Closed-Circuit Television (CCVTV) camera types and their specifications show that these are surveillance systems that are best suited for different applications. Some have been built to be disguisable, while others are large enough to deter an intruder. Similarly, there are CCTV cameras that are specially designed for indoor usage while others are more suited for outdoor applications.
On the other hand, CCTV cameras have signals that are not transmitted publicly for security purposes. These units need to be strategically placed and their feed observed from a monitor. CCTVs gain the name closed-circuits because their cameras communicate with the monitor or video recorders using wireless communication links. Now here’s a review of the different CCTV cameras and their specifications.
1. C-Mount Camera
C-Mount CCTV cameras have a lens that is detachable to suit a wide range of applications. These units can capture images that are at a distance of over 40 feet. As such, instead of using a regular CCTV that covers around 35 to 40 feet, it can be replaced with a C-Mount camera. Also, these cameras can be zoomed in without losing focus or great image detail.
C-Mount cameras are large in size which makes them easy to be spotted. The advantage is that it can deter an intruder from breaking into your premises since they’ll be aware that they’re being watched. What’s more, these units are suitable for use indoors and support changes in technology.
2. Bullet Camera
Bullet cameras can be likened to an oversized ammo cartridge due to their long cylindrical design. These are outdoor camera systems that may sometimes be used indoors, where extended viewing up to 40 ft is required. Bullet cameras often have a fixed length which gives them an angle of view up to 80° horizontally and 40° vertically. These cameras may have a fixed lens of 2.5 or a varifocal lens of 3 inches long.
Interestingly, the protective casings shielding these cameras makes them withstand harsh weather conditions. They can be used in hot and cold locations and the temperature won’t impact their recording capability significantly. The same can be said about dust, dirt and other natural elements affecting their functionality. Much more, the unit won’t break down easily.
3. Dome Camera:
Dome CCTV cameras have a dome cover which helps to hide the camera and make it difficult to tell which side they are facing. The unit itself may be large and visible to the eyes, but an intruder is unable to tell where the camera is pointing at. Dome cameras are indoor security systems and they are mostly used in retail stores and offices. These cameras may feature infrared illuminators to allow them to capture videos even in low light conditions.
On the other hand, the dome camera has a fixed viewing angle such as 100° which is evident in bullet cameras. It is possible for these cameras to get destroyed easily due to the plastic material that covers it. Nonetheless, some are made of strong material that is resistant to impacts and harsh weather conditions.
4. Pan Tilt Zoom (PTZ) Camera:
Pan Tilt Zoom (PTZ) camera answers to its name by allowing its users to pan, tilt, and zoom, the camera. Each of these is highly beneficial to see images more accurately. All you have to do is manually control them to offer the desired functionality you require. Move them from side to side, zoom the lens closer or farther, and move them up & down to get a better look at your subject and the environment.
PTZ cameras are used in highly sensitive zones that have to be under surveillance all the time. Further, these units have a 200m IR night vision, X36 optical zoom, and they produce high-quality images thanks to their high resolution.
5. Wireless CCTV Camera:
These are wireless CCTV cameras that do not need wiring to transmit footage from the camera to the TV monitor. Thus, they can be installed easily. The live feed of these cameras can be streamed wirelessly and for this reason, they can be watched from a smartphone or computer. It, therefore, ensures that homeowners or business owners are informed of what is going on in their premises even while away.
6. Day/Night CCTV Camera:
Day/night CCTV camera offers high performance in both normal and poorly lit environments. Also, they do not have built-in infrared illuminators, yet they can still capture quality images even in lowly lit places. The latter is a result of the sensitive imaging chips they feature.
Over and above that, these CCTV cameras are used in outdoor locations, and they can still function properly under direct sunlight or glare. Furthermore, they have a wide dynamic range which enables them to capture images even from a distance. Day/night CCTV camera can also produce black and white images as well as colored images.
7. High Definition (HD) CCTV Camera
HD CCTV cameras capture images and videos of high quality. This is because their resolution is often higher than other CCTV cameras. A higher resolution ensures that images are clear, bright, and rich in color. These images still retain their high quality even after being zoomed a number of times.
These are the basic types of CCTV cameras with their specifications. While they all offer the ability to record images and videos in real-time, some do it better than others. Also, they are best suited for their different applications whether indoors or outdoors.
