The popularization of security surveillance systems has been a key factor in reducing crime rates, as well as, investigation and identification of offenders post any such incidents. A common concern of the individuals planning the installation of CCTV systems at their premises is the camera to choose, IP or Analog. Approach a CCTV camera manufacturer in UK to learn more about IP and Analog cameras.
The IP and analog cameras differ in the video processing technique, clarity of videos, capabilities, and video transmission.
The IP cameras function as both camera and video processors. The Network Video Recorder (NVR) technology integrated into the IP cameras enables the camera to process the video captured before transmitting it to the recorder through an Ethernet cable. It is the ideal choice for areas of any size, with the technology allowing up to 128 cameras in a single connection.
On the other hand, the analog camera doesn’t process the videos. It would transmit whatever was captured to the Digital Video Recorder (DVR). Since the DVR is the component that processes the video images, it has limitations in the number of cameras that can be installed on a single system. You can install a maximum of 32 analog cameras only. The data transmitted through a coaxial cable is poor in resolution compared to an IP camera.
We are listing out some of the most important things to be considered when you go for procurement of security cameras. You must note evaluate the CCTV camera vis-à-vis the peculiarities of the premises, where those will be installed, viz. how large is the area, criticality of the spaces, how important is the systems installed, whether you need both audio and video, etc.
- IP cameras offer high-resolution visuals than analog cameras. Offering the possibility of better zoom, the video footage will help in identifying the individuals. Furthermore, it can be integrated with facial recognition capability as well.
- The Analog camera resolution ranges from 420 to 700 pixels, which is not admirable in this digital era.
- The IP camera is available in both wired and wireless connections. On a wired network, it uses Ethernet cables. A wireless system is not possible in an analog camera. It is connected using coaxial cables.
- The clarity of video signal reduces with distance, in the case of analog cameras. Furthermore, it can send signals up to 3 km only. IP cameras offer transmission of video signals to any distance, without any reduction in quality. The digital transmission makes it possible to view the videos on any device. This helps in viewing the real-time videos even while on the move.
- Analog cameras are cheaper than IP cameras. This has been the reason for those with budgetary constraints to opt for the same. However, you would be sacrificing quality, usability, efficacy, etc.
- The IP cameras can be integrated with motion sensors for automatic activation in case required. Additional functions such as pan, tilt, and zoom can also be automated.
- Single Ethernet cable is sufficient for all the purposes on an IP camera, i.e. the power input, video and audio output, and PTZ control can be facilitated through the single cable. The analog camera would require a set of cables. Each for different purposes like power supply, PTZ, audio, and video.
- It is comparatively easy to steal the video footage, damage the devices and tamper the videos in the analog camera system. The video signal from the IP camera is encrypted, making it difficult for the intruders to play with those.
- Both IP and analog cameras are reliable. Nonetheless, IP cameras have better backup systems than analog cameras.
- IP cameras are scalable systems. It can be incorporated with innovative digital solutions and novel technologies.
- The cost of IP cameras has been higher than analog cameras. But, with the increased popularity of IP cameras, the cost has started dropping. The overall installation costs will not be much higher than the analog camera system, considering the expenses for cabling and other associated activities.
We have undertaken an all-encompassing analysis of both IP and Analog cameras. Viewing the increasing security concerns and the requirement of compatible and advanced digital systems, we believe that IP cameras would be the right option. The boundless advantages offered by the IP camera system nullify the high expenses towards the installation of the same.
Go for innovative technology, rather than adjusting with the old. Choose IP cameras for installation at your premises. It would ensure a safe and secure industrial, commercial and residential space.
