First answer these questions -
Have a look through the CCTV kits we sell, this will give you an idea of what you will need for a complete cctv system and how much its likely to cost. As with most thing, the more you spend the better the quality tends to be. If you have an existing system, then an upgrade maybe a better option.
Hikvision are industry leaders, with the latest and greatest technology. They offer great reliability with longest Guarantee (from 3 to 5 years), but come with a higher price tag.
HiLook are made by Hikvision and use the same app and user interface. The HiLook range is aimed at those customers on a budget. The quality is not the same, HiLook a budget option.
Qtron are our rebranded range. They offer great value for money with IP cameras being about 30% cheaper than Hikvision. Picture quality is not as good as Hikvision but still comparable. Qtron IP is plug and play with Hikvision recorders and the user interface is very similar. Qtron IP in general is cheaper than HiLook IP with better picture quality.
