Afã a ɛnyɛ den sɛ wobebu ani agu so wɔ IP mfoninitwa afiri sɔhwɛ mu ne ahosiesie. Ansa na wobɛfa mfoninitwa afiri foforɔ no, di kan si nneɛma mmiɛnsa so dua: 1 mfoninitwa afiri no PoE ahoɔden a ɛhia (voltage range, maximum power consumption); 2 ntwamutam a atwa yɛn ho ahyia (sɛ ebia switch port no boa PoE, VLAN nhyehyɛe, bandwidth anohyeto); 3 sɔhwɛ botae ahorow (a dwumadi ahorow hia nokwaredi — video, PTZ, alarm I/O, akyirikyiri kwan).
FangService no PK69 series network engineering adwinnade no kyerɛ mprempren link no PoE tumi tebea bere a boot ankasa-hwɛ, a voltage a ɛwɔ hɔ ne tumi a ɛsen biara a wobetumi de ama ka ho. Sɛ camera no rated power consumption bɛn link no maximum supply tumi a, ɛsɛ sɛ wɔhyɛ eyi nsow wɔ sɔhwɛ amanneɛbɔ no mu — ɛnkyerɛ ɔhaw ankasa, nanso ebetumi abɛyɛ bottleneck bere a upgrade anaa de nnwinnade aka ho daakye.
PoE tumi nokwaredi yɛ anammɔn a edi kan wɔ IP mfoninitwa afiri sɔhwɛ mu ne anammɔn a ɛyɛ mmerɛw sɛ wobehuruw. Nnipa pii susuw sɛ ‘sɛ switch no boa PoE a, mfoninitwa afiri no bɛyɛ adwuma yiye.’ Nokwarem no, PoE tumi yɛ nhyehyɛe mfiridwuma ho asɛm — switch no PoE chip, cable waya gauge ne tenten, RJ45 crimp su, ne camera no tumi management circuit — link biako biara a entumi nyɛ adwuma yiye betumi ama ahoɔden a ɛnnɔɔso aba.
Ɛsɛ sɛ PoE sɔhwɛ a ɛteɛ no kɔ so wɔ anammɔn abiɛsa mu: 1 susuw switch-end output voltage (normal range is typically 44-57V DC); 2 susuw camera-end input voltage (sɛ cable no ware dodo anaasɛ wire gauge no yɛ teateaa dodo a, voltage no so tew kɛse); 3 bu akontaa wɔ voltage margin (switch-end voltage a wɔayi camera-end voltage no yɛ pɛ cable voltage drop). Mpɛn pii no, ɛnsɛ sɛ ahoɔden a ɛkɔ fam no boro 5V — sɛ nhama a ɛyɛ mita 80 ma ahoɔden a ɛkɔ fam boro 5V a, ɛkyerɛ nhama no su anaa crimping haw. FangService's PK69 ne PK68 series nyinaa boa bere ankasa mu susuw PoE voltage ne current, boa engineers ma wɔyɛ ntɛm wie saa anammɔn abiɛsa yi.
Video su ho sɔhwɛ ne ade titiriw a ɛwɔ IP camera debugging mu. Mfonini no a wubehu no yɛ ade a edi kan ara kwa; sɛ́ wobehu sɛ ebia mfonini no ‘fata’ no hwehwɛ sɛ wɔyɛ nhwehwɛmu wɔ nhyehyɛe kwan so kɛse. Metrics titire no bi ne: resolution (1080P vs 4MP vs 8MP), frame rate (bere ankasa 25fps vs 15fps vs 10fps), bitrate (constant bitrate CBR vs variable bitrate VBR), kɔla a wɔsan yɛ (adwumayɛ wɔ kanea tebea ahorow mu), ne latency (bere fi mfoninitwa afiri mfoniniyɛ so kosi ɔyɛkyerɛ). FangService's PK68 series professional video tester boa overlay analysis nnwinnade — ebetumi ada kɔla histograms, grayscale sɔhwɛ nhyehyɛe, ne distortion detection adi wɔ live image no so. Saa nnwinnade yi boa mfiridwumayɛfo ma wowie video no su ho nhwehwɛmu titiriw a wonni kɔmputa. Wɔ tebea horow a ɛhwehwɛ sɛ wɔyɛ nhwehwɛmu a ɛkɔ akyiri (te sɛ dede a hann kakraa bi mu nhwehwɛmu, tumi a ɛtrɛw sɔhwɛ) ho no, wɔkamfo kyerɛ sɛ wɔmfa kɔmputa so dwumadi a ɛyɛ adwumaden nni dwuma wɔ biako mu.
Wɔ video a wɔde mena mfitiaseɛ akyi no, IP mfoninitwa mfiri taa de PTZ control, alarm input/output (Alarm I/O), ne akwan mmienu so ɔdio. Saa dwumadie yi taa yɛ mfitiaseɛ-verified nko ara wɔ instɔlehyɛn nanso ɛbɛtumi ada ɔhaw ahodoɔ adi berɛ a wɔde redi dwuma ankasa.
PTZ control huammɔdi a ɛtaa ba no bi ne: RS485 A/B line reversal (ɛma PTZ ntumi nkyinkyin anaasɛ ɛnkyinkyin wɔ akyi), baud rate a ɛnhyia (PTZ bua brɛoo anaasɛ ɛnnyɛ koraa), ne gyinabea ahorow a wɔahyɛ ato hɔ a ɛnnɔɔso (adwuma no hia boro mfoninitwa afiri mmoa so). Alarm I/O huammɔdi a ɛtaa ba no bi ne: voltage matching nsɛm wɔ alarm input terminals (active vs passive alarm devices) ne software nhyehyeɛ mfomsoɔ wɔ alarm triggering mu. FangService's PK69 ne PK68 series boa RS485 PTZ control sɔhwɛ, a ɛtumi de control ahyɛdeɛ mena na ɛhwɛ sɛ PTZ mmuaeɛ yɛ nokware. Alarm I/O sɔhwɛ hwehwɛ sɛ ɛne mfoninitwa mfiri pɔtee bi ne alarm mfiri hyia. Ansa na wɔde adwuma no bɛkɔ no, wɔkamfo kyerɛ sɛ yɛ ade biara mu nhwehwɛmu a edi mũ wɔ nneɛma a ɛkɔ anim nyinaa ho — ntwɛn kosi sɛ adetɔfo no bɛbɔ amanneɛ sɛ ‘PTZ no renyɛ ho biribi’ na woahu ɔhaw no.
