The Encoding menu has several settings that can be set. A good understanding of the following settings is important in getting the most out of our security camera system purchase from CCTV Camera World.

Codec – is the video encoding compression method used. It can be H.265 or H.264 depending on the model of the camera and recorder. H.265 video encoding provides up to 50% bandwidth savings over H.264. To use H.265, both the camera and surveillance recorder have to support H.265.
Resolution – is the size of the picture in pixels. When comparing video at the same angle of view (zoom length), higher resolution video provides facial detail farther away when using digital zoom for magnification. The resolution option available in this section depends on the camera resolution and whether it is compatible with the DVR or NVR. For example, a 12MP IP camera is not compatible with a 4K NVR that supports a maximum of 8MP. You would have to set the camera to 8MP or 4K resolution to use it with a 8MP 4K NVR. Likewise, a 4MP HDCVI camera is not compatible with a 1080P DVR unless the camera can be set to 1080P using a 4MP HDCVI DVR.
Frame Rate – allows for adjusting how many frames per second (fps) are recorded from your camera. It also depends on the capabilities of the camera and DVR. 30fps is Real Time video without any frame skipping. To conserve hard drive space 1080P and higher resolution cameras are commonly recorded at 15fps. You would use 30fps only for quick motion applications like license plate capture cameras or for cameras overlooking a cash register. Here is a quick video demonstrating the differences between video filmed at FPS settings of 30 thru 3fps.

Bitrate – is the amount of data per second that is saved for each security camera. Having a low bitrate would cause the video to be very pixelated as the video is compressed more. For example, attempting to save H.264 encoded 4MP resolution video of 20fps at 2mbps would cause the video to be pixelated and seem of poor quality. A bit rate that is too high would have diminishing returns as it wouldn’t improve video quality beyond a certain point.
We recommend first selecting the codec, resolution, and frame rate; our digital video recorders will recommend a bit rate based on the selected settings. As a guide, use the below bitrate settings for optimal video recording if hard drive space is of ample capacity in your system.

Codec	Resolution	Frame Rate	Bitrate (kbps)
H.264	960H or D1	30fps	1024
H.264	720P	30fps	2048
H.264	1080P	30fps	4096
H.264	3MP	20fps	4096
H.264	4MP	20fps	4096
H.264	8MP	15fps	8192
H.264	12MP	15fps	10240

The digital video recorders in our systems even allow multiple recording methods for each camera. For example, cameras can be set to record all the time or during a portion of the day using the scheduled recording method, while also recording upon motion detection. This preserves video integrity in case a motion event is missed, and is very helpful when reviewing recorded security footage to allow the user to skip to points in the timeline when motion is detected. The video tutorial below is an in-depth guide on how to set the different recording methods for each camera in your surveillance system.

6. Playback Recorded Video on your Surveillance System

Encoding settings can be set individually for each camera channel. Depending on the maximum recording resolution supported by the recorder and the camera, our surveillance recorders allow up to 12MP recordings. All of our DVR and NVR recorders also have dual video encoding technology to provide two streams of video for each camera channel:

Main Stream – high resolution video stream that can be a maximum value equal to the resolution of the camera’s sensor, or a lower value selected by the user if bandwidth is being conserved.
Sub Stream – a lower resolution stream used when viewing multiple cameras in a grid on the computer or mobile device.

The in-depth video tutorial below discusses encoding settings available in your system and how to configure them.

4. Customizing Video Settings

You can playback one camera or multiple cameras depending on the resolution of the recording and the playback capability of the recorder that is part of your system. Our 4000 series NVRs support playback of up to eight 1080P channels, while our 5000 series NVR support up to sixteen channel playback at 1080P. Stronger playback capability is available when playing video over the network using our free computer client software to playback video on a PC or Mac workstation.

7. How to Download Video from a Security Camera System

It is important to understand the difference between digital zoom and optical zoom, and the fact that optical zoom can only be used in live view mode. Below is a detailed video demonstration of each type of zoom function and how both can be utilized during live view to see objects far away. Using a 4MP security camera mounted 7ft above the object of interest, we show the power of optical zoom provided by a motorized zoom security camera to view objects in fine detail.

