Chipatala cha SIP Paging JWDT-PA3

Kufotokozera Kwachidule:

Kapangidwe ka JWDT-PA3 kamagwirizana ndi makina onse amkati, makamaka poulutsira mawu pagulu. Ndi ma audio a HD ndi ma interfaces okhala ndi magwiridwe antchito ambiri, JWDT-PA3 ingagwiritsidwe ntchito poulutsira mawu a MP3 nthawi yeniyeni komanso nthawi yokonza, komanso intercom yokhudza kamodzi mukalumikiza ku zida zakunja. JWDT-PA3 ndiye chisankho chanu chabwino kwambiri chodzipangira njira yolumikizirana yolumikizirana pasukulu, malo ogulitsira, siteshoni ya sitima, nyumba, ndi zina zotero.

JWDT-PA3 ndi yaying'ono komanso yokongola, yomwe ndi yoyenera malo ochepa m'mapulogalamu ambiri. Ndi ma audio decoding a G.722 ndi opus, JWDT-PA3 imapatsa ogwiritsa ntchito mwayi womveka bwino wa telecom. Ili ndi ma interfaces olemera ndipo imatha kupangidwa kukhala zida zowulutsira, ma amplifier ndi ma intercom kuti ikwaniritse zofunikira zosiyanasiyana. Kudzera mu USB interface Max to 32G kapena TF card interface, JWDT-PA3 ingagwiritsidwe ntchito powulutsa MP3 pa intaneti komanso pa intaneti. Ogwiritsa ntchito amatha kuwona chithunzi cha HD cha kamera pafoni ya IP kudzera pa SIP Paging Gateway iyi, kuti aziwunika momwe zinthu zilili nthawi yeniyeni.

Zinthu Zofunika Kwambiri

1. Chokongola kwambiri, chitha kuyikidwa mu zida zina kuti chiyikidwe mkati

2. Mphamvu ya amplifier ya mono channel ya 10W ~ 30W, malinga ndi mphamvu ya input voltage yomwe imayikidwa.

3. Mzere wa mawu mu doko, mawonekedwe a audio a 3.5mm wamba, pulagi ndi kusewera.

4. Cholumikizira cha mawu, cholumikizira chakunja chomwe chimatha kukulitsidwa.

5. Thandizani doko la USB2.0 ndi malo osungira deta kapena mawu osagwiritsidwa ntchito pa intaneti.

6. Doko lolumikizira la netiweki la 10/100 Mbps losinthika la PoE.

Kugwiritsa ntchito

JWDT-PA3 ndi chipangizo cha SIP Public Announcement system chomwe chimagwiritsidwa ntchito m'makampani. Chimatumiza mauthenga kudzera mu ma protocol a IP/RTP/RTSP. Chili ndi ntchito zosiyanasiyana komanso ma interfaces, monga Intercom, kuwulutsa ndi kujambula, kuti chigwirizane ndi malo osiyanasiyana ogwiritsira ntchito. Ogwiritsa ntchito amatha kupanga mosavuta chipangizochi.
