A description of how surveillance technology has been used, including whether it captured images, sound, or information regarding members of the public who are not suspected of engaging in unlawful conduct: This technology has been used to provide emergency services to individuals who have initiated a 911 call. For a landline 911 call, Advanced/Next Gen 911 has provided the name/s of the individual/s who procured the landline and its location. For Cellular based 911 calls, Advanced/Next Gen 911 has provided callers locations based on cell tower locations. During the course of the previous year, we have also requested cellular providers ping subscribers phones to get a more accurate location of the caller. The reasons for these requests include the fact that the caller may be in imminent danger, the caller is a potential suicide risk, or the caller is the victim of an ongoing crime. The texting feature of the 911 system also allows access to the location of the phone that sent a 911 text. This technology does not capture images and does record the voice communications of the caller and the E911 operator. 2.
