PTZ Cameras: What To Look For
PTZ security cameras offer Pan, Tilt, and Zoom capabilities for more advanced and comprehensive surveillance. Because of their unique flexibility and broad coverage, PTZ cameras are often chosen to remotely monitor large areas such as parking lots or stadiums. If you are considering installing PTZ surveillance cameras for your property, here are some of the best PTZ camera features and benefits.
Large Field Of View
Depending on where you install your PTZ camera, it could have a 360 degree field of view. In addition, most cameras can be pre-programmed to provide specific viewing angles at pre-determined times. Pan and Tilt can also be pre-programmed. Thanks to this, PTZ cameras can do the job of a multi-camera installation, making them a cost-effective and smart alternative for large area surveillance and protection.
Motion Tracking
Most PTZ cameras come with built-in tracking which can be set to detect motion and track a person or object, automatically panning, tilting or zooming to follow the person or object as it moves. This feature can prove invaluable should a theft or vandalism occur on your property. When choosing a PTZ camera, full motion tracking capabilities is a must.
Night Vision
This is an important feature in nearly all security cameras, but especially in areas with poor lighting conditions. The modern, more advanced PTZ cameras can capture images in total darkness thanks to LEDs and special IR filters. The small LEDs emit infrared light, which is not visible to the human eye, but with the special IR filter, the camera sees a well lit area.
Remember that a PTZ camera that is rated for a detection range of 600 feet or more will usually be rated for a max range of 400 feet for night vision. Also, it is recommended that you set up your PTZ cameras in the same lighting conditions they will be recording in, whether dark or light.
Weatherproof
If you will be installing PTZ cameras outdoors, they must be weatherproof. Most PTZ cameras are designed to withstand harsh elements, but it is wise to double check the specifications to ensure their durability. Weatherproof PTZ cameras can be installed in very remote locations such as rooftops or the sides of tall buildings.
Powerful Zoom
PTZ security cameras have a detection ability that ranges from 150 feet (on the low end) up to 1,000 feet (on the higher end). The ability to zoom in on a person or object ranges from 12X to 36X for higher level PTZ Speed Domes. This makes them ideal for large parking lots or building tops as it allows the camera to be discreetly out of sight while still providing the option to zoom in for a better picture of what is happening.
Tamper Resistant
The best place for a PTZ camera is mounted high above the ground, which enables the best view possible, a wide 360 degree range, and added protection. As mentioned, most PTZ cameras are built tough, with rigid metal housings and high-strength polycarbonate domes that are virtually shatterproof to vandals.
Alarm Inputs
Most PTZ cameras have four alarm inputs, which connect to other important devices (ex. motion detectors, door contacts, glass break sensors). The camera can be programmed so that when activity occurs in a given area, other programmed activity is halted in order to zero in and record what is going on.
Auto Focus
The good PTZ cameras will have full range auto focus built in. This ensures clarity no matter where you pan, tilt or zoom. In addition, most have an auto adjust IR LED that quickly focuses the picture when moving the camera in areas of complete darkness. This feature is almost always missing from cheaper cameras.
Simplified Installation
Because they can cover a wider area, it may be more cost-effective to install a couple PTZ cameras to monitor your property (ex. parking lots, garages) rather than implementing several fixed security cameras. You can save on both the initial cost and installation of your system.
High Definition Options
Higher end PTZ Speed Domes are also available in IP versions, which will deliver resolutions from 720i to 1080P, and with HD-SDI technology, which provides high definition video in full 1080P resolution. The HD-SDI PTZ cameras are easier to install and maintain than IP cameras since they are installed and set up exactly the same way as standard analog cameras.
These types are only recommended when you need the highest resolution images possible. They require 2-4 times as much hard drive space as regular analog security cameras and are rather expensive for large installations.

Security Cameras: Types, Housing & Features
Shopping for security camera systems may seem like a one-size-fits-all deal, but, unfortunately, it is not. Because there are a plethora of security camera types and surveillance features to be considered, it will take some time to decide. Evaluate your security needs, do some research and weigh your options. To make it easier, we will break down the different types, housing, and common features of security cameras.
Types
The following are the advantages and disadvantages of common security camera types.
- Fixed – As the name suggests, fixed cameras are positioned to capture an image and are always pointing in the intended direction. Because these do no move, they are more reliable than PTZ cameras and can be optimized with different housing and features.
- PTZ Cameras– PTZ stands for Pan, Tilt, and Zoom, thus, these cameras can be remotely positioned (thanks to specially designed motors and gears). These cameras may be set to automatically patrol an area, but they seem to be most effective when manually controlled.
