EL Tech vs SidecarBridge

EL Tech helps airport maintenance personnel, technicians, and field engineers monitor ASOS, AWOS, and NEXRAD systems. Review surface observations, maintenance indicators, NEXRAD station telemetry, alarms, and available historical data. Keep site details, photos, issues, and imported maps together. The site map focuses on equipment and saved locations, with an optional Mammatus WX link for weather maps.

SidecarBridge turns your iPhone or iPad into a private local viewer and remote-control surface for your Mac. Pair once with the companion Mac app using its temporary 16-digit code or QR code. Reconnect with a saved trusted Mac over your local network or a nearby peer-to-peer link. FEATURES • Encrypted local sessions and remembered trusted devices • Hardware-encoded Mac screen streaming with quality and frame-rate controls • Touch and trackpad gestures for clicking, dragging and scrolling • On-screen controls and physical keyboard support, including Chinese/English input • Picture in Picture viewing where supported • A dedicated Files & transfers tab with connection controls and visible progress • Browse accessible Mac folders, see file/storage information, calculate folder sizes and download selected files or folders • Send files and whole folders to your Mac; folder transfers use ZIP archives PRIVACY AND REQUIREMENTS Both devices need SidecarBridge. The Mac needs Screen Recording permission to share its display and Accessibility/event-posting permission for remote input. File access remains subject to macOS privacy permissions and sandbox grants. Sessions stay local or nearby; no cloud relay or user account is required. SidecarBridge mirrors the Mac's main display, not a native extended display, and does not bypass Apple's security protections. This release focuses on Mac, iPhone and iPad.
