Call blocking phone | block cell phone calls verizon
First thing, that is to be understood here is that those signal blocking devices are not actually blocking electronic devices, such as mobile phones, spy cameras and eavesdropping devices. They simply block all the wireless radio transmissions in the desired area. So if you are using a mobile phone blocker, you will simply block GSM or CDMA frequency. And in that case mobile phones will loose their reception.
So, if you would like to use a signal blocker against any device, that uses radio frequencies to transmit data – you will just have to find out what frequencies it is working with, and pick a jamming device, that is compatible with them. For example, if you need to block CCTV cameras, you will have to get a CCTV signal jammer and turn it on.
It is really good that you are trying to find as many information on signal blockers as you can before using them and we will try to help you with that. First of all, some theory about jamming devices can be found at the articles section of jammer-store.com.
