Why Are Security Cameras So Low Quality
In today’s day and age, you can see cameras everywhere you go — even our smartphones have more than one! Aside from being in the information age, people can say we’re also at an observation age. If you think about it, security cameras and surveillance equipment are an ever-present yet often unnoticed part of our lives.
However, there’s something that comes to mind about video security footage. Why is it, despite the technological advancements, that videos from security cameras are always low quality?
A typical CCTV camera footage can be described as grainy, blurry, and always monochromatic. If the primary purpose of security cameras is giving protection against possible criminals, why does it capture things so poorly that people can be unidentifiable unless they come close?
Here are some factors on the performance of security cameras, so you can understand the reason why security footage can’t offer excellent quality.
You get about four cameras and a receiver for a few hundred bucks in your average camera system. With this cost, you can’t expect top-of-the-line cameras. Because they are cheaper, the specifications are not usually the best in class.
2. File Compression
When you think about how long security cameras record, you should remember that it means hours upon endless hours. In many cases, recordings last for weeks before they are transferred, stored, deleted, or overwritten. Because of this, cameras are usually equipped with compressing abilities so that less data space is taken up.
3. Video Resolution
For the same reasons as file compression, video resolution is drastically affected by saving up on storage. If you think about it, a 24-hour recording can amount to 1 TB of video for a basic camera — this won’t be doable for security footage where you need constant recording, saving, transferring, viewing, and reviewing access.
Footage from security cameras might not always be of the best quality, but you cannot deny that they are still critical in keeping your home or property safe. There are factors to consider in ensuring that you get better video quality, or you can always invest in a more expensive yet more technologically advanced security camera system for your needs.
