Pan Tilt and Zoom Camera Installation
A PTZ (Pan-Tilt-Zoom) camera is a type of security camera that offers a range of movement options, allowing for a wide area of coverage. It can pan (move left or right), tilt (move up or down), and zoom (adjust the lens to make the subject appear closer or farther away), either manually via remote control or automatically through preset patterns and schedules. This flexibility, combined with high-quality imaging capabilities, makes PTZ cameras ideal for monitoring large areas and tracking movements in real-time.
Bullet and Domes Installation
A bullet camera is a type of security camera that is cylindrical in shape, resembling a bullet shell or a lipstick tube. These cameras are typically used for long-distance viewing and can be mounted on walls or ceilings. They are known for their straightforward installation and directional view, which means they point in a single direction once installed.
On the other hand, a dome camera is a type of security camera encased in a dome-shaped housing, hence the name. This design allows the camera to rotate and cover a wider field of view. Dome cameras are often used in indoor environments and are more discreet compared to other camera types
Turret Camera Installation
A turret camera, also known as an eyeball camera, is a type of security camera that features a compact, ball-and-socket design. This design allows the camera lens and the IR illuminators to rotate freely in the "eyeball" casing, providing flexibility for the direction of view. Turret cameras are versatile and can be mounted on walls or ceilings. They offer a balance between the discreet profile of dome cameras and the straightforward installation and adjustment of bullet cameras, making them popular for various surveillance applications. Furthermore, turret cameras are often designed to reduce the effect of IR glare and reflection, thereby providing good night vision capabilities.

⭐⭐⭐⭐⭐ Michael Simm
I’m not an industry professional, just a home owner who wanted some security in our barn and fields. I bought a pretty simple system, that was put together and quoted based upon my requirements. A single camera and a recorder. I also paid for the system to be configured before it was sent out to me.
The kit seems really good quality and Mike has been great helping me to link everything together and get it working as I decided I need to now I’ve actually got the kit. Really professional support, I couldn’t be happier and more grateful.
Great system and super support, absolutely no hesitation in recommending these guys.
What is CCTV?
CCTV stands for Closed-Circuit Television. It refers to a system of video surveillance that uses cameras to capture and record video footage in a specific area or location. Unlike broadcast television, where the signal is transmitted openly, CCTV is a closed system where the video feeds are privately monitored or recorded for security or surveillance purposes.
CCTV systems typically consist of cameras, recording devices (such as digital video recorders or network video recorders), and monitors. The cameras capture video footage of the designated areas and transmit it either through wired or wireless connections to the recording devices. The recorded video can be viewed in real-time on monitors or stored for later review.
CCTV systems are commonly used for various purposes, such as enhancing security and monitoring activities in public areas, businesses, homes, and other locations. They can help deter crime, provide evidence for investigations, monitor traffic, and improve overall safety and security.

Are CCTV cameras an effective deterrent to burglars?
Yes, CCTV cameras can be an effective deterrent to burglars and other potential criminals. Here's why:
1. Visible Presence: The mere presence of CCTV cameras can act as a deterrent. Burglars are more likely to avoid targeting properties that have visible cameras because they increase the risk of being caught and identified. The perception of being under surveillance can discourage criminal activity.
2. Increased Risk: CCTV cameras increase the risk for burglars. Knowing that their actions are being recorded can deter them from attempting to break into a property or commit unlawful activities. The fear of being captured on camera and leaving behind incriminating evidence can make burglars think twice before targeting a location.
3. Evidence for Investigations: In the event of a break-in or criminal activity, CCTV cameras can provide valuable evidence for investigations and prosecution. The recorded footage can help identify the perpetrators, their actions, and potentially lead to their arrest and conviction.
4. Remote Monitoring: With advancements in technology, many CCTV systems allow for remote monitoring. Property owners or security personnel can view live or recorded footage from anywhere using mobile devices or computers. This capability adds an additional layer of security and enables proactive response to potential threats.
