Features to look for in CCTV Security Camera Systems
What is CCTV?
Closed-circuit television also known as CCTC is most commonly used for video surveillance. The closed-circuit in CCTV means that a limited number of monitors are available for broadcasts, as opposed to usual TV’s where it is publicly broadcasted at large. Other than video surveillance, CCTV is also used to detect and prevent criminal activities in neighborhoods, both public and private sectors, record traffic infractions etc. It was developed in 1952 to monitor a rocket launch but was later used to test atomic bombs. On top of preventing potential crimes, CCTV cameras have known to be of use to many industries. They can be used by emergency and rescue workers to monitor crisis situations in real time and manage them accordingly. CCTV are also used by traffic lights all over world to record speeding cars and the recordings used as evidence in accidents. Hence, it can be concluded that they have several important uses.
It should be noted that surveillance using any CCTV system can be ineffective when the quality of the video is low, the equipment used is old and system is not installed properly. Hence, it is important to select CCTV cameras and the specific CCTV camera features carefully.
Important CCTV features to consider before purchase and installation
High Definition
High-definition aka HD in CCTV cameras are one of the most important features to consider before installing CCTV security systems. By ensuring that the videos attained from the cameras are of acceptable quality, they can be used for evidence purposes and better preventative security surveillance. 1080p CCTV camera footages are more effective when given to police and prosecutors as evidence to crimes committed. It is able to capture and identify objects and subjects clearly and precisely. Full HD or High definition 1080p HD camera images implies a widescreen aspect ratio of 16:9 and a resolution of 1920x1080.
Night vision and Low-light camera
Starlight IP cameras are a type of night vision and low-light camera that use larger size sensors, wider aperture and reduces the shutter speed enabling them to capture human faces and vehicle plate numbers in extremely low-light. Although it varies from product to product, they can often detect and generate clear images in light as low as 0.005 hux, which is very close to complete darkness. You can choose the quality of the night vision with its lux as its guide, the lower the lux level the better its ability to generate images in darkness or low-light.
Remote access
Remote CCTV access allows authorised personals to access files through a network from a physically distant location. It is a cloud-based network, that allows for constant vigilance and removal of vulnerabilities in the system. It also able to automatically modernise protection with ease, as well as preventing cyber-crime and hacking. With a traditional system, users are often unable to tell troubleshooting issues with the security system until it is too late, and any evidence captured is announced useless. Having a cloud-based network notifies the user proactively when and if the security system has been tempered with or if there are any performance issues. This would ensure that the system is fully functional if any incident does occur.
Motion Sensors
DVR and NVR are ways in which footage are recorded and processed. DVR process the footage in the recorder while NVR processes the footage in the camera and then sends it to the recorder. Motion detecting is most commonly found in DVR’s. The DVR’s monitors the images and concludes when there is movement. At the end of the day DVRs are still machine and often cannot tell the difference between background movement and someone actively trying to break into a property. False triggers can be minimised by limiting the size of the area and the number of areas the screen is overlooking.
Two-way audio
Traditional intercom systems allow for one-way audio. Unlike the more traditional intercom audio systems, two-way audio in CCTV camera security systems allows for users to speak and listen directly using HD video cameras in real time. The microphones, speaker, power source and Wi-Fi connection will be built in. The settings can be catered to the users need using the alarm apps specific to the camera being used and its service provider (CCTV installers Brisbane). The two-way camera allows for user to be more alert about unexpected guests, intruders, shipping and receiving deliveries.
Power source
Other than being wired to electricity, CCTV security systems can be powered by various means. Non-chargeable battery, rechargeable battery and solar energy are some of the options available for use as a CCTV power source. Battery powered CCTV makes sure the walls are not broken to install wires and sockets. It also helps avoid messy cables. Solar powered CCTV cameras on the other hand, not only protects your home but also protects the planet. The power distribution box used also depends on how many CCTV cameras are being installed. Be sure to clarify any doubts before the CCTV supply and installation Brisbane.
