Security Cameras - Invasion of Privacy?

[Zach Schwarzmiller]

I am debating installing security cameras on my triplex, but am concerned about legal issues. A couple of my concerns are as follows:

- If they malfunction and an incident happens outside my triplex. Am I liable because the victim thought it would be recorded and it was not?

- Is there any invasion of privacy issues associated with this?

I would leave sound recording off but want to monitor video.

My cars along with multiple neighbors cars have been badly keyed recently and I have a very problematic tenant as well.

If anyone has any advise who I could contact in regards to these questions it would be greatly appreciated. I don't see anything about it in the Landlord Tenant Laws, but that does not mean it could still be an issue. My property is located in Snohomish, Snohomish County, Washington State.

Thank You!
