Guide to Cameras 1

The traditional CCTV camera has a very industrial style and, therefore, many people would not find this suitable for fitting to their homes or shops.
This traditional style is actually a housing that is designed to keep the camera dry and within the recommended operating temperature. Thermostatic heating elements within the casing also reduce condensation and misting.
These types of top-end cameras are usually specified without a lens, this being chosen to give the required focal length and field of view. Motorised pan and zoom lenses allow an observer to follow or move in closer to the person or object in view.
We can supply these types of cameras to those of you who do not find the price prohibitive. Please contact us with your requirements.
Fortunately, for those of us with more down-to-earth budgets modern technologies now allow the production of cameras with excellent performance. There are two common types of CCTV cameras, CMOS and CCD (see glossary of terms). CMOS based cameras are generally cheaper but do not produce as clear or sharp images as CCD cameras. There is little point installing a CCTV camera if it is incapable of allowing you to easily identify who or what is being captured and recorded. CCD cameras provide pin-point clarity and should be specified wherever possible.
The KT&C, Everfocus and Concept camera range, in general use the Sony CCD chipset. Beware of competing products that do not state whose chipset is used.

Integrated cameras and lenses often referred to as "bullet cameras" are sealed to prevent ingress of moisture. The sealing is so good that they can be permanently immersed to some considerable depth in water if required.
Bullet cameras do not need a heater and their small size makes them highly suitable for fitting to domestic and commercial properties. It is not possible to make adjustment to these cameras because they are permanently sealed. Most of the bullet cameras in the 2seetv store are fitted with a 3.6mm lens which gives a 72 deg angle of view which is suitable for most domestic and small commercial properties.
