Monitor Resolution of your Security Camera Recorder

Set the Monitor Resolution of your Security Camera Recorder

It’s very crucial to review the entire CCTV footage via monitor. If you are having issues with using a monitor or TV to view your security camera system it usually relates to the resolution that the system is trying to display. It's important to take the necessary troubleshooting steps to gather information on why the display is not working. Often times it's easy to assume that the port is no longer working though it can be remedied by double checking settings. If you know the recorder is receiving power and you can see lights in front of it, but you don't see the menu screen or camera grid on your monitor connected to it, then you most likely have an incorrect display resolution set that is not compatible with your monitor or TV. Remember, you need to “see” what camera “saw”. 

If you have an older or inexpensive computer monitor or TV, chances are that it may not support all the different resolution outputs available on our security DVRs and NVR. Selecting a resolution unsupported by your monitor may leave you locked out of your video recorder unless you either connect it to a 21.5" or larger computer monitor from a reputable manufacturer like Acer or Asus. Depending on the model of your NVR, you can also adjust the resolution of the Display using your web browser. The latter allows setting the Display output resolution over your local network or over the internet. This requires that you have connected our DVR to your router and properly configured it to work with your network by setting its IP address, if necessary. In a world where technology is advancing at breakneck speed, terms like AI, ML, and automation dominate the conversation, especially in video surveillance. But amidst this tech frenzy, one fundamental process remains underappreciated: ‘PLAYBACK’!

Types of monitor outputs on DVRs

To ensure you understand the correct monitor connector terminology please take a look at the image below. Surveillance camera recorders by CCTV Camera World have HDMI and VGA video outputs. VGA supports a maximum output of 1080P resolution, while HDMI can support up to 4K depending on the model of the recorder that you purchased.

How to troubleshoot

Here is a list of troubleshooting steps on how to resolve monitor issues you may be having with your DVR.

1.   Find the make and model of your monitor(s)

2.   Google the make and model and determine what is the max resolution support by each monitor

3.   You cannot set your DVR or NVR display resolution to be higher than the highest resolution your monitor will support. We recommend selecting 1920x1080 as the display resolution to be sure. The following section explains in detail the different way to set the monitor resolution on a security camera recorder.

 

How to set the monitor resolution on a security camera recorder

Method 1

How you change the resolution on your recorder will depend on whether you can still see a display output and menu screens on any of your current displays. If you have no video then you will need to connect your recorder to your local network and access the recorder using a web browser on a Windows PC to set the correct display output. Note that older recorders require Internet Explorer for web access, while newer recorders are compatible with Chrome, Safari, and Firefox.

First place the recorder on the network if you already have not. If you are unfamiliar with how to connect the recorder to the network, below are quick and easy to follow videos on how wire the recorder to your network, and enable DHCP to get a dynamic IP address from your router.

The first step is to connect the NVR to the main router in your network. This would be the router your PC is connected to so you can access the recorder over the LAN (Local Area Network). It is imperative that you are on the local network to follow this method.

Next enable DHCP inside the recorder's menu interface using the menu interface shown on your monitor. We usually enable DHCP already on recorders we ship. You may find it already enabled. Note the IP address of the recorder as shown in the last step in the video below. You will need that IP address to access the recorder over the network.

Once you have the recorder on the network, use the IP address assigned to the recorder over the local network by your router to access the recorder using a web browser such as Firefox, Chrome, or Edge.

If you purchased from CCTV Camera World, the video below provides comprehensive instructions on how to change your DVR recorder's resolution using Firefox. You can Chrome or Edge as well. If you have any questions, please email our support team on ssaintegrate@gmail.com

Method 2

If you still have video output being displayed by one of the monitors on the digital video recorder or network video recorder, then it's simple to change the display resolution using the menu interface on the recorder. Depending on whether you have a DVR or NVR, the steps to change the display resolution are slightly different.

Changing the monitor resolution on a DVR or XVR

Keep in mind that 4K DVR recorders are capable of 4K display output over HDMI, but the VGA port cannot display 4K video. VGA technology maxes out at 1080P. Once you set the main HDMI output to 4K, the VGA port will automatically become disabled. The process to have either or both the HDMI or VGA port working is explained in the video below.

Changing the monitor resolution on a NVR

Similar to the DVR and XVR recorders we carry, the NVR recorders offer both HDMI and VGA output. Some NVR models even have second HDMI port that is a spot monitor, and that is limited to 1080P just like the VGA port.

What Can VMS for CCTV Do?

What Can VMS for CCTV Do? 

