Buku Lothandizira Kuyika CCTV M'magalimoto
Kufunika kwa chitetezo cha maulendo ndi zikalata tsopano kukukulirakulira. Sikuti kwa makampani amalonda okha monga zoyendera, mabungwe oyendera, mabasi, ndi ma taxi apaintaneti, komanso ma CCTV a m'galimoto amayikidwanso m'magalimoto achinsinsi kuti aziyang'anira kanyumba, kulemba zochitika pamsewu, ndikupereka umboni pakagwa ngozi. Komabe, kukhazikitsa CCTV ya m'galimoto sikufanana ndi kukhazikitsa CCTV kunyumba kapena kuofesi. Pali zovuta zapadera monga kugwedezeka, kusintha kwa kutentha, malire a mphamvu, ndi kuyika kamera komwe sikusokoneza chitetezo choyendetsa. Nkhaniyi ikufotokoza za kalozera wokhazikitsa CCTV ya m'galimoto mwachisawawa, mosamala, komanso mwaukhondo.
1. Dziwani Zosowa ndi Cholinga cha Kukhazikitsa
Gawo loyamba ndikudziwa cholinga chachikulu cha kukhazikitsa. Kodi mukufuna kujambula momwe zinthu zilili m'nyumba, kuyang'anira momwe dalaivala amagwirira ntchito, kujambula zochitika za okwera, kapena kujambula momwe zinthu zilili pamsewu (monga kamera yojambulira)? Cholinga ichi chidzakhudza mtundu wa kamera, kuchuluka kwa njira, ndi zomwe zimafotokozera za chojambulira.
Pa magalimoto a mabanja, makamera 1-2 nthawi zambiri amakhala okwanira: imodzi yoyang'ana kutsogolo (msewu) ndi ina yoyang'ana kanyumba. Pa magalimoto ogwirira ntchito (magalimoto oyendera, malole, mabasi), makamera 4-8 nthawi zambiri amayikidwa: kutsogolo, kumbuyo, kumanzere ndi kumanja, ndi malo angapo m'kanyumba. Komanso, ganizirani ngati mukufuna mawu, GPS, kulumikizana kwa 4G kuti muwonetsetse kutali, kapena kusungirako komweko.
2. Kusankha Galimoto Yoyenera ya CCTV
Mosiyana ndi makina a DVR apakhomo, magalimoto amagwiritsa ntchito bwino DVR yam'manja (MDVR) kapena NVR yam'manja, yomwe idapangidwa kuti ipirire kugwedezeka komanso kuyendetsa mphamvu zamagalimoto. Zinthu zotsatirazi nthawi zambiri zimafunika:
– Kamera: sankhani kamera yapadera ya galimoto (kamera yam'manja) yomwe siigwedezeka ndi mantha, imawona usiku, komanso imawonera molingana ndi zosowa zanu.
– Chojambulira (MDVR/NVR): onetsetsani kuti chikuthandizira chiwerengero cha makamera omwe mukuyika (njira 4/8/16), chili ndi malo osungira (SD/HDD/SSD), ndipo chikuthandizira makanema abwino.
– Zingwe ndi zolumikizira: gwiritsani ntchito zingwe zabwino zokhala ndi zolumikizira zokhoma kuti zisamasuke chifukwa cha kugwedezeka.
– Kusungirako: Pa magalimoto, khadi la SSD kapena SD lomwe limakhala lolimba kwambiri limalimbikitsidwa. Ma HDD wamba ali pachiwopsezo cha kuwonongeka chifukwa cha kugwedezeka.
- Zowonjezera zamagetsi: ma fuse, ma relay ngati pakufunika, ndi zida zotetezera magetsi.
Ngati mukufuna kuwunika nthawi yeniyeni, sankhani MDVR yomwe imathandizira gawo la 4G ndi pulogalamu yowunikira. Kuti mudziwe komwe kuli komanso momwe zinthu zilili, sankhani chipangizo chokhala ndi GPS.
3. Dziwani Malo Oyikira Kamera
Kuyika kwa kamera kumatsimikizira ubwino wa kujambula ndi kugwira ntchito bwino kwa kuyang'anira. Mfundo yaikulu ndi yakuti: kamera iyenera kukhala yokhazikika, yosalepheretsa dalaivala kuona, komanso yosafikirika mosavuta kuti isokonezedwe.
