How a CCTV Camera Can Help in Crime Management
CCTV cameras are a useful tool in crime management. They act as a deterrent and also help in post-crime investigations.
From hardwired cameras that broadcast to a central system to IP security camera systems that can connect to the internet for anytime, anywhere footage viewing. From night vision and infra red cameras to weather resistant bullet cameras.
Video Resolution
One of the most important aspects of a security camera is its image resolution. Resolution refers to how many pixels are in the recorded image, and higher resolutions produce solar powered outdoor camera sharper images with more detail. Resolution is also important when it comes to identifying people and vehicles, as well as distinguishing colors.
CCTV resolution is typically listed in TV lines, with higher numbers indicating greater resolution. Many legacy systems only have a 420 line resolution, making them less than ideal for high quality surveillance applications. However, even a 720p resolution can provide a good image for most applications. The key is to balance budget, zoom capability, and other factors when deciding on the right resolution standard for your application.
The most common resolutions are CIF, PAL, and HD. HD (1280 x 720, or 720p) provides a high quality image with excellent clarity for identifying people and vehicles. This resolution is also commonly used by video monitoring companies when streaming live cameras over the internet.
Another aspect to consider is the frame rate. The frame rate refers to how many images are captured per second, and a higher number means smoother motion when analyzing footage. The downside of a high frame rate is that it can increase the size of video files, which can impact storage and bandwidth requirements.
Lens
A camera’s lens is key to ensuring a high quality image. CCTV cameras with a larger lens are often used in areas that need to capture a greater field of view such as roads or logistics industries. These cameras can also have a zoom function allowing you to see closer.
Smaller lenses are often used for more discrete security purposes. These cameras can be placed in a smaller housing so criminals will be less likely to spot them and damage them. These cameras can also have a zoom feature, enabling you to get close ups of items such as licence plates or faces.
Network CCTV cameras are also an option and work by streaming footage across the internet, meaning that you can access them from a remote location. This can be useful for businesses that want to monitor their premises whilst they are away from the site. These cameras can also be equipped with a digital zoom which allows you to zoom in on live or recorded footage and still maintain clarity. The amount of pixels in an image determines how cctv camera far you can zoom before the image starts to break up. This is particularly important if you need to read a number plate or recognise someone.
Motion Detection
When it comes to keeping your property secure, CCTV systems can help in many different ways. They can deter break-ins and vandalism by scaring criminals with the prospect of getting caught on camera. They can also provide a record of what happened so that police can catch the perpetrators. In addition, CCTV can be used to monitor traffic and keep a watchful eye on employees.
A CCTV system works by clicking multiple images in a continuous sequence and then transmitting them to a recording device (DVR or NVR). The recordings can be viewed on a TV monitor or remotely on a computer or smartphone. Depending on the setup, some cameras may also be connected to an intruder alarm so that if the alarm is triggered it can send a signal to the professional alarm receiving centre (ARC) to visually confirm the event and even share the footage with the local authorities.
However, if you are capturing footage outside your boundaries and public footpaths, then you will need to comply with data protection laws and register as a data controller. This means you will have to provide justifiable reasons for your actions and protect the rights of any people captured in your footage.
Night Vision
Using extra sensitive imaging chips, these cameras can operate in pitch black conditions without needing an inbuilt infrared light. This makes them ideal for properties that need 24/7 security monitoring such as factories and banks. They can also pick up coloured images in low light conditions so are able to function in a range of environments.
These cameras allow for complete control of the image being recorded – you can move the camera left and right at the touch of a button or zoom in or out as needed. They are often used on larger properties with a guard that is there to monitor the CCTV system and ensure the correct actions are taken.
The footage is either stored on a hard drive or SD card within the camera, or can be relayed to smart devices such as mobile phones in real time for immediate action. It can then be viewed in a variety of ways from a TV, a PC monitor or even remotely on your computer using an internet connection.
Whether you’re looking to deter burglars or vandalism, monitor your shop or warehouse or check on the safety of your children and employees, State Systems can design and install a range of CCTV systems for both indoor and outdoor use. From a single wired CCTV camera to keep an eye on your front door, to a full network of IP cameras and sensors to keep an eye on your business premises and staff, we can tailor a package that’s perfect for you.
