IPSA 2 radio transmitter connected to a telephone line.

IPSA 2 transmitterVHF range, connected in parallel to the telephone line, is designed for government services and police in strict accordance with the standards for devices and apparatus for outdoor use. This transmitter is enclosed in a waterproof case made of special plastic, designed for long-term use in changing climatic conditions. After parallel connection to the monitored telephone line, the transmitter does not require further maintenance.

When the handset of the controlled device is removed, the transmitter is powered by a built-in nickel-cadmium battery. When the handset is lowered, this battery is recharged by the current of the telephone line. Due to the low current consumption, it is very difficult to detect the fact that the transmitter is connected to the telephone line.