Surveillance cameras are almost taken for granted as an integral part of your commercial security system. No matter your business size, you’ve got cameras monitoring critical points in your building. The bigger your business, the more cameras you need, and the more you need to watch them. At a certain point, you’ll need a Video Management System (or Software) to comfortably operate your cameras. A flexible video management system platform doesn’t just tie your cameras together, though – it brings a few unique security solutions to your business, as well.

All NVRs and DVRs come with a rudimentary VMS for CCTV pre-installed. They’re great for smaller systems, but the functions are limited and it becomes difficult to manage footage from surveillance systems with a lot of cameras. These pre-loaded programs generally only allow you to edit basic camera settings, view live feeds, use PTZ controls, play back recorded footage, and save and export clips and screenshots.

An Open VMS for CCTV is a system that can interface with cameras and DVR’s/NVR’s from a variety of manufacturers, reducing or eliminating the hassle of dealing with proprietary cameras and systems. You don’t have to use an Open VMS, but if you’re looking for a full video management suite you’ll likely end up with one. Even if you don’t have systems from different manufacturers, the flexibility of open systems makes them valuable assets for business security.

The catch with video management systems is the initial setup and long-term maintenance. Open VMS for CCTV platforms are difficult to create and maintain, since they have to be compatible with so many brands and types of cameras. Installing them and making sure all the cameras work properly can be quite a chore.

Image Correction and Dewarping

A VMS for CCTV can also correct lens distortion common to wide-angle cameras. Fisheye lenses in particular produce a unique, heavily warped 360° image. They can be used to cover an entire room when mounted on the ceiling, but picking out details from the feed can be a challenge. video management system dewarping straightens and flips the contorted image, giving you a clearer view without adding cameras.

Some VMS programs can even create multiple image channels from one fisheye camera. The corrected images simulate multiple cameras without the trouble of paying for and installing them. You only need to store one recorded file for several feeds, cutting down on your storage needs as well.

Distributed Processing Power

With larger camera networks, a single NVR or DVR might not be enough to handle all your security cameras. Without a VMS for CCTV, you’d have to use each recorder separately to change settings and view your footage. A unified platform to manage your surveillance system makes curating your video a lot easier. A single technician or guard can monitor or review all your feeds from a central office without constantly switching servers.

Multiple Site Management

A central VMS for CCTV can handle not only multiple NVRs, it can manage multiple locations, too. This is critical for any company with more than one site, whether it’s offices, stores, warehouses, workshops, or factories. You’ll be tied into every local server, meaning you can access any site’s footage from your central security office.

Storage Redundancies

Your NVR generally stores its footage on its own internal hard drive, and it doesn’t store it forever. If that hard drive fizzles, your data goes with it unless you remembered to make regular backups. With a video management system, you can send the footage to a dedicated storage server with RAID redundancies, ensuring your data is secure.

Alarm, Audio, and Access Integration

Some VMS programs include options to integrate your other security systems, unifying your interface even further. Compatible systems can activate devices based on camera inputs, such as remote lighting, alarms, sirens, 2-way audio, or camera recording. Your access control system can also be connected to your VMS, triggering a recording or an alarm when a set of credentials is denied. If your systems are fully compatible, you can even manage your alarms and access control from the VMS.

Mobile Recording

Standard NVR/DVR VMS’s allow you to connect your smartphone and view your feeds remotely through an app. A full VMS for CCTV connects you to your main server and manage your entire security system with a few extra features. The latest VMS apps let record video directly through your phone and store it on your server, effectively turning your security guards into roving cameras.

Point-of-Sale Integration

For retail businesses, VMS programs can connect with the register to provide real-time Point-of-Sale data. Transaction analysis becomes much easier, allowing you to investigate or keep an eye on discrepancies.

Difference Between CCTV and Surveillance Cameras?

When it comes to matters of security, there is a great deal of misunderstanding regarding the distinction between closed-circuit television and surveillance cameras. In spite of the fact that many people use these phrases synonymously, there is a significant difference between the two.

In this article, we will go over the key distinctions between closed-circuit television (CCTV) systems and surveillance cameras, and then we will assist you in selecting the system that is most suited to meet your requirements and how to Select The Right CCTV System.

What Is CCTV?

A CCTV system consists of a number of cameras to record activity, a digital video recorder (DVR) to store footage, and a monitor to view the recordings. You can also add security features like motion detectors and alarms.

Most people install CCTV systems for security purposes. They deter burglars and can help identify criminals after the fact. But they have other uses too. For example, you can use them to keep an eye on employees or children.

CCTV systems come in all shapes and sizes. They can be as simple as a single camera connected to a DVR, or they can be more complex with multiple cameras, different types of storage, and remote viewing capabilities. The type of system you need depends on your specific needs.

Installing a CCTV system can be a great way to improve security at your home or business. But it’s important to make sure you understand all the ins and outs before making any decisions.

