Các loại camera quan sát khác nhau
Ở đây, chúng tôi xem xét các loại máy ảnh này và điều gì làm cho chúng trở nên độc đáo và phù hợp hơn với một số địa điểm so với những loại khác.
Dark Fighter Technology Cameras
These cameras can pick up coloured images in very low-light conditions. Dark fighter technology can be used in the day and night and offer optimal performance thanks to its wide range of capabilities. They are equipped with ½” CMOS progressive scan sensors which allows the device to pick up high-quality images and doesn’t require an extra light source – which makes the perfect night time security surveillance camera.
Other benefits of dark fighter technology cameras include:
- Smart features: line crossing, audio and face detection
- Can be used for a multitude of purposes
- High definition
ANPR and LPR cameras are used to read and store data on registration plates. They offer a simple and efficient solution to many organisations including tolling, hotel overstay management and the obvious: car parking. ANRP stands for Automatic Number Plate Recognition (LPR cameras stands for License plate cameras) and these devices help to obtain copious information in a high traffic area to keep any premises secure.
Other benefits of ANPR/LPR cameras include:
- Smart features: information storage
- Can identify cars that have been banned from a premises
- Allows a business to run smoothly
Internal and External Dome Camera
The dome camera is one most commonly used for indoor and outdoor security and surveillance. The shape of the camera makes it difficult for onlookers to tell which way the camera is facing, which is a strong piece of design, deterring criminals by creating an air of uncertainty. Other benefits of this type of camera include:
Other benefits of internal and external dome cameras include:
- Ease of installation
- Vandal-resistant features
- IR night vision
Bullet cameras are long and cylindrical in shape and are ideal for outdoor use. Their strengths lie specifically in applications which require long distance viewing. Installed within protective casings, the cameras are shielded against dust, dirt and other natural elements. The cameras can easily be mounted with a mounting bracket, and come fitted with either fixed or varifocal lenses depending on the requirements of its intended application.
Other benefits of bullet cameras include:
- IR night vision
- Compact size aids installation
- High-quality image resolution
Coming with detachable lenses, C-mount cameras allow for simple lens changes to fit different applications. C-mount cameras can cover distances beyond 40 ft thanks to the possibility to use special lenses with these cameras, whereas standard CCTV lenses can only cover distances of 35-40 ft.
Other benefits of C-mount cameras include:
- Can support changes in technology
- Effective for indoor use
- Bulky size makes them noticeable (which acts as a deterrent)
Capable of operating in both normal and poorly lit environments, these cameras benefit from not requiring inbuilt infrared illuminators as they can capture clear video images in the dark thanks to their extra sensitive imaging chips. For this reason, these cameras are ideal for outdoor surveillance applications in which IR cameras are unable to function optimally.
Other benefits of day/night cameras include:
- Record in both colour and black & white.
- Wide variety of sizes available
- Infrared capability
PTZ Pan Tilt & Zoom Camera
PTZ – Pan/tilt/zoom – cameras allow the camera to be moved left or right (panning), up and down (tilting) and even allow the lens to be zoomed closer or farther. These cameras are used in situations where a live guard or surveillance specialist is there operating the security systems.
Other benefits of PTZ cameras include:
- 200m IR night vision
- X36 optical zoom
- High-quality image resolution
These types of cameras allow for discreet placement which means you can capture good footage of theft and criminal damage. Discreet CCTV cameras beneficial because criminals will be less likely to spot them and therefore, they are less likely to be damaged in the process.
Other benefits of discreet CCTV cameras include:
- Can be propped up or mounted
- Can be disguised in various objects
- Effective for indoor use
Thermal Image Cameras/Infrared Cameras
One of the best 24 hour surveillance cameras around providing airports, seaports, boards and many other critical infrastructures with quality images, no matter what time of day it is. Infrared cameras have small LEDs surrounding the lens to help pick up moving figures in pitch black. Thermal image cameras can see over long distances, up to 300 metres away!
Other benefits of infrared cameras include:
- Detect intruders up 250-300 metres away
- Good in low-light
- Thermal radiation passes through visual barriers
With the ability to zoom in and out without forfeiting its focus. Varifocal cameras allow you to adjust the focal length, the angle and increase or decrease the zoom – ideal for obtaining footage in a square room where you would normally experience a ‘dead zone’ with any alternative, fixed lense camera.
Other benefits of varifocal cameras include:
- Can capture those ‘dead zones’ that other cameras can’t
- Offer exceptional focus
- Work well up close and at long distances
These cameras share the images across the internet, so CCTV footage can be easily accessed. Network cameras are ideal for both domestic and commercial purposes because you can see what’s going on whilst away from the property.
Other benefits of network cameras include:
- Data can be easily accessed
- Ideal for homes and companies
- Less cabling and less maintenance
High Definition Cameras
High definition cameras have such a high resolution that they’re mainly used in high risk establishments such as banks and casinos. This is to capture a good image of anyone who enters and exits to maintain high security and maximum safety. These cameras are great for spotting misconduct and allows the user to zoom in for extra clarity, should the footage need to be used in court.
Other benefits of high definition cameras include:
- Clear, detailed pictures
- Offer maximum safety for high risk establishments
- Can zoom in without losing focus
What Type of CCTV Camera Should I Buy?
It’s extremely important to ensure that you have chosen the right CCTV camera, because depending on where they’re positioned and their primary use, you will need to find one that best accommodates your needs.
Whether you’re looking to install a CCTV camera outside a property to catch criminal activity, or have placed one inside to monitor the home or a company’s goods, there’s something for everyone.
3 factors you need to consider:
If you’ve been asking yourself, ‘what type of cctv camera should I buy?’ then you have come to the right place, because the experts here at Caught on Camera will be covering things to consider and the best types of CCTV cameras for the home. But first, there are 3 factors to consider:
1. The correct lense
This will ensure that you receive a quality image. Choosing the right lens will allow your camera to focus and will bring enough light to the sensor on the camera, helping you to read registration plates and recognise faces etc.
Having more detail will, of course, help in all situations, because it means that you will be able to see exactly what’s happening and get a clear record on film. A zoom lense can provide customers with more information because optical zoom can adjust the light as it reaches the sensor, enabling flexibility and enhanced pictures.
2. The correct sensor
There are two things to take note of when finding the right sensor: the type and size. These are:
- CMOS (complementary metal oxide semiconductor)
- CCD (charged coupled device) cameras
CCD are more expensive than CMOS and they produce a clearer image, ideal for identifying faces and registration plates.
3. The correct output resolution
The more pixels, the better the picture. The highest resolution you can get is 700TVL but many mainstream cameras range between 300-550TVL. It’s important to match a resolution that your camera can produce, anything more is completely unnecessary.
