Security Cameras and NVR Kit Manufacturers
NVRs (network video recorders) capture and store footage from cameras. They also support AI functions like detecting movement and alert you to it.
They do this using a network switch and Ethernet cables. NVRs can be wired directly to cameras or to a PoE hub. This makes them more flexible than analog systems.
Analog Cameras
Analog cameras are the oldest type of security camera and still popular. They transmit data over coaxial cables and typically support standard definition (SD) video quality. The advantage of analog cameras is that they’re typically cheaper than IP models and are more widely available, making them an attractive option for businesses on a tight budget or those with existing cabling infrastructure. They also tend to have better motion detection capabilities than IP cameras and are able to capture images in low light conditions.
Many newer DVRs come with built-in analog to IP converters, allowing users to upgrade their current systems without having to replace all their cameras. This allows companies to take advantage of their existing wiring and eliminates the costs associated with installing new wire for power, connectivity and functionality.
A DVR with an analog-to-IP converter can accommodate a wide range of analog inputs, including legacy NTSC/PAL formats and high-resolution HD models. Many of the modern DVRs can even support 4K analog inputs, which offers a higher resolution than conventional analogue video.
Some newer analog cameras feature PoE connections, which means they can be powered over twisted-pair Ethernet cable instead of using a separate power supply unit. This is especially useful in installations where running electrical wire would be impractical or impossible, such as nvr kit manufacturers in older buildings with historic cabling infrastructure.
PoE (Power over Ethernet) Cameras
Power over Ethernet cameras are a good option for a number of reasons. Unlike traditional wired cameras, PoE devices can transmit video and data over one ethernet cable, eliminating the need for an extra power cord. PoE camera systems also offer a more stable connection than wireless options and are less susceptible to interference or other issues that can plague wireless networks.
When choosing a PoE system, make sure it includes a powerful video management system (VMS) that supports features like remote access, mobile alerts, motion detection, intelligent analytics, gateways, storage infrastructure, and more. These tools can help you reduce the time it takes to retrieve footage and improve your response times to any incidents that occur.
To use a PoE system, first you’ll need a network switch with power over ethernet built-in. This type of switch is called a Power over Ethernet switch or PSE and is designed to supply power to devices connected to it, including IP cameras. You can also use a PoE injector, which patched into your existing non-PoE network and provides power over ethernet to your devices.
Next, connect your cameras to the switch. Then, run a single ethernet cable from the switch to your NVR. Some NVRs are designed to be connected directly to a switch while others connect to the router and then to a switch to provide additional network connectivity.
Wireless IP Cameras
Generally speaking, IP cameras are capable of transmitting live video footage via Wi-Fi, Ethernet, or cellular networks. Most of the time, a wired network is preferred as it can provide the highest possible data transmission speeds with less chances for interference. It can also offer a greater level of security as only those with a direct connection to the cameras can access their footage.
Having said that, wireless systems are the most popular because they do not require any cables to be run through walls or attics. They can be placed anywhere there is an internet signal available. They can even be moved from one location to another at any time. This type of system is usually not recommended for outdoor use, however. Signal strength will suffer as a result of environmental factors such as brick and concrete walls, trees, and other large objects that can block or interfere with the wireless signal.
For those interested in a wireless system, we recommend choosing an NVR that is PoE capable. The Viewtron 32 channel NVR, for example, features built-in PoE ports that can be plugged directly into PoE IP cameras with CAT6 or CAT5e cable. This eliminates the need for running electrical wires and makes installation incredibly easy. It’s also worth noting that PoE cameras can be programmed to record automatically when motion detection is triggered. This can save valuable hard drive space, reduce recording times, and ensure that important events are not missed.
Storage
As systems users deploy more cameras, want higher image resolution, and archive video for longer periods, storage capacity is becoming an increasingly critical element of system design. The best way to balance quality, performance and cost is by using a dedicated NVR appliance (also known as an NVR/DVR) that’s designed for this purpose.
These specialized devices are low-power computers that run NVR software and perform live image processing and recording on local video data. This helps keep the overall system size, power consumption and video storage requirements as small as possible while ensuring optimal performance.
NVRs can use a variety of storage solutions, including internal or external hard drives, NAS and cloud storage. Each offers a different level of scalability and flexibility, with the cloud offering potentially unlimited storage capacity and low maintenance costs.
LS VISION is one manufacturer that’s taken a novel approach to NVR kit design. Their new battery camera system, the iCamPRO Smart Battery NVR Kit, turns the main annoyance of battery camera systems – limited recording times smart camera solutions due to insufficient battery power – into an advantage. Instead of a single camera battery, the system uses an NVR PowerHub that houses two additional batteries to extend recording time.
Another NVR with a similar idea is the Reolink RLK8-800B4, which includes an internal 2TB HDD and supports 24×7 recording of high-resolution surveillance footage. It’s a great option for store owners who prefer a simple, affordable and easy-to-maintain system. The system also benefits from UNV P2P cloud upgrade, which can update the NVR firmware remotely without any user interaction.
