If the cameras are pointed to capture personal activities on your property and in your house, they are technically committing an offense of eavesdropping. Law enforcement has to go to DAs and judges to get orders for just that type of observation (I was both a judge and a DA). This is a clear invasion of privacy. You do have a clear expectation of privacy to be able to do what you want in your house and on your property. I would report it to the El Paso County DA's Office ASAP and contact an attorney about getting an injunction against them for continuing to doing this.
