01
Detect a human
Set an intrusion zone and active hours. The camera analyses the scene and triggers the selected human rule, reducing unwanted alerts from animals and general motion.
02
Record the moment
The camera sends the event to your NVR. Timestamped recordings and event snapshots help you find the incident and review what happened before and after it.
03
Sound the warning
A configured human intrusion can activate a connected external siren or spoken warning through a supported camera output, helping discourage an intruder from proceeding.
04
Receive an alert
Get an intrusion notification on your mobile phone. Open the connected app to check the camera view and assess the event, even when you are away.
Every channel. Connected intelligence.
All Stanklin NVR channels support AI events from compatible connected cameras. Detection takes place in each camera; the NVR brings the events and recordings together. Combine human detection, timestamped evidence, an audible warning and a mobile alert for stronger active deterrence.
External siren operation requires a compatible camera output and connected siren or speaker. Mobile alerts require app setup and network connectivity. Configure detection zones, schedules and alarm actions for your installation. Detection accuracy varies with the scene and installation.
Wired reliability
Connect over Ethernet to your local network and a compatible NVR for continuous recording to an installed hard drive. Power the camera with an 802.3af PoE switch or injector, or a 12V DC supply. Local recording can continue without internet while the camera, network, and recorder remain powered.

No monthly fee
