ShotPM.com – Weapon Shot Counter (WSC) for Preventative Maintenance and Inventory Management using Radio-Frequency Identification (RFID) chips


The ShotPM firearm accessory is a small hardware module designed to be attached to any firearm with an M-Lok rail solution. It incorporates a compact accelerometer to count shots fired and a radio transceiver (using the 2.4 GHz unlicensed band for radio communications with IEEE 802.15.4 standards) to relay this information back to persistent data storage located on a PC server or in the cloud. Radio communications are silenced automatically once the ShotPM accessory becomes out of range of an active gateway unit.

The ShotPM solution is derived from the popular V-Tag asset tag manufactured by InfinID Technologies. This means that it supports mesh networking. With mesh networking, simply place a few fixed tags at strategic locations in the armory or gun range, and the shot tracker can relay messages through these fixed tags to a gateway unit for a robust and reliable shot reporting solution. The gateway unit is hooked up to Ethernet or Wi-Fi and usually a single gateway unit is sufficient for a large area. In addition, the location of firearms can be queried periodically using the fixed tag network. This provides confidence that all firearms are accounted for and location history and custody records can be reviewed by any authorized users.

Shot data is integrated into a secure variation of the APB360.com (GunTRAC LLC) platform (an industry leading inventory and firearm training and tracking system) which provides real-time information on which rifles need maintenance, the maintenance history, chain of custody and optionally location. Alternatively, Windows compatible software can be installed to handle basic record keeping without the use of APB360.com. The APB360 system can be used on or off premises or cloud based. Firearm malfunctions can also be identified depending on the type of malfunction. In addition, APB360 provides interactive electronic standard operating procedure templates for asset inspections and maintenance. Armorers will no longer miss important inspection steps and authorized users may update any procedure in real-time.

Preventative Maintenance

ShotPM allows armory personnel to more efficiently maintain firearms, by not replacing springs or other internal components until a minimum threshold of shots has been fired. Reports can be generated to identify weapons requiring maintenance. The streamlined maintenance record keeping process will reduce malfunctions and improve accountability across any organization implementing ShotPM.

In addition to keeping a count of shots fire, ShotPM keeps a separate count of “high energy events”, such as a rifle being dropped or bouncing in a vehicle during transport. This can assist with maintenance operations planning. For example, weapons stowed vertically in vehicles which embark on poorly maintained roads or off-road conditions will be able to account for spring wear.



ShotPM is a mesh network tag.  With mesh networking, simply place a Fixed Tag at each strategic location in the armory or gun range, and the device can relay messages through these fixed tags to a gateway unit for a robust and reliable shot reporting solution. Utilizing this technology, each rifle will automatically report what location it is currently at for each shot fired as well as through configurable hourly sensor reports. The ShotPM solution associates a unique RFID identifier with each firearm that may be electronically queried in the armory or gun range. This assists in periodic audits and the tracking of individual firearms. Once the ShotPM accessory is within range of the gateway or a sufficient chain of fixed network tags, the data may then be accessed to generate shots fired reports accessible on phones, tablets, laptops or desktop computers. The 2.4 GHz unlicensed band is used for radio communications, using IEEE 802.15.4 standards.

Battery/Power Source

The ShotPM accessory is battery powered using the popular CR123A lithium battery. The batteries are field replaceable. Battery life is between one to two years depending on level of usage.
