As with digital still cameras, the resolution of IP cameras has increased with time. Megapixel IP CCTV cameras are now available at resolutions of up to 16 megapixels. Today there are several manufacturers of IP cameras. IP surveillance equipment vendors include both specialized digital imaging equipment manufacturers and larger manufacturers that are active in consumer, broadcast, and security video.

Cost advantages include; reduced system cost and added functionality due to general-purpose IP networking equipment infrastructure.

Lower cost of cabling in large installations (CAT5e instead of RG-59 coaxial cable).

Reduced space requirements in large (many camera) CCTV setups because video switching and routing is done via computer and does not need physically large and expensive video matrix switchers.
