wiperNumber — i-PRO official camera and recorder MIBs
Number of wipers
Official device manual: SNMP MIB manual for i-PRO camera — version 2.0 (current catalog) — PDF page 38.
Qualified manual context: PDF page 38 prints wiperNumber at .1.3.6.1.4.1.57501.100.1.14.2. The retained native MIB independently declares wiperNumber at 1.3.6.1.4.1.57501.100.1.14.1. This explanatory text is attached to that native declaration; the contradictory manual fields are retained, not substituted for the native assignment or type. Confirm behaviour on the relevant device edition.
