Can you expound on what defines a 'cheap camera'? (other than the price)
What technical specifications do you recommend?
Good cameras start in the 200 dollar range for an analog and and a little more for an IP based camera. The prices easily triple that for commercial versions.
Analog cameras will be cheaper and easier to install but will be limited on quality and require either a stand alone recorder or a capture card in a computer.
Ip cameras generally are more expensive and require a base knowledge of computer networks to install. The quality generally ( unless you are buying a oober cheap model) begin quality where analog leaves off. stand alone recorders can be found but generally a computer with software is used to record and view video. recording-playback of streamed video is hardware intense and is not well suited for a laptop. Dedicated computers are desired if not mandatory if you are doing more then one camera (MEG). IP cameras are generally easily streamed to remote devices like Iphones
At a minimum I'd look at Speco Intensifier series cameras for analog and Vivotek for IP
