1. Warranty
When you buy CCTV camera asking about warranty is amust , Branded CCTV components are highly reliable and are expected to deliver on their promises. However, even if there are any faulty products, these are most likely to fail within the first 90 days of use which is within the manufacturer’s warranty period. Therefore, purchasing extended warranty coverage may not be required.
2. Type and Quality chip in camera
There are two type imaging Chip in Camera : CCTV security cameras produce images using CMOS or CCD (Charge Couple Device) chips. Tiny and/or very low price CCTV cameras usually use CMOS technology, produce poor quality video and have very poor light sensitivity. Decent quality and better CCTV cameras use CCD technology. The size of the CCD chip is normally 1/4", 1/3" or 1/2". As a rule of thumb, the larger the size, the higher the quality of the image produced and the higher the price. However, higher density 1/4" and 1/3" CCD chips can now produce as good an image as many older 1/3" or 1/2" chips.
