Home Assistant configuration using the REST Switch integration to control the white supplemental lights on Hikvision/Annke ColorVu or NightChroma color night vision cameras.
#
# # REST Switch configs for toggling the white "Supplemental Lights" on Hikvision/Annke cameras
#
# Note that we must hit the cameras' ISAPI endpoints directly, not through the NVR,
# since (at least the Annke N88PCH) NVR does not seem to support getting nor setting the
# `/ISAPI/Image/channels/<ID>/supplmentalLight` API endpoint. This also implies that
# we must use the NVR's "integration password," i.e. the username and password used by the
# NVR to automatically config the cameras, NOT a user of the NVR itself.
