If you break it down into types (not brands), the top three are:
1. Integrated security systems
Everything (cameras, alarms, access control) is connected into one platform.
2. Cloud-based systems
You can manage security remotely, store footage off-site, and scale easily as your business grows.
3. Hybrid systems
A mix of on-site hardware (for reliability) and cloud features (for flexibility and remote access).
These three stand out because they balance control, scalability, and real-time visibility—which are the most important factors for businesses.
