Hello, 
  
I'm thinking about upgrading my current shambles of a CCTV system and I have about £400 to spend. 
  
I have three cheap unbranded cameras from my FPV days and an unbranded 4-ch DVR I bagged off ebay, in total about £40 worth including an HDD pulled from the bin. Despite the low cost the lot has worked surprisingly well for the last three years; 
  
- The lot runs through existing CAT5e cables (via baluns), I wired the house with cat5e when I moved in 
- I can view the individual cameras very quickly via RTSP, using VLC and a shortcut on the computer desktop 
- Reviewing footage over the DVR's web interface is easy enough, but I don't like the activeX component requirement 
- I don't trust the DVR's security, I've effectively blocked it from the web and off-site access is over VPN only. 
  
My objectives; 
  
- Improve video quality [EDIT: Will certainly need new cameras] 
- Initial 2 camera requirement, additional camera capacity welcome but not required 
- Enable access over smartphones, e.g. good app support. 
- Retain quick individual camera stream access using VLC or similar 
- Utilise existing CAT5e wiring 
- Ease my security concerns 
  
So, what can you suggest? 
  
Thanks!
