The SMR4000-x is a rugged, ultra low power, high-performance, versatile 24-bit resolution modular multi-channel strong motion recording system. The modular design allows channels to be added in groups of four up to 12channels. The multi-channel units (8 to 12 channels) are suitable for large structure monitoring and include differential sensor inputs to allow long sensor runs in noisy building environments. Multiple sensor inputs are easily connected via twist lock Bendix style connections.

Data streams can be split into virtual streams, applying different event detectors with different trigger bandpass filters and sampling rates while simultaneously recording.

The proprietary Smart Time system, controlled by the DSP, maintains extremely accurate time with only occasional calls to the GPS receiver. Data sampling is precisely synchronized with the internal time so all channels have the exact number of samples within all time periods. Re-indexing of data is never required.

The power hungry components such as the PC, disk, and GPS operate on an extremely low duty cycle. The presence of a powerful PC, however, opens a wide range of options to the user. The industry standard PC/104 allows the use of many peripherals in a modular, stackable format, such as Ethernet cards, wireless LAN cards, satellite communication hardware, etc.