Malangizo okhudza malo:
– Kamera yakutsogolo (msewu): yoyikidwa pamwamba pa galasi lakutsogolo (pafupi ndi galasi lakumbuyo), yoyang'ana molunjika pamsewu.
– Kamera ya kabati: yoyikidwa pakati kapena pafupi ndi denga, moyang'anizana ndi malo okwera.
– Kamera yakumbuyo: ikhoza kukhala pawindo lakumbuyo (mkati) kapena kunja pafupi ndi layisensi (kunja), kutengera zosowa zanu.
– Makamera am'mbali: nthawi zambiri amaikidwa pagalasi lowonera kumbuyo kapena mzati wa galimoto kuti achepetse malo osawoneka bwino.
Onetsetsani kuti ngodyayo siili "mmwamba" kapena "pansi kwambiri." Yesani kuwunika musanayike kokhazikika.
4. Kukonzekera Njira Zoyendetsera Ma Cable Kuti Zikhale Zoyera Komanso Zotetezeka
Kuyera ndi chitetezo cha kukhazikitsa n'kofunika kwambiri pa moyo wa dongosololi. Zingwe zomwe zimasiyidwa zitapachikidwa zimatha kusokoneza madalaivala, kugwidwa ndi okwera, kapena kuwonongeka mwachangu.

- Gwiritsani ntchito bwino mizere ya fakitale: mipata ya denga, zipilala za A/B/C, pansi pa makapeti, kapena mapanelo amkati.
– Pewani malo otentha (pafupi ndi injini) ndi malo oyenda (zipilala za mipando, ma pedal).
- Gwiritsani ntchito zingwe zolumikizira, chokulunga chozungulira, ndi tepi ya nsalu kuti ikhale chete ndikuletsa kuti isatuluke mosavuta.
– Lembani mawaya kuti musavutike kukonza (Front Cam1, Cabin Cam2, ndi zina zotero).
Pa magalimoto amalonda, njira ya chingwe nthawi zambiri imakokedwa kudzera padenga ndikutsikira pansi pa dashboard kapena pansi pa mpando pomwe MDVR imayikidwa.
5. Kulumikiza kwa Mphamvu: Kotetezeka, Kokhazikika, Ndipo Sikugwira Ntchito Yotulutsa Batri
Magwero amagetsi a magalimoto nthawi zambiri amakhala 12V (magalimoto) kapena 24V (malole/mabasi). Onetsetsani kuti chipangizochi chikuchirikiza ma voltage awa kapena gwiritsani ntchito chosinthira cha DC-DC choyenera.
Mfundo zachitetezo chamagetsi:
– Tengani mphamvu kuchokera ku chingwe cha ACC/ignition ngati mukufuna kuti CCTV iziyatsa injini ikayaka.
- Ngati mukufuna kupitiriza kujambula pamene mukuimika galimoto, muyenera "kuimika galimoto" yokhala ndi njira yochepetsera mphamvu yamagetsi kuti batire isathe.
- Ikani fuse pafupi momwe mungathere ndi malo ogwiritsira ntchito mphamvu.
- Onetsetsani kuti nthaka (pansi) ndi yolimba komanso yoyera kuti isayambitse phokoso kapena kuyambitsanso chipangizocho pafupipafupi.
Musamangolumikiza zingwe ku batire popanda chitetezo. Kukwera kwa mphamvu yamagetsi mukayiyambitsa kungawononge chipangizocho mwachangu ngati sichitetezedwa.
6. Kukhazikitsa kwa MDVR/NVR: Malo ndi Mpweya wopumira
Ikani chojambulira pamalo omwe:
– Kubisika komanso kosavuta kufikako (kumachepetsa chiopsezo cha kuwonongedwa/kuba).
- Khalani ndi mpweya wokwanira kuti musapse kwambiri.
- Ntchito yosavuta kupeza (kusintha SD/SSD) koma si yowonekera bwino.
Malo odziwika bwino: pansi pa mpando, kumbuyo kwa dashboard, kapena m'chipinda chodziwika bwino m'galimoto yothandiza. Gwiritsani ntchito bulaketi yolimba ndi mabawuti olimba, chifukwa kugwedezeka kwa msewu kumatha kumasula chojambulira ngati chingolumikizidwa.
7. Kapangidwe ka Dongosolo: Kusasinthika, Kuchuluka kwa Chimango, ndi Kusungirako
