A surveillance system is well known that dramatically increases the safety & security of a property. However, placing the security cameras in the right place is just as important as having them. Strategic placement of CCTV cameras will capture clear footage without damaging the video quality.
In this article let’s delve into things that affect the security camera range:
- Location & Distance
- Focal length & view
- Quality & Specifications
Location & Distance
Most people consider placing the cameras at the highest point of their premises to get a wide view, but it will not give detailed look and not able to identify the intruder in case of any criminal activities. Also, the wireless camera’s signal strength will be weaker that affect the visual quality.
Focal length & view
The focal length is another important factor and it refers to the size of the camera lens and its effects on the view. A smaller focal length gives a wider field of view, but objects will appear smaller, and a bigger focal length will cause a narrow field of view, but objects seen as bigger and closer to the camera.
Consider to following the most common lens types:
- 8mm for a 90° view – This lens is the most popular choice for a static camera surveillance system. This lens can cover a wide area with just one camera.
- 4mm for a 60° view– This lens is similar to 2.8mm, but the main difference is the reduced angle of view. It is mainly useful for identification & detection.
- 6mm for a 45° view– This lens is most preferred for monitoring the doorway, corridor, and car park. It gives a detailed distance view.
A wider view allows better coverage to see more things, but it degrades the visual quality. That’s where resolution plays its part in the range of security cameras. A higher resolution has higher pixels and in turn, results in more clear & clarity of the image. Also, you can get a clear view even if the object is far away.
Quality & Specifications
The last and final deciding factor in the range of security cameras is quality. Quality directly correlated to specifications of the camera that totally depends on the objective and application. For example, if you want to use the camera outdoors, then the low light specification is important.
Important specifications to consider in CCTV security camera:
- HD camera
- Minimum illumination
- WDR (wide dynamic range)
- Frame rate
- Input and output (I/O)
