Hi all. I am thinking of getting some wireless hidden cameras for my house as I do not trust my maid and I will not be home for 10 days next month. I mean by wireless as in it connects over the internet or something so I can live view from my devices. My questions are:

1. Where can I buy them here (KL, Malaysia)? Is there a store/shop that specializes in this?

2. What's the price range?

3. What is a good brand? As usual some brands are better than most depending on specs

4. Should I get those with audio or colour? Obviously the prices for these would be much more pricey compared to those that are b/w no audio

5. Are there battery operated ones? So there is no need to drill or hack the wall for wiring.

As I will be gone for 10 days is there any recommendations? I don't want my maid to know that I have set them up.

Thank you in advance.
