Pfupiso yeTL;DR:Masisitimu eCCTV ekuchengetedza makamera evanoita mabasa anoda kusarudzwa kwakanyatsonaka kwemhando dzemakamera, resolution, mhinduro dzekuchengetera, uye network infrastructure. Masisitimu akavakirwa paIP ndiwo anotonga pamusika, resolution ye4K ichiva yakajairika. Zvinhu zvikuru zvinofungwa nezvazvo zvinosanganisira kuwanda kwemakamera, zvinodiwa pakubatanidza matambo, kusarudzwa kweNVR/VMS, uye kutevedzera mitemo yekutarisa yemuno. Kuiswa kwemabhizinesi kwakajairika kunotangira pamadhora mazana mashanu kusvika zviuru zviviri zvemadhora ($500-$2,000) pakamera imwe neimwe kusanganisira kuiswa.

Nhanganyaya: Tekinoroji yeCCTV yekuchengetedzwa kwebhizinesi

Terevhizheni yeClosed-circuit (CCTV) inoreva masisitimu ekutarisa mavhidhiyo anotumira masaini kune mamonitor chaiwo kwete kuburitswa pachena. Musika weCCTV wepasi rose wakapfuura mabhiriyoni makumi mashanu nemashanu emadhora muna 2026, nemakamera eIP achitora 78% yemusika zvichienderana neMarketsandOngororo yemisikaVakondirakiti vanofanirwa kunzwisisa zvinodiwa nehunyanzvi, zvinodiwa pakuisa, uye kutevedzera mitemo pavanenge vachitsanangura masisitimu ekutarisa.

Masisitimu eCCTV emazuva ano haangogumiri pakutarisa kuchengetedzeka chete. Kuongorora kwepamusoro kunogonesa vanhu kuverenga, kuziva mapuratifomu emotokari, uye kuona kupindira kwenzvimbo. Kubatanidzwa nehurongwa hwekutonga kupinda uye masisitimu ealarm kunoita kuti pave nekuchengetedzwa kwakakwana.

Mhando dzeKamera dzeCCTV uye Mashandisirwo

Makamera eDome ekutarisa mukati

Makamera eDome ane nzvimbo yakavharirwa inovhara divi regirazi. Makamera aya anokodzera nzvimbo dzekutengesa, nzvimbo dzemahofisi, uye nzvimbo dzemahotera. MaDome anodzivirira kuparadzwa anodzivirira kukuvadzwa kusvika majoules makumi mashanu. Dhizaini yakavharwa inodzivirira kuungana kweguruva uye kuedza kudzvanywa.

Makamera eBullets ekudzivirira denderedzwa

Makamera ane mabara anopa dziviriro inooneka nedzimba dzisingapindi mamiriro ekunze kuti dziiswe panze. Makamera aya anowanzova nehurefu hwakareba hwekuona kure. Makamuri ane IP67 anodzivirira kubva muguruva nekunyudzwa mumvura. Magirazi eIR akabatanidzwa anogonesa kuona husiku kusvika pamamita zana zvichienderana nezvinodiwa zvemuenzaniso.

Makamera ePTZ Ekutarisa Nekushanda

Makamera ePan-tilt-zoom anopa kufukidza kwemadhigirii 360 ane kugona kwe optical zoom kubva pa20x kusvika ku40x. Vashandi vekuchengetedza vanodzora nzvimbo yekamera kuti vatevere vanhu. Maficha e auto-tracking anotevera otomatiki zvinhu zvinofamba mukati menzvimbo dzakatarwa. Makamera ePTZ anoda kuiswa kwakaoma uye mapurogiramu kupfuura makamera akagadzirwa.

Zvinodiwa paNetwork Infrastructure neBandwidth

Kuchinja kwePoE uye Kutumira Simba

Simba pamusoro peEthernet (PoE) rinotumira data uye simba remagetsi kuburikidza netambo imwe chete yeCat5e/Cat6. IEEE 802.3af inopa 15.4W pachiteshi chimwe nechimwe, inokwana makamera akajairwa. IEEE 802.3at (PoE+) inopa 30W kumakamera ePTZ nemaheater.IEEE 802.3bt standardinogonesa 60-90W kumashandisirwo ane simba guru.

Kuverenga kwebandwidth uye kuchengetedza

Zvinodiwa pakushandisa bandwidth zvinoenderana ne resolution, frame rate, uye compression codec. Kudzvanywa kweH.265 kunoderedza bandwidth ne50% zvichienzaniswa neH.264. Kamera ye4MP pa15fps inoda angangoita 4-6 Mbps. Maswichi enetwork anoda kugona kwakakwana kwebackplane kuti abate ma aggregated camera streams pasina kurasikirwa nemapaketi.

