Momwe mungasankhire DVR pagalimoto: ndemanga ndi makanema
DVRs akhala akugwiritsidwa ntchito ndi oyendetsa ambiri, chipangizo ichi wakhala mbali yofunika kwambiri mu kanyumba. Chifukwa chake, mutha kulemba zonse zomwe zimakuchitikirani mukuyendetsa galimoto, ndipo pakachitika ngozi yapamsewu, mutha kutsimikizira kuti ndinu osalakwa. Mukapita ku sitolo iliyonse kapena kupita ku sitolo ya pa intaneti, mudzawona mitundu yambiri ya zipangizozi, zomwe zimasiyana wina ndi mzake potengera mtengo ndi makhalidwe awo.
Momwe mungasankhire DVR yabwino yagalimoto, ndi zinthu ziti zomwe muyenera kuziganizira? Takambirana kale nkhaniyi patsamba lathu la Vodi.su, pofotokoza mitundu yotchuka ya olembetsa mu 2015.
Kwenikweni, DVR ndi kamera yaying'ono yomwe imayikidwa pazenera, koma m'zaka zaposachedwa ntchitoyi yakula kwambiri, ndipo khalidwe lojambulira likuyenda bwino, ndipo izi sizosadabwitsa - onani momwe mafoni a m'manja afika patali zaka 10 - kuchokera ku bulky. ma monoblocks okhala ndi tinyanga ndi mphamvu zochepa , ku mafoni owonda kwambiri, omwe ndi makompyuta ang'onoang'ono athunthu.
Zomwezo zinachitikanso ndi zojambulira makanema. Komabe, kodi ntchito zonsezi ndi zofunika pamoyo weniweni? Tiyeni tikambirane mwatsatanetsatane.
Kujambula khalidwe ndiye chizindikiro chachikulu.
Mawonekedwe otsatirawa akugwiritsidwa ntchito pano:
- Ma pixel a VGA - 640x480, mawonekedwe achikale, mu chithunzi chotere mutha kuwona msewu, magalimoto kutsogolo, mseu, koma simungathe kusiyanitsa mwatsatanetsatane: simungathe kudziwa manambala, ngakhale mitundu. magalimoto ena, kupatulapo mitundu imasokonekera kwambiri;
- HD - mapikiselo apamwamba a 1280x720, khalidwe lojambulira ndilobwino kangapo, mavidiyo oterewa amatha kuwonedwa pawindo lalikulu, ngakhale zazing'ono - manambala a galimoto - amatha kuwerengedwa pafupi kwambiri, kukongola kudzakhalaponso;
- Full-HD - 1920x1080 pixels - chithunzi chabwino kwambiri, mutha kuwona pafupifupi tsatanetsatane, mpaka manambala agalimoto omwe sali kutali kwambiri;
- Super-HD - 2304 × 1296 - chisankho chabwino kwambiri pakali pano, makanema otere amatha kuwonedwa pa TV yayikulu, khalidweli lidzakusangalatsani, pafupifupi zonse zofunika zidzawoneka kwa inu: mapepala alayisensi, zizindikiro za pamsewu ndi zizindikiro. , nkhope za anthu ndi zina zotero.
Ndiye kuti, ngati mukufuna kuti olembetsa achite bwino ntchito yake yayikulu, sankhani kuchokera pamitundu iwiri yomaliza.
Komabe, kusamvana ndi chimodzi mwazinthu zomwe zimakhudza mtundu wa kujambula, ndipo gawo ngati liwiro lojambulira ndilofunikanso chimodzimodzi, limayesedwa mu mafelemu pamphindikati. Malinga ndi miyezo yamakono, liwiro lojambulira liyenera kukhala mafelemu osachepera 25 pamphindikati, pali zitsanzo zapamwamba kwambiri zomwe zimatha kupanga mafelemu 30 pamphindikati.
Kanemayo ndi wapamwamba kwambiri, m'pamenenso amatenga malo ambiri pa memori khadi. Palinso zitsanzo zomwe mungathe kusankha pamanja liwiro lojambulira, mwachitsanzo, ngati khadi yokumbukira idapangidwira 8 kapena 16 GB, ndiye kuti ndi bwino kusankha liwiro lotsika, ngakhale ojambulira makanema ambiri apakati komanso apamwamba amatha makhadi othandizira pa 36, 64 ngakhale 128 kapena 256 Gigabyte.
