Early Days of Surveillance

In the early days of surveillance, security cameras used analog technology to record video footage. These cameras were typically bulky and required manual operation. The video recordings were stored on VHS tapes, which had limited storage capacity and were prone to degradation over time.

Security personnel had to physically change the tapes regularly to ensure continuous recording. The image quality of these early security cameras was often poor, with low resolution and limited color reproduction.

Despite their limitations, these early security cameras played a crucial role in deterring crime and monitoring public spaces. They laid the foundation for the advanced digital surveillance systems that we use today.

Technology Limitations

Security cameras from 20 years ago had several limitations compared to modern systems. One of the main limitations was the video quality, which was often much lower resolution than what we have today. This resulted in grainy and blurry footage, making it harder to identify individuals or details in the recording.

Another limitation was the storage capacity of the cameras. With limited storage options, older security cameras could only record for a short period before overwriting old footage. This meant that important events could be missed if the system was not constantly monitored and footage saved manually.

Additionally, older security cameras were usually connected via analog cables, which limited the distance they could be placed from the recording device. This restricted the coverage area of the cameras and made it difficult to install them in large or remote locations.

Overall, the technology limitations of security cameras from 20 years ago made them less effective in capturing and storing high-quality footage compared to the advanced systems available today.

Recording Methods

Security cameras 20 years ago primarily used analog recording methods. The most common method was VHS (Video Home System) recording, where the camera’s video feed was directly recorded onto VHS tapes. These tapes had limited storage capacity and required frequent changing to ensure continuous recording.

Another method was using DVRs (Digital Video Recorders) that could store the video feed digitally on hard drives or other storage media. However, DVRs were not as common or advanced as they are today, and the video quality and storage capacity were limited compared to modern systems.
