An IP telephone system uses packet-switched Voice over IP(VoIP) or Internet telephony, to transmit telephone calls over the Internet, as opposed to the circuit-swithed telephony used by the tradtional Public Switched Telephone Network (PSTN). IP telephone systems typically comprise of a VoIP private branch exchange (an IP PBX) and desktop VoIP phones (IP Phones) that connect to a service provider, via a Local Area Network (LAN).

All businesses can benefit from some sort of phone system that can present themselves in a professional manner.Clients are able to reach you on a business line that is often by an automated attendant is an excellent way to achieve that. IP phones provide the features and tools that small businesses find most vaulable, such as voicemail to email, call forwarding, call screening, music on hold and online faxing.

WiFi is a technology that allows electronic devices to connect to a wireless LAN (WLAN), using either 2.4 or 5 GHz radio frequencies. A WLAN should be secure, and password protected. If left open, it would allow any device within its range to access the resources of the WLAN network.

Wi-Fi 6 is the latest and greatest new wireless networking standard. ● Greater data transfer speed. The theoretical speed of WiFi 6 is 10Gbps. It achieves this speed increase by combining the 2.4GHz and 5GHz spectrum bands and employing multi-user, multiple-input, multiple-output technology for both uplink and downlink data transfers. More efficient data encoding leads to the higher throughput. More powerful chips used to encode and decode signals allow more data to be carried by the same radio waves. A single device can achieve up to 40% faster data transfer when using WiFi 6 versus WiFi 5. Even 2.4GHz networks will experience increased speeds when using a WiFi 6 router. ● Increased battery life Wi-Fi 6 lets devices and routers schedule communications with a feature called Target Wake Time, make any connected device more power efficient. This will conserve power, as it means the Wi-Fi radio spend more time in sleep mode. And that means longer battery life.

Unmanaged Switches ● To provide Ethernet devices with network connections so they can communicate with one another. ● Not allowed for configuration or require set up, unable to control network traffic. ● Simply plug and play. ● Suited more with small networks, to edge services or add temporary groups of devices to a larger network. ● Less expensive than managed switches. Managed Switches ● Offers additional feature that unmanaged switches cannot. ● Able to manage, configure, monitor and troubleshoot issue with networks. ● Each switch has its own IP address for identification and addressing. ● Able to create traffic controls, prioritize channels based on the importance of data, investigate performance problems, remotely deploy fixes and even create new virtual networks for segmentation purposes. ● Provide a layer of security that can monitor unauthorized access and encrypt communication. ● Feature built-in redundancy so data is duplicated and can be recovered if a device or network fails. ●In terms of applications, managed switches are most often deployed as part of the industrial network backbone to monitor and control traffic. They’re also used to connect mission-critical devices to networks.

CAT6 cables, also called Category 6, provide lower crosstalk, a higher signal-to-noise-ratio, and are suitable for 10GBASE-T (10-Gigabit Ethernet) up to 55m or 1GBASE-T up to 100m. As a means of future-proofing your network, CAT6 is generally a better choice and worth the small premium in price. CAT5e and CAT6 cables are both backwards compatible, which means newer CAT6 cables can be used with older CAT5e, CAT5 and even CAT3 equipment.

Power over Ethernet (PoE) capabilities let you direct power out of the switch and into another device. This allows you to put network endpoints in areas that aren't easily accessible or are far away from other power sources. You can use this to setup wireless access points, IP Surveillance systems, and VoIP phone networks across the office.

Router is mainly used to route network traffic from one network to another network. Router is actually a small computer that can be programmed to handle and route the network traffic. It usually connects at least two networks together, such as two WANs or a LAN Hub is commonly used to connect segments of a LAN (Local Area Network). A hub contains multiple ports. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets. Hub acts as a common connection point for devices in a network. Switch A switch is able to handle the data and knows the specific addresses to send the message. It can decide which computer is the message intended for and send the message directly to the right computer. The efficiency of a switch has been greatly improved, thus providing a faster network speed.

Digital access control systems manage who, where and when somebody is granted access to enter or exit a properly. Types of access control include password, pin code, key card, mobile phone or biometric (fingerprint, palm reading, facial or iris recognition).

There are some door access control systems that use the Bluetooth connection to your smartphone for the credential. The door reader can connect to an app running in your IOS or Android smartphone. In most cases, you enable the app when you are near the door, and by holding close to the door it will be identified by the door reader.

Access control covers a range of door control readers. There are readers that use a PIN to gain entry. The next level uses a credential such as a card. The most secure level uses biometrics such as facial recognition or fingerprints. The most popular door readers use credentials. Using a card is more secure, but what happens if someone loses the card or gives it to someone else. Biometric readers capture the physiological characteristics of a person and make them the most secure form of door access control.

