  • COVID-19: How to interact with citizens while maintaining your distance and privacy

    Even in a global emergency like COVID-19, police business must go on.

    Although the CDC encourages social distancing to slow the spread of the disease, traditionally law enforcement officers have conducted much non-emergency police work like investigations and accident reports through in-person encounters. This needs to change.

    In response to COVID-19, many agencies are using 10-21 Police Phone to reduce face-to-face encounters with citizens by solving routine police work by phone. For example, a non-emergency call that may traditionally result in dispatching an officer can be addressed over a simple phone call.

  • Callyo Partners with Sonim to Offer Livestreaming Capabilities on XP8

    CARSON CITY, Nev., June 10, 2019 /PRNewswire/ -- Callyo, the leading mobile law enforcement software as a service (SaaS) company, has announced that they have partnered with Sonim Technologies (NASDAQ: SONM) to integrate Callyo's 10-21 Video onto the Sonim XP8 Android mobile phone.

    Currently serving 150,000+ officers and 10,000+ agencies throughout the country, Callyo's partnership with Sonim brings together two types of first responder technologies.

The integration of 10-21 Video allows officers to record video with a click of a button thereby eliminating the need for a standalone camera while on the job. Now officers can use their mobile phone as a dashcam while on patrol, conduct field interviews or go into conceal mode when capturing surveillance all while broadcasting their location and surroundings.

    "We chose to partner with Sonim because of the company's mission-critical technology," said Chris Bennett, Chief Product Officer & Founder of Callyo. "We look forward to expanding functionality and benefits for public safety by bringing our purpose-built law enforcement software to the Sonim purpose-built hardware device."

    The XP8 provides users with an ultra-rugged, easy-to-use experience with its built-in dedicated push-to-talk button, emergency key, long battery life and extra-loud audio. It delivers exceptional toughness by meeting Ingress Protection (IP)-68/69 and Military Standard 810G certifications for hazards, making it waterproof, shockproof, scratchproof and dustproof. The XP8 also integrates a puncture resistant 5" touchscreen that works with gloves or wet fingers and is visible in direct sunlight, while providing up to 35 hours of talk time or 600 hours of standby time.

    Robert Escalle, Sonim's VP of Public Safety Market Segment, welcomed the partnership as a means to demonstrate Sonim's desire to serve those who serve us. "By integrating Callyo's 10-21 video solution onto the XP8, we're able to streamline mobile communications for first responders when seconds count. Having to manage one less device and instant access to video can make all the difference in an emergency situation."
