A spy video camera is your best friend if you want to do undercover surveillance work. These cameras are particularly useful sports earpiece for private investigators and people who are interested in spy gadgetry. Suffice to say, a spy camera is most effective when it is hidden in pieces of clothing or wired to the human body. Body worn spy cameras are so dependable that they can produce high quality video even in the most pressing situations.
It's a good idea to take your earpiece for hearing battery out of the device at night while it's not being used. During this time, you should ventilate the battery compartment of your 1999 earpiece. This will prevent moisture from getting into the battery compartment and causing damage.
The only thing lacking is a hands free for the helmet. However, with so many other things included with the unit, this is not as much as a problem as it first appears. Also, there are quite a number of Bluetooth-integrated helmets and standalone earpieces for helmets that you can buy at a reasonable price.
You should think about the range that your employees or you need to have (that is the distance from the base that you need). Do you need 10 ft, 20 ft, 300 ft. This is the amount of movement capability you will have once you are using the office style headsets. If you need greater than 20ft, using a hand free earpiece is your solution.
Certainly, there is the convenience factor that comes with a Bluetooth earpiece, but in the sake of looking sharp, how about keeping it in your pocket until you actually need it? Chances are pretty good that you'll actually do yourself a favor by saving the battery life, as well as upgrading your look by doing so.
