I actually already have a gadget that works like a CCTV camera which you can access from your smartphone. Although the price is quite reasonable compared to other complicated CCTVs, It will still cost as much as a new cellphone.
The thing is, there is now an easier way to get this type of service. No need to buy expensive and complicated CCTV cameras. All you need to do is get a PLDT HOME FAM CAM!
