Cctv Lens (Sony or Sharp)???

[Densio]

---

Guys I need your help on this.

I'm planning to buy a cctv system for my office pero naglibog ko between a Sony 1/3" lens and Sharp 1/4" lens. Ingon sa dealer pareha radaw ang quality pero I'm quite skeptical kung pareha ba gyud because of the price difference of about P600.00 per cam, with Sony na mas mahal.

Unsa man ang advantages sa Sony against sa Sharp in terms of video quality and durability of the unit.

Any technical explanation is most welcomed. I know the bigger the sensor (1/3" against 1/4") much better but a difference this small, I think, will not be noticeable but that's just what I think (I might be very wrong).

Please help guys. Thanks.

SONY vs. Sharp CCD- In surveillance equipments, these two branded CCD sensors are the most commonly used in the market. SONY branded CCD had been shown to provide sharper image resolution, better performance in low light conditions. SONY branded sensors is also more expensive.

3.6mm lens vs. 6mm lens- Common camera (cheaper) uses 6mm lens. A 3.6mm lens provides a much wider view for better coverage of surveillance area.

1/3" vs. 1/4" CCD sensors- 1/3" CCD sensors are able to reproduce a wider and larger area coverage due to the larger sensor. It is also mored expensive.
