Guide to CCTV – Cliqenect Online

There are a vast range of CCTV products and prices to choose from in the marketplace but little information to help discriminate between them. Here are some examples.

A camera described as good in low-level light will often not produce images at night unless there is additional lighting. There may be no explanation or qualification of the term low-level light.

Wireless cameras can be fitted in minutes as there are no cables to run back to your TV or monitor. However, the cameras still require a power source and while battery power is convenient, the energy consumption is great giving a working time of less than 24 hours (as low as 2 on some products tested).
Wireless connectivity is nevertheless very useful for some applications however.

At Cliqenect, we test various CCTV products, and use only equipment that meet your security surveillance requirements.

Cameras
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.analog-cameras
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. Motorized 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 Cliqenect here with your requirements.

orignallogoFortunately, 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. CMOS sensors were used for the lower quality cameras. However, with the introduction of High Definition CMOS sensors from Sony this is no longer the case.
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 and HD CMOS cameras provide pin-point clarity and are deployed by Cliqenect wherever possible.At the lower resolution the Sharp sensor is now extremely good and is ideal in capturing quick changing scenes.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 Cliqenect deploys 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. Please contact us if you require alternatives.
Another type of enclosure is the Anti-Vandal dome. modern-cameraAgain the cameras are sealed and often specified with IR LEDs for night-vision. These type of cameras are now the most popular for domestic and commercial installations.
