    The Critical Differences

    No Towers Required

    Traditional systems require expensive repeaters and FCC licensing. Sentinel uses existing nationwide LTE/5G networks, giving you instant deployment without the capital expenditure.

    Unlimited Range

    If you can get a cell signal or Wi-Fi, you can talk. Your team in New York can talk to your team in Los Angeles as if they were in the same room.

    Advanced Intelligence

    Voice is just the beginning. Sentinel includes real-time GPS tracking, emergency alerts, and a browser-based dispatch console that traditional systems simply can't match.
