CCTV cameras. which is better wired or wireless, and colour or monochrome camera?
this would be for outside a bungalow with moderate street lighting
Wired or wireless? Both have advantages and disadvantages. Let me give you an example. A wired camera needs two things: power and a signal return for the image. Power can be battery, a power supply from mains or solar. GBatteries go flat, power supplies can induce interference, solor does not work at night!
Signal return. Wireless in general uses license free either 1.394GHz (1 channel) or 2.4GHz (4 channels) both are subject to site location, signal reflections, dropouts, interference from other sources electromagnetic. Wireless phones and networks can interfere.
Wired on the other hand needs a physical cable run and might be unsightly. signal deteriorates if the correct type of cable is not used or the distance exceeds recommended specifications.
Colour or monochrome? Colour is good, we all like to see in real life what the colour of a person looks like for example but in reality colour is generally more expensive. Monochrome works better in low light and under sodium lighting (street lights) Bothg cameras may be subject to additional lighting if the camera does not see too well at night. as a rule of thumb, if your eyes cant see it a general colour camera cannot either.
My best advice to your would be to seek professional help from an installer because such a simple question as you posed needs more specific information to be answered properly.
If you want a camera to look outside your door to see who is there, get a basic monochrome wired camera system that plugs into your tv.
