What comes to your mind when I question you about your home and family? I’m sure one of the things would be safety, as it is a priority for all of us.

As it said,‘’ It is better to prepare and prevent than to repair and repent’’.

Considering this, what steps can we take to prioritize safety?

A home surveillance DVR system is the most economical method of protecting your house or place of business. These gadgets can capture hours of video using superior-quality cameras, putting you at ease and peace. Finding an excellent security camera DVR on a budget has become simpler due to technological advancements and more competition.

Based on their features, usability, capabilities, and durability, we selected the best HD DVR systems. Let us dive more into the security systems for a better understanding.

What Is A DVR Security System?

You can save the video whenever you wish to see surveillance footage from your CCTV camera. A DVR system will make sure you have security footage as evidence in the event of an emergency or crime.

In fact, companies of all sizes ought to develop the practice of consistently backing up their data because it protects you in the event of theft or loss. They should alert you if storage is getting low and offer simple backup options so you can store your footage elsewhere.

Difference Between DVR vs. NVR

Both NVR and DVRs are fundamentally used for video recording. A digital video recorder is called a DVR, whereas a network video recorder is called an NVR. At the recorder, DVR systems evaluate the video data.

In contrast, NVR systems do the video data processing and encoding at the camera before streaming it to the NVR recorder for storing and remote viewing. In the case of DVR, the signal stability is much higher, whereas the signal stability is lower and less stable in NVR.

DVRs and NVRs need different kinds of cameras since they process video data in various manners. While most DVRs are used with analog cameras, NVRs are typically utilized with IP, or protocol-based, cameras. It’s vital to remember that NVR systems can be wired or wireless, in contrast to DVR systems, wired security systems.

Benefits Of DVR Security System 

Easy installation: Compared to analog systems, digital systems are easier to install, need less equipment, and can help your security team operate the surveillance system more efficiently.

Cost-effective: A digital system can function with less physical infrastructure. You’ll also need lesser sensors to cover the same area because digital cameras provide images of higher quality and with wider viewing angles.

High-quality graphics: These digital systems capture events so clearly that you can also give law enforcement high-quality photographs to assist in prosecuting suspects in case of theft.

As we have come this far, let us check out the top models of DVR systems to implement in your lives.

Before rushing in head first and buying a whole system, consider your budget and ongoing operations before deciding.

Take the time to consider all aspects, risks, and opportunities before investing heavily. Selecting the ideal video recorder system for your security requirements requires careful investigation.

Buying CCTV Security Camera Systems

Here at CCTV Security Pros, we’ve been providing Surevision security cameras and systems to Fortune 500 companies, universities, government agencies, and residential homes at more than 70,000 locations across the United States since 2008.

If you’re looking for where to buy the best CCTV security cameras and recording systems, how to power security cameras, and how to install wired security cameras, you’re in the right place.

Security Camera System Video Quality

HD Video is Superior. There’s no contest between HD video and older analog technology. HD video is much higher resolution and displays far better clarity. This is critical to see details like faces and license plates. You can expect our HD CCTV security camera systems to be at least 3-5 times sharper than standard analog cameras.

Standard Definition

240p – 480p Resolution
< 1 megapixels

High Definition – HD

720p – 1080p Resolution
1-2 megapixels

2K High Definition

1440p Resolution
4 megapixels

4K Ultra HD

2160p Resolution
8 megapixels

Understanding Megapixels

Pixels are the individual blocks of color on a digital screen and a megapixel is one million pixels. 1-megapixel cameras can capture video at 720p resolution. 2-megapixel cameras capture video at 1080p, also called high-definition. A 4K Ultra HD CCTV security system requires 8-megapixel cameras.

The higher the resolution and megapixel count, the sharper the image. One great benefit of higher-definition cameras is that you can digitally zoom or ‘blow up’ an HD picture, and the integrity of the image will remain better intact rather than appearing pixelated or blurry like the older analog CCTV security cameras.


There are 2 types of HD CCTV security camera technologies; HD-over-Coax systems and internet protocol (IP) systems. A recorder that supports HD over coaxial cable is called a digital video recorder (DVR). IP cameras connect to a network video recorder (NVR) using an Ethernet cable. At CCTV Security Pros, both DVR and NVR units provide the same essential functionality. Either can be used to view live or recorded video and also to view your cameras remotely on a smartphone, tablet, or computer.

One of the main differences between these CCTV security types is the type of cable used to connect the recorder and cameras of the CCTV security systems. Only HD over Coax recorders are backward compatible with older analog cameras. In other words, you can buy HD security cameras or use any existing analog cameras with our HD over Coax digital video recorders.

