There are lots of 700TVL cameras going around cheaper than an E700, but you never know what you're going to get and I think most forum members who have tried the cheap cameras have been disappointed and finished up buying an E700 anyway.
As they say - "buy once cry once"

Cheers

I don't think there is such a thing as a normal 700 tvl camera as the sensors and image processing software make a huge difference.

I'm far from being an expert but as far as I understand it there are 3 main aspects to a camera; resolution, sensitivity and image processing. The TVL value stands for television lines, ie the resolution of the image so very loosely the higher the number the clearer the picture. The sensitivity is largely dependent on the type of sensor. Essentially there are CMOS and CCD type sensors but as far as I know the CCD ones are better for our need, and these CCD cameras come with a variety of different level sensors so at the bottom of the Sony range is Super HAD, then a Super HAD II, then Exview HAD and finally and most sensitively is the Exview HAD II. The images processing chip, such as the Effio e chip, processes and optimises the image.

The e700 has the Sony Exview HAD II CCD in 700 TVL and some top processing to make it the best current camera but cheaper cameras with the same sensor will work but probably not quite as well.