For zoom capabilities, 32X is fairly common, although some higher end cameras may have a greater zoom range. While a greater zoom range is helpful when covering a large area, it is not always necessary.
However, there are some downfalls. Because PTZ cameras can adjust its viewing range, there are chances that they may miss something. Also, zoom decreases the size of the area being covered, and the camera can only be facing one direction at a time.
- 360-Degree Cameras – Also known as virtual PTZ, the 360-degree camera utilizes several high resolution fixed cameras in a single housing (usually dome). The images are then stitched together and can be zoomed in on after recording (zoom capabilities depend on the cameras being used). Because this type of camera can face in all directions, it can be an effective forensic tool.
Unfortunately, these cameras are often oversold as a universal solution, despite the fact that very few rooms allow for an unobstructed view in all directions. In applications where this camera is necessary, it often does wonderfully. However, a standard fixed camera can be paired with a lens to give it a 120-degree to 140-degree view. Also, many rooms are better monitored with cameras in corners (which only require a 90-degree field of view).
Housing
Once you have chosen the camera type, housing will come into play.
- Outdoor – Because of changing environmental elements, outdoor camera housing will be more weather resistant and include heaters and blowers.
- Dome – These are designed to obscure the direction of the camera to outsiders. This is often the best deterrent, making it a high priority and often a default selection. Most people assume dome cameras cover the entire area, making a fixed dome camera covering a door entrance more effective.
- Bullet – These are named for their sleek, cylindrical shape, often times resembling a bullet. This housing clearly shows the direction of the lens and generally provides a better picture. The front of the housing is close to the camera lens, decreasing reflections and making it easier to maintain. These act as deterrents as well, but are not as effective as ambiguous housing.
- Discreet – These completely disguise the camera as something else, such as a smoke detector or motion sensor, or as nothing at all, with pinhole or flush mount lenses installed in a wall or ceiling. Because they are hidden, they are not designed to be deterrents. These are often favored by architects looking to achieve a certain aesthetic.
All types of housing can be made to be vandal resistant, which is a step up from weather resistant. These types of housings are most commonly dome shaped and are designed to withstand unfriendly environments while still providing a usable image.
Features
The selection of features for your security cameras will depend on the application and your individual needs.
- Resolution – Resolution is measured in megapixels (millions of pixels) and is a major factor in picture and video quality. The higher the resolution, the more space required to store the images and processing power to manipulate it.
To demonstrate the differences in resolution, an old analog camera is about ¼ megapixel, an HDTV screen is just over 2 megapixels, and the highest resolution projected image in movie theaters (4K) is 8.8 megapixels.
While higher resolution cameras may be appealing, these do not respond as well as lower resolution cameras in low light situations. Thus, it is possible to buy more resolution than you need, unnecessarily increasing storage costs while decreasing performance.
- Low Light – Cameras with day/night capabilities are able to automatically adjust modes in various lighting situations. With advanced technologies, these cameras are able to produce usable images in near total darkness.
There are also cameras with infrared illuminators, which provide their own light source to obtain better images in low light settings. As mentioned, in order to improve low light performance, you will need to sacrifice some resolution.
- Lens Features – Varifocal lenses allow the installer to manually adjust the image magnification when installing the camera. However, many fixed cameras now come with remote zoom and focus (allowing the user to adjust the camera without physically going to the camera site), as well as auto-focus.
- Advanced Options – Other options to consider include wireless signal transition, ultra-high resolution, thermal imaging, explosion proof housings and more.

Indoor Security Tips
Security cameras placed outdoors allow you to monitor your property while acting as a deterrent for trespassing. But what happens if criminals proceed anyways?
Indoor security cameras will show you what happens when the intruders get in. Should theft or damage occur, you are left with video evidence of the crimes to assist in capturing the criminals.
For everyday use, indoor security cameras help to monitor daily activities, such as kids returning home from school, or checking in on pets while you’re at work.
While there are several benefits of indoor cameras, it may be difficult discerning the most effective places to install them. Here are some helpful tips for choosing the best locations for your indoor security cameras.
Statistics show that the most common entry points for burglars are through first-floor doors or windows, thus, your main entrances should be your top priorities. The front door, back door, garage door, and other first-floor exterior doors and windows should be equipped with some type of security (ex. locks). If possible, installing security cameras to cover all of these spots would be ideal.
