What are PTZ CCTV Cameras?


Pan-tilt-zoom (PTZ) cameras contains mechanical parts that enable them to pan horizontally, tilt vertically, and zoom in and out. They are typically placed at guard stations where active staff can manage them using a remote camera controller. The primary usage of PTZ cameras is to monitor expansive areas that require a 180- or 360-degree view. Additionally, they can be programmed to automatically respond to motion or follow a predetermined schedule, depending on the camera and software. It is common practice to use PTZ cameras as part of a larger surveillance system; this allows the PTZ to track moving objects while the stationary camera records high-resolution images.

In contrast, “ePTZ,” which refers to a software capability, denotes a specific type of camera hardware. Unlike PTZ cameras, ePTZ security cameras use digital zoom to mimic the pan-tilt-zoom effect without physically moving parts. This feature eliminates the coverage gaps seen with older PTZ cameras and allows operators to focus on specific areas more easily. An ePTZ camera, capable of capturing the entire field of view and mimicking the PTZ effect, is a significant tool for systems that provide 360° coverage.

Case Study: Deployment of PTZ Cameras in Diverse Scenarios

This case study examines the implementation of Pan-Tilt-Zoom (PTZ) cameras across three distinct scenarios: a metropolitan public safety project, a large-scale industrial site, and a high-traffic retail environment. Each scenario underscores the technical specifications, challenges, and solutions provided by PTZ cameras, emphasizing their adaptability and efficacy in varied settings.

Pros and Cons of PTZ Security Cameras

PTZ cameras offer operators complete control over the camera’s field of view, enabling greater surveillance of broader regions. The controls allow operators to study moving objects and record detailed video as events occur over large areas.

To make an educated investment choice, here are some elements to consider when it comes to functionality, use case, pricing, and more.

Considerations for Traditional PTZ Cameras:

  • Field of View: PTZ cameras can pan, tilt, and zoom to cover large areas, but not simultaneously. They may occasionally miss capturing regions not directly in their view, potentially allowing events or intruders to escape unnoticed. To overcome this, look for PTZ cameras with automated motion detection and panning capabilities that can automatically detect and track persons or vehicles entering its range.
  • Camera Lifespan: PTZ cameras have multiple moving parts, making them generally less durable than fixed systems. When choosing PTZ cameras, consider this in the total cost of ownership. Opt for cameras built with durability in mind, such as those with IP66 weather certification and IK10 protection against direct strikes from vandals, hail, and flying debris, suitable for highly-exposed exterior installations.
  • Higher Cost: In some cases, multiple fixed cameras (such as fisheye cameras) may provide the same coverage at a lower cost compared to one PTZ camera. A 4K fisheye camera, for example, may be designed to cover the same area as a PTZ camera and offer digital zoom on high-resolution video, without the risk of being relocated erroneously.
  • Delay Considerations: A common issue that many PTZ cameras face is significant command delay. Be aware that excessive latency may occasionally cause PTZ controls to misbehave. Look for cameras that offer seamless and accurate controls with a quick reaction time that allows operators to adapt to scenarios as they occur in real-time.

Features and Advantages of PTZ Cameras:

  • Vast Field of View: PTZ cameras are used to monitor a vast area, often in combination with a fixed camera to eliminate coverage gaps. Depending on the model, cameras may move anywhere from zero pan/tilt to the complete 360 degrees pan and 180 degrees tilt. Some systems also offer digital pan and tilt, which allows for footage to be adjusted post-recording, albeit at a lower resolution.
  • Motion-Based Auto Tracking: This feature enables PTZ cameras to automatically adjust their range of view to follow moving objects. It is often best implemented in quiet locations with limited activity (e.g., a museum after closure).
  • Remote Camera Control: Traditional PTZ cameras can be manually and remotely adjusted to track suspicious activities. This allows users to alter the camera’s field of view without needing to be onsite. Typical control methods include mobile applications, joystick controllers, and computer software.
  • Zoom Capabilities: Most PTZ cameras feature optical zoom, used to observe and record distant objects like license plates or faces. Optical zoom (e.g., 20x, 30x, 40x) refers to the ratio of the maximum to the minimum focal length—the higher the number, the further the zoom.

Where PTZ Cameras are Widely Used:

PTZ cameras are employed in a variety of settings, including stadiums, large industrial yards, and other expansive outdoor areas. Here are some of the most common use cases:

  • Stadiums: Help ensure crowd safety during concerts, festivals, or sports events. Capture the action and manage seating sections, entrances, and key locations.
  • Parking Lots: Provide thorough coverage of large areas, focusing on important spots such as entrances, exits, and high-traffic areas.
  • Transportation Hubs: Increase public safety by monitoring platforms, ticketing areas, and waiting zones. Utilize facial recognition and scrutinize suspicious activities.
  • Parks: Enhance safety for park-goers, prevent vandalism and illegal activities, and monitor wildlife.
  • Train Yards: Secure operations, tracks, and storage facilities to protect assets, detect unauthorized entry, and respond to security breaches swiftly.
  • Storage Lots: Gain a bird’s eye view of sweeping areas from poles or towers. Monitor equipment, infrastructure, and identify suspicious activities.
  • Warehouses: Secure entrance points, loading docks, storage spaces, and inventory in warehouses and distribution facilities.
  • Loading Docks: Monitor loading dock activities, prevent unauthorized entry, and deter theft or tampering of goods in transit.

Types of PTZ Cameras:

  • PTZ IP Camera: Can be installed over WiFi or Power over Ethernet (PoE).
  • WiFi PTZ Camera: Communicates wirelessly to a network without a hardware connection, although they still need a power source. A robust WiFi connection is also recommended to avoid issues with latency and video quality.
  • PTZ PoE Camera: Uses an Ethernet cable that plugs into a PoE switch to obtain power and an internet connection, typically offering a significantly stronger connection than WiFi.
  • PTZ Analog Camera: Employs an analog video signal to collect surveillance footage, linked to digital video recorders (DVRs) via coaxial cables. These cameras often cannot send video data on their own and require a DVR to enable converting, compressing, and storing footage.
  • Outdoor PTZ Camera: Designed to withstand harsh temperatures and weather conditions, often enclosed in a waterproof shell with an IP certification indicating protection against natural elements.
  • Wireless PTZ Camera: Ideal for situations where it is difficult or costly to run video cables, these cameras can transmit footage wirelessly, typically over WiFi, although transmitter sets may be used to convert analog signals.

What to Consider When Buying a PTZ Camera:

  • Operator Presence: Will you have someone operating the camera at all times?
  • Storage Requirements: Do you have adequate storage? (Cloud, Hybrid Cloud, DVR, or NVR?)
  • Visibility Needs: What visibility do you need? (3MP vs. 4K resolution? Field of view? Low-light IR illuminators?)
  • Environmental Hazards: What sort of environmental dangers do you face? (Operating temperatures? Waterproofing?)
  • Installation Requirements: What does the installation require? (Supporting equipment? Professional system integrators?)
  • Cabling Needs: What type of cabling is required to support the system in terms of network connectivity? (PoE, WiFi, wireless?)
  • Pan and Tilt Capabilities: How much pan and tilt do you require? (Though a 360 pan may eliminate all blind spots, the corner camera wouldn’t need to capture the wall behind it.)
  • Deployment Environment: What environment will the camera be deployed? (Indoor, outdoor?)
  • Camera Type: What sort of camera best meets your needs? (Dome or Bullet?)
