What High Definition (HD) resolution do you need?
At present, the best resolution you can get with HD video surveillance cameras is 1080HD. However, the is a very steep cost premium for 1080 at this juncture. Therefore, I personally recommend to my friends and family 720HD. I have installed 720HD cameras for my home system and they are fantastic. 1080HD provides more clarity but it wasn’t worth approximately 2x the expense for me. Overtime, the cost will come down.
