Will not work with an aftermarket security system. Useless product. It's too late to return it, but it doesn't fit the normal cables that come with every security system.
Pros
๐ค The microphone comes with a combined power and audio cable, a 1-foot cable with an RCA audio connector and a 2.1mm positive center plug. Catch every sound with an ultra-high gain micro audio system. On-chip integrated preamp, low noise, high gain, and automatic level control
