Security cameras, known as CCTV, are used to prevent crime before it happens and alert authorities during the crime itself. CCTV cameras can be placed anywhere, as long as they’re close enough to a power source. These cameras are very useful in areas with a lot of criminal activities because knowing that there is a chance of the crime being recorded prevents some of the criminals from even attempting to commit one in the first place. digital video recorders can be installed in your office or home and they can be placed in a spot that is visible to others, or you can hide the cameras and observe what is going on from a distance. Modern video recorders are equipped with high-quality audio and video systems, meaning that you can use these cameras for more than just recording crimes – you can listen to people and monitor their behavior as well. It’s certainly no wonder that this type of camera is becoming more and more common in office spaces.
On the other hand, surveillance cameras are useful for detecting and recording any activities, but in order for action to be taken immediately, they require constant monitoring. Those cameras are usually set in public places, such as malls or crossroads. The good thing about surveillance cameras is that you can use your phone or computer to monitor all activities they capture via the Internet. These cameras are known also as IP cameras and require a constant Internet connection. The signal is transferred over the IP network, which is where the cameras got their name from – as well as why they require a constant stable internet connection.
Each of these cameras has its own pros and cons. Depending on the purpose of camera installation, the price you wish to pay, and the location you want to place your cameras, you can make your choice between surveillance and security camera.
What is a security DVR camera?
As previously mentioned, there are two types of cameras – surveillance and security cameras. Unlike traditional analog surveillance cameras, digital video recorder – DVR cameras are based on digital technology – DVR stands for Digital Video Recording. Every recording made with a camera of this type can be stored digitally which allows for higher quality and visual fidelity of the video and requires lower maintenance.
All of the security cameras require a central video recorder to transmit and store digital footage. DVR is actually an improved version of VCR because it is using a hard drive instead of a videotape for saving all the content.
The camera needs to be connected to the power source in order to function.
Now we come to the question of storage space. You might be wondering just how many hard disk drives you need in order to save all your surveillance footage. This really depends on the number of channels you decide to have. You can choose between 4, 8, and 16 recording channels. And obviously, the more channels you have, the more storage space you will need. We will just give you an example – a hard disk with the capacity of 1TB will have your footage stored for 19 days with 4 channels, 10 days with 8 channels, and 8 days if you choose to have 16 channels.
How to choose between 4, 8, and 16 channels for DVR cameras?
Well, this one is pretty simple to explain. Each security camera requires its own cable that needs to be plugged into its own port on the DVR camera. And each port corresponds to a certain channel. This means that 4, 8, or 16 channels are actually representing 4, 8, or 16 security cameras connected to their own ports.
Now, how do you choose between those numbers of channels? First of all, the number of channels depends on the number of cameras you have and the ports you decided to connect. And this, in turn, mostly depends on the area of coverage. A house or a smaller business will most likely be just fine with 4 or 8 channels. However, if the space you’re planning to cover is a bit larger, you’ll want to opt for using 16 channels. And if you’re planning to cover a truly large area and even having 16 channels is not enough, you can always switch to NVR cameras – as they’ll allow you to have 32 channels at your disposal.
The crucial thing you need to do here is to try and predict how many cameras you will need, based on the size of the area you want to cover. Having a 16-channel device would not be a bad choice, since you do not need to have all 16 cameras connected instantly. This way, you can use a smaller number of cameras to secure your business, and if you plan to expand said business at a later point, you will have an available option to add more cameras at any given moment without having to buy a new device.
NVR vs DVR – pros and cons
Let’s first explain what NVR is. Just like DVR was presented as a newer version of VCR, NVR is an advancement of DVR technology. NVR stands for Network Video Recording. The cameras are taking footage directly from the network they operate on. In order to use an NVR system, you absolutely need to have IP cameras. These cameras require the use of an Ethernet cable or a WiFi connection to function.
So, what is better? NVR or DVR cameras?
The thing both of these camera types have in common is the fact that they record footage. The difference between them manifests in the way they accomplish this task.
DVR cameras are using analog cameras to record footage via coaxial cable and then the record processes the footage. As stated above, NVR cameras have the ability to process the captured footage live thanks to an Ethernet cable or WiFi connection.
After the video is processed, both of the cameras work the same – you can access the footage from your mobile phone or a PC.
DVR surveillance system – pros & cons
When it comes to the DVR system, it’s cheaper than NVR since it’s using less complex technology which has a lower cost of production. Also, you don’t need to be tech-savvy in order to use a DVR system. And the quality of the captured video can improve if you use HD instead of a coaxial cable. It’s also worth noting that DVR usually needs to be close to the camera in order to encode the video signal.
On the side of cons, the quality of the footage is lower than it would be when using an NVR system because the technology is older. Also, there are extra cables and installations required, since these cameras cannot be simply connected to WiFi in regular circumstances. Another noteworthy thing to remember is that this type of camera is good for observing, but cannot record audio – so keep this in mind if recording sound is something you also require.
NVR surveillance system – pros & cons
Unlike the DVR system, NVR cameras are recording both video and audio at the same time. Images are of higher quality, and fewer cables are required for setup since these cameras can be connected to WiFi. Other than that, when using NVR, the video signal is encoded directly in the camera, allowing for a bigger distance between the NVR and the camera.
On the other side, the NVR system is more expensive than the DVR and harder to operate with.
Depending on your needs, you can choose the type of surveillance camera you need. This answers the question should you buy CCTV (DVR) or IP (NVR) cameras.
Will any security camera work with any DVR?
Here we come to the matter of camera compatibility. This is important, as not every video recorder can work with every camera. DVRs require analog cameras, while NVRs require IP cameras. However, the story does not end here. Sometimes, some recorders also require cameras from a certain manufacturer.
Also, you need to choose the right security camera recorders resolution. digital video recorders cameras are usually offering “D1” resolution, better known as standard resolution – 720×480.
Another thing to think about; DVR cameras are encoding the video signal in the DVR, not at the camera, meaning that the distance between DVR and a camera is a limiting factor. When choosing the right camera for you, make sure to take the distance range into consideration.
If you are not sure whether or not your DVR will be compatible with certain cameras, you can ask the manufacturer directly. If this is not an option for you, the next best choice would be to let professionals install your surveillance system, since they already know what they need for a successful installation without compatibility issues.
When it comes to HVRs (Hybrid Video Recorders), they can be connected to any analog or IP camera and help you make the transition from DVR to NVR easier.

What is the cost of a DVR security system?
In the end, we come to the question that many ask. How much will you have to pay in order to get a DVR security system installed? The cost of the DVR system itself ranges from $50-$500 per camera. If you decide to buy a very advanced camera, the price can go up to $1,000 per camera. The recorder itself also comes with a price. If you decide to go with Swann DVR, the average price is $200. Besides this, there are also costs of the security system installations. Unless you decide to set the system up yourself, expect to pay the same amount you paid for your system for the installation as well. In the end, you might also have monthly fees for monitoring and storage, if you decide to outsource these workflows. Thankfully, these costs are not too big, usually coming in at $30-$50 per subscription.
