What is the BEST CCTV Camera available?

I am looking for a CCTV camera, which would be able to capture video of proper HD quality, and which should be able to produce a very good quality of video during both day and night (so that it would be able to zoom in on faces at a distance of 10-20 metres). What is the best camera available at present, and how much does it cost?

Hello

Note: The DVR (digital video recorder) is just as important as the camera.

Yes High definitions mega pixel cameras do offer some advantages but are extremely limited in there applications. and represent less then 1% of the total market yet are often touted as the main advantage IP cameras over analog cameras. Mega pixels cameras are limited because of there poor price to performance ratio, large file size, low signal to noise ratio, motion blur, and most are based on CMOS which means they inferior ability to cope with ambient lighting such as back light, bright, deep shadows contrasts, low light and IR this is also known as the real word so are often only used in non critical indoor applications. (why mega pixel cameras are less then 1% of the market)

CCTV HD cameras are based on CMOS what you want is CCD.

CCD image sensors contain hundreds
of thousands picture elements, called pixels. Each pixel contains a light sensitive element and a capacitor.

This means CMOS has some significant disadvantages compared to CCD, this means CMOS
have inferior ability to cope with ambient lighting such as back light, bright, deep shadows contrasts, low light and IR this is also known as the real word.

If you want a good image go CCD if you want a big image go IP CMOS.

In short unless you have perfect lighting a good CCD camera will outperform an equivalent CMOS camera.

IP cameras have up to a 5X larger file size then analog cameras. (at same resolution) I have seen MP cameras that on 2MP resolution are over 300X (%3000) then a CIF image. This is an extreme case but generally speaking IP cameras have a much larger file size.

If you compare a good D1 resolution image and compare it with a 2MP you will very little deliverance any many times I have had people who choose the D1 using out 550TVL camera due to its better color reproduction and its ability to handle changing ambient lighting conditions.

What I suggest. PTZ Camera
A Pan-Tilt-Zoom camera (PTZ Camera) is a closed-circuit television camera with remote directional and zoom control. PTZ cameras allow users to take the driver's seat and aim cameras exactly where they want. The use of PTZ cameras is generally a very advantageous solution for the surveillance of a site since it makes it possible to cover a wide surface with only one camera. Ascendent's PTZ line-up ranges from precise weather-proof domes to high performance, explosion-proof housings. These cameras give you full capability to maneuver your way to areas of concern with 360° panning, long-range optical zoom, and 180° or more tilt range.

If you want night vision you will need IR: http://www.ascendentgroup.com/downloads/cameraspecs/FLEX-23X-LIR.pdf

Unparalleled Active IR Imaging
Unlike traditional IR night vision cameras that use standard CCD lenses and LEDs that operate autonomously, Ascendent's Active IR cameras have integrated AMC (Automatic Processor Control) and EPC (Electronic Photocell Control), MICF and a host of other technologies, to ensure the Optics, image sensor, lens, MICF and super bright IR LEDs work in tandem to eliminate hot-spots, washout, and under exposure usually associated with IR cameras. For flawless active IR performance up to 200m (650ft) Ascendent's IRs are optimally spaced and use different sized and angled LEDs to provide evenly distributed IR to offer both long range and wide angle illumination. Ascendent's IR cameras are designed to offer absolute performance and use the highest quality components and unique manufacturing processes to increase performance and reliability such as dual PC board design and hand welding of all the IR LEDs (Vista and Apex Series). All these components are integrated into rugged IP 66-68 Nema 4X enclosures constructed of extruded aluminum and thick, high- impact, optically pure polycarbonate to withstand the most brutal assaults and extreme climates for 24/7 surveillance in mission critical applications.

I would recommend using Ascendent CCTV Equipment http://www.ascendentgroup.com/

If you like send me an email ill show you a white paper about how to evaluate image quality.

Hope this helps
