UNIVIEW DOME EASY4MP 2.8MM 30M IR Dome Camera
The UNIVIEW DOME EASY4MP 2.8MM 30M IR is a dome camera for video surveillance. It combines a 4 megapixel image sensor, a fixed 2.8 mm lens and an infrared illuminator with a range of about 30 metres. It is intended for customers who need clear recordings of a monitored area, both during the day and at night.
Key features
- 4 MP (megapixel) resolution for detailed images
- 2.8 mm fixed lens with a wide viewing angle
- Infrared night vision with a range of 30 m (30M IR)
- Dome housing for a discreet mounting appearance
- Suitable for indoor and outdoor surveillance setups as part of a CCTV system
Image quality
A 4 megapixel sensor captures roughly four times the detail of a 1 megapixel camera. This matters when footage needs to be reviewed later, for example to read a number plate, recognise a face or follow the movement of a person across a larger area. The fixed 2.8 mm lens suits general overview monitoring. Because the focal length is short, objects at close range fill more of the frame, while distant subjects appear smaller, so the camera is best placed where the area of interest is within a reasonable distance.
Night-time performance
The built-in infrared illuminator lets the camera record in darkness. Infrared light is invisible to the human eye, so the monitored area is not lit up in a way that might disturb neighbours or staff. The stated illumination range is 30 metres. Actual performance depends on the surface reflectivity, obstacles and the mounting position, so it is a good idea to test the view on site before finalising the installation.
Installation
Dome cameras are usually mounted on ceilings or walls. The dome cover protects the lens from dust and minor impacts and hides the direction the lens is pointing, which many users find useful. Plan the cable route and the power supply before mounting. Check that the mounting surface is firm and that the camera can be aimed at the area of interest. Follow the installation guidance supplied with the product and the requirements of your recording system.
Typical uses
- Monitoring entrances, lobbies and reception areas
- Covering corridors, stairwells and storage rooms
- Observing car parks, yards and building perimeters at night
- Surveillance in shops, offices and warehouses
- Residential and small commercial security systems
Who it is for
The camera is a good fit for installers, facility managers and property owners who want a consistent, unobtrusive camera for general surveillance. Because the dome form factor is widely used, it is easy to combine with other dome cameras in the same system for a uniform look and simpler maintenance.
For the best results, select a recorder or network video system that supports the camera’s resolution and that can store the expected volume of footage. Consider the number of cameras, the retention period you need and the bandwidth of the network. Clean the lens periodically and check the camera after storms or heavy weather to confirm that the image remains clear.
