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.

Thats a locally assembled CCD IR camera .

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 .
