I have a site running a pelco 6800 matrix with a KBD300A keyboard. The keyboard went faulty after a few months and has been in for repair for atleast 3 months. My supplier is unable to get the required chip from Pelco. This has been a problem for some time and I would like to know of a suitable replacement keyboard. I have a samsung SCC3100. Is there any way of controlling the Pelco matrix with the samsung keyboard?

I have a sight about 1km from the sea. Im using speed domes mounted on 11 meter concrete poles. I have been cleaning the cameras regularly, sometimes once a week. Ive tried various products on the market to try and coat the lenses to reduce the visibility problem. Can anyone sugest a product suitable for this application? Thanks
