Let a Knock at the Door Trigger Your PHV 1330 Peephole Viewer to Start Recording
If you already own or plan to purchase the Brinno PHV1330 Digital PeepHole Viewer and Recorder, the Brinno KNS100 Knocking Sensor is a great accessory. It was designed to fit perfectly inside of the PHV1330 Digital PeepHole Viewer and Recorder so there is no difficult installation required. It simply snaps into the extension port of the PHV1330 (see image below). Upon sensing a vibration from a knock on the door, the sensor tells the PHV1330 to start recording images. So even if you are not at home, you will know who knocked on your door.
See who’s knocking!
