Security systems: types and why they matter
From a smart lock on an apartment door to access control systems in companies and factories. Learn the differences between security systems, why each matters, and how to choose the right one for your site.
Why does a security system matter?
A security system does more than prevent theft; it gives you control over who enters your premises and when, instant alerts if something happens, and a record you can refer back to when needed.
In companies and factories, security systems organize employee and visitor access, record attendance accurately, and reduce reliance on keys that can be copied or lost. In homes and shops they give you peace of mind while you are away.

How to choose the right security system?
Questions to help define your needs.
- What do you want to protect: access, merchandise, or the premises while you are away?
- How many doors or entrances do you need to control?
- How many people will use the system, and do they need different permissions?
- Do you need attendance or door-opening logs?
- Is there power and an internet point near the installation location?
- Do you want the system to expand later with more branches or staff?
Frequently asked questions
What is the difference between access control and a smart lock?
Access control is a system that manages one or more doors with permissions per person, usually with an electric lock and exit button, while a smart lock is a standalone lock on the door itself, better suited to apartments and small offices.
Can I link fingerprint attendance with access control?
Yes, some devices do both: they open the door and record attendance at the same time.
Does the alarm system send alerts to my phone?
Yes, smart alarm systems send alerts through the app or by message and also sound a siren on site.
Do the systems keep working during a power cut?
It depends on the system; many are installed with a backup battery or UPS. We determine this with you during the site survey.
Do you install for companies?
Yes, we provide site surveys, quotations, installation, programming and training for your team.
