PTZ cameras are an investment anyone in media production should think of installing. However, where do you start if it’s your first-day buying PTZ cameras? Here is everything you need to know.
What is a PTZ Camera?
They refer to pan tilt zoom cameras mainly used in media to film and stream quality videos and surveillance purposes. What is unique about these devices is that you do not have to operate them in a near position but can do so at a distance. You can use a PTZ remote control to adjust several cameras seamlessly. Cameras could be mounted on a tripod or the ceiling regardless of their position.
Nevertheless, how do the PTZ cameras work, you may ask. The devices have three mechanisms for seamless movement:
- Pan: this feature allows switching between right and left and monitoring large areas. Some PTZ models come with 360 degrees movement features.
- Tilt: This feature allows you to cover beyond 180 degrees for a vertical viewing range.
- Zoom: the feature integrates lenses that allow you to focus on a particular activity and zoom on various objects without sacrificing quality.
Types of PTZ Cameras
There are several PTZ models in the market, including:
- PTZ camera outdoor models can still work under harsh conditions or during bad weather because they are designed with waterproof exterior mechanisms and have a unique IP rating that shows guaranteed adequate rating with protection against snow, rain, and wind.
- A Wireless PTZ camera is ideal for surveillance as it transmits quality videos even in tight spaces. With the wireless models, you eliminate the need for cables. You can use these models to transmit videos over WiFi. They are perfect for outdoor monitoring.
- IP PTZ cameras do not need to integrate with hardwire connections: they are wireless, and installing them is quick.
- PoE PTZ camera refers to power over Ethernet models and needs a single wire to transmit power and an internet connection for functionality.
- Analog PTZ camera models record footage through DVR and transmit using a digital video recorder then stored. In addition, such models include CCTV cameras that convert, compress, and save media that you can view later.
What to Look for in Buying a PTZ Camera
CCTV images and media from other recorders may be of low quality and resolution. It means that they may not be ideal for professional use, thus the need for PTZ cameras. If you are looking to buy a quality PTZ camera model, refer to the following as your checklist:
- The lens and quality should be video-optimized for quality and color images to avoid distortion as you zoom and tilt across all angles.
- Find out the type of cabling needed (wireless, WiFi, or PoE).
- Check the sensor: the provider should guarantee high performance with little or no noise, high sensitivity, and excellent resolution even in low light.
- Are you prone to harsh weather – do you need waterproofing, or should you consider operating temperatures?
- Processing speed: does the camera allow seamless syncing of media in milliseconds for both videos and audio. Check how fast this works and if you can adjust settings like noise reduction, exposure control, white balance, and focus on imaging.
- Find out how you can configure the system – do you need professional services, or can you DIY?
- A smooth pan-tilt-zoom mechanism should be quiet, with an option to adjust and fine-tune to the desired degree. In addition, it should guarantee that you will get the right shots at all times.
Finally, communicate with the provider to guarantee that the model is quality and will deliver excellent media – you can opt for the manufacturer’s guarantee services. You can count on HoneyOptics for all your PTZ camera needs and guidance.
Resolution and Zoom
Modern PTZ cameras must have multiple quality outputs under different focusing and resolutions. These are:
- HDMI, SDI, and CVBS: the resolution in these outputs can be made by integrating the yellow dial at the back of the camera. You can also use the chart at the device’s bottom to facilitate seamless correlation resolution to the DIAL indicators.
- USB: you can fix this type of resolution using an AMCAP-like tool. However, you should pay attention to fine-tuning the USB settings.
Since Zoom conferences are the new norm, you can control everything as you end your Zoom meeting and video conferences with PTZ cameras. Furthermore, since Zoom is designed for virtual meetings, you cannot go wrong with PTZ cameras to convey excellent media for your remote teams.
If you want to deliver live quality media, PTZ cameras have the following protocols:
- HTTP live streaming protocol –Apple designs these for Apple TV, Macs running OSX, and iOS devices.
- Adobe’s HTTP Dynamic streaming –HDS protocols facilitate on-demand and adaptive delivery of bitrate videos in high stands like MP4 instead of the conventional HTTP.
