2. Install Cameras

  • Attach mounting hardware to surface where camera will be fixed.
  • Attach camera securely to mounting brackets.

Tips for Installing Security Cameras

Follow these tips when installing CCTV cameras:

  • Place cameras high up for wider field of view
  • Angle cameras to capture faces and license plates
  • Avoid pointing cameras into sunlight
  • Use sturdy mounting hardware for outdoor cameras
  • Install cameras in sheltered spots if outdoors
  • Use weatherproof housings and conduits where needed
  • Post warning signs to deter crime
  • Have at least one camera covering each entry point
  • Overlap fields of view between cameras
  • Light the area properly for night vision cameras

Wired vs Wireless Security Cameras

Deciding between wired or wireless security cameras comes down to pros and cons:

Wired Security Cameras


  • Reliable with no interference
  • Higher video resolution
  • Unlimited cable runs


  • More expensive installation
  • Cables must be hidden or secured

Wireless Security Cameras


  • Quick and easy installation
  • Flexible positioning
  • No cables required


  • Lower resolution video
  • Limited wireless range
  • Signal interference issues

So in summary, wired cameras provide better performance while wireless cameras are simpler to install. Mixing both systems gives you the best of both worlds.

How Do Security Cameras Work?

Security cameras have a lens to capture images, and a sensor that converts those images to video signals. The video footage is then transmitted either over cables or wirelessly to the recording device.

  • Analog Cameras – Convert light into analog signals along coaxial cables to DVR
  • IP Cameras – Digital video compressed and sent over IP network to NVR
  • Wireless Cameras – Digitally transmit footage over WiFi frequencies

The DVR or NVR receives the video signals and records them to a hard drive for viewing and backup. Smart features like motion detection and night vision are also built into security cameras.

Why You Need CCTV Installation

Trying to install a complex CCTV system yourself can be extremely difficult and risky. That’s why it’s highly recommended to hire professional CCTV installers.

Here are some key reasons you need CCTV installation services:

  • Expert knowledge – They’re familiar with all equipment, configurations and setup needs
  • Correct setup – Professionals will install the system properly the first time
  • Saving time – CCTV installation can take days which is time consuming
  • Neat cabling – Cables will be neatly run and concealed
  • Testing and commissioning – Extensive testing to ensure cameras work
  • Warranties – Professional installation provides workmanship warranties
  • Maintenance – Many companies provide ongoing CCTV maintenance

So rather than fumbling through a DIY camera setup, get the job done right by the professionals.

Where To Put CCTV Cameras?

CCTV cameras should be placed in locations that cover entry and exit points, high-traffic areas, and any vulnerable spots on a property. Ideal positions are overlooking building entrances, parking lots, cash registers, and warehouses. Cameras should also be angled to capture faces and license plates clearly.

How Many CCTV Cameras Do I need?

The number of CCTV cameras needed depends on the size and layout of the area needing surveillance, the camera capabilities and features, and the budget. A general guideline is 1 camera covering every 10-15 feet for interior spaces and 1 camera per 20-35 feet on exteriors. High-risk areas need more density. Home systems need 4-8 cameras while businesses may need 10-20 cameras or more for comprehensive coverage.

CCTV Installation Costs

The cost to install CCTV cameras can range greatly based on different factors:

  • System size – Number of cameras needed and area coverage
  • Camera types – Simple vs high resolution IP cameras
  • Installation complexity – Cabling needs, conduit, labor time
  • Additional hardware – Monitors, mounts, software etc.
  • Professional installation – Service fees and maintenance packages

For a small home system with 4 security cameras, total costs usually range from $500 – $1500.

Larger business installations with multiple high-end cameras, extensive cabling, and remote access features can cost anywhere from $2,000 up to $10,000 or more.

Keep in mind that professionally installed systems often come with warranties, maintenance and full service support.

Choosing a CCTV Installation Company
