Shrug, add a nice zoom lens to make it's effective range several meters instead. Of course it would be far sighted but maybe you know most mosquitos will be several meters away anyway. Or have 3 cameras, one for the cm, one for the m and one able to zoom many meters to look at known problem spots like puddles or a bird bath.
Or use a better method than a cheap camera. Like a radar and microphone like the other more famous project does. Because mosquitos have a distinct frequency of flapping their wings. Meaning you can then actually target the biting type. Because .. 95% of the mosquitos around actually do not sting humans(number from the back of my head from a friends paper some years ago). And killing them all has a quite negative impact on biological diversity.
Be sure to include some laser-resistant capabilities in the engineered mosquitoes, so that consumers will be forced to buy upgrades to more powerful lasers.
