TrailMaster’s TM1550 is a Second Generation two-piece active infrared trail monitoring system which uses an invisible infrared beam across the trail between the transmitter and receiver. (150 ft./45 m. range) The infrared energy is transmitted as a wide beam from the transmitter, and received in a small 3/8" diameter window on the receiver. The only part of the transmitted beam which is sensitive to being broken is the narrow 3/8" beam which is received by the receiver. See Figure 1 below. By setting the beam at the chest height of the animal you wish to monitor, and controlling the length of time the beam must be blocked before it registers as an event, you can count only the animals you want, and ignore other animals or objects which pass through the beam. This patented TrailMaster system provides a monitor which is easy to align, but one with selective sensitivity to allow you to monitor for movement of specific game. The TM1550 Second Generation two-piece active infrared trail monitor and its accessories are the standard by which all other trail monitors are measured. Two piece Active infrared technology sets the standard in trail monitoring technologies.

The TM1550's Patented Two-Piece Active Infrared technology has been found to be the most accurate technology available for use in traffic counting and trail counter applications. TrailMaster's Patented Two-Piece Active Infrared technology is the standard by which all other trail counters are measured.
The standard TM1550 has a memory capacity to record a minimum of 1,000 events. The TM1550-4K has a memory capacity to record 4,000 events. The TM1550-8K has a memory capacity to record 8,000 events and the TM1550-16K has a memory capacity to record 16,000 events.

Each time an animal passes through the infrared beam, the event is recorded by date and time to the minute. This event information is stored in the TM1550’s non-volatile memory. If the optional TM35-1 Camera Kit is attached, the TM1550 system can also take a photograph of the animal as it breaks the beam. The TM1550 lets you record and store more than 1000 events. With the TrailMaster TM1550 you can collect event information and take photographs which will show patterns of game movement and prevent drawing incorrect conclusions based on a small number of events.

No other product offers the advantages of the TrailMaster Second Generation Active Infrared trail monitoring system.

The TM1550 trail monitor has many features which make it ideal for field use. An alignment light is built in, making it easy for one person to position the system. The large digital display is easily read and the simple data retrieval method allows you to review the time and date of each event as many times as needed. Defaults are programmed in so that the unit will automatically begin collecting data even if the operator forgets to set the proper mode.

Three push buttons on the front of the receiver are used to control its many functions. The TIME SET button is used to set the initial time and date functions in the same way a digital watch is set. The SET UP button is used when aligning the transmitter and receiver. Proper alignment is verified by a blinking red light on the receiver. This red alignment light is on only during the set up process, and goes out automatically after four minutes even if the operator forgets to take the unit out of the Set Up mode. The READ/OUT ADVance (R/O ADV) button is used when reading out the data. Subsequent depressions on the R/O ADVance button will cause the date and time of each recorded event to be displayed in sequence on the digital display.
