GSM Home Burglar Alarm with Door Sensor, App Control, Camera Support & High Sound

A GSM-enabled home security alarm with door sensor and app control, designed to deliver loud alerts and remote monitoring. Notification behavior: if external power fails or the built-in battery is low, the system sends both APP push notifications and SMS; when external power is restored it sends an APP push; tamper detection triggers an SMS alert. Phone alerts: supports 5 preset groups of alarm phone numbers — for each group you can independently enable/disable SMS and dialing notifications. Scheduling and delays: program timed arming/disarming for daily automation, and set both arm delay and alarm delay to suit your needs. Camera integration: works with a camera so that on intrusion you can immediately view the situation remotely, speak through the system and help scare away intruders.
