Kamery jsou postaven\u00e9 na digitaliza\u010dn\u00edm chipu SONY a procesoru HiSilicon. Chip poskytuje kvalitn\u00ed obraz v rozli\u0161en\u00ed 1920×1080 (full HD) a sn\u00edmkovac\u00ed frekvenc\u00ed a\u017e 30 fps (dle sv\u011bteln\u00fdch podm\u00ednek). Podle prostorov\u00fdch pot\u0159eb jsme schopni dodat kamery s r\u016fznou ohniskovou vzd\u00e1lenost\u00ed \u010do\u010dky a pokr\u00fdt tak \u0161irokou \u0161k\u00e1lu pohled\u016f.<\/p>\n
Zaj\u00edmavou funkc\u00ed je WDR (wide dynamic range). Tato funkce p\u0159i zapnut\u00ed zp\u016fsob\u00ed vyrovn\u00e1n\u00ed rozd\u00edl\u016f mezi sv\u011btl\u00fdmi a tmav\u00fdmi m\u00edsty v obrazu. Zabr\u00e1n\u00ed tak tomu, aby \u010d\u00e1ste\u010dn\u00e9 osv\u011btlen\u00ed nap\u0159. sluncem ztmavilo z\u00e1znam zast\u00edn\u011bn\u00fdch m\u00edst. Intenzitu WDR je ov\u0161em t\u0159eba nastavovat s rozvahou – do obrazu vnese trochu digit\u00e1ln\u00edho \u0161umu.<\/p>\n
Ka\u017ed\u00e1 kamera je vybavena jak ethernetov\u00fdm portem pro kabelov\u00e9 p\u0159ipojen\u00ed UTP kabelem, tak bezdr\u00e1tov\u00fdm vys\u00edla\u010dem WiFi. Je tedy mo\u017en\u00e9 kamery nainstalovat i bez zbyte\u010dn\u00fdch elektroinstala\u010dn\u00edch prac\u00ed nap\u0159. napojen\u00edm na existuj\u00edc\u00ed elektrick\u00e9 okruhy sv\u011btel a sign\u00e1l pos\u00edlat bezdr\u00e1tov\u011b. V p\u0159\u00edpad\u011b dr\u00e1tov\u00e9ho p\u0159ipojen\u00ed je samoz\u0159ejmost\u00ed pou\u017eit\u00ed technologie PoE pro minimalizaci kabel\u00e1\u017ee.<\/p>\n
Kamery maj\u00ed odoln\u00e9 hlin\u00edkov\u00e9 \u0161asi a odpov\u00eddaj\u00ed standardu IP67, tedy odolnost v\u016f\u010di prachu i tekouc\u00ed vod\u011b. Je tedy mo\u017en\u00e9 je montovat jak dovnit\u0159, tak ven.<\/p>\n
Sada siln\u00fdch infra\u010derven\u00fdch LED diod s vlastn\u00edmi \u010do\u010dkami zaji\u0161\u0165uje rovnom\u011brn\u00e9 a dalek\u00e9 pokryt\u00ed infra\u010derven\u00fdm p\u0159\u00edsvitem i pro p\u0159\u00edpad absolutn\u00ed tmy. Tato konstrukce je\u0161t\u011b vylep\u0161uje mo\u017enosti ji\u017e tak velmi citliv\u00e9ho chipu.<\/p>\n
P\u0159es v\u0161echny tyto skv\u011bl\u00e9 vlastnosti jsou kamery velmi \u00fasporn\u00e9 a maj\u00ed maxim\u00e1ln\u00ed odb\u011br do 12 W.<\/p>\n\n\n
