Help with Installation....

Recommended Posts

Hello everybody, well this is the second time im installing a dvr system and i have a couple questions.

 

what kind of dvr cards are the best? because i've put a 9 bit card but i didnt like it the image quality and also how is the quality of the 10-bit card.

 

what is the difference of the 1/3 and 1/4 cameras, i suppost that the 1/3 is better than the 1/4 but i just want to know why.

 

sorry to be putting this kind of post but one of my friends wanted to tell me this information!!

 

thanks

The 1/3 and 1/4 refer to the size of the imager. Well it goes back to the diameters of the tubes used in very old cameras. A general rule of thumb is the larger the imager the more sensitive it is. Two identical CCD's in 1/4" and 1/3" have the same number of pixels so the pixels are bigger and hence more sensitive on the larger CCD.
