Why Choose
Nexo Security?
Thinking about installing your own smart alarm and intruder detection system?
If you’re confident with technology, wiring, and system setup, you may be able to install it yourself to save costs.

Below is a detailed step-by-step guide to help you decide and, if you choose the DIY route, get started the right way.
Good planning ensures your alarm system offers the right protection for your property. Before buying equipment, ask yourself:

Common reasons include deterring intruders, protecting valuable assets, or getting real-time alerts in case of a break-in.

How large is my property and what areas need coverage?
This will determine the number and placement of sensors.
Do I need 24/7 monitoring?
Decide if you want a monitored service or self-managed alerts through your phone.
What is my budget?
Smart alarm systems vary from affordable DIY kits to fully integrated, professionally monitored setups.

For the highest reliability, many property owners choose a professional installation and monitoring service, ensuring every sensor, setting, and alert is optimized for safety.
