The eTiger S3b-SV GSM + IP camera alarm system is a complete starter kit. The free-standing IP camera doesn't communicate with the alarm system. When the system detects something, it'll trigger the integrated alarm with a 100-decibel audio signal and you'll receive a notification via SMS message, a phone call, or the app on your smartphone (iOS and Android). You can then sign into the IP camera's app to
watch a live feed of what's happening, and even record the footage to store it in the cloud. You can configure up to 10 phone numbers that you want the system to notify in the event of a threat. You can switch the alarm on or off with the remote control, NFC tag, or the app on your smartphone (iOS and Android). The alarm system uses AC power and has backup batteries.
Note: this alarm system uses a SIM card (not a micro or nano SIM card), which isn't included by default.
