Intrusion and perimeter detection with smart alarms

Nara turns your existing IP cameras into smart alarms. It detects people, vehicles or animals in the zones and hours you set, including at gates and fences at night, and sends an alarm with images to the guard’s phone. Everything runs on-site, without internet.

Nara monitoring four warehouse cameras with smart alarms

[ 01 ]The problem

Sites need to know straight away when people or vehicles enter closed areas after hours, without a guard watching every screen.

How it works

Draw the zones and set the hours. Nara detects people, vehicles and animals in each zone and raises an alarm only for what you care about, with images sent to the guard’s phone. Events are saved so you can search them later, and the same cameras can also watch for fire and smoke.

Works with Nara’s built-in models. You set up the zones, rules and outputs.

[ 02 ]Variations

The same building blocks, applied a few ways.

01
After-hours intrusion
People, vehicles or animals in zones on a schedule raise an alarm with images to the guard’s phone.
02
Perimeter and gates at night
People detection at gates and fences in low light, processed locally without internet.
03
Smart event recording
Images and clips are saved only when events happen, in a searchable log.
04
Abandoned objects and asset removal
Alerts when an unattended object stays in a zone longer than a set time, or when a watched object leaves its position.
05
Cross-camera person tracking
Person re-identification follows a person across cameras and devices for investigations.

[ 03 ]Where it runs

Proof from real deployments.

Industrial and commercial sites, several deployments

Smart alarms that mitigate 5–10 million THB in potential stock losses

5–10 M THBof potential stock losses mitigated

FAQ

Questions, answered.

What results have customers seen?

One site security deployment mitigates 5–10 million THB of potential stock losses and saves 30,000 THB a month in guard costs.

Does it need an internet connection?

No. Nara runs on your own hardware on the local network, and images and results stay on-site. Eligible tiers also support offline licensing locked to the hardware.
