Greetings from a retired Englishman living in Thailand. I'm not a bot 
Good site this, Thanks
I have the opportunity to buy two Dahua DH-IPC-HFW2449M-S-PRO 1/1.8" (doesn't say focal length) and one DH-IPC-HDW2449T-S-PRO 1/1.8" (2.8 mm) from an authorised Dahua retailer with full Dahua Thailand 3 year warranty for USD 248 including freight. I find that to be a very good price in Thailand. Normal price is USD 350.
Are they any good? For USD89 each? Old model? What's the catch?
Thank you
Michael
