The Most Popular Types Of Security Cameras

When it comes to security camera systems, you must first learn what each has to offer. Many security companies offer digital and analog systems, various types of device models, where cameras and recorders have many different functions, so it takes a lot of time to understand what each function is responsible for, what to pay attention to and what equipment will best suit your needs. Below we will try to explain all the functions and briefly describe what’s important to look at when you’re choosing the right security camera system for your home or business.

What are the types of video surveillance?

Video surveillance, or CCTV (Closed Circuit TeleVision), is a surveillance system that allows you to observe and record images from a distance, using cameras. Currently, there are three types of monitoring systems on the market – analog, hybrid and digital (commonly known as IP).

The analog system is the oldest representative of closed-circuit television. It allows you to preview only within the local network built on coaxial cables, individually connecting cameras with the recorder. The image is recorded in PAL/NTSC resolutions – with a maximum resolution of 768×576 pixels, so its quality is not too high.

Hybrid systems are based on hybrid recorders or IP video servers, which enable the connection of analog cameras with digital IP equipment while obtaining the functionality of the IP devices. Hybrid devices convert analog signals to digital and enable its digital recording or allow for remote viewing.

IP vs CCTV: What’s the Best surveillance camera Choice for your business or home

IP monitoring is the most modern type of video surveillance, which uses the Internet Protocol (IP), which allows to obtain high resolution video images (up to 4K).  IP monitoring offers advanced possibilities, such as image analytics, recording on a memory card (SD), or easy system expansion. In IP monitoring systems, it is possible to connect specialized IP cameras to the IP recorder via ethernet cable to a broadband modem or router or via a WiFi router. IP monitoring will find its application in single-family houses as well as commercial and industrial buildings.

There are many advantages of the IP system in comparison to the analog and hybrid CCTV systems. First of all, there is no need to connect each camera directly to the recorder, thanks to which IP monitoring is very flexible and enables the dispersion of devices operating within the network used – this solution enables simple and quick expansion of the system.

Secondly, the image quality recorded by megapixel cameras, which is limited only by the size of the matrix and sensor, is much higher. IP cameras with HD (1.0 Mpx – 1280×720) or Full HD (2.0 Mpx– 1920×1080) resolutions are already a standard. For more demanding customers, cameras with resolutions above 3.0 Mpx are available, enabling very high quality recording, which can be used, for example, for observing warehouse facilities.

What are the most popular types of CCTV cameras?

  1. Color and day/night CCTV cameras

IP-vs-CCTV-cameras-business-or-home-chicagoCurrently, only color CCTV cameras are available, which provide a much better distinction between people and objects than previously used monochrome cameras. A color image provides much more information that distinguishes individual objects from each other. However, color cameras require much better lighting conditions due to their lower sensitivity. The PAL system is most often used in color cameras to transmit the video signal. These cameras have two video outputs and require two cables to transmit signals. One wire transmits the luminance (black and white signal) and the other chrominance (color signal).

In recent years, day/night CCTV cameras have become very popular in video monitoring systems. Such cameras combine the advantages of monochrome and color cameras. With good lighting, they provide a color image with all its advantages. In low light, where the color cameras could no longer work properly, they switch to monochrome.

  1. DOME CCTV cameras

Dome cameras are named after their hemispherical shape. They are most often intended for indoor applications, e.g. office buildings, malls, supermarkets. Their shape and compact size give them w low-profile. The user can see the camera, but is not able to clearly determine the direction of image recording. Dome cameras are mounted under the ceiling, which makes them vandal-proof. Vandal-proof cameras are designed for places where vandalism is the main problem (prisons, warehouses, car parks). They can be equipped with an infrared illuminator for crisp black and white pictures in total darkness.

BULLET type CCTV cameras have a cylindrical shape and are most often intended for outdoor use and are highly weather-resistant. They can be also used indoors, e.g. in underground car parks. Bullet cameras are usually mounted on the walls, near the ceiling, and in the corners. They are often equipped with IR LED lighting, which can provide illumination when there is no other light source.

A bullet camera monitors one area and its monitoring field remains constant during operation.

  1. PTZ cameras (Pan-Tilt-Zoom camera)

PTZ cameras can rotate in horizontal (left-right, panning) and vertical (up-down, tilting) planes and zoom in and out. Thanks to this function, they are used in places where there is a need for high accuracy and precision, and in places with high traffic. They are also great for tracking objects, e.g. during sports events. One PTZ camera can replace several fixed cameras. The movement of the camera is controlled by software or can be controlled manually – the user can freely change the position of the camera and use the optical zoom to view a specific fragment of the monitored scene. The price of PTZ cameras is higher than the price of cameras without the rotation function.

