Thanks for the suggestion. I need a system that is a bit more modular and can integrate with other components. Some of the PIRs need to signal cameras, and I need to support PIRs with specific parameters. For example, I just placed an order for the newly released Optex Redwall SIP-100 that has a 100 meter narrow field of view. That said, the VA6000 would be ideal for a friend who wants to monitor his driveway and front door.
Best, Christopher
