When installing outdoor CCTV cameras, it's essential to consider a few key factors. Firstly, choose cameras that are weatherproof and durable. Proper camera positioning and mounting are vital to ensure effective coverage while preventing tampering. Adequate lighting in outdoor areas can greatly improve camera performance. For expert advice and tailored solutions, SAS Security offers free site surveys to recommend the best camera options for your specific needs, making the installation process easier and more effective.

Under UK data protection law, using recording equipment like CCTV or smart doorbells to capture video or sound recordings outside one's property boundary is not inherently in breach of data protection regulations. However, it is recommended that individuals aim to position their CCTV cameras in a way that avoids capturing their neighbors' homes, gardens, shared areas, or public streets, although practical constraints may make this challenging. When individuals do record images and audio beyond their property boundaries, they are advised to assess the intrusiveness of their activities. If possible, they should consider repositioning their cameras or applying filters or privacy blocks to mitigate intrusiveness. It's important to note that data protection laws do apply in such circumstances, and there are guidelines to follow, even though enforcement may prove challenging.

At SAS Security, we take pride in offering a comprehensive security solution, and that includes ensuring homeowners are well-equipped to use and manage their Hikvision cameras effectively. Every installation we undertake goes beyond just setting up the system. It includes a personalised demonstration and on-site training to equip homeowners with the knowledge they need to maximise the benefits of their CCTV system. We understand that technology can sometimes be intimidating, so our expert team is dedicated to making sure you feel confident in using your Hikvision cameras. We're here to answer your questions, address any concerns, and ensure you're in control of your home security. With SAS Security, it's not just about the equipment; it's about your peace of mind."

The number of CCTV cameras a UK house needs depends on the property's size, layout, and security objectives. A typical recommendation is to cover key entry points, such as front and back doors, and strategic areas like the driveway, main living areas, and back garden. A small to medium-sized house may require 4-6 cameras for comprehensive coverage. However, larger properties or those with unique features may need more cameras. It's essential to conduct a security assessment to determine the ideal camera placement and quantity to meet your specific needs.


For businesses, the number of CCTV cameras required can vary significantly based on the size and nature of the establishment. Small businesses might suffice with 4-8 cameras, focusing on entrances, cash registers, and main areas. In contrast, larger commercial properties, warehouses, or manufacturing facilities could require a more extensive network of cameras, potentially needing 16-100+ cameras. The exact camera count depends on the business's security priorities, layout, and surveillance goals, making a professional security assessment essential to determine the optimal camera quantity.

General Questions

At SAS Security, while we acknowledge the availability of DIY security solutions, it's important to note that these systems can lead to significant problems if not installed correctly. They often use components of lower quality, which may compromise the effectiveness of your security. Even minor installation errors can create vulnerabilities that may go unnoticed until a security breach occurs. To avoid these potential issues, we strongly recommend professional installation. Our experts not only ensure proper setup and integration but also use high-quality components, guaranteeing that your security system functions optimally and provides the protection you need. Your security is too important to leave to chance, and professional installation is the best way to safeguard your home or business effectively.

The flexibility of these systems ensures that you can adapt and grow your security infrastructure to meet changing requirements, providing a future-proof solution for your home or business.

The main difference between wireless and wired security systems lies in how they transmit data and power. Wired systems use physical cables for connectivity, while wireless systems rely on wireless signals.

Wired Security Systems:

  • Depend on cables for power and data transmission.
  • Typically require professional installation due to wiring complexity.
  • May be more reliable as they are not susceptible to wireless interference.
  • Can be more challenging to install in existing buildings due to cable routing.

Wireless Security Systems:

  • Operate wirelessly through radio signals or Wi-Fi.
  • Offer easier installation as they do not require extensive wiring.
  • Are more flexible and adaptable, making them suitable for both new and existing structures.
  • May be vulnerable to signal interference, although encryption and security measures help mitigate this risk.

The choice between wired and wireless systems depends on your specific needs, property layout, and the level of convenience and flexibility you require for your security setup.

The specific warranty coverage can vary between manufacturers.

For Hikvision systems, they usually come with a manufacturer's warranty that covers the equipment. Hikvision's warranties often range from 2 to 3 years, depending on the product.

Ajax offers a 2-year manufacturer's warranty on their security system components, providing coverage for their high-quality wireless alarm equipment.

Texecom, known for robust security solutions, also provides a 2-year manufacturer's warranty on their security equipment, ensuring the reliability of their systems.