7 Essential Home Security Tips You Need To Know

Over the years, security systems have improved a lot, and systems that are offered by present-day security companies are more sophisticated than ever. From digital security systems to smart home systems that can be remotely controlled via your smartphone, many modern security systems are now automated and can be controlled via an app or your phone. This gives you access to many features and essential information about your home’s security with just a click of a button. However, if you want to go a little further and learn about other steps that you can take to improve your home’s security in addition to having a professional home security system installed, or if you live in a rented house or cannot afford security camera systems, we have gathered a list of 7 practical home security tips that you can use today.

  1. Don’t leave valuable items visible

The most important advice we can give is: Do not make your house an available target. This simply means – try not to let potential burglars know that you have valuables in your home. So if own an expensive car, keep it in the garage. If you have valuable electronic equipment or furniture, you may want to consider keeping the windows closed at night. Don’t make yourself become the easiest target.

  1. Forget about “hiding a key”

Card-Access-Reader-Union-AlarmA hid-a-key may seem like a clever idea in theory, but not in practice. Hiding a spare key is the easiest way to let criminals into your house. The problem with this concept is that the spare key is usually hidden in an easy-access place that’s easy to remember. Instead, consider installing Card Access Systems or a smart door lock that you can unlock with a unique user code. You can share this code with your family members and closest friends to give them access to your home without risking a thief finding your replacement key.


  1. Don’t make it obvious that you’re not at home

If you are ever going for a long vacation, ask your neighbors to pick up your mail, mow your lawn, and do other things that keep your house from looking like nobody’s home. Burglars often observe a neighborhood for a longer period of time and they might even notice that your car is parked in the same spot. However, if you are not willing to ask your neighbors for help, consider leaving some lamps lit in the house to give the impression that someone is home and ask the post office to save your mail so you don’t have to worry about it accumulating in your mailbox.

  1. Invest in motion-activated lights

Happy homeowners certainly know how many accessories you need to buy to properly take care of your home and its safety. If we do not want to be surprised by burglars who like single-family houses, apart from the best LED lighting, invest in motion sensors that will work when an unauthorized person enters the property. They’re a great way to keep burglars and criminals out of your home and allow for easier identification if caught in the act.

  1. Secure your second floor

Although the doors and windows on your first floor may be protected and ready to withstand any security and safety threats, we often forget about the security of our second-floor entry points. Security cameras with motion-activated recording, balcony security gates, heavy window locks and security grills may also be essential to prevent burglars from entering your home through a balcony or a second-floor window. The most important thing is to remember to close all your windows when you go to sleep or leave a light on while you go away for a few days.

  1. Ask your local police to do a house inspection

If you’re not sure if you’re on top of things when it comes to your home’s safety, contact your local police department to schedule a simple home inspection. It usually takes about 15-20 minutes and the police officers will be happy to share their knowledge with you on personal protection and home safety.

  1. Window security

When securing windows, you should not focus only on installing a lock on the handle side, but also on the equally less resistant side – the hinges. Window locks that are currently available on the market are extremely effective in protecting against burglary. Another thing you might consider installing are anti-burglary blinds and rollers that will work perfectly on the basement and ground-floor windows and will provide an adequate security level to ensure effective protection against thieves and other criminals.

IP Cameras: What They Are and How To Use Them

Chicago Security Expert is just that, premier security companies in Chicago, that offers all security and wiring solutions. All in one place. We are committed to providing comprehensive technological answers integrated to suit the unique requirements of our commercial and residential clients.

An IP camera, sometimes referred to as an Internet Protocol camera or Webcam, is very much like a computerized camcorder, which transmits and receives information over a network. It has its own IP address that only needs a connection to any WiFi network to transmit video footage, unlike a standard webcam found on a computer, that transmits data from the host computer’s IP address. However, an IP Camera’s main functionality is no different than any other digital camera or camcorder; it works by capturing video footage of whatever it’s pointed at and then transferring that footage to a hard drive or a live broadcast to a mobile device.