IP-Based (NVR) Systems

IP camera systems are the new industry standard. Our Network Video Recorders can display images and video up to 4K Ultra HD. IP cameras are connected with CAT5, CAT5e, or CAT6 Ethernet cables. All of our IP cameras are PoE (Power over Ethernet) meaning that both power and video are transmitted over a single cable. Standard IP cameras can be run up to 325ft. Our CCTV security hardware includes repeaters and switches for customers who require further cabling. Some of our systems include “extended” PoE meaning that they can transmit both power and video over 800ft using a pure copper ethernet cable.

Installation with a single PoE Ethernet cable makes IP-based NVR surveillance camera systems exceptionally simple to install. You won’t have to hassle about running a power cable to each individual camera. An Ethernet connection back to the NVR is all it takes to get them up and running.

HD-Over-Coax (DVR) Systems

HD-over-Coax CCTV security cameras are connected using traditional coax cable with BNC video connectors. Our Digital Video Recorders are compatible with new 4K Ultra HD video as well as older analog cameras. The most common type of cable used is RG59 Siamese cable. The term Siamese means there are 2 cables (power and video) running side by side that can be pulled apart. This is important because HD over Coax cameras are not powered from the recorder. Rather, HD over Coax cameras can be powered using an individual power adapter or multiple output power when running multiple cameras.

HD-over-Coax CCTV security systems are extremely beneficial in locations with existing analog infrastructure in place. You can use the same older cable when buying new HD cameras and recorders. Another benefit of HD over Coax is that video can be transmitted well over a 1000ft distance.

NDAA Compliance

Many CCTV security systems are banned for government use. These banned products include components from named Chinese manufacturers listed in the 2019 National Defense Authorization Act (NDAA). Our full line-up of SureVision™ (Green-line) professional-grade products are all NDAA compliant and suitable for government use.

Cameras of all Styles

We carry many different styles of cameras in sets of complete CCTV security systems. A lot of people like bullet-style cameras due to their sleek housing. Other people prefer dome-style cameras for their discreet, low profile, and vandal-resistant design. A large majority of the cameras we offer are fully weatherproof for indoor or outdoor use.

The style of the camera is independent of the technology it’s made with. Qualities and features like the resolution, zoom, and night vision can be just as good whether you prefer bullet-style or dome-style cameras. Buy security cameras for discreet surveillance, or cameras that stand out from their environment to maximize their deterrence factor.

Wide Angle Advantages

The size of the camera lens will determine its viewing angle. Our widest lens size is 2.8mm and will produce a 110-degree super wide angle which is good for covering the entire immediate perimeter. A popular 3.6mm lens will display a 90-degree wide angle.

Customers like wide-angle CCTV security cameras because they offer the most “bang for the buck”. However, if you need to focus on an object that is much further away then you will require a more powerful lens such as 8mm, 12mm, or even a 50mm or 100mm lens for a good close-up video of objects that are over 100ft or even 200ft away. Many of these cameras offer a varifocal lens that you can adjust to achieve the perfect angle. Better yet, many of the varifocal cameras have a motorized lens so you can simply adjust the angle directly from your recorder or remote device.

Compromising for an Optimal Image

There is always going to be a compromise between the width of the angle and the distance you can see. The perfect solution may sometimes be a combination of wide-angle and varifocal cameras. You can place each at different points on your property to create a comprehensive CCTV security camera system. You can buy security cameras separately, or as part of a complete CCTV security system bundle.

Wireless Camera Systems

Wireless IP camera systems have also become popular with the release of the many consumer WiFi gadgets available today. These cameras are often limited in terms of selection, clarity, reliability, and function. It is important to understand that the term wireless mainly applies to video transmission. Many of these consumer devices are battery-powered. We do not offer battery-powered cameras because they need to be recharged, making them less reliable. If you operate a business, it’s much better to buy a professional CCTV security system.

Powering Wireless Cameras

Some wireless cameras require separate power although it may be somewhat uncommon for a power outlet to be located in the same location where the camera will be mounted. Another consideration is that wireless cameras can be subject to interference or loss of WiFi signal. We recommend hardwired cameras for applications with further distances or structures that may prohibit an adequate WiFi signal.

Motion-detection Recording

Many customers who buy our CCTV security system cameras set them to record only when motion is detected to save hard drive space. You can even get fever detection with the right tools. For example, a 4-camera HD recorder with a 1TB hard drive can record continuous video at 4mp for up to 7 days. If the same recorder is set only to record on motion or on a schedule, the storage time will increase very significantly. Some lesser expensive recorders only have space for a single hard drive. Many of the units we carry have multiple hard drive bays to accommodate more video storage if and when required.

