anyone recommend me a good 8 port gigabit switch for hikvision 3mp cameras? need poe on all the 8 ports preferably, and not cost the earth.
 
The problem with that switch is that it only has 8 ports and you need one port to uplink to the network...so you will only have 7 usable ports...
 
I have a Zyxel ES-2108PWR. It has 8 10/100 PoE ports and 1x GigE uplink (copper or fiber). It is a managed switch, I found it for $100 as a refurb.
 
I'm still trying to get over the look of having the cables come in and out the rear instead of the front.

another question, if I connected a gigabit POE switch to a normal gigabit switch with a network cable to connect them together, it wont blow either up will it? with one supplying power and the other not to the port?
 
Yes, PoE will only send power if it requested by the device. Otherwise the switch just interacts with it as if it were a regular switch.

Also: Some switches support powering down the POE part on switch ports if necessary. This might be useful if you want to reboot a device. You can also leave the power off to said port.

The 802.3af POE standard is designed to safely allow 'mix and match' of POE and non-POE equipment.
The 'power supplying equipment' will not enable any power until the 'power using equipment' requests it via a specific method - which is applying a specific resistance between 1 of the cable pairs to signal a POE device and a bit more besides, a form of handshaking.
So the answer to your question is 'no, the POE switch won't blow up a non-POE device'.
 
If I recall correctly the default setting for video is at 4096kbps. With 3 cameras you are at 12,288kbps (~12mbpts). So a 100mbps is plenty enough even after subtracting some overhead and variances.
 
I use a Trendnet TPE-S160. I got a pretty good price ($65 incl. shipping, used, pretty scratched up but working) and frankly would not pay the full price. The switches others mentioned sound pretty reasonable. If you need 8 PoE ports and have an 8 port PoE switch (1 short because of the uplink) and you don't plan to add more cameras, then you might consider purchasing a PoE injector for that one additional camera.

Also note that most PoE switches are limited to ~15W per port. In addition, the total wattage available might be less than #PoE ports * 15W. This should not be an issue with most cameras but an outdoor PoE camera with PTZ (Pan Tilt Zoom) might consume more than that.