5. Alert Systems: Some CCTV systems are equipped with motion detection or analytics capabilities. These features can trigger alerts or alarms when suspicious activity is detected. The immediate alert can prompt security personnel or property owners to take swift action, preventing or minimizing the impact of a burglary.
It's important to note that while CCTV cameras can be effective deterrents, they should be part of a comprehensive security strategy that includes other measures like proper lighting, access control systems, alarms, and physical barriers. A combination of security measures provides a stronger defense against burglaries and enhances overall security levels.
Why should I choose wired CCTV cameras over wifi cameras?
Choosing between wired cameras and Wi-Fi cameras depends on your specific needs and preferences. Here are some reasons why you might consider wired cameras:
1. Reliable Connection: Wired cameras provide a reliable and stable connection. They are directly connected to the recording device or network via cables, ensuring a consistent and uninterrupted transmission of video footage. This reliability can be important for critical applications where a stable connection is essential.
2. Better Bandwidth: Wired cameras typically offer higher bandwidth compared to Wi-Fi cameras. This allows for the transmission of high-quality video streams without significant degradation or lag. If you require higher-resolution footage or real-time monitoring, wired cameras can deliver better performance.
3. Enhanced Security: Wired cameras offer a higher level of security compared to Wi-Fi cameras. Since they are not connected to the internet or Wi-Fi networks, they are less vulnerable to hacking or unauthorized access. This can be particularly important in sensitive or high-security environments.
4. Long Distance Coverage: Wired cameras are suitable for applications where the cameras need to be placed far away from the recording device or network infrastructure. They can cover longer distances without experiencing signal loss or degradation, making them ideal for large properties or areas with challenging wiring conditions.
5. Power Supply: Wired cameras are often powered by the same cables used for data transmission (e.g., Ethernet cables), eliminating the need for separate power sources or batteries. This simplifies installation and maintenance and ensures continuous power supply to the cameras.
6. Reduced Interference: Wired cameras are not susceptible to wireless interference, which can affect Wi-Fi cameras. Interference from other electronic devices or neighboring networks can impact the reliability and performance of Wi-Fi cameras, while wired cameras are not affected by such issues.
What's the difference between a DVR and NVR system?
DVR (Digital Video Recorder) and NVR (Network Video Recorder) are two different types of video recording systems used in CCTV surveillance. Here are the key differences between them:
1. Analog vs. IP Cameras: DVRs are designed to work with analog cameras, which transmit video signals in analog format. NVRs, on the other hand, are designed for use with IP (Internet Protocol) cameras that capture and transmit video digitally over an IP network.
2. Video Encoding: DVRs receive analog video signals from cameras and convert them into a digital format for recording. NVRs, on the other hand, receive already encoded digital video streams from IP cameras, eliminating the need for additional encoding.
3. Network Connectivity: DVRs typically do not have built-in network capabilities and primarily function as standalone systems. NVRs, on the other hand, are equipped with network interfaces and can connect directly to IP cameras over a network infrastructure.
4. Camera Compatibility: DVRs are compatible with analog cameras, including older models, but not with IP cameras. NVRs are designed specifically for use with IP cameras, providing compatibility with a wide range of IP camera models and brands.
5. Video Quality and Resolution: DVRs, being analog-based systems, generally offer lower video resolutions compared to NVRs. IP cameras can capture and transmit higher-resolution video, allowing NVRs to record and display higher-quality footage.
6. Scalability: NVR systems offer more scalability compared to DVR systems. With NVRs, it is easier to add or remove IP cameras and expand the surveillance system as needed. DVR systems, on the other hand, may require additional hardware or configuration changes to accommodate changes in camera count.
7. Storage and Bandwidth: DVRs typically store recorded video footage on internal hard drives within the DVR unit itself. NVRs, on the other hand, can store video footage on both internal and external storage devices, such as network-attached storage (NAS) systems. NVRs also offer more flexibility in managing bandwidth, as video streams are transmitted over the network.
8. Remote Access: Both DVRs and NVRs generally offer remote access capabilities. However, NVRs, being network-based, often provide more advanced remote viewing options, including mobile apps and web browser access, allowing users to monitor and manage the system from anywhere with an internet connection.
