Common Misconceptions
Misconception 1: Footage in CCTV is always clear and high-definition
One common misconception about CCTV footage is that it is always clear and high-definition. However, this is not always the case. There are several factors that can affect the quality of footage, such as the placement of cameras, lighting conditions, and the overall quality of the CCTV system.
- The placement of cameras can impact the view and clarity of the footage.
- Lighting conditions, such as low light or glare, can make the footage less clear.
- The quality of the CCTV system itself plays a critical role in determining the clarity of the footage.
Misconception 2: CCTV footage is always recorded in real-time
Another misconception is that CCTV footage is always recorded in real-time. While some systems offer live monitoring and recording, many CCTV systems record footage for later review rather than providing real-time monitoring.
- Not all CCTV systems have live monitoring capabilities.
- Recording footage for later review is often more cost-effective and efficient.
- Real-time monitoring may require more advanced and expensive systems.
Misconception 3: Once recorded, CCTV footage can be easily enhanced like in crime TV shows
Many people believe that once CCTV footage is recorded, it can be easily enhanced and enlarged, just like in crime TV shows. However, the reality is quite different.
- Enhancing and enlarging footage beyond its original quality is often not possible.
- The resolution and details captured by the cameras initially limit the potential for enhancement.
- CCTV footage is not magically enhanced like depicted in fictional shows.
Misconception 4: CCTV cameras can see and record in complete darkness
It is a common misconception that CCTV cameras can see and record in complete darkness. While there are infrared cameras that can capture images in low light or darkness, these cameras have limitations.
- Infrared cameras have a limited range and may not provide clear images in complete darkness.
- Extreme darkness may result in grainy or distorted footage.
- Additional lighting sources may be required for capturing clear footage in dark environments.
Misconception 5: CCTV footage is always stored for an indefinite period
Lastly, there is a misconception that CCTV footage is always stored for an indefinite period. While some systems may be designed to retain footage for extended periods, many systems have limitations on storage capacity and retain footage for a limited duration.
- CCTV systems often have a specific storage capacity or retention period for recorded footage.
- Storage limitations may lead to the automatic deletion of older footage to make space for new recordings.
- Retention policies are often dictated by legal requirements and organizational needs.
