Since it is a matter of security, you have to be very careful while purchasing a CCTV camera. Some of the key factors to consider are mentioned in this ultimate guide. Read the information thoroughly to choose a model suitable for your requirements.
4 Key Points to Know For Choosing The CCTV Cameras
Factor 1. Choosing the camera type: Dome vs Bullet
As the name suggests, they have a dome-shaped protective encasing. It protects the lens from vandalism and also maintains the lens in the proper position. They are generally installed on a ceiling or under the roof overhang. In some cases, they can be installed on a wall. As they are discreet and unobtrusive, they are perfect for outdoor surveillance.
They have a cylindrical shape and are larger in size. It is used for both indoor and outdoor surveillance. As their appearance is not discreet, anyone can know that the place is protected by a security system.
Factor 2. What to choose: Analog or IP Camera?
Analog cameras as the traditional type of CCTV cameras. It will send the video through cable to either DVRs or VCRs. When it comes to IP cameras, they are digital cameras that send signals over the cable and store in the network for a few weeks. Most of the security cameras come in hybrid systems that combine both analog and digital cameras.
Factor 3. Choose the Camera Resolutions that meet your needs
A robust and high-quality camera is necessary for proper surveillance, tracking and monitoring. To check the quality of the camera, you have to look at the resolution specifications. It is usually measured in terms of pixels. Higher the pixel count, clear will be the details of the video (live or recorded).
For example – a 2MP image has 1920 (width) and 1080 (height). When multiplying these two numbers you will get the total number of pixels i.e., 1920 x 1080 = 2,072,600.
Apart from that, height of an image is also considered as resolution. In that case, 1080p resolution represents an image with 2 million pixels.
In most of the cases, 1280 x 720 resolution is sufficient. But if you are not budget constrained, then full HD resolution of 1920 x 1080 pixels provides a very clear image (even when zoomed). Latest cameras have been providing 4K quality which is capable of providing highest quality video content. A brief description of these two resolutions is provided below for your reference.
4. Other Features which you should consider
The below-mentioned factors can be helpful for more efficient cooling:
1. Motion Detection
This is one of the most-demanding features of a security camera. It is suitable for areas where continuous monitoring is required with fewer people coming or going. This feature enables you to configure the cameras to start recording only when they detect any motion on their field of view. So, only content relevant will be stored and archived which helps you replay them whenever you want.
2. Night Vision/Low-Light Cameras
Most of the theft usually happens during the night. If you want to secure your home at that time of hours as well, then choose a CCTV camera with night vision feature. It can clearly capture the image and video of the burglary, even if there is no sufficient light or completely dark. This feature is suitable for everyone. However, it is even more suitable for commercial spaces.
3. Real-Time Alerts
Apart from video coverage and recording, some security cameras can provide alerts when there is a breach or motion in the area. Based on the functionalities, it can either send an email or text alert when it notices any abnormal movement. Some CCTV cameras can also send alerts to many people at once (number of persons using or included in that app). Some send emails as well as a failsafe.
4. Weather Resistance
If you are choosing an outdoor camera, then make sure it can withstand the harsh weather conditions like sunlight, rains, ice storms, high winds and freezing temperatures. IP (Ingress Protection) represents the capability of a camera’s resistance to surrounding weather conditions like sun, dust and water. Among the two numbers, the first one represents the camera’s capability towards solids and the second one describes liquid resistance.
Apart from the camera, make sure the hardware included with the camera should also withstand the weather conditions. The camera you choose should be capable of handling weather conditions for an entire year and several years.
5. Mobile App Capability
Most of the home surveillance cameras can be operated through tablet/smartphone through an App. Apart from letting you watch the live streaming, this App lets you customize the camera functionalities like adjust motion, detect sound and others. Check out whether the app is easy to operate before making the purchase.
6. Pan, Tilt and Zoom Capabilities
Often called PTZ, these cameras are suitable for monitoring common areas like parking places, gardens, common halls, and others. It not only focuses on monitoring but also keeps an eye on suspicious activity.
