Using surveillance cameras at worksites is becoming more critical as the unexpected seems to increase at a moment's notice.
Capturing footage of theft or fire on a camera will make a difference in faster evacuations and offer visual proof if crimes occur. Types of cameras available, though, are sometimes technologically complex.
Those investing for the first time can sometimes become confused about what constitutes CCTV cameras and one using IP. If you’re looking for a reliable home alarm system, then look no further! Security Systems has you covered.
It comes down to one type connecting digitally to the Internet and the other being analogue. Understanding these differences (and some similarities) will help you make a better decision if leasing your surveillance cameras for a work site.
Understanding The Difference Between The Most Popular Security Camera Options
Whether you're looking to monitor employees in a store setting, service providers in your home, or any potentially suspicious behaviour on your property, there is a security camera type best suited to your needs.
The most popular types of security cameras on the market include CCTV cameras and IP cameras, which function differently to meet users' specific security needs.
Hidden cameras, which can often work with either CCTV or IP-based systems, can act as a solution to some of the problems that come with having visible security measures in place at your home or business.
When it comes to choosing the best security camera type for your monitoring needs, there are several considerations you can make: cost, convenience, video clarity, remote monitoring, and more.
In this piece, we'll explore the pros and cons of different security camera systems so you're able to make an informed decision on how .to protect your home or business best
What Are CCTV Cameras?
Any CCTV camera is essentially analogue, meaning not hooked up to a network. Despite being "non-digital", it doesn't suggest digital technology isn't involved. It only applies to the camera itself.
When hooking the camera up to a DVR, digital technology comes into play. As a result, one can see the differences between IP and CCTV cameras aren't necessarily quite as wide as one would think.
Setup is also relatively simple, except it involves one peripheral: A DVR. Doing this will require a cable connection, potentially making installation more complex.
Once the camera captures the footage, it's sent to the DVR, becoming a digital recording.
HD analogue is now a reality since the DVR will convert the footage into digital, giving more reason for CCTV to stay relevant. Even so, what other aspects between IP and CCTV exist as a clincher in making a final buying/leasing decision?
CCTV cameras are most often used in business or government settings or for monitoring large areas such as retail stores, banks, and other institutions.
They are often seen surveilling various public areas in cities, such as parks and highways. In addition, law enforcement professionals often use them to monitor general behaviour, traffic patterns, and more to help secure public safety.
A system in which all elements – from the cameras to the recording devices – are directly connected to keep the video from being broadcast over public airwaves and on a closed circuit (hence the name).
Since its development in 1942, CCTV has undergone drastic changes. Whereas once upon a time, the technology could only be used to observe live footage, it quickly developed into a recording system that allowed users to both view and preserve data.
This made it the ultimate security technology. Today, property owners everywhere utilise CCTV technology to build simple to comprehensive security camera systems for their safety and peace of mind.
What Are IP Cameras?
An IP Camera (Internet Protocol) sends and receives data via a computer network and the Internet (hence its name).
These types of cameras are typically used for surveillance monitoring. They are either "centralised" (meaning they require a central network video recorder to handle the recording, video and alarm management) or "decentralised" (meaning no NVR is necessary, and the footage can be recorded and managed from any local or remote storage media).
Though a webcam is essentially an internet-based camera, "IP" is typically reserved for surveillance equipment.
Videos are stored digitally using a network video recorder, or NVR, rather than a physical DVR.
Additionally, IP cameras are easy to install and have flexible expansion capabilities in connecting additional cameras, other systems, and storage applications.
IP cameras can be used in conjunction with CCTV systems to cover blind spots or have cameras less likely to be seen and discovered.
Choosing an IP camera is becoming a top priority in an age where most want better picture clarity in their security cameras. According to recent statistics, IP cameras will exceed 100 million units sold by 2025.
Picture clarity is more important in a security camera, even if there could be some disadvantages to using a digital camera. It all depends on your individual needs at the site.
Since IP cameras are wired up to the internet 24/7, more security measures are put into place to protect from online threats. Still, with costs now at more reasonable levels for IP cams, more companies invest in them.
Also, the installation has become more accessible thanks to wireless technology, plus being simpler to use since no other equipment is involved.
This still doesn't mean analogue won't have some advantages for those wanting something more straightforward.
