Hello kowa da kowa!
Ina haɓaka firmware don kyamarorin sa ido na bidiyo don ayyukan b2b da b2c, da waɗanda ke shiga cikin ayyukan sa ido na bidiyo na tarayya.
Na rubuta game da yadda muka fara .
Tun daga wannan lokacin, abubuwa da yawa sun canza - mun fara tallafawa har ma da ƙarin kwakwalwan kwamfuta, misali, irin su mstar da fullhan, mun sadu da yin abokai da adadi mai yawa na masana'antun kyamarar IP na waje da na gida.
Gabaɗaya, masu haɓaka kyamara sukan zo mana don nuna sabbin kayan aiki, tattauna abubuwan fasaha na firmware ko tsarin samarwa.
Amma, kamar yadda ko da yaushe, wani lokacin m mutane zo - suna kawo gaskiya na kasar Sin kayayyakin da ingancin da ba a yarda da su tare da firmware cike da ramuka, da kuma gaggawa rufaffiyar alama na wani uku-rate ma'aikata, amma a lokaci guda da'awar cewa sun ɓullo da kome da kansu: duka biyu. da circuitry da firmware, kuma sun kasance gaba ɗaya samfurin Rashanci.
A yau zan ba ku labarin wasu daga cikin waɗannan mutanen. A gaskiya, ni ba mai goyon bayan bulala na jama'a na rashin kulawa "masu maye gurbin shigo da kaya" - yawanci na yanke shawarar cewa ba mu da sha'awar dangantaka da irin waɗannan kamfanoni, kuma a wannan lokacin mun rabu da su.
Amma, duk da haka, yau ina karanta labarai a Facebook ina shan kofi na safe, na kusa zubar da shi bayan karantawa cewa reshen Rusnano, kamfanin ELVIS-NeoTek, tare da Rostec, za su samar da dubun dubatar kyamarori ga makarantu.
A ƙasa yanke akwai cikakkun bayanai na yadda muka gwada su.
Haka ne, a - waɗannan su ne mutanen da suka kawo mini arha da kuma mummunan China, a ƙarƙashin sunan ci gaban kansu.
Don haka, bari mu dubi gaskiyar: Sun kawo mana kyamarar “VisorJet Smart Bullet”, daga na gida - tana da akwati da takardar karɓar QC (:-D), a ciki akwai kyamarar ƙirar Sinawa ta yau da kullun dangane da Hisilicon 3516 chipset.
Bayan yin juji na firmware, da sauri ya bayyana a fili cewa ainihin ƙera kyamara da firmware wani kamfani ne "Brovotech", wanda ya ƙware wajen samar da kyamarorin IP na musamman. Na dabam, na yi fushi da sunan wannan ofishin na biyu "» karya ce ta sunan kamfanin Ezviz, 'yar b2c na ɗaya daga cikin shugabannin duniya Hikvision. Hmm komai yana cikin mafi kyawun al'adun Abibas da Nokla.
Duk abin da ke cikin firmware ya zama daidaitaccen, mara fa'ida cikin Sinanci:

Daga masana'anta na gida muna ganin fayil ɗin elvis.jpg - ba mara kyau ba, amma tare da kuskure a cikin sunan kamfanin - yin hukunci ta wurin ana kiran su "elvees".
bvipcam yana da alhakin aikin kyamara - babban aikace-aikacen da ke aiki tare da rafukan A/V kuma sabar cibiyar sadarwa ce.
Yanzu game da ramuka da bayan gida:
1. Ƙofar baya a cikin bvipcam abu ne mai sauƙi: strcmp (kalmar sirri," 20140808") && strcmp (sunan mai amfani, "bvtech"). Ba a kashe shi, kuma yana aiki akan tashar jiragen ruwa mara naƙasasshe 6000
2. A cikin /etc/inuwa akwai tushen kalmar sirri da kuma bude tashar telnet. Ba MacBook mafi ƙarfi ya tilasta wannan kalmar sirri cikin ƙasa da awa ɗaya ba.
3. Kamara na iya aika duk adana kalmomin shiga ta hanyar dubawar sarrafawa a cikin bayyanannen rubutu. Wato, ta hanyar shiga kyamara ta amfani da bayanan shiga bayan gida daga (1), zaka iya gano kalmar sirrin duk masu amfani cikin sauki.
Na yi duk waɗannan magudin da kaina - hukuncin a bayyane yake. Firmware na China na uku, wanda ko da ba za a iya amfani da shi a cikin manyan ayyuka ba.
Af, na same shi kadan daga baya - a ciki sun yi aiki mai zurfi a kan nazarin ramuka a cikin kyamarori daga brovotech. Hmmm.
Dangane da sakamakon gwajin, mun rubuta ƙarshe zuwa ELVIS-NeoTek tare da duk abubuwan da aka gano. A cikin mayar da martani, mun sami babbar amsa daga ELVIS-NeoTek: "Furware don kyamarorinmu ya dogara ne akan Linux SDK daga mai sarrafa HiSilicon. Domin Ana amfani da waɗannan masu sarrafawa a cikin kyamarorinmu. A lokaci guda kuma, an samar da namu software a saman wannan SDK, wanda ke da alhakin hulɗar kyamara ta hanyar amfani da ka'idojin musayar bayanai. Yana da wuya ƙwararrun masu gwajin su gano, tun da ba mu samar da tushen damar yin amfani da kyamarori ba.
Kuma idan aka tantance daga waje, za a iya samar da ra'ayi mara kyau. Idan ya cancanta, muna shirye mu nuna wa ƙwararrun ku duk tsarin samarwa da firmware na kyamarori a cikin samarwa. Ciki har da nuna wani ɓangare na lambobin tushen firmware."
A zahiri, babu wanda ya nuna lambar tushe.
Na yanke shawarar ba zan ƙara yin aiki da su ba. Yanzu, bayan shekaru biyu, shirin da kamfanin Elvees ya yi na kera kyamarori na kasar Sin masu arha tare da firmware na kasar Sin mai arha a karkashin sunan ci gaban Rasha ya sami aikace-aikacen su.
Yanzu na je gidan yanar gizon su na gano cewa sun sabunta layin kyamarar su kuma ba ya kama da Brovotech. Wow, watakila mutanen sun gane kuma sun gyara kansu - sun yi duk abin da kansu, wannan lokacin da gaskiya, ba tare da leaky firmware ba.
Amma, kash, kwatanta mafi sauƙi "Rasha" kamara ya ba da sakamako.
Don haka, hadu da asali: kyamarori daga mizanin mai siyar da ba a san su ba.
Ta yaya wannan matakin ya fi brovotech kyau? Daga ra'ayi na tsaro, mafi mahimmanci, babu wani abu - bayani mai arha don siye.
Kawai kalli hoton hotunan yanar gizo na mizani da kyamarori na ELVIS-NeoTek - ba za a yi shakka ba: kyamarori na "Rasha" VisorJet sune kyamarorin kyamarori masu nisa. Ba wai kawai hotuna na musaya na yanar gizo sun dace ba, har ma da tsoho IP 192.168.5.190 da zane-zane na kyamara. Ko da kalmar sirri ta tsoho tana kama da: ms1234 vs en123456 don clone.
A ƙarshe, zan iya cewa ni uba ne, ina da yara a makaranta kuma ina adawa da yin amfani da kyamarori na kasar Sin masu leken asiri na kasar Sin, tare da Trojans da bayan gida a cikin iliminsu.
