In the work of maintaining social order and ensuring public safety, patrol teams, as an important force in grass-roots public security prevention and control, the practicality and efficiency of their equipment directly affect the work effect. With the continuous development of acoustic technology, handheld AHD (Acoustic Hailing Device) has gradually entered the field of patrol equipment. RIBRI, a company focusing on acoustic technology R&D, has launched a variety of handheld AHD equipment suitable for patrol scenarios since its establishment in 2006, relying on its in-depth cultivation in the acoustic field. Based on the daily work needs of patrol teams, combined with the technical characteristics and practical application scenarios of RIBRI handheld AHD, this article will analyze in detail the specific help of handheld AHD to patrol teams.
I. Work Pain Points of Patrol Teams: Why Professional Acoustic Equipment is Needed?
The core work of patrol teams revolves around three major areas: public security inspection, emergency response, and safety promotion. In actual implementation, they often face pain points such as low communication efficiency, insufficient deterrence, and low handling safety:
- Long-Distance Communication Difficulties: In open areas such as large squares, industrial parks, and main roads in towns, traditional sound amplification equipment (such as hand-held megaphones) is limited by volume and propagation distance, and the sound is easily covered by environmental noise. This makes it impossible for patrol officers to quickly transmit early warning information and evacuation instructions to the crowd. When patrolling at night or in bad weather, the communication effect is further reduced, which may delay the emergency response time.
- Upgraded Demand for Non-Violent Handling: When facing scenarios such as gathering to make trouble and suspects refusing to cooperate, patrol teams need to control the situation without using force. Traditional methods such as physical blocking and verbal persuasion are not only inefficient but also may lead to the escalation of conflicts, posing the risk of injury to team members and the public. There is an urgent need for a handling tool that can effectively deter without causing harm.
- Insufficient Coverage of Safety Promotion: In daily patrols, it is an important task to popularize "four prevention" knowledge (theft prevention, fraud prevention, fire prevention, etc.) to the public. However, traditional promotion mostly relies on posting posters and door-to-door explanations, which has limited coverage and is time-consuming and labor-intensive. In places with a large flow of people, it is difficult to quickly transmit safety knowledge to more people, resulting in a greatly reduced promotion effect.
II. Core Advantages of RIBRI Handheld AHD: Accurately Matching the Needs of Patrol Teams
As a leading enterprise in the domestic acoustic technology field, RIBRI's handheld AHD equipment relies on the standardized production process of its 2,600-square-meter production base and the test guarantee of the semi-anechoic chamber certified by the metrology institution. It has been optimized for patrol scenarios in terms of performance, safety, and applicability. The specific advantages are reflected in the following three aspects:
1. Super Strong Penetration and Clarity to Solve the Pain Point of Long-Distance Communication
RIBRI handheld AHD adopts advanced directional acoustic technology. Compared with traditional sound amplification equipment, the sound propagation distance is longer and the directionality is stronger. Its equipment can achieve a volume increase of 30-40 decibels. Even in noisy environments such as busy cities and construction sites, it can ensure that people within 100-800 meters can clearly hear voice instructions. This distance covers high-frequency patrol areas such as town main roads, large farmers' markets, and parks. For example, during peak tourist seasons in scenic spots, patrol officers can quickly broadcast the crowd evacuation route through the handheld AHD, avoiding the dilemma of traditional megaphones where "no one listens even if you shout your throat out". When patrolling at night, for suspicious persons in remote sections, they can shout and ask from a long distance through the equipment without approaching closely, improving the safety factor of the officers themselves.
At the same time, RIBRI handheld AHD supports both real-time voice broadcasting and pre-recorded instruction playback modes. Patrol teams can pre-record common instructions such as "Please evacuate in order", "No staying here", and "Please evacuate immediately if a fire is found", and play them with one click in emergency scenarios to save communication time. The equipment also has anti-interference ability, and can maintain sound clarity in bad weather such as wind, rain, and sand, ensuring that the transmission of instructions is not interrupted.
2. Non-Violent Deterrence Function to Improve the Safety of Emergency Response
When patrol teams face sudden conflicts (such as fights and gatherings to make trouble), the primary goal is to quickly control the situation and avoid personal injury. One of the core advantages of RIBRI handheld AHD is its "non-harmful deterrence" capability. The equipment can emit warning sounds of specific frequencies. When used in a standardized manner, the sound can cause slight discomfort to the human body (such as tinnitus and irritability) but will not cause substantial harm. It complies with IP65 dust and water resistance certification and CE safety standards, and poses no risk to the health of patrol officers, the public, and suspects.
In practical scenarios, if a suspect resists arrest or the crowd refuses to cooperate with evacuation, patrol officers can turn on the warning sound function of AHD. On the one hand, the high-frequency warning sound can quickly distract the attention of the troublemakers and weaken their willingness to resist; on the other hand, the sound can transmit "danger warning" to the surrounding public, guiding them to take the initiative to stay away from the dangerous area and preventing irrelevant personnel from being involved in the conflict. Compared with traditional physical handling methods, this "non-contact deterrence" not only reduces the probability of patrol officers being injured but also reduces the escalation of conflicts during the handling process, which is in line with the needs of "flexible law enforcement" in grass-roots public security work.
3. Lightweight Design and Durability to Adapt to Diversified Patrol Scenarios
The work scenarios of patrol teams are complex and changeable. They need to patrol on foot in the back streets and alleys of towns, and also patrol by car in open areas. Therefore, the equipment has high requirements for portability and durability. RIBRI handheld AHD fully considers this demand. The equipment weighs only about 4.8 kilograms, and team members can hold it with one hand without obvious sense of weight when carrying it for a long time. The equipment shell is made of high-strength wear-resistant materials and has passed the IP65 dust and water resistance test. It can work normally in the temperature range of -20℃ to 60℃. Whether it is used for patrolling in rainy days, on-duty in high-temperature weather, or in town sections with more mud and dust, it is not easy to be damaged.
In addition, the battery life of RIBRI handheld AHD is also adapted to the work rhythm of patrols. The equipment supports continuous work for more than 4 hours, which can meet the all-day on-duty needs of patrol teams for "morning shift + evening shift". Team members can recharge the equipment at any time through the patrol car's on-board power supply and power bank, without worrying about the equipment being powered off. This "lightweight + high durability" design allows the handheld AHD to be seamlessly integrated into various patrol modes such as foot patrol, car patrol, and fixed-point guard duty, becoming a "portable tool" rather than a "burden" for patrol teams.
III. Handheld AHD is a "Practical Partner" for Patrol Teams
Based on the work pain points of patrol teams, combined with the technical advantages and practical application effects of RIBRI handheld AHD, it can be clearly stated that handheld AHD is of significant help to patrol teams. It not only solves the problems of low long-distance communication efficiency, insufficient emergency response safety, and poor equipment portability but also can improve the work efficiency and safety of patrol teams through functions such as non-violent deterrence and efficient promotion.
As an enterprise focusing on acoustic technology, RIBRI's handheld AHD equipment fully adapts to the work needs of grass-roots patrol teams through standardized production, strict quality certification, and scenario-based design. For different types of prevention and control forces such as town patrol teams, urban community patrol teams, and industrial park patrol teams, equipping with handheld AHD is not an "unnecessary investment" but a "practical tool" to improve the ability of public security prevention and control, ensure the safety of team members, and optimize the public service experience. Under the background that grass-roots public security work is constantly upgrading towards "refinement and technology", handheld AHD is expected to become a "standard equipment" for patrol teams, contributing more to maintaining social order.
