How to Upgrade Your Security Cameras/Systems

Before upgrading your security cameras/systems, it's important to assess your current setup and identify areas that need improvement.

Assessing current security cameras/systems

Here are the different scenarios you need to face when upgrading:

1. The current system have issues

The current system has problems with video quality, but the cables are good. To fix it, we'll replace everything with a new NVR that fits the size and capacity needed. We'll keep the existing cables and use them to connect the new cameras in the same places.

2. The system is generally fine but you need a higher resolution

The system is generally fine, but certain cameras require higher resolution for better face and number-plate recognition or improved video quality. Luckily, the existing cabling is in good condition. To address this, the proposed solution involves replacing the existing DVR with a new NVR that matches the required size and capacity.

Additionally, new high-definition IP cameras will be added based on the desired cabling preferences. If you previously used coaxial cables, it is recommended that you replace any existing coaxial cables with new Ethernet cables.

Upgrading security cameras/systems

1. Check which type of cable you have used:

Premade cables for security systems come in different types. You can match the cable information to your old monitoring system.

Thin premade cables designed for analog cameras have a slim profile and use aluminum strands instead of solid copper. They are suitable for low-resolution analog cameras but may have limited compatibility with higher resolutions.

On the other hand, HD premade cables for HD analog cameras are thicker and made of stranded aluminum wire. While they offer better compatibility with higher resolutions like 1080P or 2K, caution is necessary for long-distance installations to avoid potential issues such as ghosting.

For analog security systems, it is recommended to use RG59 coaxial cables, which provide better performance compared to premade cables. RG59 cables, with their thicker wire gauge, can even support 4K cameras until power supply limitations.

For IP network-based security cameras, Ethernet cables are commonly used. These cables connect the cameras to a network video recorder (NVR) in a Power-over-Ethernet system.

2. Replacing security cameras

Once you've determined the type of cable you have and its compatibility with cameras, it's crucial to decide on the desired power of your new security cameras.

As for the 4K security camera, if you have existing solid copper coaxial cable runs, switching to an Ethernet IP camera system is unnecessary. Solid copper coaxial cables can transmit 4K video up to 600 ft, although 4K coax DVRs typically record at a maximum of 7 frames per second. If you require smoother video, consider upgrading to an IP camera system.

For a full 4K camera setup, replacing existing coaxial cable with new Ethernet cable runs is recommended. Most Power over Ethernet (PoE) cameras are not sensitive to cable quality, but the maximum cable length is 328 ft before requiring signal extenders. Extenders can introduce issues with high-powered motorized zoom or PTZ cameras, such as voltage and amperage loss.

3. Replacing the DVR

Pay attention to the DVR or NVR specifications to know its maximum resolution. Connecting a higher-resolution camera to a device with lower-resolution support will result in errors or glitchy video.

Ensure compatibility between coax cameras and DVRs or IP cameras and NVRs. Different signal types like HDCVI, HDTVI, AHD, and CVBS are used in coax cameras. Using an incompatible signal type of camera can lead to error codes or distorted video.

What's Problem you will Run into When Replacing the Security Cameras？

When replacing security cameras, you may encounter certain challenges and problems that need to be addressed.

Analog coaxial cable system

Ensure that your power supply box is in good condition, providing the appropriate voltage and ample amperage to support the newly acquired cameras. Inspect the condition of your current cables and replace any faulty ones. Perform a bench test on any cameras suspected to be malfunctioning using a reliable, short cable, and test them with a dedicated power supply.

Password setting

When connecting the new cameras to the NVR or DVR, you may need to input passwords and configure access settings. Ensure you have the login credentials or follow the manufacturer's instructions to set up the cameras securely.

Power requirements

The new cameras may have different power requirements compared to the old ones. Ensure that the power supply box or PoE (Power over Ethernet) switch can provide the correct voltage and sufficient amperage to power the new cameras.

Network configuration

If the new cameras are IP-based, ensure your network is properly configured to assign unique IP addresses to each camera. This includes setting up DHCP (Dynamic Host Configuration Protocol) or manually assigning static IP addresses.

What Advanced Security Cameras Do you Need?

To enhance your security system, it is essential to consider various features when selecting advanced security cameras.

Resolution

Resolution holds utmost significance as it directly influences the clarity of the video. As stated earlier, you have the flexibility to combine and choose resolutions according to your needs. For instance, if your objective is to capture a clear view of a face that is approximately 20 feet away, a 1080P camera would be sufficient. However, if you require visibility of a face between 50 and 70 feet away, opting for a 4K camera would be advisable.

Night vision

Another important feature of advanced security cameras is night vision. Night vision lets the camera capture clear images and videos in low-light or complete darkness. By utilizing the ColorX technology, the security camera, such as Reolink CX410, provides reliable and comprehensive coverage regardless of lighting conditions.
