Network IP security cameras transmit video over ethernet or WiFi — offering resolutions from 2MP to 4K+, AI-powered analytics, remote access from any device, and Power over Ethernet (PoE). Available in dome, bullet, turret, PTZ, fisheye, and panoramic form factors for commercial, industrial, and institutional facilities.
A network IP security camera is a digital camera that transmits video over an IP network (ethernet or WiFi) rather than a coaxial cable. IP cameras offer higher resolution (2MP to 4K), remote access from anywhere with internet, AI analytics, and integration with NVR systems and cloud storage.
A complete IP camera system requires: IP cameras, a Network Video Recorder (NVR) or cloud storage, a PoE switch (to power cameras via ethernet cable), and a router for remote access. Most modern systems only require running a single ethernet cable per camera.
IP cameras transmit digital video over ethernet at resolutions up to 4K. Analog cameras transmit lower-resolution video over coaxial cable. IP cameras support remote access, AI analytics, PoE power, and easy scalability. Analog systems are lower cost but limited in resolution and features.
Commercial IP camera types include: dome cameras (ceiling mount, vandal-resistant), bullet cameras (outdoor, long-range), turret cameras (flexible positioning), PTZ cameras (pan-tilt-zoom, remote control), fisheye cameras (360-degree coverage), and box cameras (interchangeable lenses for specialized applications).
A 4MP IP camera at 15fps with H.265 compression uses approximately 15-20 GB per day. A 16-camera system needs 250-320 GB per day, or 1.75-2.25 TB for 7-day retention. NVR systems from 4 to 128 channels with 2TB to 20TB storage are available from 2M Technology.
Power over Ethernet (PoE) delivers both power and data through a single ethernet cable, eliminating the need for a separate power supply at each camera location. Most commercial IP cameras draw 7-25 watts over PoE, requiring a PoE+ (802.3at) switch rated for the total camera power budget.
Yes. Most IP cameras include infrared (IR) LEDs for black-and-white night vision at ranges of 30-200+ feet. Starlight and color night vision cameras use large sensors to produce color video in near-darkness. Thermal cameras detect heat signatures and work in complete darkness regardless of lighting conditions.
ONVIF (Open Network Video Interface Forum) is an industry standard that ensures interoperability between IP cameras and NVR systems from different manufacturers. ONVIF-compatible cameras can be integrated with any ONVIF-compatible NVR, giving you flexibility to mix brands and upgrade components independently.
