Local rules and what to check

Hong Kong's Noise Control Ordinance (Cap. 400) makes the person who controls an intruder alarm system responsible for how it is operated, so the owner or manager of the premises should control the siren. Ask the installer to test and commission the system against the government's minimum testing requirements for burglar alarm systems, which are set out in a published testing and commissioning procedure. Check the warranty in writing before you buy.

Season and installation timing

Summer in Hong Kong runs from June to August and winter from December to February. November falls between the two, so an installation now is finished before the winter months. Outdoor sirens and detectors face the summer weather, so check that outdoor parts are rated for it.

Delivery, installation and units

Kits are delivered between Central, Kowloon, Sha Tin, Tsuen Wan and Tuen Mun. Ask whether installation is included in the kit price. Give the premises area in square metres, sensor range in metres, and the siren's loudness in decibels (dB). Many listings sell kits by number of zones, so state how many doors and windows need sensors.

What to write in your request

Give the district, the premises area in square metres and the number of rooms or floors. Say whether you want a wired or wireless system, how many sensors you need, whether you want a monitored alarm, and who will install it. Add your budget so sellers quote a suitable kit the first time.

BlaBlaPrice is free for buyers. Describe the premises in your own words in the chat, and add a photo if it helps. The AI asks for any missing details, then looks through sellers' websites and price lists in Hong Kong and shows the prices and businesses it found. Sellers registered on BlaBlaPrice receive your request and reply in the chat with their own offer, price and terms, while your contacts stay hidden.
