Intelligent heart rate watch

GPS watch,GPS tracker,kid safety tracker,GPS location,GPS tracking

The smart heart rate watch is a watch that can monitor the heart rate, and it can’t be taken off in addition to monitoring the body temperature. It can be mainly used for patients with confirmed or suspected infectious diseases and other monitoring objects. The strap is made of high-strength Pu and metal layer, which is not easy to be damaged. If it is cut by tools, an alarm will be given immediately. With built-in Beidou / GPS positioning chip, it can accurately locate and is waterproof.

High-level intelligent heart rate watch

This is a small and delicate smart heart rate watch. Compared with many bulky and bulky watches, pt99ht is very delicate. At the same time, it also introduces a number of advanced explosion-proof designs. The strap can withstand the high-strength tensile test. The main body of the watch has passed the hammering explosion-proof test. The overall water-proof design, hand washing, rainwater, and bathing are all in the same place Rate watch gives people great self-esteem protection, but also plays a practical monitoring role.

Waterproof design IP67

Buckle anti disassembly design

As shown in the left figure, the design of the whole table body is very strong and durable, explosion-proof and tensile design, which fully conforms to and exceeds the design specification of epidemic monitoring and correction table. The fastener fixed on the watch strap is made of plastic with this strength, and it is locked with a specially designed screw. It cannot be opened without a specially designed tool. Even if a professional tool is used, it will start to remove the alarm when it is opened, and the monitoring center can immediately receive the alarm information so that there is no place for community correction personnel to escape.

Anti explosion and anti disassembly design of watch band

Take a look at the design structure on the right. First of all, the integrated design of the strap and the main body is carried out. In addition, the connection head which makes the watch more difficult to remove is adopted. The design of an embedded metal sheet in the watch makes the strap have stronger tensile and shear properties. The wristband adopts the medical-grade Pu used by the sports watch, which makes the wearer more comfortable without any allergic reaction. The strap can be adjusted according to the size of each person’s wrist.

Beidou precise positioning

Pt99ht integrates Beidou and GPS dual-mode positioning to make positioning more accurate. The wrist watch has different positioning modes. The tracking mode enables the device to send the location to the server more frequently. Through the app, the device can be tracked. In the power-saving mode, it can enter the sleep state when the watch is not moving much, which makes the watch more energy-saving. Through the electronic fence, we can accurately know the time when the monitored objects enter and leave a certain area, and send an alarm on the monitoring platform.

SOS button and position report

In some community correction systems, the community correction personnel will be required to report the position regularly, that is, to punch in. There is a special button on the watch, which can report their position after a few seconds of pressing this button, so as to prevent false alarms. When the community correction personnel punch in, the background monitoring center will receive their clock-in information. If it is necessary to change the function to SOS, it is also necessary to change the function Yes, so that an alarm can be sent out in the monitoring background to deal with the SOS emergency alarm requirements in time

Heart rate detection

PT99HT  It is integrated with the function of heart rate detection, which is also an optional option. Through random heart rate detection, not only can we understand the health status and physiological characteristics of community correction personnel, but also can understand their status through some data analysis. If the heart rate is too fast for a period of time, whether there is a risk of escaping or committing a crime again, these are what the community correction managers need Data.

Waterproof design IP67

Because the smart heart rate watch needs to be worn by community correction personnel for a long time and can not be removed, including the possibility that they may be exposed to the rain when they go out, wash their hands at home, take a bath, etc. Pt99ht is a water-proof product with high level. It can swim with a wristwatch and bathe without any problem. It will not damage the watch due to contact with water.

Accessories and packaging

The highlight of pt99ht is explosion-proof, anti demolition, temperature measurement, accurate positioning, waterproof and other functions required by community correction. In addition, we also have an external charger. Through this external charger, community correction personnel can charge while wearing a wrist watch, so as not to hinder the use of the wrist watch. Even if the community correction personnel are outdoors, they can use the charger to pair wrists Charging the meter greatly facilitates the travel of community correction personnel.

Epidemic monitoring platform

In addition to a wristwatch, we also provide a community correction positioning platform. Through the web community correction management platform, managers can manage equipment, personnel, positioning, alarm, etc., and can also set various management specifications, such as file management, clock in, SOS alarm processing, and other functions. At the same time, the management platform is a group management platform, which can manage different organizations, and different organizations can have their own administrators.

Open interface

We can also open the data interface according to the needs of customers, so that it is more convenient to integrate the data of community correction platform into other systems, generate an API key through the background, generate a token after encryption, and call the platform data through token as identity card, so as to improve the security.

Security design of platform

The community correction platform is used to monitor the location, status, file information of community correction personnel, which involves the privacy of these community correction personnel. Therefore, it is particularly important to strengthen the security line. We start to encrypt the data from the device end. The platform uses SSL to encrypt the transmission channel, and web The API uses SSL / TLS channel encryption, and the background database will also lose some key data for encryption. We protect users’ factors by various means. In Europe, we have deployed some platforms in cooperation with you, and we will also comply with the most stringent data and privacy protection policies in Europe, such as gdpr.