A common misconception about our camera systems is that all cameras have to be the same resolution, which is not the case. Cameras of different resolutions can be used on the same recorder in any of our systems, granted the cameras are within the maximum resolution limit of the recorder. This is true for systems consisting of Tribrid DVR, XVR, or NVR recorders.

Before you are able to login to your camera system over the web, you need to login at the DVR or NVR itself using a mouse. Connect the recorder to a monitor that supports at least 1080P resolution. We recommend using a HDMI input capable monitor. Turn on the recorder and login using two possible login methods.

When logging in at the recorder, most of our surveillance video recorders allow quick access using a graphical pattern as a password.
You can also login using the username and password stated on the sticker located on the top of the unit.

Regardless of whether you have an IP security camera system or DVR camera system, both provide the user with two types of zoom:

Digital Zoom – digital magnification of the picture in live view or recorded video
Optical Zoom – physical zoom using a camera lens to zoom-in when viewing live video

Once security footage has been downloaded from your surveillance system, it can be reviewed on a Windows or Mac OS computer using our free playback software called Smart Player. You can download it here for Windows and Mac. Here is a list of features of Smart Player which makes our systems one of the best security camera systems in the industry for video archiving and review:

Video Grid and Timeline reconstruction
Playback one or multiple video files from one or multiple cameras in a grid
Synchronous or asynchronous video playback from multiple cameras
Digital Zoom and Pan
Video timeline with markers for motion events and video analytics
Up to 64X video playback speed
Frame-by-frame review

8. How To View Downloaded Footage from a Security Camera System

All of our DVR Systems and HD NVR systems allow multiple viewing options. You can view multiple cameras in a grid-view or view one camera at a time in full screen mode. Full screen mode also allows the user to listen to audio from security cameras with built-in microphone. To hear audio from cameras, all of the following conditions must be met:

Security camera has a built-in mic or you have an add-on security camera microphone connected to the DVR
Audio sensing needs to be enabled on the system from the Encode menu
A monitor with speakers is connected to the system using the HDMI video input

1. How To Login to a Security Camera System

Coax based cameras produce video that is encoded by the DVR, thus allowing picture quality to be modified before the video is saved by the DVR. In contrast, IP cameras encode video that is streamed to the NVR for saving the video stream; the video is not encoded by the NVR. Therefore, any changes made in the picture settings on the NVR must be communicated back to the IP security camera. If an incompatible IP camera is used with an NVR, such changes will not be communicated to the IP camera, and changes will not apply before video is encoded by the camera.

All of our security systems offer a variety of video recording methods. Each security camera can be set to record independently and the user has the option to choose from the following recording methods:

Stop – no video is recorded at all
Manual – continuous recording that is 24/7
Scheduled – the user can set different times of the day for each day of the week
Motion Detection – when pixel changes in the video are detected, video will be recorded automatically. The user can set different sensitivity settings and specify certain areas of the picture as motion zones for each camera to reduce false positive motion events.

In case you are unable to login due to a forgotten password, it is easy and secure to reset the password and gain entry into the unit. It is required that you be present at the recorder when following the video guide below on how to reset the login password. As shown in the video below, by answering some simple security questions you can quickly reset the login password.

2. Viewing Live Video and Audio on a Security System

We manufacture our cameras to produce the best possible picture quality automatically. Sometimes peculiar lighting scenarios in a scene may require customization. Our DVRs and NVRs allow multiple picture quality settings to be modified from the recorder as explained in the detailed video tutorial below. It is important to note that there is a difference in capabilities to modify image settings when comparing coax based cameras versus IP cameras.

CCTV Camera World’s security camera systems have a user-intuitive graphical interface to playback recorded video. Using a mouse connected to your recorder, it is easy to review recorded security footage in the Search menu. It takes 3 simple clicks to playback recorded video:

Select the month and day you would like to review footage from the calendar on the right hand side. The days highlighted in blue have recorded footage.
Select the cameras you would like to playback recorded video from by clicking the select boxes.
Select the point in the video timeline you would like to begin playback from.

When there is an incident, it’s important to have a camera system that allows easy download of security footage catching the perpetrator in the act. Our security camera systems are based on this simple principle to allow easy video download to a USB drive and playback on a Windows or Mac computer. To download video from any of our standalone recorders you will need a USB flash drive that is formatted with the NTFS or FAT file system. Our video guide on how to download footage from your security camera system walks you through the process.
