Top 5 Surveillance Cameras in 2021
Top 5 Surveillance Cameras in 2021
Regardless of the purpose and location of video surveillance, the equipment must provide 100% situational awareness. We have compiled the TOP 5 outdoor surveillance cameras in 2021, among which you can choose the appropriate option.
Guidelines for buying
Outdoor cameras face changeable weather, temperatures, rainfall, thunderstorms, and intruders every day. Therefore, the equipment must be selected according to the risks.
General criteria
When choosing outdoor cameras, you need to consider the following characteristics:
- vandal-proof, reinforced case. Intruders often target outdoor equipment. Read more in our article “Anti-vandal cameras. Ten main selection criteria”;
- the presence of a protective and heating box. You can find out about the thermo-housing here;
- the presence of IR illumination. Street cameras work day and night. Therefore, in order for the quality of the shooting to be maintained 24/7, additional light is needed.
By meeting only these parameters, an outdoor camera will provide practical shooting. However, the video surveillance system can be further improved by choosing devices with the following additional characteristics.
Additional criteria
The following criteria can guarantee maximum quality and versatility of observation:
- rotating camera mechanism and panoramic shooting;
- the ability to shoot color images at night;
- availability of video analytics.
Video analytics turns ordinary monitoring into a “smart” organism capable of filming and evaluating what is happening around. For example, a cloud service from Faceter can:
- count the number of visitors in shops, offices, etc .;
- recognize faces;
- maintain “white” and “black” lists of visitors;
- monitor the work of employees;
- notify in case of detection of abnormal events.
All this becomes possible with the help of modern neural network technologies. You just need to install an outdoor IP camera and configure the system through the app.

Conclusion
Outdoor cameras should be PTZ, protected, and backlit. But for video surveillance to replace the security point, you need to add a video analytics function. Remember that without it, the cameras will simply see but not analyze the situation. The Faceter service can turn your video surveillance into a “smart” system.
