Given the recent amount of work done to my bike, registration costs, and the spate of motorcycle thefts, I've been meaning to upgrade my security. Being a younger rider insurance is rather expensive so I've been seeking alternate avenues of protecting my assets. Thus I stumbled upon GPS tracking. At point of writing there exist multiple GPS tracking solutions. However most of these are highly priced, and obscure. Hence I've become interested in experimenting and journalising a method for motorcycle GPS coverage. So far I've purchased custom items to create my own system. Nothing is assembled or received as yet. In coming weeks, the build process will be detailed and results noted. To briefly summarise, my system will consist of a tracking device, and an alarm. The tracking device was recently purchased. Obviously it features GPS tracking, however it comes equipped with GSM/GPRS functionality. This allows the device to broadcast the last known GPS coordinates via text message (SIM card required). This is beneficial given that most GPS receivers are inoperable under a roof. Thus should a motorcycle be stolen, and subsequently garaged, the last location will be SMSed; the point directly in front of the thief's garage. The device is battery powered similar to mobile phones. This is potentially problematic given battery life, however I plan on wiring it permanently into my motorcycle's power supply. A transformer is probably required. I'll seek this one out after the tracker arrives. GPS tracking is generally considered accurate to a radius of approximately 5 metres. Considering the population density in built up areas of Australia, this level of accuracy may be insufficient. A particular GPS location received from the tracker could incorporate several suspects/garages/stores. This is where the alarm is essential. To keep costs minimal I have chosen to rely on my motorcycle's oem horn for the alarm. A wireless activated switch shall incorporated into the horn's circuit. The switch will allow remote controlled activation of the horn. Upon arrival at the GPS coordinates following a theft the remote will sound the motorcycle's horn. At this point the EXACT location of the motorcycle should be clear. This should be enough evidence for the issue of a search warrant issue and possibly the recovery of the motorcycle. Perhaps if you can get a nice enough police officer to accompany you to the scene, you may get the motorcycle back there and then. Hopefully the plan will work out, and I'll be left with a properly functioning security system. All this at $55, thus far. Pictures will posted soon. If I have time, I'll get a friend to "steal" my bike, and see if I can recover it. All on video of course.
