The ideal option for using your monochrome analog camera with LabVIEW is to use a National Instruments image acquisition card (frame grabber). Every image acquisition card requires a board-level driver to talk to the hardware. NI-IMAQ is the hardware driver that is used with all National Instruments frame grabbers. When NI-IMAQ is installed it also puts a set of LabVIEW VIs in the functions palette. These VIs do not themselves constitute a "driver", but rather are simply wrappers for function calls to the NI-IMAQ driver. Basically the work of calling DLLs within LabVIEW is done for you. There are also countless other benefits of using a National Instruments frame grabber and driver - such as a wealth of example programs, documentation, and technical support to name a few. The most cost effective frame grabber that National Instruments makes is the PCI-1407:NI PCI-1407: Single-Channel, Analog, Monochrome Acquisition The price is beyond your budget, but may be worth considering.
If you are not tied to that analog camera, another option would be to use a firewire camera with a firewire card and the NI-IMAQ for IEEE 1394 driver.
NI-IMAQ is not designed to be used with other company's frame grabbers, but every frame grabber manufacturer has a driver designed for their own hardware. There are companies out there who have created their own LabVIEW VIs to make calls to their own hardware driver, with varying degrees of success. For example, at one point a company called Image Mill Technology offered LabVIEW VIs to access Matrox's framegrabber driver, called MIL-Lite.
I do not know if Sensoray has LabVIEW VIs for their driver, but you might ask. If not, you would need to make calls to their DLL from LabVIEW. Here is a document that may help get your started:

I hope this helps! Good luck.
