V1connection, the app. Links the new Valentine One Generation 2 detector directly to your iOS device. It also links the now-superseded Valentine One w/ESP detector through an optional Bluetooth module called V1connection LE. See the Threat Picture, a breakthrough in analyzing radar threats. Screen out false alarms with our game-changing Arrow-in-the-Box concept. Every signal on every band gets its own directional arrow and frequency readout. Flashing arrow points to the Priority Alert. The app brings Dark Mode, Muting, and new programming options. Lets you relocate V1’s front-panel warning to an eyes-only location. New: eSAVVY lets you set a speed below which all new warnings will be muted. Downloads and upgrades are free. NEW FEATURE—DOWNLOADABLE PERFORMANCE UPGRADES FOR V1 GEN2 V1 Gen2 firmware upgrades are downloadable only through this app; downloadable upgrades are incompatible with V1 Gen1 models. YOU’LL SEE THE THREAT PICTURE See our exclusive Radar Locator with its illuminated arrows pointing toward each threat as the Bogey Counter tracks multiple threats. Also shows you a revolutionary new way of analyzing radar threats. ARROW IN THE BOX Radar makers, under penalty of law, must certify to the FCC the frequencies used by the equipment they sell. We constantly monitor those certifications so we know exactly where real radar operates on each band. V1 scans the entire width of all radar bands but to draw your attention to the Active Radar Zones, we outline them with a yellow Box. To be in compliance with federal regulations, all radars (except photo) must operate “in the Box.” When you see an arrow outside the Box, that’s probably a false alarm; when it’s in the Box, take it seriously. ADVANCED SITUATION AWARENESS The Threat Picture (aka Picture Screen) displays a separate arrow for every threat within range, pointing ahead, beside or behind, according to its direction from your car. The arrows grow larger as the signal strength increases. Your visual scan of the Threat Picture lets you see which arrows are in the Box, and spot critical trends—which alerts are maturing into threats and which are fading in concern. SITUATION AWARENESS FOUR WAYS Choose among four information screens at any time. The Quad Screen emphasizes location with up to four separate arrow sets, one for each enabled radar band, or for laser if fewer bands are active. The V1 Screen reproduces V1’s front-panel warnings including signal strength, Bogey Counter and Radar Locator plus frequency of the Priority Alert. Or you can choose the (Threat) Picture Screen or the Threat List, which shows a list of all signals within range, each with an accompanying arrow to show direction. BEYOND SITUATION AWARENESS Think of the app as the Master Controller for your V1 system. You can revise programming, adjust SAVVY settings, change muting, activate dark mode, save custom programming profiles for different trips, and more, all from your handheld. DEMO MODE IS AUTOMATIC. The audible warnings of your V1 Gen2 and V1 can now be transmitted through your phone to your car's sound system, or to speakers in your helmet if you are a motorcyclist. Any other hook-up that allows you to hear your phone can also bring V1's warnings directly to your ear. NEW PROGRAMMING OPTIONS Radar coverage can now be specially tailored to the unique radar bands used outside the U.S. Advanced users may want to modify the sweeps covering frequencies used here in the U.S. according to unique local conditions. The Profiles screen shows a menu of the variables you can modify. For example, you can select "Background Notifications" so that you can run other apps but receive instant notification from V1 whenever a new threat appears. THE APP IS FREE Just download this free app. The Demo Mode plays automatically, giving you a look at all four warning screens playing through preloaded on-road scenarios. For further functions with V1 Gen1 w/ESP you’ll need to purchase V1connection LE.

BART Watch: Free Security App for Riders. The BART Watch App offers the public a quick and discreet method for reporting suspicious activity directly to BART Police. The app can send pictures, text messages, and locations of suspicious people or activities. From the home screen, users have two easy options for contacting BART Police: * The “Report a Problem” button allows users to send text or photos directly to BART Police. To ensure discretion, the camera flash is automatically disabled when photos are taken through the app. When reporting an issue, users can select locations and report categories to assist BART Police. Riders can also send reports anonymously if they chose. * The “Call BART Police” button will connect customers directly to BART Police. The application is designed for BART. If you send a report in an area without cellular connectivity, it will be stored and sent when connectivity returns. The system is also designed to send text messages before pictures so that BART Police can get app reports as quickly as possible. Additional Features BOLO (Be On the Look Out) Alerts. BOLO Alerts on the BART Watch App may display alerts from BART Police about specific persons of interest. For example, BART Watch may display information about a missing person or child, such as where they were last seen. If you see a person from a BOLO, immediately call 911 and send an app report to BART Police discreetly. Help keep BART safe, "See something, Say something."
