HY-4 Smart Lock nigikorwa cyo hejuru cyumutekano wo murugo kirimo nikel nziza irangiza kandi yubatswe na zinc alloy kubaka kugirango ikoreshwe igihe kirekire. Umwanya w'imbere upima 161.5 × 73.3 × 30 mm, naho inyuma yinyuma ni 168.5 × 72.5 × 51.2 mm, ibereye inzugi zisanzwe zimbaho ​​nicyuma zifite ubugari bwa 35mm kugeza 55mm. Ifite icyuma gikoresha urutoki rwa semiconductor, rushyigikira intoki zigera kuri 50 hamwe n’ikigereranyo cyo kwakirwa kiri munsi ya 0.001%, gitanga ibyoroshye ndetse n’umutekano wongerewe.

HY-4 yemerera ijambo ryibanga kwinjiza imibare 6 kugeza kuri 16, irashobora gufata ijambo ryibanga rigera ku 100, hamwe nimiterere ya kode yuburyo bwo kongeramo uburinzi. Usibye urufunguzo rwo gukoraho, ruzana urufunguzo rwibikoresho bibiri nkibisubizo byihutirwa. Ikoreshwa na bateri enye AA, ifite igihe cyamezi hafi 10. Yubahirije ibipimo bya ANSI BHMA A156.25, ikora mubushyuhe bwa -35 ℃ kugeza kuri + 70 ℃, bigatuma ihuza nibidukikije bitandukanye. HY-4 ifungura vuba mumasegonda 1 gusa, itanga uburambe bwumukoresha, bworoshye, kandi bunoze.
