MOBILELOCK Indoor Motion Detector Combo Kit $700 The DEWALT DS510K MOBILELOCK indoor motion detector kit includes the base unit--a GPS locator with anti-theft alarm (DS500)--along with a motion detector that triggers the alarm if movement is detected up to 50 feet away from the unit. The MOBILELOCK™ product is a stand alone, portable, wireless locating and alarm system that is easily mounted to equipment using integrated heavy-duty magnets or fastening the unit into place using screws. Unlike other mobile asset protection systems that use radio frequency to locate stolen assets, MOBILELOCK™ features a GPS locator that can help users find stolen or lost assets in real time. DeWalt Mobilelock GPS Recovers Stolen Assets! GPS Tracking Catches Dumb Stupid Robber Online Tracking Service Features: Unlimited Access to monitoring and reporting features Multi User access with unique user name and password Multiple Geo Fences set by street address or Lat-Long and Radius Automatic Alerts by e-mail or Cell phone Text Locations on demand at the click of a mouse Schedule management of automatic locates Auto Tracking via scheduled location pings down to every 5 minutes Reporting of all activity for power full analysis Google Earth integration for satellite photos Great service plan options with NO long term commitment: One Month Tracking Plan 5 Locates Per Month $19.95 Per Month .49¢ Extra After First Month How does it work? The four sensors built into the MOBILELOCK unit, tamper sensor, door contact sensor, vibration sensor and temperature sensor, can be programmed individually through a phone or the MOBILELOCK™ website to monitor the mobile asset. If an intruder tries to enter a secured area, disturb a piece of protected equipment, or remove the unit from the asset, the alarm activates and a signal is sent over the cellular network. If the MOBILELOCK™ protected asset is disturbed, the alarm is triggered and the user receives a phone call, text message or email notifying them that there has been a security breach. The user can log onto the MOBILELOCK™ website, enter their personal pass code and then access street maps or satellite imagery showing the approximate location of the MOBILELOCK™ unit. This enables users to quickly recover stolen or lost assets. Great service plan options with NO long term commitment: Emergency Locate on demand for asset recovery - Request a location online only when you need one. Recover stolen goods or find a lost person. One Time Activation: $69.95 per unit Monthly fee of $14.95 Locates are $0.49 each Tracking level one for tracking history and zone alerts.
