It’s helpful to understand the advantages and disadvantages of PTZ cameras. Here is a list of PTZ camera cons or disadvantages.
Limited View
PTZ cameras have limited coverage, as they cannot record areas the camera isn’t specifically looking at. They do not pan, tilt or zoom automatically to cover potential gaps in surveillance unless manually programmed with specific settings beforehand – leaving an opening for intruders who may slip by unnoticed.
Shorter Lifespan
PTZ cameras are more expensive and less durable than fixed solutions. They have a higher failure rate because they contain many moving parts for pan, tilt, and zoom functionality.
Surveillance Blindspots
Since PTZ camera movements are often preset, this can lead to blindspots if left unattended. Surveillance blindspots are almost unavoidable even when PTZ cameras are manned by security staff. It’s challenging to have all fields of view (FOV) covered.
High Cost
Using a fisheye camera for surveillance can give you the coverage you require at the lowest possible cost.
Latency Sensitivity
Control or command latency could be a problem in PTZ cameras, especially if they are a long distance from their control center (increasing lag time).
High Risk of Malfunction
Mechanical or human install or control errors can lead to legal ramifications. It’s essential to install PTZ cameras properly to ensure their proper function, especially in unpredictable weather conditions.
