Frequently asked questions

How does a wireless alarm system work?

Sensors on doors, windows and rooms send a radio signal to the alarm panel. The panel sounds a loud siren and, on Wi-Fi or GSM models, sends phone alerts.

Can I add more sensors later?

Yes. Wireless sensors, remotes and panic buttons from the same frequency can be paired with the panel. The number of zones is listed in the product details.

Does it work without internet?

GSM models use a SIM card to call or send SMS even without Wi-Fi. Wi-Fi models need working internet for app alerts.

Do prices include GST?

Yes. Yes. All prices are inclusive of GST, and NavKar Systems delivers across India.

Is technical support available?

Yes. Free technical support is available for installation and setup.
