised, you are in turn reducing the likelihood of you making a claim, allowing your insurance provider to reduce your policy costs. This means that thieves are much less likely to target your home, helping keep your belongings secure and increasing the safety of your family. Another good use of CCTV is to use as a peephole for homes that are without them – if you receive a visitor late at night and are unsure who it could be, you can identify the visitor without having to answer the door.
