Thank you very much.
*Edit: I just checked the link you posted and there are not items. I guess I have to wait until after Chinese New Year!

The default size is 4mm....2.8 will give you the widest view..12 will be very narrow...it all depends on application..I have been searching around on eBay to see what the prices of Hikvision cameras are going for. I found a DS-2CD2332-I 3MP for a decent price. However, there is an option for lens size, 2.8mm( 4mm,6mm, 8mm,12mm optional). I am guessing it comes stock with a 2.88mm. What is the normal lens size most of the users here use? Do I want the bigger lens to have a wider view or does it not matter?
Thanks!

Hence why sometimes it's better to start with a varifocal cam which can be moved around to different locations to work out the best lens required in each spot.
That was my initial plan but my other half prefers the look of domes after the turrets so mostly domes we went.
Thanks for the clarification.
The vari-focal camera is designed to operate at various focal distances. Does the DS-2CD332-I have the ability to have vari-focol? Are there specific camera models that are vari-focol?
Thanks for hijacking h:Yes I have got 7 x 2732 domes from china. Having major problems. they keep droping off every five minutes or so and come back after about 20 seconds. It happens when connected to NVR or direct. I tried to change the firmware. It was originally V5.2.8 tried to down grade to V5.2.3 but now i can only ping the cam but can not access it.
Any Help?
Yes they are available in the ds2cd2732 as a dome and ds2cd2632 as a bullet. Unfortunately the 2332 isn't available in VF.
I have just got 7 x 2732's from china. All apear to reboot every 5 minutes or so. They had V5.28. Tried to load V5.20 via TFTP but now can not access cameras at all.
Any Help?
