i used a Poisson regression to model species occupancy under a Bayesian approach, here is part of my occupancy model:
#loop each species over all camera stations
for (i in 1:N){ #Number of speceis
for (j in 1:J) { #Number of location
#Poisson model for abundance
#mbeta: community-level parameters; EVN: habitat covariates;
#gbeta: species group covariates......
log(lambda[j,i])
