To compensate for this, some security systems opt for lower resolution cameras to maximize storage capacity.
Compatibility: In some cases, security cameras need to be compatible with existing surveillance systems, which may have limitations on supporting higher resolution cameras. This can result in using lower resolution cameras to ensure compatibility and avoid the need for extensive system upgrades.
Adequacy for Surveillance Needs: In certain situations, lower resolution cameras may be sufficient for their intended purpose. For example, if the cameras are mainly used for monitoring general activity or detecting motion, a higher resolution may not be necessary, making the use of low-resolution cameras more practical.
Power Supply Constraints: Security cameras rely on power supplies to operate, and higher resolution cameras tend to require more power. In environments where power supply is limited or difficult to install, lower resolution cameras may be preferred due to their lower power consumption.
Objective of Surveillance: Depending on the objective of the surveillance, lower resolution cameras may be used deliberately. For instance, in certain scenarios where the primary aim is to deter potential intruders rather than capturing highly detailed footage, low-resolution cameras may be deemed sufficient.
While the low resolution of security cameras may be a limitation in some cases, it is important to consider these reasons and requirements when choosing the appropriate system for specific surveillance needs.
Limited Bandwidth and Storage Capacity
One of the main reasons why security cameras often have low resolution is due to the limitations of bandwidth and storage capacity. High-resolution video requires a significant amount of bandwidth to transmit the data from the camera to a storage device or monitoring station. However, most surveillance systems have limited bandwidth available, especially in situations where multiple cameras are being used simultaneously.
The limited bandwidth means that higher-resolution video would require more data to be transferred, leading to slower transmission speeds and potentially causing delays or interruptions in the video feed. To avoid this issue, security cameras are often designed with lower resolution settings, which require less bandwidth to transmit the video stream.
In addition to limited bandwidth, storage capacity is another consideration that influences the resolution of security cameras. Higher-resolution video takes up more storage space, and surveillance systems often have finite storage capabilities. By using lower-resolution cameras, the amount of storage required is reduced, allowing for more video footage to be stored for longer periods.
This compromise between resolution and limiting bandwidth and storage requirements is critical in ensuring that security cameras can function effectively within the constraints of the system. While this may result in lower-quality footage, it allows for smoother video transmission, longer storage times, and better overall performance of the surveillance system.

| Lower bandwidth usage | Lower image quality |
| Longer storage times | Limited ability to zoom or enhance footage |
| Reduced transmission delays | Less detailed facial recognition |
Cost Constraints and Budget considerations
Security cameras are often low resolution due to cost constraints and budget considerations. When deploying a surveillance system, the number of cameras required can be significant, especially in large areas or buildings. Each camera needs to be purchased, installed, and maintained, which can quickly become expensive.
High-resolution cameras typically have higher costs associated with them, including the camera itself, storage for the recorded footage, and the required network infrastructure. These additional expenses can add up quickly, making it more difficult for businesses or homeowners with limited budgets to invest in high-resolution cameras.
By using low-resolution cameras, organizations can save money while still having a basic level of surveillance coverage. While the image quality may not be as clear or detailed as with high-resolution cameras, low-resolution cameras can still capture important details such as facial features or identifying characteristics.
In addition to the initial cost savings, low-resolution cameras also require less bandwidth and storage space. This can be beneficial for organizations that have limited network capabilities or want to minimize the amount of storage needed to retain the recorded footage. It is often more cost-effective to invest in additional low-resolution cameras rather than investing in high-resolution cameras and the associated storage infrastructure.

Insufficient Lighting Conditions
One of the main reasons why security cameras often have low resolution is due to insufficient lighting conditions. Many security cameras are installed in outdoor environments where there may not be adequate lighting, especially during the night or in low light situations.
Low lighting conditions can lead to grainy and blurry footage, as the camera sensors struggle to capture clear images. The limited amount of light available makes it challenging for cameras to produce high-resolution videos. This is especially true for older or less advanced cameras.
Security cameras rely on light to capture clear images and videos. Inadequate lighting can result in dark and shadowy areas in the footage, making it difficult to identify people or objects. This is a significant limitation when it comes to ensuring the effectiveness of security cameras in monitoring and identifying potential threats.
To overcome the limitations of insufficient lighting conditions, some security cameras are equipped with infrared technology. This technology emits infrared light, which is invisible to the human eye but can be detected by the camera sensors. Infrared lighting helps improve the clarity of images captured in low light conditions, allowing for clearer surveillance footage.
However, even with advanced technologies like infrared lighting, the resolution of security camera footage may still be affected by the lighting conditions. In cases where the lighting is extremely poor or non-existent, the footage may appear dark and pixelated, making it challenging to gather useful information.
Overall, insufficient lighting conditions play a significant role in the low resolution of security camera footage. As technology continues to improve, cameras with better low light performance and higher resolutions are being developed, but it is still crucial to ensure adequate lighting for optimal security camera performance and image quality.
