TrailMaster’s TM1550-PS 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), just like the TM1550, however the –PS has advanced camera controls available. 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-PS 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.

|Wildlife photographer Michael "Nick"Nichols and his work using TrailMaster TM1550-PS....
"Some animals are so afraid of humans that its nearly impossible to photograph them up close. In 1993, I first experimented with TrailMaster cameras triggered by the animal breaking an invisible beam..." continued
The TM1550-PS has additional camera controls that allow the user to tailor the control signal that is sent to the camera when an event is detected. By allowing the user to modify the control signal the user can select how many pictures will be taken when an event occurs and if, or how long the delay will be between the photographs when multiple photographs are going to be taken on a single event. The user can also select if the additional pictures will, or will not, be taken if the IR beam is not still broken at the time the additional picture would be taken.
Additional Camera controls;
- The length of the camera activation signal.
- The number of consecutive photographs to be taken when an event occurs.
- The delay between consecutive photographs. (This is not the same as the camera delay.)
- Whether the additional photographs will be taken if the IR beam is not still broken when it is time to take the next photograph.
Example 1. If a user were using a TM1550-PS with a TM35-1 camera kit or a Canon EOS 350D or a Nikon D70s or another camera and wanted to take three picture when an event occurred, but because a strobe was being used, a five second delay between the pictures was needed, this could be easily be accomplished with the TM1550-PS.
Example 2. If a user were using a TM1550-PS with a old TM35-1 camera kit using a Olympus Twin, or a Nikon N90s or another camera with a continuous mode and wanted to take photographs as fast as possible for 1.5 seconds after an event was detected the TM1550-PS could accomplish this task easily.
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.
Each time an object passes through the infrared beam, the event is recorded by date and time to the minute. This event information is stored in the TM1550-PS’s non-volatile memory. If a camera is attached, the TM1550-PS system can also activate the camera to take the selected number of photographs of the object as it breaks the beam. The TM1550-PS lets you record and store more than 1000 events. With the TrailMaster TM1550-PS you can collect event information and take photographs which will show patterns of activity and prevent drawing incorrect conclusions based on a small number of events.

* NEW FEATURES ON THE TM1550
product offers the advantages of the TrailMaster Second Generation Active
Infrared trail monitoring system.
The TM1550-PS 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 multi-function 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 SET UP button is also used to access the settings for the advanced camera controls. 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.
TrailMaster supplies many special cables necessary to interface a wide verity of cameras to the TM1550-PS. If you have a question about camera compatability please email us.
