Core Functional Features
Dual Ultrasonic Emitters Deliver Stronger and Wider Sound Coverage
Most ultrasonic bark control devices on the market use a single ultrasonic emitters , which disperses ultrasonic energy over a limited area. uneven signal and weak long-range deterrence. The TZ-U79D automatic ultrasonic bark control features two synchronized ultrasonic emitters can emit concentrated, wide-area ultrasonic energy, covering a range of 5-15 meters with no blind spots;


3 Frequency Modes Prevent Dog Desensitization (Lower Return Rate)
25kHz fixed / 30kHz fixed / 20–30kHz auto sweep frequency.
Single fixed ultrasonic waves will cause dogs to get used to stimulation after weeks of use, leading to mass negative reviews. Dynamic auto-sweep continuously changes sound wave spectrum to maintain stable training effect long-term. Reduce return volume caused by "device stops working after one month", lower customer service workload and after-sales compensation cost.
Intelligent Bark Recognition Algorithm
The TZ-U79D incorporates an optimized bark recognition algorithm that analyzes barking characteristics instead of reacting to simple sound volume.
The algorithm is designed to: Identify dog barking frequencies, Filter human voices, Ignore common household noise, Reduce accidental activation. By delivering ultrasonic correction only when genuine barking is detected, the device helps improve training efficiency while minimizing unnecessary stimulation.


Dual Working Modes: Ultrasonic / Ultrasonic + Strobe
The ultrasonic mode is suitable for dogs with sensitive hearing; the high-lumen synchronized strobe light + ultrasonic mode provides a dual visual and auditory deterrent for stubborn dogs that are slow to respond to sound. Compared to using ultrasonic alone, this dual-response method is more effective at stopping a dog's barking, especially in outdoor environments where visual attention is crucial.


I200mAh Large Li-Po Battery with Ultra-Long Standby
This U79D automatic ultrasonic bark control with a 1200mAh high-capacity lithium polymer battery, it can be fully charged in just 2 hours using any 5V standard charger (including power banks, laptop chargers, and car chargers). A full charge provides up to 30 days of continuous operation and up to 60 days of standby time. overcharge & over-discharge protection circuit, built-in safety chip avoids battery swelling failure.
HD LCD Real-Time Display
Exclusive LED screen real-time shows current ultrasonic frequency and detection range; multi-color indicator lights display charging, standby, low power and working status.
Most low-cost competitors only have simple indicator lights without digital screen; end users easily confuse settings and send lots of consultation messages to your store. Clear digital reading reduces operation misunderstanding.
Cut your after-sales customer service workload, fewer consultation tickets about "how to adjust modes".


Application scenarios
Simply place the device where barking frequently occurs.
Ideal locations include: Front doors / Backyard / Balcony / Garage / Garden / Living room / Pet room
The automatic operation makes it convenient for daily pet training without continuous user intervention
How It Works
TIZE U79D automatic ultrasonic bark control adopts intelligent voice recognition microphone to capture dog barking within your preset distance. Once barking is detected, the unit automatically releases adjustable ultrasonic waves that only dogs can perceive; stimulation stops immediately when dogs stay quiet.
After repeated training cycles, dogs build conditioned reflex to link excessive barking with mild, painless auditory discomfort and stop noisy behavior voluntarily.
The auto-sweep frequency design prevents habituation, delivering stable long-term training results for all breeds, multi-dog households and neighbor barking issues. No electric shock, no skin abrasion, fully humane pet training solution.

After-Sales Guarantee
12-month global warranty for all bulk orders;
For non-artificial quality defects (mic failure, abnormal ultrasonic output, battery charging failure), we support free replacement or supplementary goods in your next order;
Quality problem handling process: Provide clear photos/videos of defective products for verification, we give solutions within 24 working hours;
We bear replacement cost for mass quality issues caused by factory production flaws.
