Hi Andy, I'm looking to buy (to dleiver to melbourne) 6 x IPC-HFW1831-E (or perhaps varifocal version IPC-HFW2831T-ZS ) but I notice there is not much stock in your aliexpress store (haven't checked your other stores). Can you quote & advise when available? (I'd need 3 x 2.8mm, 2x 4mm, 1x 6mm lens). I will also need 9ch PoE NVR, and 5x wall mounts & 1x ceiling mounts - please quote if you can.
