How many CCTV cameras do we have?

It is hard for me to see this question and look away. I will try as much as I can to put down meaningful information regarding your question.

CCTV cameras can be classified into:

1. Outdoor Cameras: they are designed to be used outside, they have specific temperature rating. They can’t be affected by rain, sun, dust or any form of humidity.
2. Indoor Cameras: it is designed to be used inside. It will get damaged when used for outdoor application. Most of the indoor cameras are designed to have a vent to allow heat dissipation during operation which is it will be very difficult to use it as outdoor camera.

There are many types of security cameras:

• Bullet camera took its name from the long bullet-like shape

Bullet camera can also be used indoor if you don’t mind the aesthetic.

• Dome camera took its name from the name “dome” which has a round with curve shape.

• Vandal-proof dome/bullet camera is similar to that of normal bullet/dome camera but has a rugged housing which is built to withstand an impact or damage

• IP camera: Unlike analog camera, IP camera uses network protocol to work. They have their own web server. They can also work as standalone device. They can be configured to record to an NVR, FTP site, cloud storage or free third party file storage if done properly.

• Hidden/Covert/Spy cameras are the types of cameras that are concealed in other objects to record you secretly without your consent. They can be found in clock, pen, women bag and etc.

• Turret camera is another version of dome camera with a more advanced infrared LED which is called SMD (Surfaced Mount Device)

• PTZ (Pan, Tilt, Zoom) camera is a camera that can revolve horizontally, vertically and also zoom. PTZ eliminates blind spot which a fixed lens camera wouldn’t capture.

• Speed Dome camera is an advanced PTZ. This camera has a more speed than a normal PTZ. This camera is suitable when you are tracking or tailing a faster object.

• Varifocal camera is a camera that does not use a fixed lens, For instance, if a camera is label as focal length = 3.6mm, that shows that it is a fixed lens and the focal length can’t be adjusted. A varifocal lens allows you to adjust the focal length from the lowest to the highest value. Such cameras allow you to easily zoom on object. Varifocal lens can either be manual or motorized. Varifocal camera has a similar look to other regular fixed lens cameras.

• LPR (License Plate Recognition) cameras are used in traffic to capture license plates of vehicles in motion clear enough for humans and machines to recognize. LPR camera uses advanced technology which eliminates focus problem unlike the regular cameras. LPR cameras mostly come in bullet style.

• Miniature camera is a small square shape camera used where a regular camera can’t fit in. This is also an effective camera with the same features found on the bigger ones.

• Box camera is a type of camera that allows you to choose your own suitable lens, you could choose wide or narrow lens according to your project. Box camera must be placed in a camera housing if it’s going to be used outdoor. You have to buy every parts from box camera, lens, housing, and the wall mount. When buying a camera housing, it is advisable to buy the one with heater and blower. This will help the camera to withstand humidity.

• WiFi cameras are cameras that do not rely on cable connection except for the power which you have to connect the power adapter. They stream video directly to the mobile app, cloud or ftp site if done properly. Some wireless cameras have the option to use a solar panel or even work on a built-in battery.
• Smart cameras are intelligent cameras that respond to request from users. These types of cameras have advance functions more than the normal security camera. Smart cameras can either be wired or wireless.