The IP camera is no different than a smartphone or PC when it comes to hooking it up to an internet connection. You can either use a wireless WiFi connection or a hardwired ethernet connection to get your camera(s) online and running. Once connected, the cameras can be properly configured to any kind of network you plan on connecting them to. Once configured and connected, you point the camera at whatever you wish to receive video footage from and feel secure knowing you’ve got a robotic eye watching your business or home around the clock. As a final security measure, be sure to set up passwords for your cameras in case of a hack or security breach, so that nobody has unauthorized access to your cameras and footage.



As the security camera market expands, IP cameras are becoming a more affordable security option than ever. One major benefit of IP cameras is the ability for your security footage to be streamed to any smartphone, laptop, tablet, or PC through an internet connection. With some brands, those same devices can even remotely control the camera to pan or zoom as desired. And as far as different brands go, there are many cameras that vary for indoor or outdoor use, and come in a variety of discrete and obvious shapes and sizes. With an IP Camera, bid farewell to the bulky computer terminals and low-quality video footage that comes with CCTV cameras.

IP vs CCTV Surveillance Security Cameras Installation in Chicago

IP vs CCTV: What’s the Best surveillance cameras choice for your business or home?

When choosing the right security camera system for your business, your two options are either CCTV (Close-Circuit Television) or IP (Internet Protocol) cameras. In functional terms, both systems use a camera to transmit a video signal to another storage or viewing device in real-time. However, that is where the similarities end and it becomes a matter of choice. Hopefully this article will help you make sure that your choice is the right one.

What’s the Difference?

As mentioned before, both systems have a different way of transmitting a video feed. CCTV cameras transmit their footage by changing the video signal into a signal that can be picked up by a standard TV, hence the name Closed-Circuit Television. On the other hand, an IP camera acts like its own computer and wireless sends the video data to the storage or viewing device the same way you would watch a YouTube video.

Video Quality

Designation H x V
CIF 352 x 240
2CIF 704 x 240
4CIF 704 x 480
D1 720 x 480
720p HDTV 1280 x 720
1.3MP 1280 x 1024
2MP 1600 x 1200
1080p HDTV 1920 x 1080
3MP 2048 x 1536
5MP 2592 x 1944

General Overview

Both systems come with their benefits and shortcomings, and these few bullet points will do a quick rundown of both systems’ pros and cons before going into greater detail.

Let’s start with CCTV:


  • More vendors and installers available
  • CCTV systems are rather simple to install
  • Cheaper than IP in many cases


  • Lower frame rate and image quality
  • Smaller field of view
  • More cables

Moving on to IP:


  • Higher image quality and field of view
  • Remote viewing and controlling
  • Less wiring and no bulky terminals


  • Greater initial cost
  • HD video footage needs more storage space
  • Learning curve with interfaces and configuration


For the longest time, CCTV systems were the cheapest form of video surveillance and they still hold that title for the most part, especially in regards to initially purchasing your system. However, these costs don’t stay low when you account for all the necessary video and power cables for each camera you decide to purchase. IP cameras on the other hand, while some higher end model cameras are more expensive than CCTV, many IP cameras are reaching the price range that’s very similar (albeit a bit more pricey) than CCTV systems. And because each IP camera can transmit video data individually, there is no need for video cables, saving you money and time. And a final note, IP systems tend to last longer than CCTV systems if you’re willing to put in the extra money; you get what you pay for.


When it comes to features, it seems as though IP cameras pack a greater punch than CCTV systems. To begin, an IP camera’s resolution is much greater than the average CCTV camera, being able to have a field of view that’s six times larger. A greater field of view means that fewer cameras are needed to cover the same area, further reducing setup costs. Because IP cameras are connected through WiFi, the owner is able to not only view a live playback of the footage, but also digitally zoom in to catch important details like facial features or license plates in case of an incident.


Finally, the most important aspect to video surveillance: storing the videos. CCTV systems store their footage on a DVR just like any home TV, which can limit the number of cameras you can own before needing to purchase another DVR. On the contrary, an IP system stores its footage as digital files, meaning that a more compact hard drive can hold more footage than a DVR. And if more storage is needed, hard drives are easy and cost-effective to expand, especially with the decreasing costs of hard drives and digital storage.

In Conclusion…

IP surveillance cameras systems are truly the best way to go. The versatility gained from them outweighs their greater setup costs and also outweighs the advantages of a CCTV system. In all honesty, an IP system should be purchased only if it is the very first surveillance system you are installing or if you want an upgrade. Otherwise, if the CCTV ain’t broke, no need to fix it.
