The actual hardware cost of these devices is actually minimal. Basically any wifi capable microcontroller, a camera and depending on implementation some storage (or a micro sd-card holder). So that price is only cheap in comparison to existing products.
For reference, said microcontroller with basic camera can be had for like 3$ or something.
