Cable is definitely needed. Which kind of cables should we use? For small surveillance system, all in one cables are OK. There are 10M, 20M, 30M and 50M for option. We choose the proper length. Of course, the cables complied with RG standard are better. But the common ones are also OK for small surveillance. It is up to you to select affordable ones.
Power supply is an easy question. The unqualified ones can not prevent the interference. But how to distinguish the qualified and unqualified ones? Usually the heavier, the better. Then the more expensive, the better. And we can consult from the seller if these power supplies can prevent interference or not.
We sometimes need video balums. It is a very good device. If we use them, we can save a lot of cables once there are many cameras in the same place. Video balums are simple devices. There are one channel, 4 channels and etc. There was an article which introduced the video balums. The reader can search it for reference.