IP cameras can be used in a variety of settings, from business to personal. In addition, because many IP cameras are wireless, placement can be much more flexible, offering you versatility in your security.
IP cameras offer remote viewing options, making them perfect for situations where you want to monitor what's happening even when you're away.
What Are IP Cameras Used For?
IP cameras are most commonly found in commercial and industrial settings. Still, due to their cost-effectiveness and ease of use, they are becoming more popular for home security systems.
Thanks to advanced technology and the diminished need for more and bulkier equipment, internet protocol cameras can be as small as a few inches long and are great for monitoring small and large spaces alike, including everywhere from safes to private offices and retail stores floors to parking lots.
They can be placed beside a computer, on a windowsill or even inside a teddy bear (think—nanny cam). The uses for this type of equipment are virtually endless.
IP Cameras: An Advancement In Technology
IP Cameras are the most significant technological advancement since cameras have been produced.
There are two types of video surveillance systems, CCTV (closed-circuit television), analogue, and IP cameras, also known as network cameras.
Both CCTV systems and IP systems transmit video to the desired destination. In addition, CCTV systems convert the video signal to a format used by televisions, VCR's, or DVR's.
IP cameras convert the video signal into IP packets to be transmitted over the data network or Internet to a network storage device such as a server, NAS, or by storing onboard the camera.
The IP system has the added benefit of using the network devices, which can expand the range of the IP cameras beyond that of a CCTV system.
CCTV Vs IP Cameras
When comparing CCTV vs IP camera systems, both have advantages and disadvantages. CCTV systems, in the past, have had a lower initial price point when compared to IP systems.
However, that is rapidly changing as IP cameras, and storage devices have shown a continued decline in pricing.
Many studies show that the total cost of ownership of a CCTV system is higher when compared to the life of the system.
One of the factors helping to reduce the cost of an IP system is the cost of cabling. For example, CCTV uses coax and a power cable, while an IP camera uses standard network (Cat 5e or Cat 6) cabling.
Using a POE switch or injector, an IP camera can be powered and transmit video over a single cable, reducing the cabling cost compared to CCTV.
Another IP camera advantage is that the capabilities of IP far surpass that of an analogue system. For example, IP cameras today have a much higher resolution than CCTV cameras.
The higher resolution of IP cameras results in a much larger field of view when compared to analogue cameras. This means you can reduce the number of cameras required to view a specific area by using IP cameras, reducing the total ownership cost.
It can take as many as six analogue cameras to view the same area as one 2 megapixel IP camera.
Digital zoom is another feature of an IP camera system that is not available in most CCTV systems.
Digital zoom gives the user the ability to "digitally" zoom in to live and recorded videos to see the image in more detail.
This allows for improved investigative research upon viewing recorded video after an incident. The more pixels you have in an image, the more you can zoom in before the image begins to break up.
This is especially useful when trying to read a license plate or recognise a person.
Expansion of a CCTV system can be costly due to the typical limitation of a DVR in a CCTV system. Most DVR's are restricted to 4, 8, 16, or 32 cameras and to expand beyond that requires purchasing another DVR.
With an IP video system, a user can add additional storage to what was originally purchased.
This allows for the expansion of the system without a significant purchase. In addition, the cost for hard drives has decreased over the last few years, making storage a minimal cost when reviewing the cost of the entire system.
IP cameras have an onboard processor that gives them more capabilities than an analogue camera.
Features such as motion detection, cross-line detection, wide dynamic range, and improved low light functionality allow the camera to make adjustments and trigger events within the camera itself, thereby allowing the video server to function more efficiently, improving overall performance.
Another factor in determining the right system for your business is to review the goals of installing a video surveillance system.
How the system will be used is an essential part of choosing items such as:
- Correct Cameras
- Storage Needs
- Camera Locations
Errors in any of these items can provide you with a system that doesn't meet the objectives required. Check out Security Systems’ range of high-end security access control systems installation for your home or office protection needs.
A Comparison Of CCTV And IP Cameras
There are some significant differences between CCTV systems and IP cameras.
Although IP cameras are the modern choice, many business owners and property managers prefer to use CCTV cameras to monitor large spaces.
Below is a comparison of some of the main features of each system.
