What is an OSD and Why is it Important?

Our new 700TV Line Cameras come with On Screen Display Controls.

OSD stands for On Screen Display, and it is available in all of our industry leading 700 TV line cameras. The benefits of an OSD are  that it provides a simple, efficient, and easily understandable way of changing the various settings of your camera.

The OSD of the device is easily accessible via a simple control attached to the power and video cord. With the user friendly OSD programmed into our 700TVL cameras, you can change the settings of your device in order to achieve the absolute best quality image and functionality for your unique surveillance setting.

Below are the various programmable features and settings provided by the OSD of our 700TV line cameras:

LENS: manual / auto

SHUTTER/AGC: manual / auto

WHITE BAL: atw / push / user1 / user2 / anti cr / manual / push lock

More on Shutter Settings?

This OSD allows users to adjust the settings of the camera shutter. For instance, setting the cameras electronic shutter to Automatic, allows the shutter speed to change with response to the amount of perceived light to keep the signal output at the best possible level.

This allows an iris to adapt automatically to different lighting conditions. When the shutter speed increases, the light passing through the lens is decreased and the cameras sensitivity is reduced. When the shutter speed is decreased, a larger amount of light enters the iris.

For fast moving objects the shutter speed can also be increased to provide a freeze effect in order to provide higher resolution images.

More on White Balance?

With this OSD, White Balance can be set to a number of settings. For instance, the Automatic White Balance setting allows the camera to adjust the tone according to the color temperature of the light source illuminating the subject.

It allows the operator to see objects as they appear during daylight. However, manually adjusting, or pushing the white balance feature is also available with this OSD, along with creating different unique savable user settings.

More on Backlight Settings?

Generally speaking, this OSD allows for adjusting the impact of backlight in various lighting settings. When Automatic Backlight Compensation or BLC is activated, the camera can sense the whole area of the frame and measure the average light level.

The working point will be based on general testing of the whole environment. If there is a very bright background with a very dim front image, back light compensation is activated so that the camera can apply light to the dark zone. With this feature a normally dark and unspecific image can be easily transformed into a clear and easily interpreted one.

What is a Privacy Mask?

Privacy masking or zoning is a great yet often overlooked and misunderstood feature. This OSD allows privacy masking settings to be adjusted. With a privacy mask, protection of personal privacy is possible by concealing parts of the camera’s image from view with a masked area i.e., transparent or pixelated effect.

This OSD allows for an ON/OFF setting to be applied to up to 4 separate privacy masks.

Day/Night Feature

This OSD allows for programmability of the Day/Night features included in these cameras. The settings can be set to Auto, Black and White, or Colour, to account for various lighting situations in order to provide optimal image quality at different times of day.

NOTE: adjusting the D/N feature at different times of day, for instance, to Black and White after dark; can often account for better visibility as seen below.

What is NR?

NR stands for Noise Reduction. Noise reduction is a powerful method for reducing image noise in  order to produce extremely clear images even in very dim lighting conditions. This OSD allows for considerable adjustment to NR settings.
