Election Equipment Security


All municipalities within Douglas County use the DS200 Precinct Scanner and Tabulator for elections. The DS200 maintains the highest levels of physical and digital security controls. This paper-based system maintains paper vote records and takes digital images of each processed ballot. Lockable doors, tamper-evident seals and access codes to secure sensitive components and election files assist in making this device secure.


All municipalities within Douglas County have the ExpressVote universal voting system available as a ballot marker, most used by persons with disabilities, as needed or requested. The system provides voter confidence with onscreen printed and audio playback (with headphones) for vote selection verification. The unit's security features physical and system access controls including lockable doors, tamper-evident seals and access codes.