An IP based voice and camera communications system for use within a building or collection of buildings that can provide access control and live monitoring. It can be integrated with an existing Access Control, CCTV or Security System. Remote access can also be available through your smart phone.

Wired System ● Wired solution considered more reliable and secure, especially over long distances. If you need an intercom system for a large building, multiple buildings, or on an exterior gate, a wired system will give you unmatched reliability over vast distances. Wireless System ● Wireless solutions are simpler to install and manage. They still require power for the device. Since they use radio waves to communicate, the distance between speakers can cause connectivity issues. Wireless systems are best for small properties that need a simple intercom solution that have power already provided.

Absolutely, you can integrate intercom systems with just about any other type of security solution. One of the most common integrations is with an access control system. Once integrated, you can validate visitors before they access your property. When someone comes to the front door, you can talk to them (or see them if you choose a video intercom) to make sure they are who they say they are. Then, using the access control integration, you can push a button to unlock the door and let them in. Other integration can be with a CCTV system or security system.

It depends on the system and features you choose. The only way to get remote access to your intercom system is to install one that can connect to the internet. That way, you can log into your system from any device to use your intercom and talk to people at your property, even when you’re not there. Standard intercom systems don’t typically offer internet connectivity. If remote access is something that’s important to you, make sure you choose a system with the right features.

The best way of protecting your family and assets from burglars is to invest in a security system to monitor your home. There are instances when even though there are people inside the house, burglars still intrude and find ways to get into the house and take what they can. With different types of detectors, a security system can notify you, your family, or your neighbors of the intrusion.

Security smoke is a thermally generated white fog, aimed at inhibiting intruders from accesing items to steal. Security smoke is a good option in areas of high-value goods, and recommended by police and insurers. It consists of glycol or glycerine mixed with distilled water, which vaporises and then condenses in the air.

CCTV cameras are used to view and monitor areas to ensure that they are safe and secure.

CCTV can protect your business, home or any other private property. CCTV is now more accessible due to its low prices, easy installation and the technology allowing you to get HD pictures now. Working in conjuction with an alarm system, CCTV makes a great deterrent for would-be thieves. CCTV for your business can help ensure your employee and customer safety, maintain security around any stock and protect your property.

● Simple set up, just plug directly into the DVR with coaxial cable and require less programing. ● Lower band width because analog camera transmits video file to the DVR over coaxial cable, transmission takes less band width, putting less pressure on the network. ● Requires more cabling for both the power supply and the DVR. ● Analog cameras have a maximum resolution, which impacts zooming. ● Analog cameras have limited throughput. Therefore, the higher camera resolution, the lower the cameras can be used before compromising bandwidth. ● Analog cameras are more suitable for smaller, simpler surveillance setups. ● For video capture, analog cameras record onto a DVR. ● Analog cameras are a good option for smaller surveillance systems of 5-16 cameras. Therefore, they are best suited for small retail stores, convenience stores, small businesses, or home security camera systems.

● Offer resolution up to 12MP (4000x3000). ● More options and features are available as technology advances, including multiple users and department access. ● Require less wiring, IP cameras are simpler to set up. ● They connect to an existing network with one cable that provides power, video and data. (There is no need to invest in new cabling). ● With power over Ethernet (PoE), a power outlet close to the camera is no longer needed. ● Flexible and scalable, IP cameras offer more expansion options because their cabling requirements are less complicated. ● Better video quality, IP cameras are available in high resolution, up to 12MP, yielding better quality video. ● Many models offer digital and optical zoom and provide more usable and meaningful footage. ● Tend to cost more and require more bandwidth for video transfer over a network. ● For video capture, IP cameras process and compress the video and then send it to a video recorder (NVR). ● IP cameras are better for more significant sites with more cameras, such as large villas, industrial businesses, construction sites, and large retail locations.

DVR is short for Digital Video Recorder, a device that records CCTV camera footage onto one or more hard disks. It has a number of BNC connections to connect to the cameras. Our DVR's can support 4,8, 16 and 32 channels (connections) on the BNC ports whilst several of our DVR's can also connect to IP cameras over the network.

NVR is short for Network Video Recorder, an IP camera recording device. An NVR offers the same functionality as a DVR, as it records CCTV camera footage, but it is tailored for IP CCTV cameras. NVR's will have more AI functionality built in such as face recognition, privacy protection, stereo analysis, ANPR, illegal parking just to name a few.

Definitely, as long as there is network connectivity then you can use the mobile app on your mobile device to view live or recorded footage.

Yes, you can digital zoom on any camera. If you require optical zoom then this is only available on a vari-focal or PTZ camera.

This depends on the number of cameras recording at the same time and the level of quality/detail they record at, as well as the hard drive capacity.
