Featuring an RFID patrol function, it can provide full-process support for the entire patrol workflow when paired with the back-end server. The whole device adopts the classic two-way radio layout with screen/navigation keypad interaction, a high-strength two-tone casing, a rugged alloy frame, and high-level waterproof sealing, ensuring durable operation in harsh environments. The DH452 will deliver a comprehensive digital communication and patrol management experience for users, and provide solid support for improving management efficiency.

It supports digital conventional standards (PDR/DMR), delivers high-quality digital conventional voice services, meets the high-standard requirements for work communication, and can quickly respond to calls from professional customers anytime and anywhere. Compared with traditional analog technology, the dual-slot technology can provide double channel capacity, thus greatly alleviating the growing pressure of spectrum resource shortage.
Digital-analog compatibility to protect user investment: In addition to the digital conventional mode, it also supports the analog conventional mode, enabling it to operate in the user's existing network environment with stronger applicability. This feature protects the existing investment of professional customers and supports the smooth transition of professional customer networks.
Excellent RF performance: With carefully matched and optimized hardware circuits combined with an integrally formed long helical antenna, the whole device boasts outstanding RF performance and higher receiving sensitivity, enabling longer-distance intercom communication connections.
RFID patrol support: Built-in with an RFID patrol card reader, it supports 13.56MHz RFID international and domestic standards, and can contactlessly read standard-compliant passive RFID tags. The patrol data stored in the tags, together with the device's local data, will be wirelessly uploaded to the back-end server in one go, to realize remote patrol management on the backend.
Rich service functions: In addition to supporting standard voice services and data services, it can also provide a wealth of supplementary services such as lone worker protection and radio status check. According to user demands, service functions can be continuously expanded via firmware upgrade in the later stage to improve the terminal's practicality and help users carry out their work more efficiently.
Rugged and reliable quality: The whole device meets the IP65 protection rating and is suitable for outdoor work. Multiple indicators including impact resistance, vibration resistance, and solar radiation resistance meet high-reliability standards, making it competent for various harsh working environments.
