maybe you got the fake module products, can you post their company name? now CMOS moudle with IR-CUT filter can get good image than same TVL CCD, in the meanwhile the price is cheaper than CCD. waltertopband
hi friend, you can try TBO-2056R, with ex-view CCD, even the low light can see the plate clearly.
the height 62mm, you add a bracket and a housing, won't over 200mm.
