1. Higher image quality
Megapixel resolution. IP HD surveillance cameras are not limited to analog PAL resolution (about 0.4 megapixels), virtually all new IP cameras are at least 1.3 megapixels.
2. No more "interlace" problems
A major problem with analog cameras is interlacing. As a result, the image becomes blurred during strong movements.
A network camera that uses "progressive-scanning technology" provides crystal-clear images even when there is a lot of movement. For example, a license plate number of a passing car can be read into the recordings.
3. Scalability
IP camera surveillance is scalable from one to thousands of cameras in single-camera increments. No fixed, e.g. 16 channel steps as with digital video recorders.
4. Cheaper infrastructure
Most sites are already equipped with UTP (network) cabling, so additional cabling, an expensive part of a CCTV installation, is not needed. Wireless cameras can be used for hard-to-reach places.
5. System integrability and network convergence
IP surveillance is built around an open, integrable platform. System integration is becoming increasingly important in this regard because access control, heating, etc. are also included. should be able to be effectively integrated.
6. Remote access
Every video source, live or recorded, can be accessed and managed from anywhere in the world, via standard or wireless networks. For example, interfacing with monitoring centers for video verification is easily accomplished.
7. Intelligence at the camera level
Integrated PTZ control, motion detection, event handling, sensor in/outputs, relay output, object tracking, time and date and other built-in functions give the camera the ability to make intelligent decisions about when to send alarm notifications (and at what frame rate).
8. Increased reliability
IP based data transport offers the possibility of image storage in other locations and the possibility of redundant infrastructure, server and data storage! This results in significantly reduced replacement time in case of failure.
9. Better utilization of network and audio
The H264 protocol for image transmission consumes significantly less network bandwidth than with MPEG4/MotionJPEG cameras. An important addition is integrated audio in the individual IP cameras.
10. "What you see is what you get"
With IP cameras, what is visible on the screen is also recorded and played back on playback, unlike analog camera solutions where there is often a big difference between the live image and the recorded image (the "Opspoor Verzocht" effect).
11. Power over Ethernet
This feature (sending power via the Ethernet cable along) eliminates the need to mount power points (WCDs) for all camera locations and makes it easier to use a UPS (uninterrupted power supply) to create a 24/7 system independent of power outages.
12. Simplicity in installation, management and maintenance
Because the cameras are approachable over the network, it is possible to change camera settings remotely, without having to climb up a ladder o an analog camera.i.d.
13. Wireless communication
Wireless video transmission uses standard technologies such as IEEE 802.11x and provides (secure) wireless image transmission and possible access to Smart Phones, PDAs, etc.
