Installing video surveillance in the entrance of an apartment building is no longer a luxury, but an urgent necessity to ensure the safety of residents and protect common property. A modern entrance video surveillance camera helps prevent vandalism, theft, and records all visitors around the clock. However, due to specific operating conditions — poor lighting, temperature fluctuations, high humidity, and the risk of intentional damage — choosing the equipment requires special attention. According to the recommendation of the ComfortShop editorial team, it is worth determining the key technical parameters in advance that guarantee stable operation of the system under any conditions.

Features of Video Surveillance in an Entrance
The main difference between entrance video surveillance and outdoor or office surveillance is operation under constantly changing lighting conditions. During the day, light may enter through windows on stairwells, while at night only emergency lighting, which is often dim, is active. The camera must have high matrix sensitivity and effective infrared illumination to provide a clear image even in near-total darkness.
Another critical factor is vandal resistance. Unfortunately, hooligans often try to damage, paint over, or tear down a security camera in the entrance. Therefore, the device's housing must be as durable as possible, preferably metal, and the design should include a minimum of protruding elements that can be grabbed. It is also worth paying attention to models with a vandal-resistant cable hidden in the bracket or ceiling.
Humidity and dust should also be considered separately, especially if the front door is frequently open or the camera is mounted directly near the entrance. Protection according to the IP65 or IP67 standard would be an ideal solution, guaranteeing uninterrupted operation of the electronics in such challenging conditions.
Types of Cameras and Their Design Differences
The market offers two main form factors that are best suited for an entrance: bullet cameras and dome cameras. Each type has its advantages and disadvantages, so it is important to understand which device will provide maximum video surveillance efficiency.
Dome cameras are considered a classic for indoor spaces. Thanks to the hemispherical housing, it is difficult for an intruder to determine which direction the lens is pointed, which serves as an additional deterrent. They are compact, easy to install on the ceiling, and have an aesthetic appearance. However, their plastic dome may become cloudy or scratched over time, degrading image quality.
Bullet cameras typically have a long-focus lens and powerful illumination. They are best used for monitoring long corridors or entrance doors from the street. The main advantage is the ability to point the lens exactly at the desired area, while the disadvantage is that they are more noticeable and require reliable wall mounting.
Which type to choose for a typical entrance?
For a standard vestibule in front of an elevator or a stairwell, ComfortShop experts recommend choosing a dome model with a wide viewing angle. If you need to clearly identify the face of a person entering from a distance of 5-10 meters, a bullet camera with a varifocal lens would be more appropriate.
Key Technical Specifications
Choosing a camera for an entrance should be based not only on appearance but also on the dry figures of the technical data sheet. They determine whether you will be able to see the face of an intruder or the license plate of a car near the entrance.
Matrix resolution. The minimum standard for a modern system is 2 MP (Full HD 1080p). This quality is sufficient for general overview. However, for detailed identification of individuals, it is better to choose cameras with a resolution of 4 MP (2K) or 5 MP. They allow digital zooming without significant loss of clarity, which is critical when analyzing archived recordings.
Light sensitivity and IR illumination. Since entrance video surveillance often operates in "day/night" mode, it is important that the camera has a mechanical IR filter. The illumination range should correspond to the length of the room, but 15-20 meters is usually sufficient. Pay attention to Starlight or ColorVu technologies, which provide color images even in minimal lighting.
Viewing angle. For tight vestibules, a wide-angle lens (90-120 degrees) is needed to cover the entire space without "blind spots." For narrow, long corridors, narrow-angle optics (60-70 degrees) are better, as they do not distort proportions at a distance.
Intelligent Functions and Recording
A modern best entrance camera is not just an "eye" but a full-fledged analytical device. The presence of a motion detector allows saving hard drive space by recording only moments of activity rather than an empty corridor for hours. This simplifies searching for events in the archive and extends the life of the storage device.
To enhance security, the "alarm input/output" function, to which a door opening sensor can be connected, is useful. In case of unauthorized entry, the camera will send a notification to a smartphone or activate a siren. It is also worth paying attention to WDR (Wide Dynamic Range) technology, which compensates for brightness differences when light from a window shines directly into the lens.
Regarding recording, there are two paths: network IP cameras recording to an NVR (Network Video Recorder) or to a cloud service. As ComfortShop reviewers note, for collective use by residents, a local recorder with an installed HDD is the most reliable, as it does not depend on the stability of the internet channel and does not require a monthly subscription fee.
Installation and Power Supply Recommendations
Proper installation is half the success of the entire security system. The camera should be placed at a height of at least 2.5-3 meters to make it difficult to reach by hand, but not flush against the ceiling, where warm air and dust accumulate. The optimal location is a corner above the front door, allowing you to see the face of a person entering rather than the back of their head.
Power supply is most conveniently organized using PoE (Power over Ethernet) technology if an IP camera is used. This eliminates the need to run a separate 220V cable to each point. A single UTP twisted pair cable, which transmits both video signal and electricity, is sufficient. In the case of analog systems (AHD/TVI), you will have to combine a coaxial cable with power wires.
Communication protection.
Cable routes must be hidden in a metal hose or plastic cable channel, as protruding wires are the primary target for vandals. The power supply and video recorder should be placed in a locked metal cabinet on the upper floors or in the electrical panel room, accessible only to responsible residents.
Conclusion:
When choosing an entrance video surveillance camera, it is important to maintain a balance between price and reliability, as the device will operate in an aggressive environment around the clock. The ideal choice would be a dome IP camera with a resolution of at least 4 MP, PoE support, powerful IR illumination, and a vandal-resistant housing. Do not skimp on matrix quality and moisture protection, as the peace of mind of all building residents depends on it.
Frequently Asked Questions
Which entrance video surveillance camera sees best in the dark?
For an entrance, it is best to choose a camera with IR (infrared) illumination and a Sony Starvis matrix, which provides clear color images even in minimal lighting.
Is a camera with a microphone needed for entrance video surveillance?
Yes, a camera with a microphone allows not only recording video but also capturing audio, which helps in cases of conflicts or thefts, but consider legal requirements regarding resident consent.
What resolution should I choose for a security camera in an entrance?
For an entrance, a resolution of 2 MP (Full HD) is sufficient, but if you need to recognize faces at a distance, choose 4 MP or 5 MP.
Is an outdoor camera suitable for installation in an entrance?
An outdoor camera with an IP66 or IP67 protection rating is suitable for an entrance if there is a risk of moisture or dust, but for dry rooms, a cheaper indoor model can be used.
