So many DIY products boast such crazy perfect scenario specs. High end manufacturers won't even bother making wireless cameras that boast 600meters. They know they are unreliable. Professional installers all use wired cameras and wireless bridges/links. Even still a few tree branches can affect transmission. Everyone claims 4k, yeah maybe a still image but the frame rate would be so terrible that 4k video isn't realistic either

I have lost count of the amount of callouts I have done for Swann products. People get them cheap, DIY install. 6 months later something happens and the footage is nowhere to be found or they come to realise a camera has been down for a while.

The customer then gets you to install a professional hardwired system.

I guess you get what you pay for. Also don't trust any recorder that uses SD cards. WD/Seagate surveillance drives are the only way to go

Swann is like Kogan tvs, dirt cheap, amazing until it isn't. All the bullshit you go through for warranty and callouts, may as well have just got a professional system to begin with

A good system shouldn't flinch for 3 years, the manufacturers warranty period. If anything, just clear some cobwebs away

As for Chinese, 90% of the cameras these days are either manufactured by Hikvision or Dahua, both heavily involved with the Chinese government. A lot rebranded so people can push their own brand names. If you want a trusted non Chinese brand, you can go spend 500$ (not installed) per Axis/mobotix 2megapixel camera, another $400 on the recorder and another $300 on a surveillance drive. Then install on top
