What is CCTV ?

What many people don’t know, however, is that there are a variety of different types of CCTV camera which suit different situations or premises, and that selecting the proper camera for the right application really is vital.

It is common to have recorded evidence of employees misbehavior to be used in lawsuits. Sometimes the footage can also benefit the employee, it all depends on the situation recorded by the security cameras.

If you’ve been asking yourself, ‘what type of cctv camera should I buy?’ then you have come to the right place, because the experts here at Caught on Camera will be covering things to consider and the best types of CCTV cameras for the home. But first, there are 3 factors to consider:

This will ensure that you receive a quality image. Choosing the right lens will allow your camera to focus and will bring enough light to the sensor on the camera, helping you to read registration plates and recognise faces etc.

The first CCTV system was installed by Siemens in 1942 in Germany to monitor rockets launching during the war.

we run through these types of camera and what makes them unique and more suitable for some venues over others.

The first commercial version of the CCTV system appeared in 1949 in the USA.

cameras can pick up coloured images in very low-light conditions.

At first, it was not possible to record the images, but only to monitor live what was happening close to the cameras, years later, in the 1970s, analog tape recorders began to become popular and could be used in systems.

Having more detail will, of course, help in all situations, because it means that you will be able to see exactly what’s happening and get a clear record on film. A zoom lense can provide customers with more information because optical zoom can adjust the light as it reaches the sensor, enabling flexibility and enhanced pictures.

Dark fighter technology can be used in the day and night and offer optimal performance thanks to its wide range of capabilities

The concept of traditional analog CCTV systems is quite simple, a camera must be connected directly to a monitor through coaxial cables that can carry the analog signal.

Box cameras present an obvious sign for anyone who passes by that they are being recorded on CCTV and this can be a great deterrent of theft and crime. Whereas dome cameras are smaller and more discreet. These compact cameras are ideal for monitoring a larger area such as your front or back garden and can follow movement with ease.

The first analog CCTV cameras was a very low-resolution model. It was impossible to observe the details of objects and people with such a camera.

When thinking where you would like to place your cameras, you might want to think about how they will be mounted and housed, in order to ensure that they’re in the best location and well protected. For example, if your camera is to be placed outside, you will want it to be robust and weather proofed. If it’s to be placed indoors you will want to ensure it will not be affected by grease or steam from a kitchen.

Resolution on analog CCTV systems is measured in TV lines, which represents the number of lines generated and displayed on a monitor. This type of system will cease to exist in the next few years.

They are equipped with ½” CMOS progressive scan sensors which allows the device to pick up high-quality images and doesn’t require an extra light source – which makes the perfect night time security surveillance camera.

Test different camera models to see what works best with the lightning in your area, because no matter whether they’re inside or outside, the lighting will differ throughout the day. You will want to check any reflections and backlighting during the day and night.

The dome camera is one most commonly used for indoor and outdoor security and surveillance

The CCTV full form is closed-circuit television. It is a system used to transmit video signals from CCTV cameras to monitors or recorders. It is called “closed-circuit” because the signals are not broadcast publicly, but are accessed by certain authorized users.

Depending on how expansive the area is that you want to cover, the resolution of the CCTV camera you choose will need to reflect the landscape in order to provide a clear, useful image. However, if situated in a small room, the camera need not be of a high resolution.

Accordingly, the full form of CCTV cameras is closed-circuit television cameras. Due to the extensive application of CCTV systems in security industry, CCTV cameras mainly refer to security cameras for home and business surveillance.

Audio isn’t required, however, if you do wish to opt for audio there are systems where you can speak to a person who has broken into the property. Audio can be used to deter criminals by automatically playing something when they get a certain point inside, an ideal way to make them think that there are people inside the building.

The shape of the camera makes it difficult for onlookers to tell which way the camera is facing, which is a strong piece of design, deterring criminals by creating an air of uncertainty.

The earliest documented application of the CCTV camera system dates back to 1942 – longer than you may think. Walter Bruch, a noted German engineer, designed and installed the system that used CCTV cameras to observe the launch of V2 rockets on monitors.
