Cell phone block - cell phone blocker norfolk
Hi there, corporatehater!
First of all - we are sorry for the delay with an answer! You should understand that you Drive Cam, and the whole GPS tracking system may loose satellite signal due to many various reasons, and there is no way to tell, if that was your fault, or that is a simple technical issue. In a matter of fact, the backup battery installed in that system may die, and if you will park your vehicle – the signal will be lost too.
Also, we can assure you that the two-way radio, that you use to communicate with a dispatch won’t be jammed with a GSM, or GPS signal blocker. In order to block that radio, you will have to use a special jammer, that works with 433.3, 868 and 315 Mhz frequencies, which is quite hard to find. We understand your doubts about using the signal blocker, but you have to understand and always keep in mind the fact that any kind of RF jammer is like a weapon, and you should use it with the same caution and full understanding of the problem, like you may do with a weapon. It is not a toy. Another problem you should consider here, not any signal blocker will be able to block such a tracking. If you will use a simple GPS blocker – you may still be tracked with a cell phone tower triangulation and all the data gathered by Drive Cam will still be sent.
I’ve consulted with our engineering team about your idea with an earth magnet, and they have advised not to do that. First of all that won’t be really effective, and if you will accidental forget it near the device, the first service check will notice that. Second, as long as all the data is transferred with GSM or CDMA standard, which are almost immune to magnetic fields – that won’t simply work. You may try it yourself, by keeping a magnet near your mobile phone during the conversation – there won’t be any effect. That is why we recommend you to check that universal GSM/GPS and CDMA jamming device, it will keep all the data transmissions blocked for sure!
Thanks for your question, I hope, I’ve managed to help!
