Kufotokozera
Ma Microphone a Mverani Kupyolera mu Walls amatha kulandira ndikujambulitsa mawu a analogi (mawu amunthu, mapazi, mawu ena).Chifukwa cha kukhazikitsidwa kwa chowunikira chochepa chaphokoso cha DSP ndi zida zokulitsa, chizindikirocho chimatengedwa ndi masensa akumanzere ndi kumanja odziyimira pawokha kutsogolo, ndikutulutsa pambuyo pakuchotsedwa ndi gawo lowongolera kumbuyo kumbuyo, kotero makinawo amatengedwa. amatha kuzindikira phokoso laling'ono kwambiri.
Dongosolo limatha kunyamula phokosokudzerakumanga makoma, denga, pansi, ndi zina zotero. Sensa yakunja imagwirizanitsidwa ndi amplifier ya audio yomwe imapereka mphamvu zowonongeka kumanzere ndi kumanja, komanso kujambula kunja kwa USB flash drive.Ndiwo mtsogoleri wamtundu womwewo wazinthu popereka zolondola, zomveka komanso zomveka bwino zomvetsera ndikujambula chaka ndi nthawi.Zimamveka kudzera m'nyumba monga makoma, madenga ndi pansi, monga momwe amachitira anthu ogwidwa.
ItSizingagwiritsidwe ntchito ngati zida zapadera zowunikira mwachangu, komanso apolisi ankhondo, kufufuza kwaupandu, dipatimenti yofufuza zaukadaulo ndi zotsutsana ndi zinthu zofunika.
Mawonekedwe
- Kukonzekera kwamphamvu kwamawu a DSP opangidwa ndi algorithm, kuti muwonetsetse kumveka bwino kwamawu.
- Katswiri wamakasitomala ogawa ma audio sensor, kugwedezeka kwa sensor sensor kudzera paphokoso lotsika kwambiri la amplifier + DSP processing, ngakhale siginecha yofooka kwambiri imathanso kumveka.
- Ndi masensa omvera aukadaulo, tchanelo 1 kapena tchanelo 2, kapena kumvera onse.
- Pambuyo pakutulutsa kwa DSP, njira ziwiri zitha kujambulidwa nthawi imodzi.
- Monitoring mode: mawaya mahedifoni, opanda zingwe Bluetooth headset, kujambula.
- Katswiri komanso makonda okhudza kukhudza + kugwedeza.

Chiyambi cha Kampani
Mu 2008, Beijing Hewei Yongtai Technology Co., LTD inakhazikitsidwa ku Beijing.Kuyang'ana pa chitukuko ndi ntchito ya zida zapadera zotetezera, makamaka zimatumikira malamulo a chitetezo cha anthu, apolisi okhala ndi zida, asilikali, miyambo ndi madipatimenti ena a chitetezo cha dziko.
Mu 2010, Jiangsu Hewei Police Equipment Manufacturing Co., LTD inakhazikitsidwa ku Guannan.Kuphimba malo okwana 9000 sqm ya msonkhano ndi nyumba yomanga maofesi, cholinga chake ndi kumanga kafukufuku wa zida zachitetezo chapadera ndi chitukuko ku China.
Mu 2015, wapolisi-wapolisi Research ndi pakati chitukuko unakhazikitsidwa mu Shenzhen.Focus pa chitukuko cha zida chitetezo chapadera, wapanga mitundu yoposa 200 ya zida akatswiri chitetezo.
Ziwonetsero Zakunja
Beijing Heweiyongtai Sci & Tech Co., Ltd. ndi Wotsogola Wotsogola wa EOD ndi Security Solutions.Ogwira ntchito athu onse ndi akatswiri oyenerera aukadaulo ndi oyang'anira kuti akupatseni ntchito yokhutitsidwa.
Zogulitsa zonse zili ndi malipoti a mayeso amtundu wa akatswiri ndi ziphaso zololeza, kotero chonde dziwani kuti mwayitanitsa malonda athu.
Kuwongolera kokhazikika kuti zitsimikizire moyo wautali wazinthu zomwe zimagwiritsidwa ntchito komanso wogwiritsa ntchito akugwira ntchito motetezeka.
Ndili ndi zaka zopitilira 10 zamakampani a EOD, zida zothana ndi uchigawenga, chida chanzeru, ndi zina zambiri.
Tatumikira mwaukadaulo makasitomala opitilira 60 padziko lonse lapansi.
Palibe MOQ pazinthu zambiri, kutumiza mwachangu kwazinthu zosinthidwa makonda.