What Is A Security Camera?

The word “security camera” is often used, although many people have no idea what they are. Monitoring and recording activity in a certain area is the primary function of security cameras.

They’re commonly found in public locations like shops, banks, and other establishments of a commercial nature. The usage of security cameras to discourage criminals and safeguard families is becoming more common.

There are a wide variety of security cameras to choose from. Small enough to fit in your hand, yet with a wide range of size options.

The region you want to keep an eye on will dictate the kind of camera you require. In order to watch your front entrance, you’ll need a different kind of camera than you’ll need to monitor your backyard, for instance.

Wireless and wired security cameras are available. A cable connects a wired camera to a recorder, such as a DVR. Wi-Fi is a common method of transmitting footage from wireless cameras.

Wireless cameras are preferred by many people since they are easy to set up and can be put anywhere in your house or company.

Analog and digital security cameras are two of the most common varieties. Analog cameras record footage using an analogue signal. Unlike digital cameras, this sort of camera is older and less prevalent.

What is The Main Differences Between CCTV and Security Camera

CCTV cameras, or closed-circuit television cameras, are a type of security camera that is typically used in public places in order to deter crime.

Security cameras, on the other hand, can be used in both public and private settings and are often used in homes in order to provide extra security. Here are five main differences between CCTV cameras and security cameras:

-CCTV cameras typically have a wider field of view than security cameras.

-CCTV cameras are usually mounted on ceilings or high up on walls, while security cameras can be placed anywhere that provides an adequate view.

-CCTV footage is usually monitored by security personnel in a separate location, while many home security systems allow users to monitor their own footage remotely.

-CCTV cameras typically record footage continuously, while security cameras can be set to record only when motion is detected.

-CCTV cameras are usually larger and more noticeable than security cameras.

Both CCTV cameras and security cameras serve an important purpose in terms of security. It’s important to choose the right type of camera for your needs in order to ensure that you’re getting the most out of your investment.

Ports on Security Camera NVR & DVR

Ports on Security Camera, NVR & DVR? 

When you receive your DVR you might be wondering what some of the ports are for. This article will explain some of them, the reason they are their as well as a little bit of history.

USB = Universal Serial Bus

Universal Serial Bus is an industry standard developed in the mid-1990s to replace the slower serial and ps2 communication ports on a computer.  The purpose was to be able to attach devices like a mouse, a keyboard, disk drives, network adapters, portable media players, and other devices that help qualify the word Universal in the name of the port.  It has become such a standard that it has evolved over the years as USB 1.x, USB 2.0, USB 3.0, USB 3.1, and USB Type-C.  The DVRs and NVRs continue with this trend by offering USB ports for connecting a mouse and flash drives or hard drives to the unit by using one of the available ports.  Unfortunately, USB keyboards are not supported by the operating system and only the online keyboard is available for entering data.  DVRs and NVRs are very similar to computers, so the device needs to be supported in the operating system.  This matters especially when connecting drives in the sense that you could try to use a USB drive that is too new for the unit.  A DVR or NVR manufactured during a certain era will only support flash drives and hard drives with sizes appropriate to that era.  For example, you will not find a 64GB flash drive or a 6 Terabyte hard drive in 2007.  There is no harm plugging in a USB drive to see if it is recognized since the port is plug and play.

Ethernet Port

An 8P8C (8 position 8 contact) modular connector, often called RJ45 (Registered Jack 45), has become an extremely important plug since the world wide web is connected with this standard Ethernet port on all kinds of devices.  Our DVRs have one Ethernet port so that they can connect to a router for access to the unit from the world wide web.  Our NVRs have the same port, and may also have power over Ethernet ports (POE) for cameras to connect to it for power and video data transmission.  You can buy an 8 channel NVR, for example, that has a built-in 8 port POE switch that allows you to plug 8 IP network cameras into the back of the unit.  You can also buy an 8 channel NVR that does not have any built in POE ports, so the video data would need to be networked back to the NVR.  This can congest a network if you have other computers and devices using the same routers and switches, but there are ways to design your network topology to reduce or separate traffic.

BNC Connector

The BNC connector derived its name from Bayonet Neill–Concelman, which is a combination of its bayonet mount locking mechanism and its inventors, Paul Neill and Carl Concelman.  The BNC connector is a quick connect radio frequency connector commonly made in 50 and 75 ohm versions used for coaxial cable. 

This connector has become the heart and soul of the analog and HD-CVI DVR because of a quick plug and play connection option.  Many people like to use existing coax cable and continue to use it with new technologies like HD-CVI rather than mess with a complete overhaul to an IP technology system.  While IP may be the future, this connector has found new legs with new technologies and should remain viable for years to come.  As long as coax cable still exists, the BNC connector will remain the default option.

