How an Expert of Analog Cameras Chooses IP Cameras
An expert of analog cameras knows that regardless of the output resolution, the true image quality is defined by a high quality sensor and a proper lens, the joint performance of which can be measured by TV lines. For NTSC and PAL standard devices 540 TVL is considered as a top quality.
The high quality camera should also support DC-iris lenses so that it could provide clear and stable picture even under frequently changing lighting conditions. It could contain a highly sensitive image sensor that provides clear video even in low light conditions and avoids smear, such as Sony EXview HAD CCD sensor.
If an IP camera meets the above mentioned requirements then it is a safe choice for an expert of analog cameras – get the proven video quality and all the additional benefits that IP-network has to offer.
