What is the main problem with CCTV?
With CCTV cameras, a lot of things could go wrong. The camera is at the heart of many problems with CCTV systems. The good news about this is that figuring out what the issue is and how to address it is typically not too difficult. The majority of CCTV issues manifest as some sort of characteristic on the screen. Six of the most prevalent CCTV camera issues will be covered in this article. Hence ICFix Service provides CCTV training courses in Chennai.
Burnt out sun:
Most people think there isn’t much you can do to a camera that is rated for use outside to cause it to malfunction. That is not the situation. Sunburn is among the most prevalent of these issues. When the camera is pointed in a way that light rays penetrate the lens and strike the image sensor, this issue arises. This causes the image to get distorted over time. Issues like a shift in contrast and blurriness of the image are caused by this issue. The majority of people are familiar enough with cameras to know not to point the lens directly at the sun.
Conductivity of electricity:
The majority of skilled installers are aware that mounting a camera on a metal surface is never recommended. Electrical current can occasionally surge and spill when it comes into touch with a metal surface, especially if the camera has been wired incorrectly. Because of this, if your camera isn’t correctly insulated, the current will enter the device and result in lines and image distortions.
Floor loops:
When two pieces of equipment have several ground connection paths, a ground loop happens. Ground loops can seriously harm your CCTV system. Humming, noise, and other interference with devices like computers, televisions, and other equipment are a few of these issues. Ground loops are frequently caused by defective cables or the power supply of CCTV cameras. This issue can also be brought on by improper wiring in the structure to which a camera is attached.
Different recording technologies:
NTSC and PAL are two fundamental yet quite dissimilar recording methods. Your country will either have one or the other, depending on where you reside. You will recognize right away if you plug in a system that is inappropriate for the nation you are in. There will be mostly black lines on your screen.
IR filter absent:
IR filters, also known as infrared cut filters, are made to keep visible light waves in while removing infrared light wavelengths from your camera. If you buy a cheap camera, there’s a strong possibility it won’t include this filter, so be careful and get ready to be disappointed in the image quality. Without an IR filter, your image will be extremely bright, and no matter how hard you attempt to balance the brightness, you won’t be able to.
Power source:
Typically, lines that roll from bottom to top on your screen indicate power supplies that are incompatible with your equipment. When you notice rolling lines, don’t immediately assume that there is a power supply issue because it’s fairly uncommon to also see rolling lines that run from top to bottom. The image won’t move when this issue arises, but the lines will keep rolling. Similar to a ground loop issue, except with a power supply issue the lines roll as opposed to a ground loop issue where they remain stationary.
