TL-SG1005P not getting 1000Mbps
It gets 1000Mbps from the router, but not the cameras, any ideas?
tried multiple cables, cables that work with another POE at 1kMbps

thanks for the reply, the camera does support and I tested the camera along with the cable with an AXIS T8415 Wireless Installation Tool it works fine, when i hook it to the sg1005 it wont supply 1000Mbps which in turn doesnt allow me to use h.264 with the camera, it will still show in image with mjpeg though
What cables are you using? UTP? STP? FTP? S/FTP? Make sure you use shielded cable - at least CAT.5e -, else the switch (any switch!) will not be able to reach 1 Gbps.

Using UTP cat 6 shielded, as mentioned above I have tested the cables with an actual tester used to install these cameras commercially, I feel like I might have just "gotten what i paid for" with this switch and it doesn't truly support 1Gbps, as both the camera and cables work fine with other equipment.

UTP stands for Unshielded Twisted Pair; there is no such thing as "UTP shielded". Shielded cables are either STP, FTP or S/FTP. It's printed on the cables, so you can easily check.
TL-SG1005P is a business-classe device with a switching capacity of 10Gbit/s according to the specs. I never had any problems with business-class switches (and I use plenty of them at customer's sites as well as in my office). They usually perform well as specified in the specs. Maybe your switch is broken, so consider to RMA it.

right i meant to say unshielded which isn't a word I guess auto correct got me :D what I was getting at is I had tried the same cable with other equipment and it was giving 1Gbps speed sorry for confusion. So what you are saying is this switch will not support 1Gbps without using shielded cable?
Thanks for taking the time to reply BTW

@RedKamel, you're welcome.
Yes, cables are the critical point here. Always use shielded cables (CAT.5e is good, CAT.6 even better, but necessary only for 10 Gbps). Try a very short spare patch cable: you could get 1 Gbps over short unshielded cable, too, but it depends on environmental parameters. For more cables in a cable duct unshielded cables will start crosstalking. Even the pairs of wires in the same cable are subject to crosstalking, that's why high quality cables have an anti-crosstalk divider between wire pairs (e.g. UBNT ToughCable Carrier). If a switch detects crosstalking, it slows down speed.
I recommend high-quality DRAKA UC900 S/FTP cable (one braid shield, additional foil shield per wire pair, CAT.7) for indoor use and ToughCable Pro (or TC Carrier, but TC Pro is more flexible, both are CAT.5e) for outdoor use. The latter has an additional ground-wire for grounding outdoor equipment, which is important to mitigate against atmospheric electromagnetic discharges during lightning storms.
BTW, another fact to consider: the specs for TL-SG1005P define 1 Gbps per port (actually 2 Gbps in full-duplex mode, that's why the switching capacity for a 5-port switch needs to be 5x2 Gbps = 10 Gbps). If your network topology is four cam ports with one uplink to the router, the max. bandwidth for all cams is 1 Gbps as constrained by the uplink port. So, each cam gets max. 250 Mbps - not 1 Gbps - when transmitting simultaneously over the same uplink port.
Try a short shielded cable with the TL-SG1005P and make measurements, I bet you will reach 1 Gbps - except your switch is broken, then RMA it.

I'll head out and grab some new cables and give it a try, cheaper than a new switch :D thanks a lot for your time
Good idea, but try the quality with one cable first before buying cables for all cams.
