Modern IP systems offer far greater flexibility than analog solutions. A resolution of 2MP (Full HD) is today's minimum for recognizing details, while 4K cameras provide crystal-clear images even when digitally zoomed. Brands like DAHUA and EZVIZ offer reliable systems with excellent price-to-quality ratios.
Outdoor installations require IP66 or IP67 protection against moisture and dust. Night operation demands infrared (IR) illumination – a range of 20-30 meters covers an average yard. For indoor spaces, WiFi cameras from ANKER and FOSCAM models offer simple installation without cables.
NVR devices store recordings locally, while cloud services offer access from any device but require monthly subscriptions. For continuous recording, plan for 1-2 TB per camera for one month of archive. H.265 compression reduces storage requirements by up to 50% compared to the older H.264 standard.
Wireless alarm systems enable quick installation without intervening in walls. Quality PIR sensors distinguish people from pets up to 25kg, reducing false alarms. Brands like ELDES offer GSM modules that send notifications directly to your phone even when internet is unavailable.
Video intercoms with RFID readers combine visual identification with contactless access. For commercial buildings, biometric fingerprint or facial recognition readers prevent unauthorized entry. GEWISS and D-LINK offer solutions that easily integrate with existing network infrastructures.
Verify that the system supports expansion – a four-channel NVR with two cameras is better than a two-channel one without upgrade options. The mobile app must be intuitive and stable, as you'll use it daily. Avoid systems without local technical support – in emergency situations, every hour of waiting is too long.
