  We summarize recent results on the infrared (IR) nuclear properties of
Seyfert galaxies. 100% of all Seyfert 1-1.9$ and ~50% of all Seyfert 2s in the
CfA and RSA samples observed with HST/NICMOS show nuclear point sources at
1.6micron. We find that the unresolved emission is variable in 9 out of the 14
Seyferts with duplicate observations, indicating a non-stellar origin. We have
also put together non-stellar 0.4-16micron spectral energy distributions (SEDs)
for the entire CfA sample of Seyfert galaxies. The shape of the SEDs for a
complete sample of AGN can be used to constrain torus models.We report a good
correlation between the IR and hard X-ray luminosities of local universe AGN
suggesting that their mid-IR emission is approximately an isotropic property,
and thus can be used as an indicator of the AGN luminosity. Finally we show
that the hard X-ray and mid-IR luminosities appear to be related to the black
hole mass in AGN.
