Thanks for the response. I have a LTS DVR MOdel LTD411M6 4 channel unit. The 1/3 camera I bought on ebay. The 1/4 cameras have no markings denoting make or model. They look very similar to the 1/3 one but are a bit smaller. The specs on the 1/3 (the more blurry one) are:

I just want some cameras that show a clear image, both day and night. Hopefully they aren't too expensive. If necessary, I'll buy them one at a time as I can afford them. I just bought a 9 channel Dedicated Micros DVR and am awaiting its arrival. I like the 9 camera option, and as I understand it, I'll have more control from a remote computer. Any help or advice you can give me will be greatly appreciated. Jim
