    Thank you Cooperman for replying each question.

    Regarding quest 2 i was looking for diffrence between picture qaulity of a cctv monitor and TV.

    If a good performing camera of 480 resolution, 0.1 lux minimum illumination and S/n ratio of more then 48 db at AGC off placed indoor in excelent light conditions,how it will perform on a 21 inch sony vega as compared to cctv monitor of 600 tvl and if the same camera installed outdoors with poor light conditions at night ,which of the two will give better results .

    I have a Stand alone DVR Naming X-VISION.

     

    it has real time display and record speed of 50 fps. Did any body know its actual manufacturer? i only know that this DVR is made in korea.

     

    I am facing a problem in this unit, when i connect the lan cable it gives a flash of light on lan port and doesnt make connection to the network. i have also checked the cable and its fine.

     

    but when i connect the second unit it works perfectly on to the same cable.

    kindly helpme.

    Hi,

    I have a c-mount camera HR , and i have lences of F1.2 or F2.0 4mm standard from different manufacturers , so which lense either F1.2 4mm , or F2.0 4mm will give the best image results and what will be the diffrence.

    And one more thing i have experiance that a standard fixed lense works more better in day and night as compared to auto iris lenses (VD,DD).Why is that so?
