What products does TLSUN offer?
TLSUN offers two products: the TLSUN Online Survey System (an online survey tool for large, complex social surveys and market research) and the TLSUN Computer-Assisted Personal Interviewing (CAPI) System (an offline survey platform with full-process quality control).
Who is the TLSUN Online Survey System for?
Research institutions, universities, and market research firms that need to handle complex question types and logic while enforcing strict quota management.
What is a paper-like questionnaire?
An online questionnaire presented with the same layout and typesetting as a paper questionnaire — complex question types stay intact and the original logic control is fully preserved.
How do I manage samples and quotas?
Import samples from an Excel file, control access by custom fields, and manage quotas by custom composite variables.
Which projects is TLSUN CAPI suited for?
Door-to-door and intercept interview projects and other large field surveys requiring on-site visits.
How is data kept safe offline?
Interviewers complete interviews without a network connection; the system uses a three-tier data backup mechanism and syncs back to the server once online.
How is interviewer behavior quality-controlled?
The system provides audio recording and GPS location checks, recording the interview process and location for full-process monitoring and quality control.
What formats can data be exported in?
SPSS, Excel, and CSV, with pie, bar, and line chart statistical analysis.
What cooperation models are available?
SaaS cloud service and on-premises (private) deployment. SaaS is rented per project, with TLSUN handling questionnaire digitization, system training, technical support, and server hosting; on-premises deploys the system to your own servers.
