the budget is ok but do want to keep it reasonably low
As suggested by others it really depends on what is the type of traffic will be flowing across the network, as per the post if it is prely a video traffic fo low cost camera can be given power from switches itself, so with requirement of video traffic in mind i would suggest check the data sheet for cisco 3560 with POE feature.
If your cameras are PoE, I think 2960 with PoE would do the job. If the distance between the closet and the data center is more than 100meters, then you'd better consider SFP slots for fiber uplink connections. check Cisco datasheets for more information:
You have to have some idea on how much traffic is going to be passed across the network. If the users are light office users then access switches could be 2960's going back to a 3560 or 3750 core. If they are heavier users then you could use the 3560's as access switches and something more powerful at the core like 4500's . If you only have 4 closets and not real high density requirements then use the 2960 scenario , even with these you can get a stackable 2960 now to have the ability to add in the future .
My personal experience, I would go with the 3750 model, as a basic lan switch. They are easy to manage stackable (up to 9 physical switches) and support a vast array of featues (if you actually need them). You manage the switch stack from only one ip address.
