I'm looking for a recommendation for a camera of any brand that will meet my minimal requirements. For the holidays, I set up lights synced to music. I'm looking for a camera that can trigger a relay when a person is detected so I think I just need a camera with a pigtail that can be set up to trigger an alarm. I'm not concerned about the brand, I'm more concerned with the price. Why pay $200 when a $100 cam will do? The camera would be within 50 feet or so of the people.
