Running IP Cameras Over Existing Cat3 - Will It Work?

We are dealing with a legacy analog system that was installed using 4-pair Cat-3 and video baluns. The customer wants to go IP.

My research suggests that we should be able to use standard switches and cameras as long as both support 10BASE-T. Standard PoE is supposedly supported over Cat-3 as well (PoE+ is not). We have gone through and certified most of the lines (10 out of 16 - the remainder require a lift), and all of them have passed certification.

My next step would be to test a single camera and the intended switch before committing to a price with the customer. Am I being overly cautious here? It really seems that since we passed certification everything should "just work", but I have never used Cat-3 for cameras.
