Alert Hamilton County is paired with a system called “Smart911,” which enables your important information to be shared with first responders during an emergency! With Smart911, both 9-1-1 call takers and first responders can know exactly what you want them to know during any kind of emergency. You can add vital information, such as: information about members of your household, medical details, disabilities and equipment, address and property details, as well as emergency contact information and communication preferences.

What Information Should I Include in My Profile?

  • People – Names, physical descriptions, and photos will help responders act quickly if a child goes missing, or help identify individuals in an emergency.
  • Phones – Add all phone numbers (especially cell phones) so that 9-1-1 will have a better idea where you are when you need help.
  • Animals – Include information about your pets and service animals that responders need to be aware of.
  • Medical Information – Existing conditions, allergies, disabilities and equipment, medications being taken by all members of your household.
  • Address and Location Information – Property details, photographs of your residence, utility shutoff locations, access points to the residence, floor layout and bedroom locations.
  • Vehicle Information – Include a description of your vehicle, as well as the license plate number.
  • Emergency Contact Information – Include the information of family members, friends, or neighbors in the event of an emergency.
  • Communication Preferences – If an individual is deaf or hard of hearing, or English is not the primary language, dispatchers will immediately know that an alternate form of communication is needed.
