One of the toughest business decisions companies need to make is when selecting a new video surveillance system, as it’s a rigorous process to compare camera offerings and technologies, and to evaluate price structures.
With its proven performance over the last several years, IP surveillance systems have become the defacto standard for most professionals. Those experts typically cite the numerous benefits that IP cameras offer, including higher image resolution, ease of installation, scalability, and analytics as rationale – which are all valid. However, the biggest drawback is the high price tag when considering making the switch from an analogue to a dedicated IP surveillance system.
In reality, many end users don’t need networked IP cameras in every location throughout their facility, as the additional features and benefits IP cameras typically provide may not be necessary in every location. Ultimately, the decision to stick with analogue or move to IP needs to be based on your surveillance objectives and future needs.
Advantages of 4K
Consider this – you’re managing an analogue surveillance system and your primary goal is to increase image resolution; 4K analogue cameras may be your ideal solution. Advanced 4K analogue surveillance cameras deliver a myriad of advantages, including:
- Superior resolution
- Lower cost and easy installation.
- Picture clarity even under changing or difficult lighting conditions
Models with 2 and 4 megapixel resolution, such as Dahua’s HDCVI 4K cameras with scalable HD-over-coax technology, provide security professionals with greater situational awareness and are available in multiple form factors to provide exceptional quality video & audio for a wide range of surveillance applications.Since 4K analogue cameras are not connected to an IP network, they do not present the cybersecurity risks that are typically associated with IP cameras
Greater distance, greater definition
Another benefit of 4K analogue cameras is that their higher number of pixels provides increased digital zoom performance without pixilation versus traditional HD or 2K cameras. This allows security operators to see further into the distance with greater definition. The added resolution is especially important for popular applications that require higher levels of detail, such as face and licence plate recognition or object analysis, as well as emerging video analytics and artificial intelligence applications for future system enhancements.
4K analogue applications
4K analogue cameras are also ideally suited to cover large fields of view such as in sports stadiums or airports with great detail and accurate colour reproduction. Their superior digital zoom capabilities can allow 4K analogue cameras to do the work of two cameras – one for a wide view and another for close-up – without sacrificing quality or compromising security. This can also help dramatically reduce hardware and installation cost, and simplify video monitoring.
Finally, since 4K analogue cameras are not connected to an IP network, they do not present the cybersecurity risks that are typically associated with IP cameras. With the ever-increasing amount of sensitive and personal information stored on networked drives at businesses of all types, the value of removing one more potential network entry point cannot be understated.
Overall, with 4K analogue cameras, security professionals can take advantage of higher resolution video on an existing, cost-effective platform that’s safe from network intruders with isolated and limited installation downtime and exceptional cost-efficiencies.
