When you have CCTV cameras installed around your property, it makes sense to try and get the best quality images and video possible. Just settling for average picture quality means you will most likely not be able to positively identify faces captured by your CCTV cameras, enough for the footage to be used in as evidence in litigation.
Having your CCTV cameras adjusted to the correct settings will make a huge difference to picture quality and clarity. It’s not a good idea to rely on factory default settings as these are basic settings and meant to be changed to meet the individual circumstances of your CCTV cameras placement.
- Adjust your CCTV cameras to meet the requirements of the setting or areas you’re using them, such as a long corridor, in the home, family room, your foyer, entrances or exits, cashiers areas, waiting rooms or external areas such as doorways, car parks, landscape scenes
- It’s important to take into account the changing light conditions during the daytime and nighttime. These differences will have a dramatic effect on the picture quality, such things as
- Reflected light
- Back lighting
- Sunlight and the movement of the sun during the day
- Flood lighting and lights designed to illuminate the area being monitored
These all need to be taken into account when accessing your CCTV camera’s settings, position and the footage you will receive from them.
Getting the best from your CCTV cameras is a matter of using the best quality lenses, CCTV cameras and data storage systems available. The use of cheap and unfocused lenses results in reduced levels of clarity.

The images you see are made up of a large number of coloured dots called pixels.
The number of pixels in each image basically determines the detail of that image, the more pixels the more detail.
The shutter speed of CCTV cameras is important as a slow shutter speed means subjects in motion will be blurred. The shutter speed needs to be fast enough so the individual frames or images are captured frozen.
Many modern quality CCTV cameras have built in automatic focus software which helps along with using high quality varifocal lenses. This is advantageous as long as they are properly adjusted for the particular location and well maintained
Using cheap cables made of copper coated aluminium can reduce signal quality and adversely affect your images and video quality. So it’s important to purchase the best quality cables and fittings your budget allows.
When it comes to accessing your CCTV cameras footage to increase the quality and clarity of the images and video your cameras can capture.