- Sends video back to a base station or DVR (digital video recorder) via coax or UTP cabling
- Video is recorded on a physical DVR which can be connected to the Internet for remote viewing capabilities.
- Power and network cables run between each camera and the base station.
- Because cabling is required, CCTV cameras all have to be in one location.
- Cameras typically offer a lower resolution of 960 x 480, but some systems offer HD resolution.
- Primarily provides video surveillance without advanced features.
- There is a physical limit to the number of cameras that can be added to the network, usually fewer than 12
- 2-way audio for communication with people on the other end
- Uses television broadcast signals
- Broadcasts video as a digital stream over an IP network to an NVR (network video recorder) where videos are stored digitally rather than physically
- Often have SD cards, allowing them to record locally or send video via the Internet to an NVR.
- It uses PoE (Power over Ethernet), making it unnecessary to run power cables.
- Because cabling is not always required, IP cameras do not need to be kept in one location.
- Some cameras feature an increased resolution of 4096 x 2160. The standard answer tends to be 1080p HD.
- Includes advanced features such as analytics, advanced motion detection, and remote focus
- Can add nearly unlimited cameras to the network
- 2-way audio for communication with people on the other end
- Uses WiFi and bandwidth
The Cost Aspects May Differ
To keep in mind, CCTV camera systems might double in cost due to a required DVR purchase. In turn, CCTV cameras can sometimes cost more than the recent price drops of IP cameras.
Much of this depends on purchasing cameras for a worksite as part of capital spend. With leasing an option, the pricing is more equal since you're only renting the cameras for a short time.
Determining these costs goes by where you buy or lease your cameras and how many other features you need. Worksites are going to differ in what kind of security they may require.
Thanks to CCTV cameras giving one the ability to go back and review prior footage without an internet connection, the extra price for CCTV might be worth it.
Frame Rate And Motion Blur
Another factor in a final decision is the frame rate of the camera. HD analogue has certainly improved frame rates, yet only go so far. On the other hand, IP goes to the 4K level, including superior ability to capture the action.
In a scenario where your worksite needs to capture more movement, a camera with a higher frame rate may need to move to the priority list. The reason being that motion blur would occur on anything lesser.
Playing back footage could prove detrimental if a camera can't pick up a clear image of someone running or stealing an object.
Reviewing that in a courtroom during a case could come down to a conviction or a culprit going free due to unconvincing camera footage. Adding to this, IP cameras frequently give more comprehensive views for a more wide angle.
IP Camera Advantages Outweigh CCTV Camera Advantages
IP video surveillance is quickly becoming the standard for video surveillance. With advanced features, scalability, and a declining total cost of ownership, IP versus CCTV is no longer a difficult decision.
A benefit of going with the IP camera option is always being connected to the Internet for digital security. Part of this includes using updated encryption systems to ensure no one will hack into the camera.
CCTV cameras definitely won't have encryption available, making them slightly more vulnerable to hacking attempts. Perhaps this is rarer with a CCTV system, though it can happen.
Whether it's someone trying to exact revenge, or just wanting to create random chaos, hacking into your security cameras could become a big problem in how secure your worksite is.
If anything valuable is around, this might allow thieves to move in and take things after a hacking attempt.
Proper encryption is always necessary nowadays for cybersecurity. An IP camera is open to any internet vulnerability, but the latest encryption technology will always stop someone in their tracks.
A Few Other Things To Consider Between IP And CCTV Cameras
A significant technological advantage of IP cameras is their sensors, usually covering more expansive areas. On the other hand, CCTV cameras are a little more limited in the space they cover.
Because of this, you may need more CCTV cameras to cover a particular worksite, where one IP camera could cover the same space.
Yet another thing to think about is the intelligence and analytics IP cameras can provide as well. These can become valuable if you need to prepare reports on how many incidents might occur on your worksite.
All of this does require a more significant learning curve, however. You may not need that if used to using CCTV cameras in the past.
No matter your choice, leasing your cameras will always become a better option since investing may exceed your budget range. Let Security Systems get you peace of mind by installing top-quality and reliable home security cameras in Melbourne.
In addition, your needs may change from worksite to worksite. In one place, CCTV cameras may suffice, where another site may benefit from IP cameras.
