We are converting our house into a rental property and there is an interior security camera (part of a NEST system) in the main living area Is there any reason I have to remove it when tenants occupy the property?

well if you have had your license suspended for any reason in the last 3 years of buying this insurance its void they wont pay.. so I tell the salesmen Sorry I had my license suspended last year ( we have these stupid red light cameras) and I said the gap is no good for me.. the guy kept on hammering away to get me to buy it..

We have a camera in the common area. 

I didn’t pay extra for the camera.

Get someone with infrared camera it helps.

Neighbors have been watching over with state of the art security cameras but they said they didn't want to get involve so they didn't report anything. 3.

Security cameras are worth every penny.

I have seen some turned into jewelry stores, camera display store, restaurant speakeasy type thing, Fed Ex shipping type place, etc. 

Greg:    First, do not get discouraged by anyone, someone else is doing it so you can, not going to be easy.If not done already I suggest to look into this:Enforce that PM uses a great website for rental screening, ones with a background check and choose the best tenants possible.Review you leases to close any pitfalls and enforce the lease to the T.Keep the units in good shape and keep extra cash reserves ( fixing + trip expenses )Tiger than normal lookup on the PM ( have second PM line up ), vacancies, unit showing costs, repairs, fees, etc,  require a once a week normal operations report and a once a month full operations report.Family, friend on virtual assistant that regularly drive by the property and reports to you, or if cash flow allows and deem beneficial you can install security cameras and remote view activity on the property, nowadays there are lots of options.Check if feasible to get a home warranty plan for the units so some pain issues are self-managed by the tenant via a phone call to the warranting companyIn which city/state is the property? 

This will cover you shall any negligence occurs creating a loss for you.Installing cameras or having security is solely due to your discretion.
