Should I Fix Bullet Camera or Dome Camera or Turret Camera or  PTZ Camera or a Combination of All Together-

Before you decide about which camera to fix , you should know these terms and cameras in details .When we are talking about Bullet , Dome, Turret and PTZ Cameras  ,we are talking about the security cameras types based on the shape . A CCTV Camera ( or Security Camera) is a part of the CCTV  system and it is responsibe for taking video or still footage and send that feed to the a central location for store, view or further processing  by a digital device . These CCTV  Cameras can be classified into various types depending upon various measures . i.e. on the type of wire they run on, on the type of signals they send to central unit , on the type of connectivity they need ( wired or wireless ) or on the type of shape they comes into .

There are few shapes in which security cameras comes and  in that Dome , Bullet and  Turret shape is more common with a totally different shape of PTZ cameras  . Because of their different shapes , one type of camera may perform better in some aspect and vice versa .

Dome Security Cameras 

Dome Cameras are named for their dome-like shape. The Dome camera is one of the most popular choices around, the most common type of camera that you are likely to see in modern installations and the reason behind this is the dome cameras are non-intrusive and  more fashionable and blend in very well with their surroundings. If the area that you are installing your camera is susceptible to vandalism or tampering, you should consider installing a vandal dome camera. Dome cameras may come into mono-focal and vari-focal lens options and user can have flexibility to adjust the focal distance of the camera to exactly where it is needed. Again, when choosing the camera, you should think of where to fix it and hence choose the right dome camera among Indoor Dome, Outdoor Dome or Vandal Proof Dome cameras.

Pros:

  • Dome cameras are non-intrusive and merge well with the indoor interiors.
  • Smaller form factor .
  • Because of their dome shape, it is difficult for someone to tell which direction the lens of a Dome Camera is actually aiming.
  • Dome cameras are preferred choice for home interiors as they  are more fashionable and blend in very well with their

Cons:

  • These cameras are Prone to IR bounce as the lens and IR LEDs are covered by a glass .
  • When mounting outdoor in vertical position , water droplets which falls on the glass , and gets collected  , blur the lens .

Mostly Used at :Dome cameras are commonly used in surveillance systems inside of homes, casinos, retail stores, and restaurants , hotel common areas and offices .

Mounting Options:

Mounting Options: A dome camera is usually mounted on the ceiling, under the eaves or the soffit, indoors and outdoors.(  For better aesthetic , use PVC junction boxes which comes in square  and round shape . It can be mounted  on a vertical wall or any pole etc , using PVC or metal clamp.

 

 

Bullet  Security Cameras 

Bullet Cameras, as the name implies are of the shape of a rifle bullet ( Cylindrical & Long ) and can come in fixed or house vari-focal lenses . The thinner and smaller bullet cameras are often called Lipstick cameras , again,  due to similarity in shape to a lipstick.  Owing to its shape and size, these cameras can house large zoom capabilities and extended IR.

Pros

  • Due to its shape it can house high zoom capabilities.
  • Extended IR
  • These are highly visible and hence ideal for deterrent .
  •  Bullet Cameras are easy to install than Dome or PTZ cameras .

Cons:

  • You can not adjust the viewing angle once installation is done  .
  • Unsightly in residential installations.
  • Largest form factor and  more intrusive .
  • Restricted View Angles due to body.
  • Prone to wildlife nesting.

Mostly Used at :  For Outdoor Locations ,locations where you need surveillance and deterrent both , for commercial establishments .

Mounting Options :On a wall vertically , on ceiling using ceiling mount bracket , on a pole or any structure using appropriate bracket , it needed .

Turret Cameras 

Turret cameras  are also know by many other names of mini dome , eyeball or flat-faced dome cameras . In this type of camera the Lens and IR LEDs come into the inner part which looks like a sliced sphere and  this part is fixed  into an outer part and can swivel around in it . This type of design is called as ball and socket (  or ball in socket ) design .

Turret cameras has some advantage over dome and bullet cameras and the major among those are when fixing ourdoor a turret cameras don’t  have issue of the IR reflection like in dome cameras ( due to their outer glass housing ) and it does not attract spider web like in bullet cameras .