Kuti mugwirizane ndi zambiri pa memori khadi, muyenera kusankha registrar yoyenera malinga ndi njira yopondereza mafayilo (encoder, codec, decoder).
Mafayilo ophatikizika:
- MJPEG - mawonekedwe achikale otengera mawonekedwe-ndi-frame psinjika, kanema wotere amatenga malo ambiri, phokoso limasungidwa padera;
- MPEG4 - kukanikiza munthawi yomweyo ma audio ndi makanema, makanema amatenga malo ochepera 10;
- H.264 ndi mtundu wapamwamba kwambiri, umatenga theka la danga kuposa lapitalo, ndipo pambali pake, pali mtundu wabwinoko komanso kutulutsa mawu.
Pali akamagwiritsa ngati MOV kapena avi, kanema owona mu chikwatu olembedwa awa akamagwiritsa ndi chizindikiro chonchi: video.mov kapena video.avi. Palinso mawonekedwe apadera omwe amagwiritsidwa ntchito ndi opanga payekha. Mawonekedwe a VisionDrive amadziwonetsa bwino, omwe adapangidwa mwapadera kuti ajambule kanema poyenda. Kusewera izo, muyenera kukopera wapadera TV wosewera mpira pulogalamu pa kompyuta.
Mfundo ina yofunika ndi mode usiku. M'malo mwake, mawonekedwe ausiku ndiye vuto la wolemba aliyense. M'misewu yamzindawu yowunikiridwa, kanemayo amatuluka ngakhale pang'ono kapena pang'ono mwapamwamba kwambiri, koma kunja kwa mzinda, kumene misewu imakhala yosayatsa, zimakhala zovuta kwambiri kuti muwone kalikonse. Kuti athetse vutoli, opanga ambiri amayika kuwunikira kwa infuraredi, koma kuchokera pazomwe takumana nazo tidzanena kuti sizothandiza.
Chabwino, parameter ina yofunika kwambiri ndi ngodya yowonera. Ngodya nthawi zambiri imayesedwa mwa diagonally ndipo imatha kuyambira madigiri 60 mpaka 170. Timatcha kusiyana koyenera - madigiri 90-140. Ndi mbali yowonera iyi yomwe itilola kulingalira magulu oyandikana nawo. Ngati ngodyayo ndi yopapatiza kwambiri, ndiye kuti simudzawona, mwachitsanzo, magalimoto m'misewu yoyandikana nayo, koma ngati ngodyayo iposa madigiri 140, ndiye kuti chithunzicho chimasokonekera kwambiri chifukwa cha zotsatira za fisheye.
Kuyika njira, kutha kutembenuza madigiri a 180 - pali olembetsa omwe amatha kutumizidwa motetezeka mbali zosiyanasiyana kuti alembe zokambirana ndi woyang'anira apolisi apamsewu. Palinso omwe amamangidwa mwamphamvu pa tripod.
Sensa yoyenda ndi chinthu chothandiza kwambiri, chojambuliracho chimangodzuka kuchokera kumayendedwe ogona atangowona kusuntha kulikonse m'munda wowonera.
G-Sensor kapena shock sensor - foda yapadera yokhazikika imayikidwa pa memori khadi, momwe kanema wojambulidwa pakagwa mwadzidzidzi amasungidwa. Mwachitsanzo, ngati mutagundidwa kuchokera kumbuyo, kapena munakakamizika kuthyoka kwambiri, kanemayo idzasungidwa mufoda iyi ndipo sichidzachotsedwa panthawi yojambula.
GPS ndi chowonjezera chothandiza kwambiri. Kanemayo amalemba liwiro lakuyenda komanso tsiku lomwe likubwera. Kenako, mukawonera kanema pakompyuta, mutha kuyigwirizanitsa ndi mamapu a Google, ndipo liwiro lenileni lakuyenda likuwonetsedwa pagawo lililonse.
Samalaninso kukula kwa chiwonetsero, kuchuluka kwa batri, mawonekedwe azithunzi, kuyera koyera, zosefera (kuwunika ma radiation osafunikira).
Makanema ojambulira ochulukirapo kapena ocheperako amawononga ndalama zosachepera ma ruble 4.
