• Tell Me How Can I Eliminate Ground Loop Faults?
This can be achieved in a number of ways, the easiest of which is the installation of a Ground Loop Isolation Transformer. This is best installed at the monitor or recording end of the system.
• Tell Me What Is The Difference Between Auto Iris And Direct Drive Lenses?
An Auto Iris lens is one that automatically adjusts its iris for changes in the scene lighting levels. The motor that opens and closes the iris is driven by an Amplifier that processes a small electronic signal changing with the light level.
• Tell Me Does The 'f' Stop Matter When Choosing A Lens?
Yes, lenses are usually specified as having a minimum and maximum 'f' stop rating; the 'f' stop is a measure of how efficiently the lens allows light from the scene, to pass through the lens and onto the camera CCD sensor. The maximum aperture (when the lens is fully open), is the minimum 'f' stop number and the minimum aperture, (just before the lens completely closes) is the maximum 'f' stop number.
• What Is Digital Cctv?
Currently the majority of CCTV systems use Digital technology. Digital CCTV Surveillance uses current PC technology to digitize the CCTV camera images and compress them into a PC friendly format. These digital images can then be stored on a PC's Hard Disk Drive. As the digital cctv images are stored on computers Hard Drives it is possible to save digital cctv footages and access them speedily and easily. Digital CCTV also has the advantage over Analogue CCTV systems that the image is of a far higher resolution.
• Tell Me What Is The Difference Between Simplex And Duplex Multiplexers?
Video multiplexers are designed to allow recording of several cameras onto one recorder.
Simplex
A simplex machine is best suited to applications where recording only is the priority. Simplex machines cannot display multi screen images (i.e. quad, 9 way and 16 way split) while in the record mode.
Duplex
If an operator is monitoring the system (i.e. security guard) then a duplex machine is more suitable. A duplex machine can provide screen splits and user selectable images without affecting what is recorded onto the recorder. Should you use two recorders, it becomes possible to record and playback simultaneously.
• Explain Me What Qualities Do You Need To Be A Camera Operator?

There is a lot of walking, sometimes running, and a lot of lifting and carrying to be done so you must be relatively fit.
• What Is Analogue Cctv?
In the past, all CCTV Cameras were attached to a Multiplexor (A device that will split multiple camera pictures onto an individual CCTV Monitor). The Multiplexor then sends the analogue camera images to a Time Lapse Video Player. These are special CCTV recording devices that can record up to 960 hours of footage on a three hour Video Cassette. This method is still used today for simple CCTV installations but the quality of recording is usually very low (1 Frame Per 12.8 Seconds).
• Tell Me What Is A Ground Loop?
An AC current that can be produced in a cable. This is usually caused by parts of the system being fed from different electrical sources resulting in different earth potentials at each end. The result is interference on the signal, usually in the form of dark bands across the monitor and on occasion tearing in the top third of the image.
• Explain Me What Does The Work Involve?
I operate a camera on location or in the studio. I could film anything from a close-up of someone's face during an interview to a wide shot of the pitch and players during a football match. I use different techniques to ensure the shots are good quality, clear and visually interesting. The director or producer has an idea of how the finished film should look, and it's my job to make sure the shots I capture are as close to their vision as possible.

• Explain Me How Do I Set Up A Camera And Lens For Use In Low Light Conditions And Or With Infra Red Lighting?
When setting the back focus of a Color camera for low light conditions you should place an ND1 (Neutral Density) filter in front of the lens. When setting the back focus of a Mono camera for low light conditions you should place an ND3 (Neutral Density) filter in front of the lens. When setting the back focus of a Mono camera fitted with I/R lighting for low light conditions you should place an IRP (Infra- Red Pass) filter in front of the lens.

• Do You Know What Would I Do As A Tv Camera Operator?
As a TV camera operator, you record the images seen on television--from news broadcasts, TV series and sporting events to documentaries and commercials. You work with directors and technicians to find the most effective way to frame these images using elements such as lighting, position, lenses and camera movements. You must also be capable of moving their cameras smoothly and steadily. While many TV camera operators are only responsible for shooting video footage, some also edit their own work.
Some TV camera operators are studio operators, which means they work in a television studio and record images with the camera that is in a fixed position. However, in some studios, cameras are mounted on a track so they can be moved while filming. This is very different from news camera operators, who are on the move tracking news events. In this position, you must be prepared for both indoor and outdoor photography and even to edit your own work on the spot so it can be transmitted as live coverage. Since you carry your cameras on your shoulders, the ability to hold the camera steady is especially important.

• Tell Me What Is Video Termination?
This is the end of line resistance of any CCTV system and this should be set to 75 ohm. Should you encounter any double image or ghosting this is more often than not caused by two pieces of equipment in series both having the 75-ohm switch set on. Only the last piece of equipment should be set at 75-ohm.
• Do You Know When Can I Use A Manual Iris Lens?

• Tell Me What's The Difference Between Hardware Compression And Software Compression?
Hardware Compression: Both Capturing Video Signal and Compressing Video Signal are done by DSP chipset integrated on DVR Board. It doesn't need the computer's CPU to do this work. It's low cost of CPU and RAM resources. In this system the computer CPU's task focus on answering network request, streaming the video/audio to network and saving recorded data to local hard disk.
Software Compression: The DVR Board only capture video signal but doesn't compress it, it is the computer CPU and RAM to do this compression work. It's high cost of CPU and RAM resources. In this system the computer CPU and RAM are often overloaded. It is easier to crash than hardware compression system.
