The video camera I bought is designed to be installed in the rear bumper of a car and used as a reversing camera. When this second stage of the alarm is activated, it is clearly obvious from some distance that we are in distress. However, should it prove necessary, there is a ‘panic button’ concealed near our bunk that we can use to activate the external siren (it’s deafening) and a second blue strobe light. We hope that on realising his presence was known, an intruder might choose to move on and try his luck elsewhere. The installation is visually discreet and guests on board rarely ask what the strange components next to our instruments are for. The two blue strobe lights either side of the camera, the red flashing LED, and the PIR sensor. When triggered, a blue strobe light is activated in the cockpit and a buzzer capable of waking us is sounded inside the boat. With this aim in mind, I installed the PIR motion sensor above the companionway entrance and set its range to reach past the cockpit and onto the rear deck.
An assortment of cables, a mounting box, relays and switchesĪs stated already, personal safety is the key issue we wanted address, and we felt that being woken as someone boards the boat rather than finding them prying open the companionway, or worse, stood over us in bed was extremely important.Small video camera capable of filming in the dark.Blue strobe lights like the ones used in police car radiator grills.A simple flashing red LED light like the ones used to indicate a car alarm is active.The key parts that made it into the final system include: It’s amazing the stuff that’s available on Amazon and eBay. It was time to get more inventive.ĭuring the course of the winter I searched the web and ordered an assortment of parts and gadgets that I eventually cobbled together and installed on board. There are dozens of home and car alarms available which didn’t fit the bill relying on continual broadband connections and using WiFi were just a couple of things we wanted to avoid. Searching the internet for an off-the-shelf solution proved fruitless. there should be some means of later identifying an intruder.in case of an emergency, it should be obvious to other nearby boats that we are in distress,.a motion sensor should alert us if someone boards our rear deck, or approaches our cockpit and companionway entrance (the main entrance to the boat),.as a deterrent, it should be obvious to anyone approaching the boat that a security system is active,.Our shortlist of requirements was as follows: To this end, we decided to look into the options for installing an intruder detection system on board. Leaving European waters and heading further afield raises a question of personal security.
