How PTZ cameras work
PTZ stands for pan, tilt and zoom. These controls let you change the camera's viewing direction and zoom remotely, from a recorder, a keyboard or a phone. The cameras capture high-resolution images, so zooming in on a number plate or a face still gives a usable picture. Essatech supplies, installs and services PTZ cameras in Hyderabad and Visakhapatnam as part of its CCTV solutions.
Features buyers look for
Digital pan and zoom let you focus on a selected part of a high-resolution image. Many models also store preset positions and run automatic patrols between them, so the camera watches several spots when nobody is steering it. The main features are:
- Remote direction control
- Zoom control
- High-resolution image capture
- Digital pan and zoom within an image
- Ultra-low-bandwidth surveillance streaming
- Full-quality recording of the full field of view
When a PTZ camera is the right choice
A PTZ camera is not always better than a fixed one. It can watch only one place at a time, so a wide area with several important spots may need fixed cameras for constant recording and one PTZ camera for close-ups. We often use this mix. PTZ suits places where an operator needs to follow a person or vehicle, such as a car park, a yard, a hotel forecourt or a shopping complex. Fixed cameras suit doors and counters that must be recorded all the time.
Where PTZ cameras are used
PTZ cameras are used for surveillance at these locations:
- Offices
- Shopping complexes
- Traffic signal points
- Hotels
- Commercial areas
- Hospitals
- IT sector premises
Brands and recorders
Essatech provides PTZ camera and PTZ dome camera solutions, along with digital video recorders (DVRs) and network recorders. Available brands include Hikvision, Honeywell and CP Plus. We match the camera to the recorder, because the control and the recording must work together.
What you get from Essatech
We deliver PTZ systems as a complete job:
- A free site visit to decide where a PTZ camera adds value
- A mix of fixed and PTZ cameras, where it gives better cover for the money
- Supply, mounting on poles or walls, cabling and power
- Setup of presets, patrol routes and remote viewing
- A handover on how to control and play back
- Service visits and repairs afterwards
Testing and upkeep
A PTZ camera has moving parts, so it needs more care than a fixed one. At each service visit we check pan, tilt and zoom through their full range, listen for motor noise, check the presets and patrol routes, clean the dome, and test recording. Worn mechanisms are replaced before they stick, because a camera that cannot turn is a camera that cannot follow.
Why buy from Essatech
Essatech has been in business for more than 15 years, and its licensed team has 80 years of combined experience in fire safety and security. One team surveys, supplies, installs and services your cameras, so there is one contact if one needs attention.
For builders, architects, MEP consultants, corporates, industries, hospitals and defence
Industries and commercial building owners use PTZ cameras on yards, car parks and forecourts, where an operator must follow a vehicle or a person. Builders and architects should provide poles, power and network at the design stage. Hospital owners use them on campus roads and parking, with fixed cameras covering entrances and pharmacies. MEP consultants can send the camera schedule and we price PTZ and fixed cameras against it. Corporates use PTZ for campus roads and parking. Defence establishments, including Navy and Army perimeters and gates, use PTZ cameras, and we quote within their security and vendor rules.
What decides the cost
A PTZ camera costs more than a fixed one. A quote depends on:
- The number of cameras, their resolution and their zoom
- Indoor or outdoor housing, and wind and weather ratings
- Poles, brackets and cable length
- The recorder, storage and any control keyboard
