GSM-001

GSM quadriband audio transmitter

The GSM quadriband audio transmitter is the smallest device of its kind available in the market. The device measures only 39 x 40 x 9mm in size. It is ideal for unlimited remote audio surveillance for locations such as vehicles or rooms. It can be hidden in electrical outlets, junction boxes, switchboards or other household appliances. Owing to its small size, it can be installed in any kind of vehicles even the older models. It has a strong tendency to reject electrical noise or the 50Hz AC voltage noise residue and hence it can be installed on switch panels and even power plugs. This is without a doubt the smallest transmitter in the world presently.

The key feature of this product is a powerful digital signal processor or DSP which reduces and even eliminates background noise. It features two separate programming thresholds in its DSP. The device provides for comprehensive real time sound management. Its algorithm parameters can be modified at the user's volition and it also allows you to choose from two filters both hi-pass and low pass.

It has a special function called the 'Dynamic Mik' which makes the external and on board microphones switch on automatically as soon as the vehicle stops. It provides three separate programmable levels of sensitivity. It has awesome features of SMS initiated remote programming with a DMTF tone emission when received, recall on moving towards the base station with self-breakdown function and recall on VOX function and threshold setting at various levels.

It has protection against non authorized or accidental reprogramming via a virtual lock. It also disallows a non authorized user to list the unit as it has a single listing functionality. It can switch off immediately for a specific period of time by its remote stealth functionality. You can even go for a fast reset which immediately reverts to default factory settings. In cases of no events you can use the 'infinity' function for continue call listening. There is an added feature of remote diagnostic including unit IMEI, main cells and all other secondary cells with signal straight.
