Safe and Compliant
NIGHTWATCH® complies with the limits for a Class B digital device, pursuant to Part 15 of the Federal Communications Commission (FCC) rules, and further ensures compliance with Industry Canada (IC) license-exempt RSS standards, PTCRB/CTIA certification standards, and IEC (International Electrotechnical Commission) 60950 product safety standards.
NIGHTWATCH® uses novel radio frequency technology (ie, ultra-wideband impulse radar [UWB-IR]) to monitor your horse’s heart rate and respiratory rate, the two most important vital signs that correlate with pain and acute distress in horses. UWB-IR is a safe and very low energy radio-frequency technology that measures physical changes in the vasculature and soft tissue beneath your horse’s skin that correlate with their heart rate and respiratory rate.
NIGHTWATCH® uses a variety of sensors, including an accelerometer, gyroscope, magnetometer, and an altimeter to continuously assess your horse’s activity, motion, and posture. More specifically, NIGHTWATCH® identifies and flags (for evaluation) first-time novel events that may be indicative of distress along with known movements that likely correlate with distress such as pawing, kicking, flank watching, repeated rising/falling, extended periods of recumbency, violent rolling with/without thrashing, etc.
NIGHTWATCH® offers two alert modes, smart and manual. In smart mode, thresholds are your horse's EDI® score where as in manual mode you can customize thresholds on any of the other 4 metrics, including their heart rate, respiratory rate, how often they roll, and how much time they spend lying down in a laterally-recumbent position.
Smart Mode: When your device is placed in the smart mode, the system is looking for deviation in your horse’s normal physiologic parameters (i.e., biometrics, behaviors) that correlate with pain and distress. This mode requires a “learning” period of up to 30 days while your horse is healthy and in their normal and natural environment.
Manual Mode: When your device is placed in manual mode, you have the ability set your own thresholds for up to 4 parameters to trigger an alert. By placing your device in manual mode, you can utilize your device immediately out-of-the-box and bypass the “learning” period that is required in smart mode.
When distress is detected, NIGHTWATCH® will alert you and up to 4 others via text, voice, and email simultaneously as a broadcast until the alert notification is acknowledged. A status LED on the ID plate of each NIGHTWATCH® halter further offers a visual indicator of your horse’s relative distress. Just look for the green light for reassurance your horse is happy and within their normal/non-distress state.
Your horse’s EDI® score is an objective measure of their relative distress and general well-being, and derived using a fuzzy inference system with multiple parameters, including biometric and behavioral inputs, environmental conditions, pre-existing risk factors, and more.
Biometric data: Vital signs
Behavioral inputs: Activity, motion, posture
Environmental conditions: Location, time of day, etc.
Pre-existing risk factors: Medical history, habits, etc.
The EDI® is a proprietary 10-point scale, offered exclusively by NIGHTWATCH®, used to quantify relative distress in your horse at any given point in time. The lower your horse’s EDI® score, the happier and healthier they are.