Maitiro Ekuchengetedza Mavhidhiyo Uye Kuachengeta

Mavhidhiyo eNetwork recorders (NVR) uye masisitimu ekutarisira mavhidhiyo (VMS) anochengetwa kuti aonekwe kuti humbowo hwawanikwa. Nguva dzekuchengetedza dzinowanzo tora mazuva makumi matatu kusvika makumi mapfumbamwe zvichienderana nezvinodiwa nemutemo uye kuongororwa kwenjodzi. Kuchengetedza makadhi eSD kunopa rutsigiro panguva yekudzimwa kwenetwork. Kuchengetedza kwegore kunopa mukana wekusadzoserwa kwedata panzvimbo imwe chete asi kunoda bandwidth yakakura yekurodha.

Maitiro Akanakisisa Ekuisa Makondirakiti

Kuiswa kwekamera kunotevera mutemo wemamita makumi maviri: isa makamera mukati memamita makumi maviri kubva panzvimbo dzakatariswa kuti uonekwe pachiso.Chinyorwa cheNEC 725inodzora kuiswa kwetambo dzine simba shoma dzemagetsi ekuchengetedza. Zviyero zvekuzadza maconduit hazvifanirwe kudarika 40% kuti kupisa kuparare zvakanaka. Kudzika pasi uye kudzivirira kukwira kwemvura kunodzivirira kukuvara kwemidziyo kubva mumadutu emagetsi.

Mibvunzo Inowanzo bvunzwa

Ndeupi musiyano uripo pakati peNVR neDVR systems?

NVR (Network Video Recorder) inoshandisa ma IP camera streams edhijitari kuburikidza ne network connections. DVR (Digital Video Recorder) inoshandura ma analog camera signals kuita digital format. NVR systems dzinopa kugona kwepamusoro-soro, nyore scalability, uye mabhenefiti ekushandisa kure. Nzvimbo dzemazuva ano dzinonyanya kushandisa NVR technology.

Masisitimu eCCTV anoda nzvimbo yekuchengetera zvinhu yakawanda sei?

Zvinodiwa pakuchengetedza verenga uchishandisa fomura iyi: Kuwanda kweKamera × Bitrate × Maawa Ekurekodha × Mazuva Ekuchengetedza. Kamera ye4MP inorekodha nguva dzose pa4Mbps inoda inenge 42GB pazuva. Kuchengetedza kwemakamera gumi nematanhatu kwemazuva makumi matatu kunoda kugona kwekuchengetedza kwe20TB. Kurekodha kwakavakirwa pakufamba kunoderedza zvinodiwa pakuchengetedza ne40-60%.

Ndedzipi tambo dzinokurudzirwa pakuisa makamera eIP?

Cable yeCat5e inotsigira kumhanya kwekhamera kusvika pamamita zana pa100Mbps. Cable yeCat6 inogonesa 1Gbps kubatanidza kune makamera ane masensa akawanda uye 4K. Kuisa kunze kunoda tambo yeUV-rated kana yekuviga zvakananga ine dziviriro yakakodzera.TIA-568 muyeroinotsanangura zvinodiwa zvetambo dzakarongeka dzekuisa mafekitori.

Makamera eCCTV anoshanda here asina internet?

Masisitimu eNVR emunharaunda anoshanda ega pasina internet. Kubatana neinternet kunoita kuti uone uri kure, zviziviso zvefoni, uye mabasa ekuchengetedza data kubva kucloud. Masisitimu akazvimirira anoramba achirekodha kana internet yadzima. Kutarisa kunze kwewebsite uye zviziviso zvekusundidzira zvinoda kubatana nenetwork.

Ndezvipi zvinhu zvinoita kuti kamera ishande zvakanaka?

Zvidimbu zvishoma zvechiedza zvinoratidza mwero wechiedza unodiwa pamifananidzo inoshandiswa. Makamera ane mavara anowanzoda 0.1-0.5 lux kuti ashande husiku. Magirazi eIR anopa chiedza chisingaonekwe cheinfrared chekuona husiku hwemonochrome. Tekinoroji yeWide dynamic range (WDR) inobata mamiriro akaoma emwenje wekumashure. Makamera ane nyeredzi anowana mifananidzo yemavara murima rakati wandei (0.001 lux).

Mhedziso: Kutsanangura Masisitimu ECCTV Anoshanda

Magadzirirwo eCCTV system anoda kunzwisisa matekinoroji emakamera, network infrastructure, uye zvinodiwa pakuchengetedza. Masisitimu akavakirwa paIP ane resolution ye4MP kana yepamusoro anopa humbowo hwepamusoro hwezviitiko zvekuchengetedza. Kugadzirwa kwenetwork kwakakodzera kunoita kuti vhidhiyo itumirwe zvakanaka pasina zvipingamupinyi zvebandwidth. Vakondirakiti vanofanirwa kuyera zvirambidzo zvebhajeti yevatengi nezvinodiwa pakushanda uku vachiona kuti mitemo yekutarisa yemuno nemitemo yekuchengetedzwa kweruzivo rwevanhu yatevedzerwa.
