CCTV Camera

When it comes to securing your business, there are many different types of CCTV to choose from. Surveillance plays a huge part in today’s society, and with cameras all around us, our day-to-day lives are experiencing higher levels of security each day.

What many people don’t know, however, is that there are a variety of different types of CCTV camera which suit different situations or premises, and that selecting the proper camera for the right application really is vital.

Different Types of CCTV

Here, we run through these types of camera and what makes them unique and more suitable for some venues over others.

What are the different types of CCTV cameras?

Dome Camera
Bullet Camera
C-mount Camera
Day/Night Camera
PTZ Camera

Dome Camera

The dome camera is one most commonly used for indoor 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 dome cameras include:

Ease of installation
Vandal-proof features
Infrared capability

Bullet Camera

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 protected 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:

Adaptability – can use indoors and outdoors
Compact size aids installation
High quality image resolution

C-mount Camera

Coming with detachable lenses, C-mount cameras allow for simple lense changes to fit different applications. C-mount cameras, where standard CCTV lenses can only cover distances of 35-40ft, can cover distances beyond 40ft thanks to the possibility to use special lenses with these cameras.

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 deterrant)

Day/Night Camera

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 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:

Pan and tilt rotation
Smart tracking features
Powerful zoom and autofocus

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 Satelite @ Internet India Magazine 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.

What to Look for When Buying a CCTV System:

Should my CCTV cameras be discreet or a visual deterrent?
How do I know what to use indoors and outdoors?
What are the light conditions like?
Is image clarity important?
Is audio required?

Should my CCTV cameras be discreet or a visual deterrent?

Box cameras present an obvious sign for anyone who passes by that they are being recorded on CCTV and this can be a great deterrent of theft and crime. Whereas dome cameras are smaller and more discreet. These compact cameras are ideal for monitoring a larger area such as your front or back garden and can follow movement with ease.

How do I know what to use indoors and outdoors?

When thinking where you would like to place your cameras, you might want to think about how they will be mounted and housed, in order to ensure that they’re in the best location and well protected. For example, if your camera is to be placed outside, you will want it to be robust and weather proofed. If it’s to be placed indoors you will want to ensure it will not be affected by grease or steam from a kitchen.

What are the light conditions like?

Test different camera models to see what works best with the lightning in your area, because no matter whether they’re inside or outside, the lighting will differ throughout the day. You will want to check any reflections and backlighting during the day and night.

Is image clarity important?

Depending on how expansive the area is that you want to cover, the resolution of the CCTV camera you choose will need to reflect the landscape in order to provide a clear, useful image. However, if situated in a small room, the camera need not be of a high resolution.

Is audio required?

Audio isn’t required, however, if you do wish to opt for audio there are systems where you can speak to a person who has broken into the property. Audio can be used to deter criminals by automatically playing something when they get a certain point inside, an ideal way to make them think that there are people inside the building.
