Hi, I would be thankful if someone guides me on the situation: 
  
There is GAS station of my client with 4 machines (filling machines) 
Recently client's employee was robbed. (in my country client stands near to filling machine and collects cash) 
  
I want outdoor day/night solution. I tried outdoor 50M, 420 TVL with 12mm lens. 
Is it appropriate solutions? or box with lens can work there 
  
* if client goes for 420+tvl solution , its is out of budget!
