Spider Eye is the on-site scanning companion for Park Spider, the web-based parking management platform for property management companies, HOAs, and landlords. Point your phone at a license plate and get an instant verdict. Spider Eye reads plates with your camera and checks them against the vehicle list your organization maintains in the Park Spider dashboard, so anyone on your team can patrol a lot without a clipboard or a printed list. WHAT IT DOES - Scans plates live through the camera as you walk the lot - Instantly shows whether a vehicle is registered, has a guest pass, or is unknown - Uses state of the art machine learning & computer vision for super fast detection - Keeps each property's vehicle list synced to your phone - Records scans to your organization's history in the dashboard BUILT FOR TEAMS Spider Eye is for staff at organizations that already manage parking with Park Spider. It requires an active Park Spider organization account to sign in; it is not a standalone app. Properties, vehicle lists, and team members are all managed in the web dashboard at parkspider.com.