- One of the most common places for an indoor security camera is in a high traffic area that provides coverage for as many areas as possible. Try to find the right angle and placement for a camera that will give a bird’s eye view of the larger area. For example, the family room may have views of the kitchen, back door, garage door entrance, and possibly even the front door.
- For larger homes or homes with a second or third story, additional security cameras may be necessary to sufficiently cover the interior of the home. Expansive one story homes may need multiple cameras to cover different rooms and entrances, while multiple story homes may need more cameras to cover each level.
- If an extensive security camera system does not fit within your budget, choose key areas that are highly targeted by burglars and install cameras there. For example, the family room often houses expensive televisions and electronics. Or if you have a family safe, you can place a camera in that room for added security.
- Once you have chosen the locations for your cameras, be sure to install them out of reach. Not only will this help to get a better view, but it will also help to prevent any damage of theft. If your security cameras are easily accessible, burglars may destroy them to eliminate evidence, or possibly steal them.

Transit Security Camera Systems: Aiming To Keep You Safe
Transit stations receive lots of foot traffic, with people taking advantage of its low cost and convenience. Unfortunately, these public transportation systems are also highly targeted for graffiti, thefts, assaults, and terrorist attacks. In an effort to fight back, an influx of advanced security cameras and high quality equipment have arrived.
Upgrading security camera systems to the latest technology produces better response times, heightened image quality, and, consequently, better suspect identification. With these sophisticated features, rider and driver safety is better preserved, deterring crimes and catching suspects faster.
An upgrade to IP systems from analog systems provides better, high resolution pictures and a way to wirelessly archive footage. Reviewing footage is simplified, allowing easy tagging of potential evidence. Power over Ethernet (PoE) technology is helpful in the sense that separate power cables are unnecessary, consolidating functions and cutting costs.
Security cameras installed closest to the driver booth enable audio function with built-in microphones. With this, direct communication to and from command centers is permitted and more efficient responses to problematic events can be delivered. Vandal proof security cameras help to maintain function if physical tampering occurs.
Wide angle camera lenses help increase the viewing field while decreasing the number of security cameras needed. With wide angle camera lenses and proper placement, blind spots can be minimized. Overall cost of the security camera system will go down because of the reduction in security camera needs.
Infrared/night vision and thermal imaging proves extremely beneficial transit systems, subways especially. These features help to see in darkness and detect warmth. Used in search and rescue efforts, an unconscious person can be found via thermal cameras. In cases of shootings, the heat from a recently fired gun will help locate the weapon, if discarded at the scene.
An excellent monitoring system is vital to the overall security camera system, providing remote viewing of the live feed and giving local authorities to access footage as necessary.
Overall, the security camera systems for public transit stations will help clear any liability issues or potential attacks or abuse. This will help protect both workers and civilians alike, helping to catch suspects faster and possibly prevent crimes before they happen. As our technology continues to improve, crime rates should continue to drop.

Optimal Features Of Dome Cameras
Dome security cameras have been in demand lately. This spike in sales and usage is most likely due to its compact design and cost-effective prices. But just because these cameras are affordable does not mean they skimp in the features department.
You can find dome cameras equipped with fantastic features for a reasonable price. PTZ (Pan, tilt, zoom) capabilities are common in dome cameras. This allows a single dome camera to reach a wide viewing range, possibly eliminating the need for multiple cameras in a given area. The zooming abilities can zero in on specific details which can be significant in identifying a culprit.
The inconspicuousness of the dome camera is often cited as a selling point. Truth is, nowadays, you know a dome camera when you see it. The tinted dome covering is a more optimal feature of the dome camera. While the actual camera is easy to spot, it is nearly impossible to tell which direction the lens is pointed. Furthermore, some dome cameras employ a tracking component, so a person could not suspect the camera is tracking his or her movements.
Due to varying light in different settings, dome cameras usually have infrared, low light or day/night vision to produce better pictures throughout the day and night. The IR irradiation distance depends on the camera so paying close attention to specifications is important.
Most dome cameras are vandal proof, adding built in security to your camera investment. If the environment permits, you may be able to install your dome camera out of reach to minimize the possibility of vandalism. However, in some areas, it is inevitable to place the dome camera on a wall or a low ceiling. The vandal proof, tinted dome then comes into play, protecting your camera from any possible damage or destruction from powerful blows.
Often referred to as the “eye in the sky,” dome cameras offer functionality in an appealing package. If you have any questions regarding dome cameras, please call us at 1-888-203-6294 and our staff will gladly assist you. You may also visit us at SecurityCamExpert.com to browse our inventory of dome cameras and more.