RCA Connector

An RCA connector is designed to carry audio and video signals, and received its name from the Radio Corporation of America in the early 40s when it was designed to be an internal connector in home radio-phonograph consoles.  This port has evolved over the years to encompass video in the famous red, white, and yellow composite video.  Our DVRs and NVRs use the connector for audio-in and audio-out primarily since video on our DVRs is covered by the BNC port and NVRs use networking to transmit video.

HDMI Port

HDMI stands for High-Definition Multimedia Interface, and it is a proprietary interface designed for sending video and audio to and from HDMI compliant devices.  The video is uncompressed and the audio can be compressed or uncompressed.  Our DVRs and NVRs have this port as a connection option to a TV or monitor for viewing the live video or playback, as well as adjusting the settings of the unit through the menu options.  The main improvement of this port over VGA, for example, is the ability to do high definition without video loss, which allows us to see higher quality video.  This means that we can see more cameras on the screen at one time clearly and see more detail.

In Summary

There were many ports used in the past that are now likely on the way out.  Most notably is the RS485 connector that is used to control the PTZ cameras.  With Ethernet IP camera and HD-CVI camera technologies taking off, connecting a PTZ is now done over the one cable with no additional cables needed for PTZ control.  They should still be present on hybrids and tribrids, but anyone buying a new system should opt for one of the new technologies since video surveillance is about protecting assets.  VGA should hang around a little longer, but HDMIs ability to handle high definition video without video loss and audio on the same cable, make it very convenient.  RS232 / Serial, PS2, LPT, are all in the port graveyard, but there are likely still some machines out there that have them.

No doubt that new standard ports will come, as they are always being invented or improved.  The research and development teams at all technology companies are working towards the next big thing, so that they can create a new standard port for years to come.  DVR and NVR companies will incorporate any new port into their system that is useful as it grows in popularity.  For example, if a port replaces USB 3.0 for connecting external hard drives, that would become a standard very quickly.

Some software based port are required to come online of IP camera, DVR or NVR. One for the HTTP port (port 80) and one for the TCP port (port 37777). You will find that the majority of network devices which are accessible using an Internet browser will be set as standard to port 80, including IP cameras and routers etc. This is due to the standard port for HTTP, or information being displayed through an browser, being port 80.

HTTPS (Hypertext Transfer Protocol Secure) is a secured HTTP version where all traffic is bind with strong encryption that passes through Port 443. This port is also connected with TCP protocol and creates a secure connection between the webpages and browser.

Port 554 RTSP for communication between the Content Server and the Wowza Media Server. Needs to be open between the Content Server and the Wowza Media Server.

TCP port 9530 uses the Transmission Control Protocol. TCP is one of the main protocols in TCP/IP networks. TCP is a connection-oriented protocol, it requires handshaking to set up end-to-end communications. Only when a connection is set up user's data can be sent bi-directionally over the connection.

Attention! TCP guarantees delivery of data packets on port 9530 in the same order in which they were sent. Guaranteed communication over TCP port 9530 is the main difference between TCP and UDP. UDP port 9530 would not have guaranteed communication as TCP.

A web server would typically have this open and listening if there are any types of these activities. If the machine is windows you can run "netstat -a -b -v -n", to display the processes associated with a particular open port.

A backdoor was found in Chinese-produced DVRs and NVRs that secretly allowed access to the recorders. While it was first attributed to Huawei (HiSilicon), Huawei subsequently refuted their involvement.

How the Backdoor Works

The backdoor uses port knocking via the management port of vulnerable equipment. A series of commands are sent to the device via the management port, TCP 9530, which in turn opens telnet. When telnet is enabled the attacker can use one of six hardcoded root credentials to gain full control of the vulnerable device.

The skill level needed to exploit this is low and similar to the skill level needed to exploit the Dahua Wiretapping Vulnerability from last year, requiring a limited working knowledge of python. A proof of concept is available, which is used to:

• Send a command to open Telnet on the target device (OpenTelnet: OpenOnce)
• Use a pre-shared key for access (2wj9fsa2)
• Receive an 8 character number / respond with that number + PSK
• Open a Telnet session with the device
• Login with 1 of 6 hardcoded root accounts

Major Chinese Manufacturer Impact Unlikely

Major China manufacturers like Dahua, Hikvision, Uniview are not impacted, from everything we have seen. We executed the proof of concept code from the disclosure on multiple devices and were unable to gain access using the backdoor.

The backdoor primarily impacts devices using HiSilicon SOC with Xiongmai software, which is dozens of small OEM manufacturers, using minimally modified OEM firmware, Open Source OS and drivers, and enabling telnet on port 9530.
