CCTV Kits
CCTV Kits provide a comprehensive surveillance solution with 24/7 monitoring. They include all the necessary components for remote image transmission and can be integrated into smart home systems.
Camera housings and brackets are built of strong material to protect against vandalism. They also ensure that the cameras are weather-resistant.
Cameras
CCTV systems monitor your premises by picking up a sequence of images and transmitting them as signals. The signal passes through a display device, like a monitor, which displays the video footage. These devices are either wired or wireless and can work over a wide area.
If you want a system with fewer cables, choose a wireless CCTV kit that uses Wi-Fi technology to broadcast the video over a wide range. These kits CCTV Kits are ideal for businesses that require remote monitoring of their premises.
Alternatively, you can opt for a wired CCTV system that connects to the recorder using coaxial cables. These cables are used to carry both power and video. You can also buy cameras with PoE, which enables them to draw their power from the Ethernet cable.
A security camera can be fitted with a hard disk to store the footage that it captures. CCTV hard disks are specially designed to be reliable for continuous 24/7 recording. They are made to be more durable than regular computer hard disks and come in different sizes and capacities.
NVRs
NVRs included in CCTV kits serve as hubs for IP-based surveillance systems. They allow you to save video locally on your computer, tablet or mobile device for viewing anywhere, anytime and without a monthly subscription fee. Some also feature motion detection, remote access and AI-enhanced camera streams for advanced security monitoring.
Look for NVR bundles that use Power over Ethernet (PoE) to connect cameras to the recorder, a cable run that minimizes wiring and is easier to set up than analog connections. This also keeps cameras on their own Wi-Fi network rather than sharing the same frequency as your home or business Wi-Fi, which can cause issues with streaming and other services.
Other options use dedicated wireless NVRs that create their own Wi-Fi networks, which can be a more straightforward choice for spaces such as temporary or leased properties. For example, a system like the WNQ28 from xmartO uses two antenna to create its own Wi-Fi network that can connect multiple cameras and viewers and avoids having your home or business Wi-Fi become too congested.
Hard Drives
The DVRs and NVRs used in CCTV systems require a lot of data storage to record the footage captured by cameras. This is why they have internal hard drives.
Unlike PCs, where hard drives are biased towards read capability with small-block, random data transfers, video surveillance requires storage engineered for write performance with larger, sequential block writes. These are the types of workloads that can accelerate hard drive degradation.
In addition, the hard drives in CCTV system are usually operated under continuous duty and subject to high ambient temperatures that affect their performance. This makes it important to use a hard drive specifically designed for these conditions.
Seagate makes a reliable surveillance hard drive called Skyhawk that is recommended by most major security camera equipment manufacturers. It features enhanced ImagePerfect firmware to ensure no dropped frames are lost during recording. It has a workload rating three times that of desktop drives and comes with a 3-year limited warranty. The 2TB model can store about a week of footage. It also works well for storing HD surveillance videos.
Connectors
For CCTV kits to function correctly, they need to be connected to monitors and recorders. Luckily, there are cable and connection types available that help make this process simple. These are often included in the kit, making them easy for end users to set up and use.
These cables come premade with connectors already attached, which saves time and effort during installation. They’re also thin and flexible, making them ideal for a wide range of site conditions. They can be used to transmit audio and video signals or power to a camera.
BNC connectors are the most commonly used CCTV camera connection type. These can be used on RG59 coaxial cables to transmit video signals between CCTV Kits security cameras and the CCTV DVR, or on ethernet cables to transfer data. Some ethernet cable types are shielded, which helps to reduce electromagnetic interference and ensures a clear signal. Other ethernet cables include power over ethernet (PoE), which allows for the transmission of both power and data on one wire, reducing cable runs and simplifying installations. These are typically referred to as PoE CCTV systems.
Installation Handles
Most kits include an LCD flat monitor that can be used to display live feeds and playback recorded video locally. It’s useful for troubleshooting any problems with your camera system and allows you to easily control your cameras from one central location.
Depending on the type of cameras you choose, they may need to be wired for signal and power. Most analog CCTV systems use coax cables, while DVRs and NVRs work with ethernet cables or wirelessly. You can also get “Siamese Cable” that includes both the coax and a set of power wires in the same cable for easier installation.
Depending on how complex your installation is, you may want to consider hiring a professional installer for your CCTV hardware. This will help ensure that everything is installed properly and will continue to function correctly for the long term. It will also minimize the risk of any potential issues in the future. An NSI accredited professional can also help you make the best choice of equipment for your home or business. They will be able to provide recommendations based on your specific needs and budget.
