• Analytics cameras: These intelligent cameras use AI-powered video analytics to identify people, vehicles, objects, and specific behaviors. Analytics can help reduce false alarms and provide actionable insights that improve security operations.

Types of video surveillance systems

In addition to security cameras, there are types of video surveillance systems in which the cameras connect to and are managed through.

By understanding these types of systems, you can find the best solution that matches your business and security needs.

DVR systems

Digital Video Recorder systems are traditional systems that use analog cameras. DVR deployments transmit video from the camera to the recorder via a coaxial cable, where it is processed and stored.

DVR systems have limited scalability due to the required hardwiring to the cameras. They also have lower image quality than alternative solutions. However, these systems are suitable for those who need a low-cost solution and don’t have the funds for an NVR system with IP cameras.

NVR security systems

Network Video Recorders are designed to work with IP cameras. Unlike DVR systems, video is processed on the camera before it’s transmitted digitally over the network to the recorder, where it’s stored.

NVR surveillance systems are popular options for businesses because they support higher video resolution and can easily scale. They can also be remotely accessed via desktop or mobile, enabling a simplified management process.

These systems also support enhanced features such as AI analytics: zone monitoring, people, object, and vehicle tracking, face recognition, dwell times, queue monitoring, and more.

Which is better, NVR or DVR?

For most businesses, NVR systems are better. They scale easily, have fewer installation requirements, and offer greater video quality than their DVR counterpart. Remote management also makes these systems highly beneficial for large or multi-site businesses.

However, if you already have a DVR system and don’t have the budget to upgrade, consider a hybrid system to modernize without breaking your budget.

Cloud-based video surveillance

Cloud-based video surveillance systems don’t have a recorder. They store video footage and are accessible via mobile or desktop at all times. These systems still use IP cameras like NVRs, but send the processed digital footage directly to the cloud database via the local network.

Many organizations are moving towards cloud-based video surveillance systems because they require less hardware and are easy to scale. They are especially helpful for businesses with multiple sites.

Hybrid surveillance systems

Hybrid video surveillance combines elements of on-prem systems with cloud capabilities. These deployments are especially popular for businesses looking to upgrade without the costs of a complete replacement.

How to choose the right types of security cameras for your business

The best camera for one organization may not be the best fit for another.

Several factors should be evaluated before selecting surveillance equipment:

• Coverage requirements: Determine how much area you need to monitor and identify any critical entry points, blind spots, or high-risk locations. Larger spaces may require specialized cameras such as PTZ or multidirectional models.
• Location: Consider where the camera will be installed. Indoor and outdoor environments present different challenges, including weather exposure, vandalism risks, and mounting requirements.
• Lighting conditions: Evaluate the amount of available light throughout the day and night. Low-light environments may require infrared (IR) or other advanced night vision capabilities.
• Required image quality: The level of detail needed can influence camera selection. Identifying faces, reading license plates, or monitoring transactions often requires higher-resolution cameras.
• Analytics needs: If your organization wants to leverage AI-powered detection, occupancy monitoring, intrusion alerts, or business intelligence insights, choose cameras that support advanced analytics.
• Connectivity: Determine whether a wired, wireless, IP-based, or hybrid deployment best aligns with your network infrastructure and business requirements. And don’t forget to consider regulatory compliance requirements when choosing your cameras.
• Specific features: Certain applications may require specialized capabilities such as audio recording, active deterrence, thermal imaging, license plate recognition (LPR), or edge-based analytics

Which video surveillance systems are right for you?

Choosing the right type of video surveillance system for your business can have a significant impact on its operations and safety for employees, customers, and inventory.
