What You Need to Know When Buying A CCTV System

In Hong Kong, many of us are used to seeing things happen on CCTVs. Particularly a robbery, theft, or accident, CCTVs become some of the most useful forms of documentation of evidence. CCTV videos are so popular that there are even YouTube channels catered to CCTV viewers. Closed Circuit Television cameras, as they are called, offer to complete the package of home, office, or outdoor security. When people know that they are being watched, there is a lower chance of delinquent behaviour. So what do you do? You can increase security with minimal effort by installing a CCTV.

Why You Need A HK CCTV Camera

Still wondering why you need a CCTV? It’s simple – CCTVs tend to ward off delinquent behaviour thanks to an effect called the Hawthorne Effect. The Hawthorne Effect, otherwise known as the Observer Effect, happens when a person is aware that he or she is being monitored. The individual will change his or her behaviour to suit the person who is watching them. In the case of CCTVs, often, a person will be deterred from doing wrong if a camera is present in the vicinity.

Fun fact: The Hawthorne Effect can also be seen when taking photos. Most people will strike a pose as soon as the camera is facing them.

Here are some additional reasons as to why you might consider setting up a CCTV system in Hong Kong:

  • Documentation – to record any misdemeanour or crime in the vicinity
  • Record-keeping – to keep track of date and time (especially when travelling)
  • Time-lapse – to view progress over a day/month/year

Now that you are convinced to get a CCTV camera system, let’s look at some steps on how to choose the right CCTV.

How to choose a CCTV camera?

Determine what it is you are trying to monitor. Monitoring indoor would require a different system as compared to outdoor. How large is the space you are filming? Larger areas may need to use zooming capabilities. You can also get CCTV's with built-in memory cards.

  • Do your cameras need to be hidden or not? If you’re trying to catch a known thief, you might want to use an inconspicuous one.
  • How many cameras do you need? To monitor a few areas at a time, you might need a few cameras strategically set in place.
  • What basic features you are looking for in a CCTV. Some CCTVs points to consider are colour and definition of the image, connection and storage of the data, motion detection, night vision and weather protection.

These are just some steps to consider when choosing a CCTV camera system.

How many days can CCTV record?

Many organisations now require that CCTV video images are recorded and archived continuously from all cameras for 90 days and more. In large systems, this can create a significant storage requirement. This is compounded by users wanting to store video at the highest quality and maximum frame rate, particularly where CCTV footage is required for evidential purposes.
