Dome security cameras are named after their dome-shaped housings, which are built to withstand the elements. Dome CCTV cameras are commonly employed both inside and outside the home, on ceilings, in retail stores, and hotels, among other places.
Because of the dome shape, it's nearly impossible to discern which direction the dome surveillance camera is truly pointed (particularly for potential thieves or burglars).
What are the advantages of a dome camera?
Vandal Resistant:
If cameras are to be positioned in places that are prone to tampering or vandalism, vandal-proof dome cameras should be used. Many dome cameras have vandal-resistant ratings (such as IK08 and IK10) that indicate how well they are protected mechanically. Because these security cameras are sealed and need special tools to disassemble, they are impossible to tamper with once they are installed.
Weatherproof:
Many outdoor dome cameras are waterproof and water-resistant, allowing for continuous surveillance regardless of the weather. IP65, IP66, and IP67 are common ratings for outdoor dome cameras. Many security providers offer outdoor domes with built-in temperature meters and heaters, allowing cameras to work in freezing temperatures.
High Resolution:
The resolution of a dome camera varies depending on the make and type; nevertheless, most vendors provide dome cameras with very high resolution. Many modern video security solutions include dome cameras with a 3MP (2048 x 1536 pixel) sensor, which can record up to 50% more detail than 1080p and come in a variety of sizes ranging from 2 to 6 megapixels.
Monitor at wide angles (Varifocal Lens):
Varifocal lenses on dome cameras give a changeable focal length, allowing teams to set the camera lens to the desired distance. Because the lens can move due to the dome's form, monitoring can be done from a broader angle.
Discrete Positioning:
Onlookers may find it difficult to tell the direction of the camera lens from a distance due to the dome cover. This makes it difficult for burglars to guess which areas are being monitored without getting close to the camera, making it an efficient crime and vandalism deterrent.
Night Vision (Built-in IR Illuminators):
Infrared (IR) illuminators and a progressive CMOS sensor are standard features on many dome cameras. This combination allows unrivaled low-light camera performance for indoor and outdoor applications at ranges of up to 30 meters.
Conclusion
Despite the numerous advantages of dome cameras, any outdoor camera that is not well kept can quickly become dusty and a possible hub for spider webs, necessitating frequent maintenance and cleaning on the surface of any security camera to extend its lifespan.
