Most of our clients have been asking us the difference between IP and analogue CCTV systems. In this blog post we will break it down for you.
Analog refers to CCTV cameras which use an analog video signal that is transmitted over coaxial cable back to a video recorder or monitor.
IP Cameras refers to digital CCTV Cameras connected together over a computer network.
1. Picture Quality
The best analog camera has a worse image resolution as compared to the worst IP Camera. IP cameras capture a much wider field of view than comparable analog cameras, meaning a single IP camera is potentially able to do the job of three to four of the analog cameras.
2. Video Analytics
It is easier to analyze video footage from IP Camera networks than from analog networks. This could be anything from motion detection to missing objects to tampering with the camera itself. Instead of poring over hours of footage, your network can tell you exactly when these events occurred and point you right to them.
3. Flexibility and Scalability
- Less cabling work for IP Networks
- Better scalability for IP networks through the use of switches
In a traditional analog DVR set-up, each camera must be connected directly to the DVR. IP cameras can circumvent this through the use of switches, which allow cameras in close proximity to each other to be connected to a single switch, which then runs a single wire to the NVR (Network Video Recorder).
This reduces the amount of cabling runs, which makes it ultimately less labor intensive, and also allows you to connect more cameras because you're no longer limited by the number of ports on your DVR.
4. Power Supply
For IP Camera systems, using a PoE (Power over Ethernet) switch allows A Cat 6 cable to run the signal and provide power to the cameras, eliminating the need for a separate power supply. Analog systems on the other hand require the use an external power supply source.
5. Digital Recording
Analog systems use a Digital Video Recorder (DVR) while the IP Camera systems use a Network Video Recorder (NVR). The main difference between the two is that you can connect more cameras to an NVR than to a DVR with the same number of channels.
IP Cameras are typically pricier than analog cameras. For many people, the benefits that come with such cost makes it a worthy investment.
