If there’s one thing that’s constant in the world of technology, it’s that it’s “Constantly Evolving.” The same holds true in the realm of Security Systems and CCTV cameras.

Most homeowners and businesses agree that CCTV cameras are a must to ensure the safety of their premises 24 x 7. But, what they can’t seem to agree is, “Whether you should choose an analog CCTV camera system or go digital?”

Eurovigil provides both these security systems to suit the varying requirements of different customers. Today, in this post, we take a closer look at the pros and limitations of each system, helping you make the right decision.

Analog and Digital Security Systems

A Primer: What’s What?

The major difference between these two types of surveillance systems is the method in which video is transmitted.

Analog surveillance cameras send the recorded images using a Co-ax (co-axial cable) to a DVR (Digital Video Recorder). The DVR converts the analog signal to digital, compresses and then stores it on a hard drive. You can then hook up monitors to the DVR to view the videos. Or you can connect the DVR to a router and broadcast the images via internet to your mobile devices.

Digital security systems, on the other hand, use IP-based CCTV systems. They record digital images, which are sent directly to the Network Video Recorder which stores the recording in a hard drive and broadcasts the video through a monitor or via the internet to your mobile devices.

Coming down to the big question, which one should you choose?

There’s no single answer to this. It all depends on several factors like your specific requirements, size of your premises, available space, and geographical location and so on.

To help you make an informed choice, here’s a quick look at the pros and limitations of both.

Analog Security Systems:

Pros:

    • Easy to Operate – DVR is something that’s familiar to all and is quite straightforward to use and operate
    • Lower Bandwidth – Analog videos are often smaller, and since, they use co-ax cables for transmission, instead of a LAN as they don’t require much bandwidth
    • Budget – These systems tend to be priced lower when compared to their digital counterparts

Limitations:

    • Tons of Cabling – Since the cameras need to be connected both to the DVR and the power supply, you’ll have to deal with plenty of wiring in your home or office
    • Image Quality – The videos recorded on analog systems tend to be of low resolution in comparison with digital IP cameras
    • Lack of Encryption – Analog signals cannot be encrypted, making them vulnerable to hackers

Digital Security Systems:

Pros:

    • High-Image Quality – You can record and view images in high definition. Additionally, most cameras come with digital zoom that further adds to the image clarity
    • Lesser Cables – Multiple cameras on the network are connected to a switch, which in turn is connected to the NVR with a single cable
    • Wireless – Digital cameras can easily be connected to a wireless network and don’t have interference like analog systems. You can now watch your live feed from several remote locations
    • Encryption – Digital cameras come with inbuilt encryption, meaning your data is highly secure and safe

Limitations:

    • Higher Bandwidth – With high-definition and high image resolution, IP based systems hog a massive chunk of your bandwidth. But, with cheaper internet costs, this doesn’t pose a major problem
    • Higher Storage – You require higher storage on your hard drive to accommodate the large video files
    • Budget – Initial setup and installation may feel a bit steep. But, since you require only fewer cameras, the costs even out in the end
