Our take: Worth considering if insurance compliance or high-security safes are specifically part of your project, but the one detailed negative review is worth weighing given how few total reviews back up the rating. Ask about current support response times before committing.

How we score

Every number on this page is computed from public Google data on the date shown, not from opinion or payment. Rating is the provider’s live Google star average. Review volume is how many customers have rated them, ranked against other Hong Kong security providers. Confidence weighs the rating by that volume, so a 5.0 across over a hundred reviews carries more weight than the same score on a handful. Recency reflects how recently customers are still leaving reviews. No business can pay to change these numbers.

How much do security systems cost in Hong Kong? (2026)

Pricing depends heavily on scope: a residential alarm and camera setup costs far less than a commercial access control system or ongoing manned guarding contract. Insurance-grade systems and high-security safes add further cost on top of standard installs.

Serving all of Hong Kong

The providers above cover Hong Kong Island, Kowloon and the New Territories, with offices in Kwun Tong, Sheung Wan, Cheung Sha Wan and Hung Hom. Searching for security systems near me? Every listing below shows a live phone number and directions so you can reach the closest office.

What to ask before you hire a security provider

Do I need installed hardware, on-site guards, or both?
Is the quote based on a site survey, or a general estimate?
What is the warranty or support response time on installed equipment?
Are your guards licensed by the SGSIA?
Does the system meet any specific insurance compliance requirements I have?

Frequently asked questions

How did you choose these security providers?

We started from security system providers in Hong Kong with a public Google presence, then ranked by rating, review volume, consistency and recency. See How we score above.

Are these rankings paid?

No. Rankings come from the public Google data in the scorecard. A business can pay to be a Featured Partner, which adds a badge and top placement, but that never changes another business’s score or position on the underlying data.

How often is this updated?

The data carries a verified date (August 2026 on this page). We refresh listings periodically so ratings and review counts stay current.

Which of these providers offers guards rather than installed systems?

MC Security (MCS) focuses specifically on manned guarding and executive protection. Securitas and Ensec offer both guarding and installed hardware, while Gammon focuses on installed systems and secure safes.

How much do security systems cost in Hong Kong?

Costs vary too widely by scope and property type to quote a general range responsibly. Ask each provider for a written, itemized quote based on a site assessment.

The bottom line

Securitas is the safe default for a business wanting both guards and installed systems from one established provider, while Ensec and Gammon are strong specialist picks for hardware-only installs. Whoever you choose, confirm whether your need is guarding, installed systems, or both before you get a quote.
