Thanks so much for your response. It’s very helpful the advice you gave. Sorry, if the BaoFeng isn’t a good example to use, maybe another kind of 2 way radio?
I still have a couple more questions. First, I’m currently working overseas in Korea and I was told that walkie talkies here (probably FRS?) didn’t require any license to use. I’m parked in a quiet place so I’m not worried about “other” noise that might keep the VOX transmitting all the time. Also, when you said that if the radio on VOX keeps transmitting via other constant noises, that seems to indicate that you are saying the VOX sensitivity is REALLY sensitive if it can indeed pick up and transmit a car passing by or even some people walking by talking. I was led to believe that VOX are usually not sensitive enough that nothing would get picked up unless you spoke DIRECTLY into the unit. So I’m not sure now who is right. Is VOX really that sensitive? (It’d be great if it is as sensitive as you seemed to indicate). Also, aren’t there plenty of channels or PRIVATE channels I could use so that even if I was transmitting a lot, nobody would be disturbed and constantly alerted via my VOX transmissions and cause some unwanted attention by authorities?
I contacted another business and they told me that VOX radios that transmit over FRS can only output .5 watts so that means the range might be much more limited than I thought. I’m expecting at least 1 to 2km but if VOX can only output .5W at FRS, how much range do you think that would give me with very little obstruction?
Last but not least, I was made aware about car alarms that now also work with smartphone apps where you can remotely arm and disarm, start engine, lock/unlock, and even be alerted if alarm is triggered via smartphone app no matter where you are or how far you are. This sounds really great, except for one thing, I’m not a smartphone user (yet). Plus, I already have an alarm system setup in my car.
If I were to go this route, I’m guessing it would cost me an enormous amount because I’d have to buy everything from scratch just for the sake of using it as a car alerter/notifier.
I’m assuming these would be new expenses:
- buy a new car alarm that works with smartphone apps ($400-$600?)
- buy a new smartphone w a data contract ($0 to $500)
- pay monthly for my new smartphone bills + data ($50-$100?)
That’s like over 1k I’d have to invest in. Right now I only pay $15 bucks a month for my regular flip phone since I sparingly use it. I only require it for some texting and few minutes of calls per month. Does it make sense for me to have to get a smartphone + contract + data plan just so that I can use the car alarm app?
It still seems to me that going the walkie talkie route is much cheaper for me even if it’s not as good as the smartphone car alarm combo. $100 vs $1000.
That’s what I’m thinking. Correct me if I’m wrong. Plus, as I’m only here temporarily, investing in the smartphone + car alarm doesn’t seem like a great idea for me also if I’m only going to need it for another year or 2. The walkie talkie or some sort of VOX device seems much simpler to get and to get rid of when I don’t need it anymore.
Please advise once more. Might you know of any other option where I can use some sort of proximity sensor device that can notify me via pager/text/key fob alerter etc. if 2 way radios REALLY isn’t going to work for me?
