Easily replace your CCTV lens for just £9
This video is for the Galayou Y4 cameras but will apply to the majority of cheaper CCTV cameras on the market.
The plastic lenses deteriorate after 10 to 12 months of use.
The 2.8mm lens originally fitted gives around 110 degs FOV.
The lens can be replaced on its own for £6 but it is so much easier replacing the complete unit. Make sure you carefully focus the lens after the repair is complete.
