Yog vim li cas Wi-nkaus tsis Wireless rau lub tswb

Wireless ua rau txhim kho alarms yooj yim, tsis yog vim wireless lub sensors siv xov tooj cua zaus (RF) sib txuas lus, tabsis vim tias nws yeej tsis nyob ntawm tej. Wireless tswb sensors cov roj teeb powered thiab yuav tau ntsia qhov twg vim nws yog wireless tiag.

Txawm li ntawd los, lub sij hawm wireless muaj ntau dua ib tug txhais. Wireless koob yees duab tus IP uas txawv vim hais tias, thaum lawv kis lawm Wi-nkaus, lawv yuav tsis roj teeb powered — lawv tseem tau ib hwj huam cable qhib ua hauj lwm (tsawg tsis mus li ob peb teev). Muaj lub hwjchim qaum fundamentally pauv tus plahaum, txawv lub andquot; lick thiab stickandquot; ntawm cov tshuaj wireless tswb.

Muaj lwm yam txawv zoo li no. Txhua lub nruab wireless tswb siv ntau sab RF frequencies (400MHz - 900MHz) sib txuas lus rau peripheral li tshaj 2.4GHz nyob Wi-nkaus. Lub sab frequencies mus rau lub tsev ntaub ntawv zoo, mus los ntawm phab ntsa, ceilings, plag tsev, rooj tog zaum thiab chaw ua hauj lwm ntsuas. Qhov no yog vim li cas ib tias tub ceev xwm radios siv qhab zaus 700MHz - 900MHz; nws yeej muaj qhia nyob hauv tsev thaum lawv tsiv mus nyob hauv ib lub tsev los yog campus tseem.

Lub siab 2.4GHz zaus ntawm Wi-nkaus no tsis tsim los mus rau lub tsev ntaub ntawv tiam sis kis ntau nqi nyiaj ntawm cov ntaub ntawv. Tiag mas, Wi-nkaus yog tsim los npleem phab ntsa thiab lwm qhov chaw kom maximize kev pab them nqi. Qhov no yog vim li cas thiaj andquot; spotsandquot tuag; tshwm sim hauv lub tsev thiab lub chaw ua hauj lwm tes hauj cov muaj lwm hauv Wi-nkaus. Kuj yog qhov qhia fais fab noj.

Lub sab frequencies siv lub tswb qhia tau ntau yam zoo rau lub qub zog, tseem ceeb rau lub roj teeb powered ntaus ntawv uas yuav tsum tau khiav rau xyoo rau ob peb AA roj teeb. Txawm peb yuav tsis xav txog nws, peb pom cov teeb meem reflected nyob raws kiab khw. Peb tsis nrhiav Wi-nkaus qhov rooj muaj mob los yog PIRs nyob rau hauv cov khoom catalogs vim lawv xav tau ib lub hwj huam qaum thiab donand #39; t haum lub tswb wireless qauv.

Wireless tswb tshuab yog ua ib ncig lub roj teeb powered paradigm rau maximize nruab yooj yim. Muaj peev xwm mus rau phab ntsa, plag tsev, thiab lwm yam ntaub ntawv tsev mas tseem ceeb heev rau cov tswb installer vim nws pab tua andquot; spotsandquot tuag; thiab frustrations nrog rau ntau yam xwb.

Raws li pov thawj video sunburn mainstream, qhov txawv nrab roj teeb-powered thiab Wi-nkaus fais cords yuav tseem ceeb. Tshiab muaj wireless roj teeb powered yees duab koob yees duab raws li qhov tus wireless tswb qauv thaum lub hwj chim cords rau Wi-nkaus koob yees duab donand #39; t. Lub roj teeb powered sensor/lub koob yees duab no tseem fundamentally ib tug tswb ntaus ntawv. Thaum ob wireless khoom yuav muab pov thawj video, Wi-nkaus tseem muaj nyob ntawm tej thiab yog tsis yeej lawv Tswb los yog ntsia zoo li kev tswb ntaus ntawv.

Ntxiv dua thiab, peb pom no nyob raws kiab khw reflected li cov koob yees duab yoos yeej tsis wireless. Thaum yuav tsum tau ib hwj huam cable, khiav ib qho ntxiv miv-5 Ethernet cable ua rau kev txiav txim zoo thiab yog tus plahaum raug. Tus IP koob yees duab yeej xa tus nqi ntau, tab sis lawv donand #39; t ua raws li cov qauv lick-thiab-pas wireless plahaum uas ua lub nruab wireless tswb nrov heev.

Kab tias tsis txaus megapixel dluab, thaum uas cov 900MHz bandwidth yog sab txaus mus thawm yees duab VGA thiab ntau tshaj txaus video tseeb — tus tsav sib zog ntxiv koob yees duab ntawd rau wireless alarms ua tus xub place.
