The Speco Technologies 2WAK2 Two-Way Audio Kit is used with DVRs that feature 2-way audio support. It includes the PVL15 Amplifier, DMS3TS Speaker, CAMMIC Line-Level Microphone, and PSW5 Power Supply (for microphone). With this 2-way audio kit, a person can communicate with someone in view of a camera either directly through the DVR or with an Apple or Android application. Suitable for use in small areas such as classrooms, retail shops, or convenience stores, the PVL15 Amplifier provides priority paging, 15W of RMS power, and has 3 easily accessible inputs. It also offers Mic1 priority mute function with front button and has separate bass and treble controls.
The DMS3TS 4" Speaker is a 3-way indoor/outdoor all-purpose speaker system with a 70/25V transformer. It features a 4" polypropylene air suspension woofer and 1" dome tweeter housed in a die-cast enclosure. The add-on CAMMIC Mini Microphone can be connected to an amplifier or DVR via a line level input instead of a microphone level input. This provides flexibility on amplifier or DVR units that have all microphone inputs occupied or that don't have a microphone input at all. This microphone is suitable for recording channel-specific audio on DVRs which offer that capability. This microphone is powered by the included PSW5 12 VDC Power Supply.
