The make of my dvr is Avtech 791ZA . The cameras performance in the day time is good , so probably there is a problem with the IR part or LEDs . The question still stays , if i need to buy another one ; which one should i buy ( ofcourse at a moderate price ). Please reply . Thank you.

In non IR mode should the clarity and size be as seen by human eyes .

you mean to say there is no noise filtering mechanism . Can the lack of clarity be due to a poor quality sensor or something else ,like LED etc.

Hi everybody , Please suggest a good IR camera , with upto 25 mtr clear night vision and wide camera angle . The one i bought gives hazy image and captures lot of noise ( dust particles etc ) in low light and the outdoor picture quality is very low as compared to bare eyes. Thank you.

Thank you Soundy for the useful post .

Hi everybody , Can anyone please send the link for avtech dr040 dvr manual download . Does avtech dr040 have simultaneous recording and viewing ( live and recorded video ) options and BNC out. Thank you.

Thanks Christopher

No , i want to see the video ( recorded through dvr as well as live ) on the tv set . Is it possible with the dvr or using some additional attachment .

Hi everyone , please tell whether IR camera works in fog and smog . Thank you.

Hi everybody , please tell whether AVTECH DR040 can be used for simultaneous recording and playing on tv . If not please suggest some other model or cost effective solution ( converter etc. ) Thank you.
