Cctv basic questions Cameras (Common Questions)


There are many basic questions concerning the security systems which people mostly ask to know more about them. Cctv basic questions will try to answer them.

Before one buys or manage a security camera, he/she will always inquire on various CCTV basic questions which may include:

What Are The Difference Of Hardware And Software Compression

Common Questions For CCTV Cameras • Most people will want to know how is compression differentiated.

• In Hardware compression, capturing and compression of the video signal are all performed using a DSP chipset which is integrated onto the DVR board.

The CPU of the computer isn’t needed in doing the work since it has low RAM and CPU cost resources.

The hardware compression allows computer’s CPU task to be audio/video streaming into the network, answering various network requests, having recorded data saved on the local hard disk.

• The Software Compression: it enables the DVD board to capture video signal only and not to compress it since the RAM and computer CPU are the ones set for compressing.

They have high RAM and CPU cost resources. Here, the RAM and CPU of a computer tend to be overloaded which makes it easy to crush.

How To Select The Camera That Fits Your Application

• It always has been a difficult decision to make. You need to consider various installation aspects so you can obtain the best performance which suits your needs.

You can consider selecting high-resolution cameras if the scene details being needed are great. When you select a very sensitive camera, then most poorly lit areas will have their production improved.

The camera sensitivity is denoted using the minimum light amount which will enable the camera in producing usable pictures.

• The conventional cameras produce pale backdrops mostly when you shoot the object against the brighter backgrounds.

The Black Light Compression hence counters very strong light sources, and they finally retain quality pictures.

The concentrated light sources that are directed on the camera direction like the car headlamps may be inverted using the optional eclipse function.

Their effect will then be taking the details into the area hence making clear objects which would have been shadowed.

How Does One Set Up Lens And Cameras In The Condition That Needs Low Light

• When you set the color camera back focus in low lighting conditions, you need to place the Neutral density one filter onto the lens front.

When you set a mono-camera back focus in low lighting conditions, then place the neutral density three filters at the lens front.

When you set back focus of the mono-camera that has a low lighting condition for an I/R lighting, ensure the Infra-Red Pass is placed at the lens front.

Why Re Sharp Images Not Being Obtained After Installing Lens And New Cameras

• When you want to resolve a question like that, is very simple since you only need to make sure that the lens and your new cameras have both the same amounts.

It means the same ’ lens amount onto the ’ camera and S’ lens amount onto the S’ mount camera.

What Does OSD Cameras Means

Why The Day Brings Clear Picture Which Is Not The Case At Night Time

• The reason is because of the field changing depth since light conditions change is overcome easily when the set procedures are followed well.

When The Manual Iris Lens Can Be Used

• The basic rule is using the MI lens, especially when carrying out internal applications. The reason is that one relies on the camera’s electronic circuitry which compensates towards the lighting changes at the scene which isn’t able in compensating the similar degrees compared to the ones from auto iris lens.

How Can One Back Focus The camera That Has Fixed Length Focal Lens

If you need to back focus, then you must accomplish the process using the following simple ways.
• Set the physical lens focus towards the infinity which should be clockwise basing at the front.
• Aim your camera towards the object you want to view.
• Release the back focus camera mechanism.
• Adjust the camera’s back focus mechanism so you can obtain the best picture quality.
• Then secure the back focus mechanism of your camera.

The above are just some few among many CCTV basic questions that people always want to know before they purchase a CCTV of their own.