There are two type of Turret Cameras in the market depending upon the type of IR it is using. Some turret cameras comes with the common setting of the number of tiny IR LEDs around the camera lens as in case of dome or bullet cameras , where some comes with advance EXIR ( Extended IR ) , which is a single IR glass ( rectangular or rectangular ) on the side of the lens. EXIR Cameras gives more efficient night vision  and longer distance of IR coverage.

Please Note:A turret camera and a dome camera looks almost similar but there is a simple way to identify which one is which , in case the IR LEDs and Lens of the camera are behind  the glass , it is bullet camera and if not , then it is dome camera .

Pros:

  • There is no IR  Reflection .
  • Turret Cameras can be mounted vertical or horizontal.
  • Longer and Better IR Capability.

Cons:

  • Less vandal proof than dome.
  • Slightly larger form factor vs dome cameras.
  • Bit costlier than dome & bullet cameras .

Mostly used at : At all the indoor places in home , office , retail , schools  etc .

Mounting Options : The mounting option for Turret Cameras are same as of  Dome Cameras .

 

PTZ  Cameras 

PTZ Cameras have the ability to move up, down, right, left, and even zoom. These are more common for bigger outdoor locations  or warehouses etc and can manage a very large area single-handily. These camera has many benefits over normal Dome , Bullet & Turret Cameras and are more advanced , but more costlier  . PTZ cameras comes with Auto-Tracking , Guided Tour and Manual Control Mode  , which give it edge in managing a large area .

Control

The PTZ cameras can be controlled manually for their PAN , Tilt and Zoom functions using the on-screen buttons or UI of DVR , Camera Management Software , Web Interface or Mobile App . Also , you can use a Joystick for the same .

These cameras can also be set up on a Guard Tours in which the camera will monitor the area by moving repeatedly at a pre-scheduled speed and angle .

 

Pros:

  • Greater field of View , as they can see full 360 degree .
  • Built –in motion tracking
  • Manually Controlling Cameras
  • A powerful zoom
  • Vandal Resistant –Their installation location makes them vandal resistant as in most of the cases they are mounted high on a pole and not easily in reach .
  • Simplified Installation : With PTZ cameras there is not need of taking field  and angle of view into consideration and hence the job of installer is quite easy .
  • Monitoring Large Area Per Camera : A single PTZ camera can do the work of many dome or bullet cameras .

Cons:

Cost -The first drawback of the  PTZ cameras are that they are very costly ( many time to a bullet or dome with same megapixel ) and for a normal security surveillance of residential complex , it may not worth investing this much of money .

Temporary Blind Spots or Limited View at a Time : This is one of the major downside of PTZ cameras as they single handily monitoring  a large area over 360 Degree and they can not record an incident where the camera is not specifically looking at . For example, if we are controlling the camera manually and moved a camera to view some location and an incident happens at some other location , it can not record that . It is very good that they can be Pan Tilt and Zoomed , but they can not see everywhere at a time .

Mostly used at :

  • Parking Lots/Garages
  • Rooftops
  • Construction sites
  • Warehouses and more

Mounting Options : There are many type of PTZ cameras in the market and  they should be mounted differently as per in their user manual . Table mounted PTZ cameras , should be kept or stick to the table or any flat surface from where it can have unhindered view of the full area . Bigger PTZ cameras mostly comes with the special mounts and can be fixed below ceiling , side of the wall , on a pole etc .

 

Conclusion: 

Lets go back to our main question of deciding which camera to use in our video surveillance system , and our view in that is –

  • For the Indoor area everywhere -Turret Cameras . ( It will be bit costlier than dome , but worth it )
  • For Open Outdoor Areas – Bullet Cameras
  • For Covered Outdoor Area with Tempering Risk – Vandal Proof Dome  Cameras
  • The PTZ Cameras are a special case which is mostly used in the commercial applications i.e. Public Spaces , Parking Lots , Recreation and Parks , Open area of Institutes ,Farms, Ports  etc . If you have a bigger compound and don’t mind investing that much of money , you can go for it , but make sure this should not be the only monitoring camera for that area and it should work in conjunction with fixed cameras which are monitoring the full area.
