Sentra AI turns your existing security cameras into a real-time alert channel you can trust. Whether you are watching over your home, your shop, or a business site, you get told when something actually happens. Most camera systems flood you with motion alerts, and almost none of them matter. Sentra AI verifies detections before they reach you, so the notifications you get represent real events, not wind, shadows, or passing headlights. WHAT YOU GET Real-time verified alerts A push notification the moment a verified event is detected on one of your cameras, with a preview image and a short description, so you know what happened before you even open the app. Full event details Open any alert to see the captured image, which camera it came from, the exact time, and what was detected. Built-in media viewer View event images and clips full screen inside the app. Camera and alert control Choose which cameras you watch, which detection types matter to you, and set schedules or mute windows so you are not alerted when you do not want to be. Multiple users per account Add several people to one account so alerts reach everyone who needs to see them: family members, staff, or whoever is on call. WhatsApp alerts Optionally link a phone number to receive alerts on WhatsApp as well. Six languages with full right-to-left support English, Hebrew, German, Spanish, French, and Portuguese. GETTING STARTED Sentra AI works with connected NVR and camera systems. An account is required. Contact us through the support link on this page to find out about availability for your setup.
