VS133 vs VS135 vs VS125 vs VS126: Which Milesight People Counter Do I Need?

Short answer: For a standard doorway with a ceiling at 3.5 m or below, choose the VS133-P if there is a PoE+ switch port at the door, and the VS135 if you need cellular, Wi-Fi HaLow or LoRaWAN instead, or its High Ceiling Mount version, which reaches 6.5 m. For a 2.2 to 6 m ceiling on a wired or 4G network, the VS125 is the stereo-vision option and the cheapest of the four. Above 6.5 m and up to 15 m — atriums, concourses, stadiums — the VS126 is the only one rated for the height, and the most expensive of the four.

Which Milesight people counter do I need?

Choose the VS133-P if the ceiling at the entrance is 3.5 m or lower and there is an Ethernet run with PoE+ to the door. Detection range is 0.5 to 3.5 m, which is what caps the mounting height. It gives up to four bi-directional counting lines, up to four detection areas with dwell time, and motion and dwell heat maps, and up to four units stitch across a wider entrance. It reports over HTTP(S), MQTT(S) or BACnet/IP from a single 10/100 Mbps RJ45 port.

Choose the VS135 if you want the same Time-of-Flight counting but a choice of how it reaches the network — it exists in PoE, cellular, Wi-Fi HaLow and LoRaWAN versions — or if the ceiling sits between 3.5 and 6.5 m, where the High Ceiling Mount version (2 to 6.5 m) is the only ToF answer. The PoE version stitches up to 8 devices across a wide entrance; other versions stitch up to 4.

Choose the VS125 if the mounting height is 2.2 to 6 m and you have Ethernet or 4G rather than a LoRaWAN gateway. It uses binocular stereo vision — two 4 MP sensors — and works down to 0 lux with its IR illuminators on. It stitches up to 16 devices, and its sheet lists gender recognition plus children/adult differentiation, the latter only at 2.2 to 4 m mounting height.

Choose the VS126 if you are mounting 6 to 15 m up: airport concourses, mall atriums, libraries, stadiums. Nothing else in this family is rated above 6.5 m. Two 5 MP stereo sensors give a 75.4° by 57.4° field of view, covering 10.40 × 7.80 m at a 10 m mounting height, and it stitches up to 16 devices.

VS133-P vs VS135: what actually changes?

Far less than the model numbers suggest, on paper. Both use second-generation ToF with a 940 nm invisible beam, both quote counting accuracy up to 99.8%, both cover 0.5 to 3.5 m at 98° by 80° in standard form with ±3.5 cm distance accuracy, both offer four counting lines and four detection areas, both are IP40, both run -20°C to +50°C, and both store up to a million records for CSV export.

Three things separate them. Connectivity: the VS133-P is PoE only, while the VS135 comes in PoE, cellular, Wi-Fi HaLow and LoRaWAN versions. Height: only the VS135 has a High Ceiling Mount version, trading field of view (60° by 45°) and distance accuracy (±6.5 cm) for reach to 6.5 m. Scale: the VS135-P stitches up to 8 units across a wide entrance, the VS133-P up to 4.

Neither is a camera. Both count with an invisible 940 nm ToF beam and collect no images, and both list GDPR alongside CE and FCC. The VS125 and VS126 work differently — binocular stereo vision with IR illuminators — and their approvals are listed as CE, FCC and RoHS.

Are any of these battery-powered?

No. Every model here needs a permanent supply, including the LoRaWAN ones. The VS133-P takes 802.3at PoE+, at 9.4 W typical and 23.8 W maximum. The VS135-P takes 802.3at PoE+ or 12 V / 2 A. The VS125-P and VS126-P take 802.3af PoE or 12 V / 1 A. Check that against your switch, because the VS133-P and VS135-P are the two that ask for PoE+ rather than plain af. Cellular versions take a nano SIM and still need local power.

Frequently asked questions

Can the VS133-P be mounted higher than 3.5 m?

No. Its detection range is 0.5 to 3.5 m, which caps installation height at 3.5 m. For 3.5 to 6.5 m, use the VS135 High Ceiling Mount version (2 to 6.5 m). For 2.2 to 6 m, the VS125 is rated. Above 6.5 m and up to 15 m, only the VS126 is rated.

Do Milesight people counters record video?

The VS133-P and VS135 use second-generation Time-of-Flight sensing with a 940 nm invisible light beam and collect no images; their approvals include GDPR alongside CE and FCC. The VS125 and VS126 use binocular stereo vision sensors with IR illuminators and operate at 0 lux; their listed approvals are CE, FCC and RoHS.

Which LoRaWAN frequency do I use in the UK?

EU868. The LoRaWAN version of the VS135 supports CN470/IN865/RU864/EU868/US915/AU915/KR920/AS923-1&2&3&4, in OTAA or ABP Class C mode. The VS133-P, VS125 and VS126 do not use LoRaWAN.

How wide an entrance can one unit cover?

It depends on model and mounting height. The VS126 covers 10.40 × 7.80 m at a 10 m mounting height. For wider entrances the units stitch together: up to 16 devices on the VS125 and VS126, up to 8 on the VS135-P, and up to 4 on the VS133-P and on other VS135 versions.

Which of these is the most accurate?

All four quote counting accuracy up to 99.8%, so the specs do not distinguish them on that figure. They do differ on distance measuring accuracy: ±3.5 cm on the VS133-P and on the standard VS135, and ±6.5 cm on the VS135 High Ceiling Mount version.

What power does each model need?

None are battery-powered. The VS133-P uses 802.3at PoE+. The VS135-P uses 802.3at PoE+ or DC 12 V / 2 A, with other VS135 versions on DC 12 V / 2 A. The VS125-P and VS126-P use 802.3af PoE or DC 12 V / 1 A, with the cellular versions on DC 12 V / 1 A.
