How Commercial CCTV Security Cameras Work

Post Written by Neil Jones

No matter the business, when security is a top priority, CCTV security cameras are a robust solution to monitor business premises and prevent crime. 

But not every CCTV security camera is built in the same way. Depending on your needs and challenges, SmartWatch Solutions offers tailored systems to provide maximum security bespoke to your situation. 

 

Technical features of CCTV security cameras 

Here is a list of CCTV features and add-ons available with our security systems, along with their functionality and benefits. 

Night vision & thermal cameras

When CCTV is intended to monitor an area day and night, it must be equipped with infrared technology (otherwise known as night vision). 

Businesses that operate outside of standard hours, like warehouses, construction and industrial operations, would benefit from night vision capabilities to maintain round-the-clock security without the expense of lighting infrastructure. 

Infrared LEDs activate in low-light conditions and can capture clear black and white footage 30-50 meters in complete darkness. Our CCTV have smart switching modes that automatically change from day and night modes based on light levels for seamless 24/7 surveillance. 

Similarly, for areas with limited visibility, such as complete darkness or fog, thermal imaging cameras can detect heat. These cameras are ideally used for perimeter security and early fire detection. 

Can you use both night vision & thermal cameras?

Many commercial CCTV security cameras can integrate both technologies, and some combine both into a single unit, automatically switching between modes based on conditions like light, weather, temperature and additional security triggers like fire or burglar alarms. 

Motion detection 

Using infrared sensors, security cameras can detect heat movement and differentiate between human, animal and environmental activity. 

Motion detection is beneficial for large-scale operations and can reduce security staffing costs as it automatically alerts to genuine threats while filtering out false alarms. 

It can set specific areas for monitoring while excluding busy zones to reduce false alarms and focus on more critical areas. The technology can also send instant alerts to security personnel or business owners via apps or email.

How do you prevent false alarms from motion detection CCTV?

As mentioned, our technology is intelligent and can distinguish between relevant threats and environmental factors. For added protection, you can set customisable detection zones, adjust sensitivity levels and use AI-powered recognition to differentiate between humans, vehicles and animals. 

Audio recordings 

Depending on the nature of a business, audio and video surveillance may be required, particularly in commercial settings, for insurance and legal benefits. If security cameras are equipped with audio recording, to remain compliant, they must be explicitly stated in signage throughout the monitored areas. 

Audio recording systems utilise directional microphones with noise-cancelling capabilities to filter out background noise like wind, traffic or machinery. It also amplifies human speech within a 10-15 meter range for intelligible recordings. 

CCTV monitoring benefits from audio capture to provide additional context to visual footage for incident investigation and evidence gathering. 

Is audio recording legal in the UK?

Yes, it is legal, but it requires strict regulations. You cannot record private conversations without consent, but capturing audio in public areas of your business premises is permitted, provided it is properly disclosed and justified for security purposes. 

4K vs HD 

The quality of your CCTV system camera is essential for all businesses. It can be the difference between identifying a criminal and not. 

4K cameras provide more pixels than HD ones, which means clearer identification of faces, license plates and fine crucial details for evidence. They also have incredible zoom capabilities, even when digitally zoomed, which would pixelate HD footage. 

However, HD cameras can still be beneficial for well-lit areas, and they require less storage and bandwidth costs, which can be more beneficial. 

Is 4K worth the extra cost over HD cameras? 

They are definitely worth the investment if you have the budget. While they require more storage, the superior image quality can be crucial for evidence in legal proceedings. 

But if you’re looking for more general monitoring where fine details aren’t critical, HD cameras offer excellent value. 

Time-lapse add-ons

All of our CCTV security cameras can be equipped with our time-lapse feature, which captures HD images at regular intervals and compiles them into a single video, providing a visual way to monitor progress and identify project issues early. 

Time-lapse cameras are best suited for construction companies, project managers and businesses that require progress documentation for client reporting, dispute resolution or operational analysis. 

Its long-term pattern analysis helps identify security vulnerabilities, traffic patterns and operational inefficiencies. 

How much storage space does time-lapse recording need?

Time-lapse cameras require up to 90% less storage than continuous recording, allowing you to monitor progress over extended periods without overwhelming storage costs. 

CCTV security camera installation

There are various features and add-ons available for CCTV and security cameras, and each business benefits from different choices. 

At SmartWatch Solutions, all our security cameras are set up to be completely bespoke to your needs, with flexibility to add on features like night vision for added security, or even time-lapse components.
