  • minsan nag down din server nila kaya may time na hindi ka makapag remote viewing.
  • ano pinagkaiba ng mga camera na HD(720P or 1080P) dun sa camera na 700TVL, 1000TVL or 1200TVL? nagtanong kasi ako sa isang seller hindi daw pede yung mga HD cam sa ordinary na DVR..

    This 4 camera split image demonstrates the top two analog cameras connected over coax cable...
    700 TVL (approx. 500,000 pixels) vs. 1000 TVL (approx. 1,000,000 pixels)
    as compared to the bottom two IP cameras connected over Cat5 wire...
    1.3 Megapixel (approx. 1,300,000 pixels) vs. 3.0 Megapixel (approx. 3,000,000 pixels)

    Note the images created by the better cameras are increasingly clearer as they are produced with more pixels. If you want to zoom in, Save this image to your PC and open with a viewer. Pick an object, for instance the yellow cord plugged into the pole. Now, zoom in on each of the 4 images. You will readily see that as you zoom into the higher megapixel images, the clarity is maintained better since there are so many more pixels.




    HD, More pixel,more details,better area coverage po.

    Madami na po HD technology na pwede pagpilian, may IP,SDI, CVI, TVI at AHD.

    If budgets permits, always go for HD na.

    700TVL,1000TVL or 1200TVL resolutions of analog cameras.
    Use by common DVR mostly with QCIF,CIF,D1,960H recording.
    While, HD(720P or 1080P) are high definition resolution in megapixels.
    Resolution use by: IP,SDI,CVI,TVI,AHD cameras.
    It has different type of DVR or NVR to record.
    HD and megapixels mas advantage lalo na sa zooming.

    Below is a sample chart:

  • question mga masters.

    merong scrolling dark line yong isang HDCVI camera ko. yong iba naman wala. ito yong screen shots. kitang kita lalu na sa night or IR mode.

    ground loop ba ito? ready made siamese cables lang gamit ko. mawala kaya ito kung palitan ko ng RG59? sinubukan ko ng maglagay ng ground loop isolator pero walang improvement.

    try ko munang palitan ng RG59 with power. pag andon parin palit na siguro ako ng camera. Thanks.

    ito yong meron line:

  • low power yan sir..
  • ^ah OK. try ko measure voltage niya mamaya. thanks.
  • Kung hindi naman dati ganyan at wala kang iniba sa setup,
    try mo check at tanggal connect mga power supply port ;]
  • ^dati na ganyan ng kinabit ko eh. kaya suspect ko yong camera talaga.

    kahit pagpalitin ko lugar at cables ng mga camera ganyan parin yang isang yan.

    nag check ako ng voltage ok naman. nasa 11.68v.
  • sa camera yan.
  • ^thanks. sana palitan ng seller.
  • Kung under warranty pa bakit hindi ;]
  • Magkano ba magagastos sa CCTV setup na:

    - 3 cameras
    - latest 30 days lang ang itatabi na video footage for viewing purposes
    - video resolution is 480p (ok na ba ang 480p ?)

    Thanks

    naka power splitter ka ba boss? ganun dati sa akin nagpalit lang ako ng mas mataas na ampere.

  • thanks sa mga suggestions

    pero yong power supply ko ay silverstone sfx 450 watts na naka splitter kaya hindi kapos sa ampherage.

    na try ko na rin ilagay yong adaptor ng dvr mismo na 5 ampheres sa problematic na camera pero ganon parin :(
  • Magkano ba magagastos sa CCTV setup na:

    - 3 cameras = P12K+ IP camera
    - latest 30 days lang ang itatabi na video footage for viewing purposes = 1TB HDD P3K
    - video resolution is 480p (ok na ba ang 480p ?) = dahil gusto mo may p(resolution)
    walang (p) sa standard it stands for HD kaya recorder mo NVR = P4K+
    - marami pa iba + cable, accessories, installation, commission ehe, etc.

    Thanks