When choosing between a DVR and NVR system, consider factors such as the type of cameras you intend to use (analog or IP), desired video quality, scalability needs, network infrastructure, and budget. Understanding the differences between these systems will help you make an informed decision based on your specific surveillance requirements.
What does megapixel or MP mean in regards to cctv cameras?
In the context of CCTV cameras, the term "megapixel" or "MP" refers to the resolution of the camera's image sensor. It indicates the number of individual pixels the camera's sensor can capture and is used as a measure of the camera's image quality and level of detail.
A pixel is the smallest unit of a digital image, and the more pixels a camera's sensor can capture, the higher the resolution of the resulting image. In other words, a higher megapixel count means more image detail and clarity.
For example, a 1-megapixel (1MP) camera has a resolution of approximately 1 million pixels. Common megapixel resolutions for CCTV cameras include 2MP (1080p Full HD), 4MP, 5MP, 8MP (4K Ultra HD), and even higher resolutions.
Here's a general guideline on the image quality and typical usage of different megapixel resolutions:
- 1MP (720p HD): This resolution provides basic image quality suitable for general surveillance applications where detailed image capture is not a high priority.
- 2MP (1080p Full HD): This resolution offers higher image quality with increased detail and clarity. It is widely used in various applications, including retail stores, offices, and outdoor surveillance.
- 4MP and 5MP: These resolutions provide even higher image quality, capturing more detail and allowing for greater zooming capabilities during playback. They are suitable for applications where finer details need to be observed.
- 8MP (4K Ultra HD): Cameras with 8MP resolution offer exceptional image quality, providing highly detailed and crisp images. They are often used in applications where precise identification or monitoring of objects or individuals
It's important to note that while megapixel count is an important factor in determining image quality, other factors like lens quality, sensor sensitivity, and image processing capabilities also influence the overall performance of a CCTV camera. Evaluating these factors along with the megapixel resolution will help you choose a camera that best meets your surveillance requirements.
What is a good frame rate or fps for cctv cameras?
The frame rate or frames per second (fps) refers to the number of individual frames captured by a CCTV camera in one second. The frame rate plays a crucial role in determining the smoothness and fluidity of the recorded video footage. The appropriate frame rate for a CCTV camera depends on the specific surveillance requirements and the level of detail needed in the captured video. Here are some general considerations:
1. Standard Frame Rates: Common standard frame rates for CCTV cameras are 30 fps (frames per second) and 25 fps. These frame rates provide smooth video playback and are suitable for most general surveillance applications.
2. Real-Time Monitoring: For real-time monitoring scenarios where capturing every detail and movement is critical, higher frame rates are preferred. Frame rates of 30 fps or higher can provide smoother and more responsive video feeds, enabling better situational awareness and capturing fast-moving objects or individuals more accurately.
3. Recording vs. Live Viewing: In many cases, the frame rate for recording video footage may be different from the frame rate used for live viewing. While a higher frame rate is beneficial for live monitoring, it may result in larger file sizes and increased storage requirements. For recording purposes, a frame rate of 15 fps or higher is generally considered sufficient, depending on the specific application and desired level of detail.
4. Bandwidth and Storage Considerations: It's important to consider bandwidth and storage limitations when determining the frame rate. Higher frame rates generate more data, which can impact network bandwidth and storage requirements. Assess the available bandwidth and storage capacity to ensure smooth video transmission and adequate storage capabilities.
5. Application-Specific Considerations: Certain applications may require higher frame rates. For example, in scenarios that involve fast-moving objects or require precise analysis of motion (e.g., sports arenas, traffic monitoring, or object tracking), higher frame rates, such as 60 fps or even higher, may be necessary to capture critical details accurately.
It's important to note that the frame rate should be balanced with other factors like camera resolution, available network bandwidth, storage capacity, and processing power of the recording system. It's advisable to consult with CCTV professionals or consider the specific requirements of your surveillance application to determine the optimal frame rate for your CCTV cameras.