Storing Video Footage

Another consideration when designing a video monitoring solution is storage. Most customers want to store their captured video footage for 7-10 days. All of our video recorders have internal hard drives inside the units where the CCTV security video is stored. We only use surveillance-grade hard drives for the best durability. The higher-resolution cameras will require more storage simply because they consume more data. This is why we offer customers the ability to increase the size of their hard drives to meet their exact storage needs.

If you came to learn how to get the best CCTV surveillance cameras, how to install your wired security cameras, or how to power an outdoor security camera system, we hope this is the info to get started.

What to do if the IP camera is not seen by the DVR

Often, users encounter difficulties when connecting IP cameras to the DVR – this is due to the peculiarities and differences in the configuration of the device protocols.
Users who buy equipment on Chinese sites most often find themselves in a situation where the components of the surveillance system do not fit together.

There are problems when connecting IP cameras from manufacturers. In order to try to connect an IP camera, it is necessary to carry out the following methods listed below, and often it is possible to connect an IP camera to the DVR. But there are exceptions – when it will be impossible to connect this camera to this particular NVR model.

To connect to a DVR or NVR, it is important to know the IP address of the device of the connected camera; additional data will be required to enter the device: login and password, which can be viewed in the instructions that come with the surveillance camera. If the password is not known, then in this case it remains to try to guess passwords from those used by manufacturers, in this way it is not difficult to guess the default password and login set by manufacturers of IP surveillance cameras.

You also need to know the ONVIF protocol ports, usually 80.
To implement a connection via RTSP port 554 (there are exceptions), you also need to know the correct form of the URL of the link, which also indicates the username and password, the stream stream for the main and second stream by permission.

To connect an IP camera using the ONVIF protocol, it is important that the DVR and the IP camera are on the same subnet – for example, the IP address of the DVR is 192.168.[ 1 ] .103 ; The IP address of the camera is 192.168.[ 1 ] .23

If you try to connect the camera on different subnets, the connection to the DVR will fail, for example, the IP address of the camera in another subnet will be 192.168. 2 .23
You also need to pay attention that there is a certain range below which the DVR will not be able to connect to the camera, for example, 192. 168. 224 .103 and above this value.

Enable auto search for the IP address of the camera on the DVR – this mode is now available on all modern DVR NVRs, if the camera is detected, then in this case the probability that the IP camera will be connected to the DVR increases. When an IP address is found, add the found camera to the device list to the desired channel. After that, you need to try to pick up passwords – if the login passwords are not known, or enter the login password login values; port 80 and try to connect to the camera.

If you failed to connect via ONVIF protocol, install an application to search for cameras that support ONVIF protocol ONVIF Device Manager. Using this search program, collect all the received data and try again to connect the IP camera to the DVR. ONVIF Device Manager will also show the URL of the IP camera link, which you may also need in the future if you have to make a connection via the RTSP protocol.

In cases where the camera does not support ONVIF, you must use other programs to find devices on the network. Our technical advice is this free network scanning app

Download and install the Avigilon Camera Installation Tool – despite its name, this software perfectly searches the network for IP cameras of any manufacturer.

RTSP and camera connection method via RTSP protocol.

If you cannot connect the camera to the NVR, there is this method. In some DVR NVR models, it is possible to connect IP cameras via the RTSP STREAM protocol. To do this, open the RTSP settings on your DVR and enter the RTSP broadcast URL details. The correct form of the URL link specifically for the camera used can be viewed in the instructions or contact the developer. If there is no data for entering the RTSP URL, then you can select the data type of the link, which consists of the following values.

But there are differences, so the type of link can be of a different type, for example
rtsp://admin:123456@192. 168.1.23:554/profile0

rtsp:// for main video stream
rtsp:// for the substream.

URL link type is decoded as follows:
1. Protocol type rtsp://
2. Login and login password: admin:123456
3. Camera IP address: @
4 Port: 554
5. Stream /stream1

Viewing the RTSP URL image is also possible through the free VLC player and other applications that support RTSP video streaming. link

When choosing a camera today, the user must understand that in addition to matching the camera with the DVR, it is necessary to understand that at this time obsolete components and devices of video surveillance systems are being replaced, including this primarily concerns the surveillance cameras themselves. Today, the latest breakthrough photosensitive platform CMOS BSI and already CMOS BSI-2 of repentance are being introduced. Users who are not familiar with BSI technologies are doomed to buy outdated cameras with image sensors that are blind by today’s standards.
