Security system installation & repair

Updated 4 November 2026

Installing a security system in Hong Kong usually starts from about HK$1,500 for a basic alarm package in a small flat, and a 4K CCTV kit with recorder starts from HK$4,299. These are approximate prices from sellers' websites, November 2026. Describe your site and the work in a request on BlaBlaPrice to get current offers for your home or shop.

Installer licence and what to check

In Hong Kong, installing, maintaining or repairing security devices, and designing security systems, is regulated, and a company doing this work needs a Security Company Licence. Before you agree, ask for the company's licence number and check it against the government's published list of licensed security companies. A company that cannot give you a number should not be your first choice.

Season and the humid summer

Winter runs from December to February. Summer, June to August, is hot and humid, which is hard on outdoor cameras and cables, so say in your request whether the cameras go inside or outside. If they must sit outdoors, ask the technician for weatherproof housing and cable protection.

How the work is priced and delivered

Prices are usually quoted per camera or per system, and the price normally includes the device, the cable and the set-up. Building work is often a separate charge: ask whether drilling and making good walls after installation is included, because standard installation agreements list building repair work as a separate payment. The service covers Central, Kowloon, Sha Tin, Tsuen Wan and Tuen Mun, and the technician needs the site address, access times and the flat size in square metres.

What to write in your request

Name the system you want (alarm, CCTV, access control or a combination) and the number of cameras or doors. Say whether you need a monitored alarm, and whether this is a new installation or a repair of an existing system. Give the site address, the size in square metres, and your budget.

On BlaBlaPrice you describe the job in your own words in a chat, and the AI asks about missing details such as the number of cameras and the site. It then looks through local sellers' websites and price lists and shows the prices and businesses it found. Sellers registered on BlaBlaPrice reply in the chat with their own offer, price and terms. Your contact details stay hidden until you choose to share them. If the job includes wiring, see electrical installation, or start from the home page.
